Dell PowerEdge R760xa Specifications
The R760xa is Dell's 16th Generation (16G) purpose-built GPU server — a dual-socket 2U platform whose front bays are given over to accelerators rather than drives, which is what lets it carry four 400 W double-width cards in 2U.

The R760xa's defining constraint is power delivery, not compute. Its PSU ladder starts at 2,400 W — where the standard R760 starts at 700 W — and the top 3,200 W Titanium unit is exclusive to this model. That unit requires 277 VAC or 336 HVDC input, which is a facility decision, not a configuration one: it will not run from an ordinary 208 V rack PDU. The 2,400 W Platinum unit is the only one that accepts 100–240 VAC, and it derates to 1,400 W on 100–120 V low line.
R760xa Chassis Options at Enterasource
Dell builds the R760xa in five internal storage configurations. Because the front of the chassis is shared with the GPU risers, drive count is deliberately modest — this is an accelerator platform with boot and scratch storage, not a storage server.
| Chassis | Front Bays | Controller Path | Max Raw Capacity |
|---|---|---|---|
| 8x2.5" SAS/SATA | 8x 2.5" SAS/SATA | PERC hardware RAID | 122.88 TB |
| 8x2.5" SAS/SATA + 2 Universal | 8x 2.5" SAS/SATA with two universal slots | SAS/SATA hardware RAID + NVMe direct | 122.88 TB |
| 8x2.5" NVMe RAID | 8x 2.5" NVMe | NVMe hardware RAID | 122.88 TB |
| 6x2.5" NVMe | 6x 2.5" NVMe | Direct attached (S160) | 92.16 TB |
| 6x E3.S Gen5 NVMe | 6x E3.S Gen5 NVMe | Direct attached (S160) | 46.08 TB |
The GPU riser choice is separate from the drive choice. Dell offers two front riser layouts: four x16 full-height, full-length double-width slots, or eight x8 full-height, full-length single-width slots — both alongside four x16 half-length rear slots. Tell us the accelerators you intend to run and we will match the riser set to them.

Dell R760xa vs R760 — When the GPU Chassis Is Required
Both are 16th Generation dual-socket 2U servers on the same processor and memory platform. The difference is what the chassis is built to carry.
| Feature | R760xa | R760 |
|---|---|---|
| Double-width GPUs | Up to 4 (400 W) | Up to 2, via GPU enablement kit |
| Single-width GPUs | Up to 12 | Up to 6 |
| GPU risers | Purpose-built, front-facing, standard | Optional enablement kit |
| Front drive bays | Up to 8x 2.5" or 6x E3.S | Up to 24x 2.5" or 12x 3.5" |
| Smallest PSU | 2400 W Platinum | 700 W Titanium |
| Largest PSU | 3200 W Titanium (277 VAC / 336 HVDC) | 2800 W Titanium |
| Direct Liquid Cooling | Optional | Optional |
| Memory | Same — 32x DDR5 RDIMM, 8 TB | Same |
| Processors | Same — 4th/5th Gen Xeon Scalable | Same |
Choose the R760xa when accelerator density is the requirement — four double-width cards, twelve single-width cards, or any deployment where sustained GPU TDP matters more than drive count. Choose the R760 when you need storage capacity and only one or two accelerators; its enablement kit covers light GPU use without the 2,400 W power floor.
Planning Power and Cooling for the R760xa
Four 400 W accelerators plus two 350 W processors is a different facility problem from a general-purpose 2U server, and it is usually where R760xa projects stall.
Input voltage decides your PSU. Only the 2,400 W Platinum unit runs on 100–240 VAC, and it derates to 1,400 W below 120 V. The 2,800 W Titanium requires 200–240 VAC. The 3,200 W Titanium requires 277 VAC or 336 HVDC and uses an APP 2006G1 connector rather than a C13/C19 cord — if your racks are fed from a standard PDU, that unit is not available to you regardless of budget.
Heat rejection scales with the PSU. Dell rates the three supplies at 9,000, 10,500, and 12,000 BTU/hr respectively. Size CRAC capacity from the supply you actually order, not from the server's idle draw.
Ambient temperature caps GPU choice. The R760xa is rated for 10–35°C continuous operation under ASHRAE A2, but Dell restricts the hottest combinations further — accelerators above 350 W paired with processors above 225 W require a maximum 30°C inlet. Direct Liquid Cooling is available for the processors and is a rack-level solution: it needs manifolds and a cooling distribution unit, not just a server option.
Fan redundancy is built in. Up to six hot-swap fans provide N+1 redundancy, so a single fan failure does not take the node down — which matters when a node holds four accelerators.
Frequently Asked Questions
How many GPUs does the Dell R760xa support?
Up to four double-width PCIe Gen5 x16 accelerators rated to 400 W each, or up to twelve single-width 75 W PCIe Gen5 x8 accelerators. If single-width cards are installed in x16 slots, the maximum is eight. Dell supports PCIe GPU adapters from NVIDIA, AMD, and Intel on this platform.
What is the difference between the Dell R760 and R760xa?
They share the same 16th Generation platform — 4th and 5th Generation Intel Xeon Scalable processors, 32 DDR5 RDIMM slots, PCIe Gen 5, iDRAC9. The R760xa is the purpose-built accelerator variant: its front bays carry GPU risers rather than drives, so it takes four double-width cards as standard where the R760 takes two with an enablement kit. The trade is storage — up to 8 front drives on the R760xa versus up to 24 on the R760 — and power, since the R760xa's smallest supply is 2,400 W.
What generation is the Dell R760xa?
The Dell PowerEdge R760xa is a 16th Generation (16G) dual-socket server, regulatory model E102S Series. The 15th Generation predecessor is the R750xa, which takes four double-width accelerators at 300 W and up to eight single-width.
What power supplies does the R760xa use?
Three options, all hot-swap and 1+1 redundant: 2,400 W Platinum (100–240 VAC or 240 HVDC, derating to 1,400 W on 100–120 V low line), 2,800 W Titanium (200–240 VAC or 240 HVDC), and 3,200 W Titanium (277 VAC or 336 HVDC). The 3,200 W unit is exclusive to the R760xa within the 16G 2U family and requires high-voltage facility power.
How much memory does the Dell R760xa support?
32 DDR5 RDIMM slots supporting up to 8 TB total, or 4 TB per processor. The platform is registered ECC RDIMM only — LRDIMM is not supported. Speeds reach 4800 MT/s at one DIMM per channel with 4th Generation processors and 5600 MT/s at one DIMM per channel with 5th Generation processors; both drop to 4400 MT/s at two DIMMs per channel.
What storage configurations does the R760xa offer?
Five: 8x 2.5-inch SAS/SATA; 8x 2.5-inch SAS/SATA with two universal slots combining SAS/SATA hardware RAID and direct-attached NVMe; 8x 2.5-inch NVMe with hardware RAID; 6x 2.5-inch NVMe direct attached; and 6x E3.S Gen5 NVMe direct attached. Boot is handled separately by a BOSS-N1 card with two M.2 NVMe SSDs in hardware RAID, so the front bays stay free for data.
Can the R760xa be liquid cooled?
Yes, optionally, and for the processors only. Dell's Direct Liquid Cooling for this platform is a rack-level solution — it requires rack manifolds and a cooling distribution unit to operate, so it is a facility decision made alongside the server. Air cooling with up to six hot-swap fans and N+1 redundancy is the standard configuration.
