If you are spec'ing an R760 deployment, retrofitting a rack from 120 V to 208 V, or calculating CRAC capacity for an incoming shipment of 16th-generation Dell servers, this is the reference page you have probably been hunting across Dell's paginated manuals and half-finished forum posts to assemble yourself. We deal with the same problem every week — customers call us asking which PSU they should configure for their workload, why their 2,400 W Platinum spec'd out at 1,400 W in iDRAC, and whether the 3,200 W Titanium PSU they keep reading about is actually available for the R760 they are buying.

This page consolidates every published PSU option for the standard R760, separates out the R760xs and R760xa variants (which most refurb resellers blur together), shows the voltage derating rules Dell buries in footnotes, gives you the BTU/hr math for cooling planning, and walks through PSU sizing for two real configurations. Every spec is cited to the Dell Installation and Service Manual or to the Dell Technical Guide; every gotcha is one we have seen in the field.

Short answer: the standard Dell PowerEdge R760 supports up to two hot-plug PSUs in eight published wattage tiers — 700 W and 1,100 W and 1,800 W and 2,800 W Titanium, plus 800 W and 1,400 W and 2,400 W Platinum, plus a 1,100 W −48 to −60 V DC option for telco. The 3,200 W Titanium PSU is exclusive to the R760xa GPU server and requires 277 Vac or 336 HVDC input. Low-line 100–120 Vac deployments derate the 2,400 W to 1,400 W, the 1,400 W to 1,050 W, and the 1,100 W Titanium to 1,050 W; three of the Titanium PSUs are 200–240 Vac only.

PSU options at a glance

The master matrix. Every figure here is verbatim from the R760 Installation and Service Manual. Heat dissipation is rated at full load — for cooling planning use the worked example further down, not the nameplate number alone.

Wattage	Class	Mode	Heat at full load	Frequency	Voltage / max current	Hot-plug
700 W	Titanium	Mixed (AC + 240 VDC)	2,625 BTU/hr	50/60 Hz	200–240 Vac at 4.1 A; 240 Vdc at 3.4 A	Yes
800 W	Platinum	Mixed (AC + 240 VDC)	3,000 BTU/hr	50/60 Hz	100–240 Vac at 9.2–4.7 A; 240 Vdc at 3.8 A	Yes
1,100 W	Titanium	Mixed (AC + 240 VDC)	4,100 BTU/hr	50/60 Hz	100–240 Vac at 12–3.6 A; 240 Vdc at 5.2 A. Derates to 1,050 W on 100–120 Vac.	Yes
1,100 W	n/a (DC)	−48 LVDC	4,625 BTU/hr	n/a	−48 to −60 Vdc at 27 A	Yes
1,400 W	Platinum	Mixed (AC + 240 VDC)	5,250 BTU/hr	50/60 Hz	100–240 Vac at 12–8 A; 240 Vdc at 6.6 A. Derates to 1,050 W on 100–120 Vac.	Yes
1,800 W	Titanium	Mixed (AC + 240 VDC)	6,750 BTU/hr	50/60 Hz	200–240 Vac at 10 A; 240 Vdc at 8.2 A	Yes
2,400 W	Platinum	Mixed (AC + 240 VDC)	9,000 BTU/hr	50/60 Hz	100–240 Vac at 16–13.5 A; 240 Vdc at 11.2 A. Derates to 1,400 W on 100–120 Vac.	Yes
2,800 W	Titanium	Mixed (AC + 240 VDC)	10,500 BTU/hr	50/60 Hz	200–240 Vac at 15.6 A; 240 Vdc at 13.6 A	Yes

Maximum PSUs supported (standard R760): 2, hot-pluggable, redundant 1+1 by default. The 3,200 W Titanium PSU that Dell publishes for the 16th-generation 2U platform is not a standard R760 option — it is exclusive to the R760xa GPU server, which we cover further down.

Power cord by PSU output

The PSU module depth and the output wattage together determine the required IEC power cord. Two PSU depths exist for the R760: a 60 mm module (used by 700 W through 1,800 W AC and the 1,100 W LVDC) and an 86 mm deeper module (used by 2,400 W and 2,800 W AC). The cord follows the output rating.

