Dell PowerEdge XE9780Specifications, configurations & comparisons

The XE9780 is Dell’s 10U air-cooled training server: two Xeon 6 processors driving an eight-GPU NVIDIA HGX B300 or B200 board, fed by twelve 3200 W supplies and cooled by a wall of fans instead of a liquid loop. Below is what Dell’s technical guide documents for it, including how the choice of GPU board changes the slots, networking and operating systems you get.

01 — Overview

The XE9780 at a glance

Our read of Dell’s documentation: where the XE9780 is strong, and the limits worth knowing before you spec one.

Strengths

A choice of two eight-GPU HGX boards: B300 NVL8 with 270 GB per GPU at 1100 W, or B200 with 180 GB at 1000 W, all eight GPUs joined by NVLink.
Air is the only cooling option in Dell’s feature table — 15 hot-swap GPU fans and five CPU fans, rated across a 10–35°C inlet range.
With B300, eight OSFP ports from embedded ConnectX-8 NICs are built in, and the four remaining PCIe slots take NICs or DPUs.
With B200, twelve front Gen5 x16 slots accept up to twelve ConnectX-7 NDR 400G InfiniBand or 200 GbE cards.
All I/O and expansion faces the front — OCP card, iDRAC ports, BOSS-N1, drives and PCIe cards; the rear carries only fans and supplies.

Watch-outs

Ten rack units, 439.5 mm tall and up to 163.20 kg fully populated: Dell requires a lift, and supports up to four per IR5048 or IR5052 rack.
It is 1044.7 mm deep with the bezel, and Dell warns that the length can foul rear-mounted PDUs or the rear rack door.
Choosing B300 cuts the PCIe complement from twelve slots to four — numbers 3, 6, 9 and 12, each rated to 150 W.
The twelve supplies deliver 3200 W only on 216.1–240 V AC or 240 V DC, drop to 2900 W at 200–216 V, and have no low-line rating.
Operating-system support is narrow: Ubuntu Server LTS for either board, Red Hat Enterprise Linux only with B300, and OpenManage Enterprise and its plug-ins are listed as post-RTS.

02 — Processors

4 supported processors, mapped

Dell qualifies only four Xeon 6 P-core processors here, from the 48-core 6747P at 2.7 GHz to the 86-core 6787P at 2.0 GHz, all rated at 330 W or 350 W. Dell’s thermal matrix clears all four with both the B300 and the B200 board.

Every listed processor uses a 2U extended heat sink with standard fans in both GPU configurations — there are no fan tiers to choose.
Dell’s processor table gives each part 24 GT/s UPI, 6400 MT/s memory and 4 TB of memory capacity, and marks turbo only as present.
The guide’s generic processor-family figures — up to 144 cores in the processor chapter and a 500 W maximum TDP in Table 1 — exceed all four parts cleared for this chassis.
The socket is Intel’s 4710-pin package, with up to four UPI 2.0 links per processor.

03 — Memory

32 DIMM slots, 16 per processor

The 32 RDIMM slots split sixteen to a processor over eight DDR5 channels and take 64, 96 or 128 GB modules at 1.1 V. The unusual rule here is a floor, not a ceiling: Dell’s guide relays an NVIDIA design-guide requirement that an eight-GPU system hold more than 1 TB of memory in total with B200, and more than 2 TB with B300.

by DIMM size

Operating speed

per Dell memory tables

Processor	1 DIMM / channel	2 DIMMs / channel
Xeon 6 P-core (all four listed SKUs)	6400 MT/s	5200 MT/s

The 4 TB maximum is 32 × 128 GB. Dell says it would rise to 8 TB if 256 GB DIMMs were supported after launch, but lists no such module.
For B300, 16 × 128 GB gives exactly 2 TB and misses the more-than-2 TB rule; the balanced fills that clear it are 32 × 96 GB (3 TB) and 32 × 128 GB (4 TB), both at two DIMMs per channel and 5200 MT/s.
For B200, 16 × 96 GB (1.5 TB) or 16 × 128 GB (2 TB) clears the 1 TB rule at one DIMM per channel and keeps 6400 MT/s.
Dell requires DIMM blanks whenever fewer than 16 modules are fitted, and notes that the top speed depends on processor and population.

