The R760xa is Dell’s two-socket 2U built around accelerators. GPU risers flank a small central drive cage at the front and hold four double-wide cards of up to 400 W or eight single-wide cards, and four rear slots lift the single-wide count to twelve. Below are the processors, memory rules, slot map, power and thermal limits in Dell’s guide, and what the GPU-first layout gives up.

Our read of Dell’s documentation: where the R760xa is strong, and the limits worth knowing before you spec one.
Strengths
+Twelve PCIe Gen5 slot positions in 2U: eight single-wide or four double-wide at the front, plus four full-height x16 slots at the rear for fabric or storage adapters.
+Double-wide cards are rated to 400 W, up from 300 W on the R750xa, and Dell’s matrix clears front GPUs of up to 350 W at 35°C with every listed processor except the two liquid-only SKUs.
+Both 4th and 5th Gen Xeon Scalable are supported — 30 SKUs, up to 64 cores each — behind 32 DDR5 slots.
+A 3200 W Titanium supply for 277 V AC or 336 V DC sits alongside the 2400 W and 2800 W units, for sites with high-voltage distribution.
+Optional direct liquid cooling for the processors, which is how Dell supports the 350 W 8470Q and 6458Q in this chassis.
Watch-outs
!Storage is deliberately minimal: eight 2.5-inch or six E3.S bays at most, all at the front, with no 3.5-inch or rear drive option.
!At 946.73 mm deep with the bezel it is 38.09 mm longer than the R750xa, so check rack depth and rear cable clearance.
!Only 86 mm supplies are offered, and just the 2400 W unit runs at 100–120 V, where it falls to 1400 W; the 2800 W and 3200 W units have no low-line rating.
!With a front GPU above 350 W and processors over 225 W the inlet limit drops to 30°C; in ASHRAE A3 and A4 rooms rear GPUs are out and only the A2 and Intel ATS-M75 may use the front slots.
!Every riser configuration in Dell’s table draws on both processors: R1V and the right-hand front riser belong to processor 1, R4T and the left-hand front riser to processor 2.

The 350 W Platinum 8470Q and Gold 6458Q are the only SKUs Dell will not air-cool here; both need the processor liquid-cooling option.
Every other listed processor, up to 350 W, is supported at 35°C inlet with front GPUs of 350 W or less.
5th Gen parts run UPI at 20 GT/s apart from the Silver 4514Y, 4510 and 4509Y, which stay at 16 GT/s like the whole 4th Gen list.
Turbo frequencies are not published in the guide’s tables — each row simply reads “Turbo”.
03 — Memory
32 DIMM slots, 16 per processor
Thirty-two DDR5 RDIMM slots, sixteen per processor. With 4th Gen Xeon a single DIMM per channel runs at up to 4800 MT/s; 5th Gen can use 6400- or 5600-rated modules there. A second DIMM in the channel caps every configuration at 4400 MT/s.

The 8 TB ceiling is 32 × 256 GB, and that module is an eight-rank part rated at 4800 MT/s. The 6400/5600 MT/s modules intended for 5th Gen stop at 128 GB, or 4 TB across 32 slots.
A module’s rating is not the speed you get: Dell’s processor tables give each SKU its own memory speed, from 4000 to 4800 MT/s across the 4th Gen list and from 4400 MT/s (Silver) to 5600 MT/s (Platinum 8500 series) across the 5th Gen list.
96 GB DIMMs carry GPU-linked limits: Dell’s note gives two per channel up to 30°C with GPUs of 250 W or less, and one per channel up to 35°C with GPUs above 250 W.
Keep DIMMs below 96 GB for A3 or A4 rooms, where larger modules are unsupported; the quad-rank 128 GB part has also reached end of life.
04 — Storage
5 drive-bay layouts, up to 8 bays
Five layouts, all in the middle of the front panel between the GPU bays: six or eight 2.5-inch drives, or six EDSFF E3.S. Dell’s capacity figures are 122.88 TB across eight 2.5-inch drives and 46.08 TB across six E3.S drives. Bulk data belongs on external storage — Dell lists 12 Gb MD-series JBODs, a NAS software stack and USB tape.

The universal layout has eight SAS/SATA bays, two of which also take NVMe; SAS/SATA drives get hardware RAID while those NVMe drives are direct-attached.
Dell’s drive table for this model lists SATA and SAS SSDs only, from 480 GB to 15.36 TB — no hard-disk drives appear in it.
BOSS-N1 keeps the operating system off the front bays; it is not supported in ASHRAE A4 conditions.

GPUs, PCIe and networking
This is the reason to buy an R760xa. The GPUs mount at the front on two risers: RF1A and RF2A provide four full-length double-wide x16 slots, or RF1B and RF2B provide eight single-wide x8 slots. Four more full-height x16 slots at the rear accept single-wide cards, which is how the count reaches twelve. Four double-wide cards at up to 400 W, or twelve single-wide at 75 W. Dell names the NVIDIA A100, A30 and A2 and the Intel ATS-M75.

AC277 VAC / HVDC
Low-line 100–120 V AC works only with the 2400 W supply, rated 1400 W there; the 2800 W unit needs 200–240 V and the 3200 W unit 277 V AC or 336 V DC.
Cords: C19 for 2400 W, C21 for 2800 W (or C19 with a C20-to-C21 jumper) and APP 2006G1 for 3200 W.
Dell lists heat dissipation of 9000, 10,500 and 12,000 BTU/hr for the three supplies respectively.
Supplies must match: a mismatched pair at POST enables only the larger unit, and a mismatched supply added later stays disabled.
ASHRAE A3 and A4 operation requires both supplies.