PSU output	Module depth	Required cord (IEC)
700 W / 800 W / 1,100 W / 1,400 W AC; 1,100 W LVDC	Redundant 60 mm	C13
1,800 W AC	Redundant 60 mm	C15
2,400 W AC	Redundant 86 mm	C19
2,800 W AC	Redundant 86 mm	C21

If you are sourcing a refurbished 2,800 W PSU, check the cord designation on the PDP listing carefully — C21 and C22 are not the same connector, and Dell's R760 ISM specifies C21 for the 2,800 W output. We have seen reseller listings (including one we are correcting on our own catalog) that label the cord as C22 when the actual matching cord is C21. If in doubt, match the cord to the PSU module physically, not to the catalog text.

Voltage derating: what happens at 100–120 Vac

This is where most R760 deployments meet their first surprise. Three of the eight standard PSUs derate when fed low-line North American voltage instead of 208/240 Vac high-line, and three others refuse to operate on 120 V at all.

PSU	High-line rating	Low-line (100–120 Vac) rating	Capacity lost
1,100 W Titanium	1,100 W	1,050 W	50 W
1,400 W Platinum	1,400 W	1,050 W	350 W (25%)
2,400 W Platinum	2,400 W	1,400 W	1,000 W (42%)
700 W Titanium	700 W	Does not operate (200–240 Vac only)	—
1,800 W Titanium	1,800 W	Does not operate (200–240 Vac only)	—
2,800 W Titanium	2,800 W	Does not operate (200–240 Vac only)	—

The 2,400 W Platinum is the worst-case offender — a customer in a North American 120 V rack who "specs a 2,400 W PSU" is really specifying a 1,400 W PSU, with all the redundancy and headroom consequences that implies. The 1,400 W Platinum loses 25% on low-line, which is enough to push a borderline configuration into PSU-load-warning territory. The Titanium-class 700 W, 1,800 W, and 2,800 W PSUs are explicitly 200–240 Vac only per the Dell ISM; Dell does not support operation below 200 Vac on these units.

Practical rule: a 120 V branch circuit caps R760 PSU capacity at 1,400 W (via 1,400 W Platinum on low-line, or 1,100 W Titanium derated to 1,050 W). If you need more, you need 208/240 Vac.

Titanium vs Platinum: what the efficiency rating actually buys you

The 80 PLUS efficiency thresholds at 230 V Internal Redundant — the relevant class for Dell server PSUs — break down like this:

Class	10% load	20% load	50% load	100% load
Platinum (230V Internal Redundant)	n/a	90%	94%	91%
Titanium (230V Internal Redundant)	90%	94%	96%	91%

Two real differences matter for an R760 buyer. First, Titanium is certified at 10% load and Platinum is not — meaning Dell guarantees a Titanium PSU still hits 90% efficiency at very light load, which is the operating point most general-purpose servers actually live in for most of their lives. Second, Titanium runs 2 percentage points more efficient at the 50% load sweet spot. Across a 50-server fleet at 24/7 operation, a 2-point efficiency improvement translates to roughly 7 MWh per year of avoided waste heat per server, give or take depending on your average load — at $0.07/kWh blended commercial and counting the cooling offset, the Titanium upgrade typically recovers its capital premium in about 18 months on a heavily-utilized fleet.

The R760 offers Titanium at 700 W, 1,100 W, 1,800 W, and 2,800 W; Platinum at 800 W, 1,400 W, and 2,400 W. If your power-cost economics or sustainability reporting puts a heavy weight on efficiency, target the Titanium tiers. If your priority is sheer wattage at low-line voltage, the Platinum tiers — particularly the 1,400 W and 2,400 W — are the only options that operate down to 100 V.

PSU sizing: worked examples for two real R760 configurations

Dell publishes the Energy Smart Configurator for per-config power budgeting, and you should use it for any production sizing decision. But the methodology is straightforward enough to estimate by hand, and the math is worth showing because the most common sizing mistake we see is buyers under-counting NVMe drives and over-counting CPU TDP.

The worst-case load worksheet:

CPU power      = N_cpu × max TDP                  (e.g., 2 × 350 W = 700 W for dual Xeon Platinum 8480+)
DIMM power     = N_dimm × ~7 W worst-case
Drive power    = N_2.5" NVMe × ~25 W + N_2.5" SAS × ~12 W + N_3.5" SAS × ~18 W
NIC + RAID     = ~50 W (typical: dual 25GbE + PERC + BOSS-N1)
Fan power      = ~120 W worst-case (6 high-perf fans at max RPM)
PSU efficiency = ÷ 0.94 (Platinum) or ÷ 0.96 (Titanium) at 50% load
Headroom       = × 1.20 (20% safety margin)

The per-component figures above are planning estimates; actual draw depends on workload, DIMM density and bank-activation pattern, the specific NVMe drive generation, and fan RPM. Treat these as upper-bound worst-case, not typical.

