What processors does the Dell PowerEdge XE9685L use?
Two AMD EPYC 9005 processors chosen from five models: 9965 (192 cores), 9755 (128), 9655 (96), 9575F (64) and 9455 (48). Default TDPs run from 300 W to 500 W, all cooled by cold plates, and each socket provides up to 128 PCIe 5.0 lanes.
Which GPUs does the XE9685L support?
Only one board: eight NVIDIA HGX B200 GPUs with 180 GB each at 1000 W on SXM6, fully connected by NVLink. The GPUs and the NVLink switches sit under cold plates on a sled in the lower half of the chassis.
How much memory does the XE9685L support?
Up to 3 TB in 24 DDR5 RDIMM slots at up to 6400 MT/s, one DIMM per channel across twelve channels per processor. Because the B200 board needs every slot populated, the module size alone sets the total: 1.5 TB with 64 GB parts, 2.3 TB with 96 GB and 3 TB with 128 GB.
Does the XE9685L need liquid cooling?
Yes, it is direct liquid-cooled: coolant tubes for the processors and for the GPU sled leave the rear, and twelve fans (six per layer) run alongside the cold plates. Dell’s spec sheet says the liquid loop captures 70% of the heat, and its acoustic figures leave out the CDU.
How many PCIe slots does the XE9685L have?
Twelve x16 PCIe Gen5 full-height, half-length slots, 31 to 42, behind four PCIe switches. Dell allows up to twelve 400G N400 cards, 400G DPUs, Broadcom 200G or Mellanox 100G NICs, and slots 33 and 39 take DPUs above 75 W. One x8 OCP 3.0 slot and a two-port 1 GbE LOM are extra.
What power supplies does the XE9685L use?
Six 3000 W Titanium supplies, listed as post-launch, in 5+1 or 3+3 redundancy. Each delivers 3000 W from a 209.1–240 V AC or 240 V DC feed and 2800 W on 200–209 V AC, uses a C21 cord, and must not be mixed with another vendor’s units.
How big and heavy is the XE9685L?
A 4U chassis 174.3 mm tall and 1037.57 mm deep including the bezel. Dell’s guide gives 94.6 kg fully populated while its spec sheet says 91.63 kg; either way Dell recommends a server lift and installation below 24U in the rack.
How does the XE9685L differ from the XE9680L?
Both are 4U, liquid-cooled and have twelve PCIe slots and eight NVMe bays. The XE9685L is AMD-hosted, taking EPYC 9005 parts of 48 to 192 cores, with 24 DIMMs at 6400 MT/s and a 3 TB ceiling, and supports only B200. Its Intel sibling runs 5th Gen Xeon with eight more DIMM slots (4 TB maximum) and can be ordered with H200 as well as B200.
Which operating systems does the XE9685L support?
Canonical Ubuntu Server LTS in every Dell document. The guide’s operating-system chapter also lists Red Hat Enterprise Linux, although its features table and the spec sheet name Ubuntu alone, so we confirm the RHEL release with Dell before ordering.
Is the Dell PowerEdge XE9685L end of life?
No model-wide end-of-sale or end-of-support date appears in Dell’s June 2026 guide for the XE9685L. Use our server end-of-life checker, which adds Dell’s dates when they are announced.