04 — Storage

2 drive-bay layouts, up to 16 bays

Storage is deliberately plain: sixteen E3.S Gen5 NVMe bays attached directly from the PSB at x4 Gen5, or ten 2.5-inch U.2 Gen5 NVMe bays listed as post-RTS. There is no PERC, no SAS or SATA and no hard-disk option; Dell’s S160 software RAID is the only array layer for the data drives.

Dell’s configuration matrix calls the E3.S layout C01 and the U.2 layout C02; both need two processors and fit no PERC.
Boot is separate from the data bays: a BOSS-N1 DC-MHS module with two M.2 SSDs sits in the front I/O area.
The guide gives no drive capacity table for this model, so raw capacity depends on the E3.S drives quoted.
Empty drive, M.2 and OCP positions need blanks, and every empty PCIe slot needs a GYP32 blank.

GPUs, PCIe and networking

The GPU complex is an eight-way NVIDIA HGX board on its own sled, fitted in internal slots 21–28, with an NVSwitch cover across its centre and the rear fan wall cooling it. Dell pairs each board with a different base board — B200 with the PSBB, B300 with the PCIe Switch Retimer Base Board (PSRBB) — and the two configurations expose different front slots. One of two mutually exclusive boards: 8 × HGX B300 NVL8 (270 GB, 1100 W) or 8 × HGX B200 (180 GB, 1000 W), fully interconnected with NVLink. Table 1 lists both as SXM6; Table 2 prints SXM7 for B300. B300 adds eight embedded ConnectX-8 OSFP ports.

All PCIe is Gen5 x16 full-height, half-length and sits on the front face, alongside a single OCP 3.0 card. Slots 2–7 hang off CPU 2 and slots 8–13 off CPU 1 in Dell’s slot matrix, and the usable set depends on the GPU board.

In B200 builds Dell’s fill order for network cards starts at slots 4, 8, 7 and 11 and finishes at 3 and 12; in B300 builds NICs and DPUs use slots 6, 9, 3 and 12, at most four cards.
NVIDIA DPUs B3220 and B3240 appear in Dell’s thermal table only for the B300 configuration.
The OCP bay is Gen5 x8 in Dell’s Table 1 but Gen4 x8 (35 W, 200 GbE maximum) in its OCP 3.0 feature list (Table 11). Only the Broadcom and NVIDIA dual-port 25 GbE cards were available at RTS.
Table 2 lists the embedded NIC as N/A, although the appendix’s NIC section opens with a generic line about two 10/100/1000 Mbps LOM ports; its port table lists only the two front iDRAC RJ45 ports and the OCP card. iDRAC Direct over USB Type-C is the other management route.

06 — Power & cooling

1 power supply, 3,200 W

Twelve 3200 W Titanium supplies in a 73.5 mm × 185 mm form factor, run as 6+6 for full redundancy or split across A and B grids. Each is one multi-rated unit: 3200 W on 216.1–240 V AC or 240 V DC, 2900 W on 200–216 V AC, and 5280 W peak on high line.

Each supply takes a C19 lead into a C20 inlet and outputs 54 V; Dell’s HPM-sled figure also labels a power interposer board, a power distribution board and busbar cables.
Dell rates the supply’s efficiency at 90% (10% load), 94% (20%), 96% (50%) and 91% (full load); that efficiency table (Table 31) gives the form factor as 86 mm, against 73.5 mm elsewhere in the guide.
Each supply dissipates up to 11,850 BTU/hr at its 3200 W rating, or 10,750 BTU/hr in the 2900 W mode.
There is no low-line or −48 V DC rating, and the XE9780 supports neither a user power cap nor Sound Cap; Dell points to its EIPT tool for sizing.