Heavy configuration: dual Xeon Platinum 8480+, 32× DDR5, 24× NVMe

Component	Watts
2 × 350 W TDP (Sapphire Rapids max TDP)	700
32 × 7 W DDR5 RDIMM worst-case	224
24 × 25 W NVMe SSD worst-case	600
NIC + storage controllers	50
Fans at max	120
DC subtotal	1,694
÷ 0.96 (Titanium 50% load efficiency)	1,765
× 1.20 safety margin	2,118 W wall draw

For this configuration the 2,400 W Platinum is undersized once you account for transients and headroom. Run either the 2,800 W Titanium (which requires 200–240 Vac) or paired 1,800 W Titanium PSUs in symmetric 1+1 redundancy. On a 120 V deployment, the 2,400 W's derate to 1,400 W rules it out entirely — high-line voltage is the only viable path.

Light configuration: dual Xeon Silver 4416+, 8× DIMM, 8× SAS SSD

Component	Watts
2 × 165 W TDP	330
8 × 5 W DIMM low-activity	40
8 × 12 W SAS SSD	96
NIC + controllers	30
Fans at normal RPM	50
DC subtotal	546
÷ 0.94 (Platinum 50% load)	581
× 1.20 safety margin	697 W wall draw

A pair of 800 W Platinum or 1,100 W Titanium PSUs is the right call. Running this on 2,400 W PSUs would land in the 23–30% load band — well below the efficiency peak that sits between 40% and 60% load for Titanium-class supplies. The over-sized PSU costs you efficiency, not just capex.

Sanity-check against measured data: ServeTheHome's R760 review measured a high-performance review unit at over 600 W idle and an estimated ~1 kW at load, on dual 1.4 kW Platinum PSUs. The reviewer's own caveat applies: "A Dell PowerEdge R760 might spend its lifetime in a lower-end configuration running under 200 W. Another might spend its useful life running over 2 kW." Sizing is about the configuration, not the chassis.

BTU/hr for CRAC sizing

The Dell-published BTU/hr column is the heat output of the PSU at full rated load. For cooling planning you almost never need that number directly. Three things to know:

• Watts to BTU/hr conversion: 1 W = 3.412 BTU/hr. Dell's published BTU/hr values match this calculation against the wall-draw wattage at full load (which is higher than the PSU output rating because of inefficiency). For example, a 1,400 W Platinum at ~91% full-load efficiency draws ~1,538 W from the wall, and 1,538 × 3.412 ≈ 5,248 BTU/hr — matching Dell's published 5,250 BTU/hr value almost exactly.
• Only count the actively-drawing PSU. In a 1+1 redundant pair, one PSU is carrying load and the other is either idle or in Hot Spare sleep mode. Cooling load uses 1× BTU/hr, not 2× the nameplate, despite two PSUs being physically present.
• Multiply by actual utilization fraction, not nameplate. Typical steady-state server utilization is 0.30 to 0.60. A 2,400 W Platinum PSU (9,000 BTU/hr at full load) running at 40% utilization in a redundant pair contributes about 3,600 BTU/hr to the rack heat budget. An engineer summing 2 × 9,000 BTU/hr at full load will over-spec CRAC capacity by 4×. An engineer who uses W × 3.412 and ignores efficiency will under-spec by about 10%.

The right number for CRAC planning is Dell-published BTU/hr × actual utilization × the count of PSUs actively drawing. For most R760 fleets that resolves to 0.4 × nameplate BTU/hr × 1 PSU.

Where the 3,200 W Titanium actually lives: the R760xa

If you searched for "R760 3200W Titanium PSU" and found nothing in the Dell configurator, here is why: the 3,200 W Titanium PSU is not a standard R760 option. It is exclusive to the PowerEdge R760xa, Dell's GPU-accelerated 2U variant on the same 16th-generation platform, per the R760xa Installation and Service Manual.