Four double-wide NVIDIA A100s in the front risers — the card and 300 W rating Dell uses in its Configuration A acoustic test — with 48-core 5th Gen processors, a terabyte of DDR5 and 100GbE on the OCP slot, leaving the rear x16 slots free for fabric adapters.
2 × Xeon Platinum 8568Y+ — 48 cores @ 2.3 GHz, 350 W each
4 × NVIDIA A100, double-wide, in the front GPU risers
These are 350 W processors, so a front GPU above 350 W would cap inlet air at 30°C; at the A100’s 300 W Dell’s matrix allows 35°C. Keep it in an ASHRAE A2 room: A3 and A4 exclude processors above 225 W and 185 W respectively and accept only the A2 and ATS-M75 as GPUs.
Every slot filled with single-wide NVIDIA A2s — eight in the front x8 risers and four at the rear — for dense virtual desktops, one of the workloads Dell lists for this model. Sixteen 128 GB modules give 2 TB, and networking moves to the OCP bay because no PCIe slot is left.
2 × Xeon Gold 6548Y+ — 32 cores @ 2.5 GHz, 250 W each
Dell’s A3 rules (5–40°C inlet) allow only the NVIDIA A2 and Intel ATS-M75 in the front slots, processors of 225 W or less and DIMMs smaller than 96 GB. This build stays inside them: eight front ATS-M75 cards, 24-core 225 W processors and 64 GB modules.

A3 also excludes peripheral cards over 25 W or not qualified by Dell, calls for 85°C-rated active optical cables and warns that performance may drop if a supply fails. Rear-slot GPUs are not supported in A3.
The 32-core Gold 6458Q runs at a 3.1 GHz base but is supported only with processor liquid cooling. Paired with four NVIDIA A30s and six E3.S Gen5 drives for scene data, it targets render farms and digital twins, both on Dell’s workload list for the R760xa.

12 — FAQ
R760xa questions, answered from the documentation
How many GPUs does the Dell PowerEdge R760xa support?
Up to four double-wide accelerators at up to 400 W each, or up to twelve single-wide 75 W cards. Double-wide cards use the RF1A and RF2A front risers; single-wide builds use eight front x8 slots on RF1B and RF2B plus the four rear x16 slots. Dell’s guide names the NVIDIA A100, A30 and A2 and the Intel ATS-M75.
What is the maximum memory of the R760xa?
It has 32 DDR5 RDIMM slots, 16 per processor. Filled with 256 GB modules that is 8 TB, and the 256 GB part appears in Dell’s table solely as an eight-rank RDIMM rated at 4800 MT/s. Using the faster 6400/5600 MT/s modules for 5th Gen Xeon, the largest is 128 GB, so 4 TB.
Which processors fit the R760xa?
Thirty: 19 4th Gen Xeon Scalable SKUs of up to 56 cores and 11 5th Gen SKUs of up to 64 cores, from 125 W to 350 W. Dell’s comparison table lists it with two processors, and every riser layout uses both. The Platinum 8470Q and Gold 6458Q need direct liquid cooling; all the others are supported on air at 35°C with front GPUs of 350 W or less.
How many drives does the R760xa hold?
Eight 2.5-inch drives or six EDSFF E3.S Gen5 NVMe drives, all at the front, with no rear bays. Dell quotes up to 122.88 TB for the eight-bay 2.5-inch layouts and 46.08 TB for the E3.S layout. The operating system can sit on a separate BOSS-N1 boot device.
What PCIe slots does the R760xa have?
At most twelve PCIe Gen5 slot positions: four full-height x16 slots at the rear on risers R1V and R4T, plus either four double-wide x16 or eight single-wide x8 full-length slots at the front. Each processor supplies 80 PCIe 5.0 lanes. Alongside them are an OCP NIC 3.0 slot running PCIe Gen4 at x8 (x16 when the optional cable is fitted) and an optional 2 × 1GbE LOM.
Which power supplies does the R760xa use?
Two 86 mm hot-plug supplies in 1+1: 2400 W Platinum, 2800 W Titanium, or 3200 W Titanium for 277 V AC and 336 V DC. Only the 2400 W unit runs at 100–120 V, where it delivers 1400 W. Dell gives peak ratings of 4080 W, 4760 W and 5440 W respectively at high line.
How big and heavy is the R760xa?
Height is 86.8 mm (2U) and width 482 mm; depth is 946.73 mm including the bezel or 932.89 mm without it. Dell quotes a maximum of 27.5 kg with every drive bay filled, and 25.1 kg with no drives or power supplies fitted.
How does the R760xa differ from the R760?
Both are two-socket 2U servers for 4th and 5th Gen Xeon with 32 DDR5 slots. The R760 is the storage-rich generalist, with up to 28 drive bays and room for two double-wide 350 W or six single-wide GPUs. The R760xa gives up most of the bays for four double-wide 400 W or twelve single-wide cards, and is 946.73 mm deep with the bezel against the R760’s 772.13 mm.
What changed from the R750xa?
DDR5 replaces DDR4 and Optane PMem, processors move to 4th and 5th Gen Xeon Scalable, and the GPU ceiling rises from four 300 W double-wide or eight 150 W single-wide cards to four 400 W or twelve 75 W cards. E3.S Gen5 drives and a 3200 W supply are added, and the chassis is 38.09 mm deeper.
Is the Dell PowerEdge R760xa end of life?
Not according to the June 2026 revision (A06) of Dell’s technical guide, which gives no end-of-sale or end-of-service date for the R760xa. Its services appendix does list Post Standard Support, a way to add up to five further years of hardware coverage once the initial seven years of ProSupport run out. Our end-of-life checker will carry dates when Dell publishes them.