The XE9780 family side by side

The XE9780 is Dell’s air-cooled Xeon 6 host for an eight-GPU HGX B300 or B200 board. The XE9785 keeps the 10U air-cooled HPM-plus-GPU-sled design with AMD EPYC 9005 processors and a choice of AMD Instinct MI355X or HGX B300; the XE9780L puts the same four processors and both HGX boards into a liquid-cooled 3 OU node for IR7044/IR7050 racks. The 6U XE9680 is the predecessor.

11 — FAQ

XE9780 questions, answered from the documentation

Which GPUs does the Dell PowerEdge XE9780 support?

One eight-GPU NVIDIA HGX board: either HGX B300 NVL8 with 270 GB per GPU at 1100 W, or HGX B200, whose GPUs carry 180 GB each and draw 1000 W, all fully linked by NVLink. Dell’s overview lists both as SXM6, while its Table 2 prints SXM7 for B300. The two are separate configurations, each with its own PCIe base board, so the GPU choice also fixes the slot layout.

What is the maximum memory of the XE9780?

Four terabytes, from 32 × 128 GB DDR5 RDIMMs at 5200 MT/s. Dell says 8 TB would follow if 256 GB modules were supported after launch. There is also a minimum: more than 1 TB with B200 and more than 2 TB with B300, per NVIDIA’s design guide.

How many drive bays does the XE9780 have?

Sixteen E3.S Gen5 NVMe bays, or ten 2.5-inch U.2 Gen5 NVMe bays listed as post-RTS. Drives attach directly over PCIe with S160 software RAID; there is no PERC, SAS or SATA option. Boot uses a separate BOSS-N1 module with two M.2 SSDs.

How many PCIe slots does the XE9780 have?

Twelve Gen5 x16 full-height, half-length slots with the B200 board (eight at 75 W and four at up to 150 W), but only four (slots 3, 6, 9 and 12) with B300, which adds eight embedded ConnectX-8 OSFP ports instead. A single OCP 3.0 card and the BOSS-N1 module are extra to those slots.

What power does the XE9780 need?

Twelve 3200 W Titanium supplies on C19 leads, in 6+6 redundancy or split across A and B grids. Each delivers 3200 W at 216.1–240 V AC or 240 V DC and 2900 W at 200–216 V AC, with no low-line rating. The server does not support a user power cap.

How big and heavy is the PowerEdge XE9780?

It is a 10U chassis, 439.5 mm high, 448.0 mm wide and 1044.7 mm deep with the bezel (1023 mm without). Fully populated it weighs 163.20 kg with B200 or 159.65 kg with B300, so a lift is required, and Dell supports up to four in an IR5048 or IR5052 rack.

Does the XE9780 need liquid cooling?

No. Air is the only cooling option Dell lists: 15 hot-swap GPU fans at the rear and five cold-swap CPU fans, across a 10–35°C inlet range, with no ASHRAE A3 or A4 configurations. The liquid-cooled version is the separate XE9780L, a 3 OU compute node that lives in Dell’s IR7044 or IR7050 racks.

What changed from the XE9680 to the XE9780?

Dell’s comparison moves the host from 4th/5th Gen Xeon Scalable (up to 64 cores) to Xeon 6 at up to 86 cores, raises memory speed to 6400 MT/s and swaps the H100, H800, H200, H20, A100, MI300X and Gaudi3 boards for HGX B300 or B200. The chassis grows from 6U to 10U, PERC and the LOM disappear, and power moves to twelve 3200 W supplies.

Which operating systems run on the XE9780?

Dell lists Canonical Ubuntu Server LTS with either board and Red Hat Enterprise Linux with B300 only. No Windows Server, SUSE or VMware support appears in the guide, whereas the XE9680 listed SLES and ESXi.

Is the Dell PowerEdge XE9780 end of life?

Dell’s guide gives no end-of-sale or end-of-support date for it, and the August 2026 revision (Rev. A03) still marks several options as post-RTS. Dell’s XE servers carry a standard three-year hardware warranty; our end-of-life checker records dates once Dell publishes them.