Wattage	Class	Voltage input	Notes
2,400 W	Platinum	100–240 Vac or 240 HVDC	Derates to 1,400 W on low-line 100–120 Vac (same as standard R760)
2,800 W	Titanium	200–240 Vac or 240 HVDC	High-line only
3,200 W	Titanium	277–305 Vac or 336 HVDC	Requires 277 Vac (HVAC) or 336 HVDC infrastructure — not a standard PDU drop

The R760xa is designed for GPU workloads that pull substantially more power than a CPU-only 2U server, which is why its PSU lineup starts at 2,400 W instead of 700 W. The 3,200 W Titanium specifically requires high-voltage AC or HVDC infrastructure — if your datacenter is not delivering 277 Vac to the rack, you cannot use the 3,200 W PSU regardless of which chassis you order it for. Modern hyperscale and AI-focused datacenters are increasingly built on 277/480 Vac three-phase to enable exactly this kind of high-density PSU, but a typical enterprise colo is still on 208 Vac and would not benefit from a 277 Vac PSU.

R760 vs R760xs vs R760xa: the variants diverge on PSU

The 16th-generation 2U Dell PowerEdge has three siblings, and the PSU lineup is materially different between them.

Spec	R760 (standard)	R760xs (entry 2U)	R760xa (GPU 2U)
Workload focus	General-purpose dual-socket	Lower-cost / lower-power	GPU AI/ML/HPC
Smallest PSU	700 W Titanium	600 W Platinum	2,400 W Platinum
Largest PSU	2,800 W Titanium	1,800 W Titanium	3,200 W Titanium (277 Vac / 336 HVDC)
Maximum PSUs	2 (1+1)	2 (1+1)	2 (1+1)
277 Vac / 336 HVDC option	No (240 HVDC only)	Yes (1,400 W Titanium)	Yes (3,200 W Titanium)
Low-line 120 V capable	Limited (1,400 W max via 1,400 W Platinum)	Yes (most options operate 100–240 Vac)	No (high-line only)

The R760xs introduces a 600 W Platinum tier and a 1,400 W Titanium 277 Vac/336 HVDC option that do not exist on the standard R760, but it caps at 1,800 W Titanium. If you are repowering a fleet of R760xs servers with R760 PSUs (or vice versa), check the module form factor and the chassis bay carefully — the SKU coverage does not overlap cleanly across all wattages.

The OEMR XL R760: it is an R760, the PSUs are the R760's

If you have been searching for "OEMR XL R760 PSU specifications" and finding nothing useful, here is the short version: the OEMR XL R760 is Dell's OEM-branded version of the same 16th-generation R760 platform, sold via Dell OEM Solutions to OEMs that white-label Dell hardware (telecom appliance vendors, security appliance vendors, video-encoding-appliance vendors). The hardware is the same R760 chassis with OEM-specific firmware and cosmetic differences.

What carries over from the standard R760:

• The same eight PSU wattage tiers (700 W through 2,800 W mixed mode)
• The same heat dissipation, voltage, and current ratings
• The same hot-plug behavior and 1+1 redundancy support
• The same power cord types per output wattage
• The same low-line voltage derating rules

What can differ between an OEMR XL R760 PSU and a standard R760 PSU is the Dell part number on the unit — Dell OEM Solutions sometimes assigns separate SKUs to physically identical modules so OEM resellers can manage their own part-number tree. If you are replacing a failed PSU in an OEMR XL R760, match the spec (wattage, class, voltage range) and the module depth (60 mm or 86 mm) and you are almost certainly safe. If you are running a strict OEM service contract, source the OEM-specific part number through Dell OEM Solutions or a reseller that handles OEM SKUs.

How the R760 compares to the R750 and R740 for power efficiency

Buyers cross-shopping refurb 14th, 15th, and 16th generation Dell 2U servers typically ask the same question: how much power am I actually saving by going to 16th gen? Principled Technologies' 2023 study answered this with a memtier benchmark against a Redis database running on all three generations.

Comparison	R760 vs R740 (14th gen)	R760 vs R750 (15th gen)
Ops/s	+129.5%	+30.6%
Performance per watt	+24.2%	+3.8%

The plain reading: an R760 doing the same work as a comparable R740 uses roughly 75% of the power for the same output. At $0.07/kWh blended commercial and 24/7 operation, replacing a 600 W average-draw R740 with a 450 W average-draw R760 saves about $92 per server per year in electricity alone, before counting CRAC offset (typically another 0.4 to 0.6× of the electricity savings as avoided cooling cost). Total fleet savings land near $140 per server per year. The exact number depends on your utility rate and your workload — the multiplier does not.

The R760 also accepts 4th-generation Intel Xeon (Sapphire Rapids) and, via BIOS upgrade, 5th-generation Xeon (Emerald Rapids). The PSU sizing math does not change between generations — Sapphire Rapids and Emerald Rapids share the LGA 4677 socket and similar TDP envelope, with the same 350 W TDP ceiling on the top SKUs.

Redundancy and Hot Spare: what iDRAC is actually doing

The R760 supports up to two PSUs in a 1+1 configuration with three operational behaviors, configurable from iDRAC under Power → Configuration.

Mode	What happens
Symmetric 1+1 (default, Hot Spare disabled)	Both PSUs share load 50/50. Full redundancy — either PSU can carry the full load if the other fails.
Hot Spare enabled (1+0)	One PSU carries the full load; the second drops to sleep mode (small current draw only). The sleeping PSU wakes when active load exceeds 50% of single-PSU capacity, and returns to sleep when load falls below 20%. Trades a small amount of failover responsiveness (milliseconds) for efficiency.
2+0 / Non-redundant	Both PSUs active, no formal redundancy guarantee. Rare configuration, usually only seen on intentionally under-spec'd PSU pairs.

Source: Dell PowerEdge Power Settings (KB 000202926) and the iDRAC9 Configuring Power Supply Options guide. The Hot Spare wake/sleep thresholds (50% wake, 20% sleep) come from the iDRAC guide explicitly.

When to enable Hot Spare: if your R760 sits at low average load — say, an idle web tier or a development VM host pulling 200 W against paired 1,400 W PSUs — Hot Spare can consolidate load onto a single PSU at a more efficient operating point on the 80 PLUS curve, saving 15–25 W in waste heat per server. The failover behavior is unchanged in terms of redundancy guarantee; the only trade is that the sleeping PSU takes milliseconds to wake on load increase, which is irrelevant for steady-state workloads but might matter for workloads with sub-millisecond power transient sensitivity (very rare in normal enterprise use).

Gotchas we have run into in the field

1. Mixing input voltage ranges blocks redundancy. Per Dell KB 000198364, "for PSUs with an output rating 1100w and above, a mix of different AC input voltage ranges (low line and high line) is not supported." If one PSU is on a 120 V branch and the other is on a 208 V branch — common after a rack migration where only one circuit got upgraded — iDRAC will flag the low-line unit "incorrectly configured" and you lose redundancy. The fix is to match both PSU inputs to the same voltage range, not to disable the alert.
2. Wattage-mismatched PSUs trigger a critical alert. A 1,400 W in bay A and an 1,800 W in bay B will run, but iDRAC throws a "power supply wattage mismatch" critical alert and you forfeit redundancy. Always match wattage and ideally the Dell part number across both bays. This bites the most when a customer replaces a failed PSU with whatever was on the shelf instead of matching the surviving unit.
3. The 2,400 W Platinum on 120 V is really a 1,400 W PSU. The derating is a 42% capacity loss. We see this most often when a customer sized their PSU on a high-line lab rack and then deployed into a North American 120 V production rack without re-checking the spec.
4. The 700 W, 1,800 W, and 2,800 W Titanium PSUs will not operate on 120 V at all. Dell's ISM lists their input voltage as 200–240 Vac only. Customers occasionally try to test one of these on a 120 V bench outlet and conclude the unit is dead; it is not, the unit is correctly refusing to operate below its rated input range.
5. The cord on the 2,800 W is C21, not C22. Both connectors look similar at a glance, and C22 is the chassis-side variant of the same family (used on PDUs as outlets). The PSU side is C21. Catalog text that says "C22" on a 2,800 W refurb PSU is almost certainly mis-labeled; the physical mating connector is C21 per the Dell ISM. If you are ordering cords, order C20 inlet plug to C21 receptacle to match the PSU.
6. Hot Spare does not improve redundancy. A common misconception: enabling Hot Spare on a 1+1 pair does not give you "extra" redundancy. The mode is purely an efficiency tweak that puts one PSU to sleep at light load and wakes it on demand. If you need more than 1+1 redundancy, you need a chassis that supports more than 2 PSUs (the R760 does not).
7. The 3,200 W PSU is not available for the standard R760. It is an R760xa-only PSU and requires 277 Vac infrastructure. Searches and forum threads frequently conflate the two chassis; the configurator does not lie.
8. Refurb PSU SKUs cross between R750 and R760. The 2,800 W Titanium PSU (Dell P56GH) is documented for both R750xs and R760, and the same physical unit works in both chassis. This is a legitimate cross-platform sourcing path — a refurb PSU pulled from an R750 will work in an R760 provided the part number and module depth match.

Frequently asked questions

How many PSUs does the Dell PowerEdge R760 support?

The standard R760 supports up to two hot-plug PSUs in a 1+1 redundant configuration. Both must be the same wattage and same input voltage type — Dell does not support mixed-wattage or mixed-voltage configurations and will flag any mismatch as a critical alert in iDRAC. Source: Dell R760 Installation and Service Manual.

What is the heat dissipation of each R760 PSU?

Heat dissipation at maximum rated load is 2,625 BTU/hr (700 W), 3,000 BTU/hr (800 W), 4,100 BTU/hr (1,100 W Titanium), 4,625 BTU/hr (1,100 W LVDC), 5,250 BTU/hr (1,400 W), 6,750 BTU/hr (1,800 W), 9,000 BTU/hr (2,400 W), and 10,500 BTU/hr (2,800 W). For CRAC planning, multiply by actual utilization (typically 0.30 to 0.60) and count only the actively-drawing PSU in a 1+1 pair — not the nameplate sum.

Does the PowerEdge R760 support a 3,200 W power supply?

No — the standard R760 does not. The 3,200 W Titanium PSU is exclusive to the R760xa GPU server and requires 277 Vac or 336 HVDC input. The standard R760 maxes out at the 2,800 W Titanium, which runs on 200–240 Vac. If you need 3,200 W per PSU and have 277 Vac infrastructure, the right chassis is the R760xa, not the standard R760.

What happens to R760 PSU output at low-line 100–120 Vac?

Three PSUs derate: the 1,100 W Titanium drops to 1,050 W, the 1,400 W Platinum drops to 1,050 W (25% loss), and the 2,400 W Platinum drops to 1,400 W (42% loss). The 700 W, 1,800 W, and 2,800 W Titanium PSUs are 200–240 Vac only and will not operate on 120 V. A 120 V deployment effectively caps R760 PSU capacity at 1,400 W via the 1,400 W Platinum on low-line.

What is the difference between Titanium and Platinum efficiency PSUs on the R760?

At 230 V Internal Redundant operation, Titanium delivers 90/94/96/91% efficiency at 10/20/50/100% load; Platinum delivers 90/94/91% at 20/50/100% load (Platinum is not certified at 10% load). Titanium runs 1–2 percentage points more efficient at typical 30–60% load. The R760 offers Titanium at 700 W, 1,100 W, 1,800 W, and 2,800 W; Platinum at 800 W, 1,400 W, and 2,400 W.

What power cord do I need for each R760 PSU?

700 W, 800 W, 1,100 W AC, 1,400 W, and 1,100 W LVDC PSUs (60 mm module depth) use C13 cords. The 1,800 W AC (60 mm) uses C15. The 2,400 W AC (86 mm) uses C19. The 2,800 W AC (86 mm) uses C21. The 60 mm vs 86 mm distinction is PSU module depth and determines the chassis bay.

Is the OEMR XL R760 PSU the same as the standard R760 PSU?

Yes, with one caveat: the wattage tiers, heat dissipation, voltage ranges, current ratings, and power cord types are identical because the OEMR XL R760 uses the same 16th-generation R760 chassis. Dell OEM Solutions sometimes assigns separate part numbers to physically identical modules for OEM service-contract tracking. If you are matching by specification (wattage, class, voltage range, module depth), an OEMR XL R760 PSU and a standard R760 PSU are interchangeable; if you are matching by strict OEM service contract, source the OEM-specific part number.

Can I mix PSUs of different wattages in the R760?

No. Dell flags any wattage mismatch as a critical alert in iDRAC and removes redundancy. Both PSU bays must use the same wattage and ideally the same Dell part number. This applies even when the chassis will physically accept a mismatched unit — running with mismatched PSUs is unsupported.

Can I use 5th-generation (Emerald Rapids) Xeon processors with the R760?

Yes — Dell supports Emerald Rapids on the R760 via a BIOS upgrade. Emerald Rapids and Sapphire Rapids share the LGA 4677 socket and similar TDP envelope (350 W ceiling on top SKUs), so the PSU sizing math does not change between generations.

How does the R760 compare to the R750 and R740 for energy efficiency?

Per Principled Technologies' 2023 study, the R760 delivers 129.5% more operations per second than the R740 with 24.2% better performance per watt, and 30.6% more Ops/s than the R750 with 3.8% better performance per watt. An R760 doing the same work as a comparable R740 uses roughly 75% of the power for the same output — approximately $140 per server per year saved on a 24/7 deployment at $0.07/kWh after CRAC offset.
