Which Gigabyte servers take the NVIDIA RTX PRO 6000 Blackwell Server Edition: 4 or 8 cards

Gigabyte GPU servers that name the RTX PRO 6000 Blackwell Server Edition

Gigabyte names the NVIDIA RTX PRO 6000 Blackwell Server Edition on the product pages of nine rack servers, as read on 12 November 2026. Four of them take eight cards: the 4U XL44-SX2-AAS1, the liquid-cooled 6U XLS4-SX2-LAS1 and the 4U G494-SB4-AAP2 and G494-ZB4-AAP2. Five 2U models are named for four cards, and for seven of the nine servers Gigabyte ties the card count to an ambient temperature of 25 °C.

The server business behind the brand signs its press releases as "Giga Computing, a subsidiary of GIGABYTE Group", while product pages and datasheets carry the GIGABYTE name. Its RTX PRO solutions page describes the card with "96 GB GDDR7 with ECC" and "up to 600W (configurable)". The card is passive, so the fans of the chassis and the maker's validation decide where it runs. That rule and the models of other makers are in our article on RTX PRO 6000 Server Edition compatible servers, the card's own figures in the RTX PRO 6000 Blackwell specs.

We supply Gigabyte, Supermicro, ASUS, Dell and HPE servers per project. Send us the card count and the rack the server goes into, and we reply with a configuration and a written quote within one business day.

Gigabyte's product pages for the nine models (copyright line 2026) and the datasheets of the XL44-SX2-AAS1 (last updated 21 July 2026) and the G494-SB4-AAP2 (last updated 20 July 2026), read 12 November 2026. All power supplies are 80 PLUS Titanium.

The list follows Gigabyte's RTX PRO solutions page and the product pages it leads to. The filtered server listing and the qualified-vendor lists load their rows only in a browser and could not be read, so further models may exist. Every count is the one Gigabyte states for that model, whatever the number of slots.

Eight cards in 4U with the XL44-SX2-AAS1, Gigabyte's NVIDIA RTX PRO Server

Gigabyte titles the XL44-SX2-AAS1 "NVIDIA RTX PRO Server - 4U DP 8 x NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs". Its page describes a complete GPU configuration: "Configured with 8 x NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs" and "Configured with 1 x NVIDIA BlueField-3 DPU". The server is "Built on the NVIDIA MGX architecture", which our guide to NVIDIA MGX servers explains. The page lists the eight cards "via ConnectX-8" with PCIe Gen6 switching, and the rear panel has eight QSFP ports of 400 Gb/s for InfiniBand or Ethernet, which Gigabyte assigns to GPU networking.

The table in the next section sets its figures next to the G494. The operating range ends at 30 °C, and Gigabyte publishes neither a weight nor a maximum memory capacity for the model. Its page makes no NVIDIA-Certified statement; NVIDIA's RTX PRO Server page of 11 June 2026 lists GIGABYTE among the system partners and states that "RTX PRO Servers are NVIDIA-Certified".

Gigabyte's press release of 4 November 2025 counts "up to eight NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs" as 768 GB of GDDR7. By our users-per-card rule, 664.3 GiB of that holds model weights and KV cache; which LLMs fit eight RTX PRO 6000 Server Edition cards works through the layouts.

The XLS4-SX2-LAS1 is the 6U version with direct liquid cooling: "Configured with 8 x liquid-cooled NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs", with liquid-cooled processors and memory, six 3,200 W supplies and a coolant inlet of at most 45 °C. It measures 438 × 264 × 805 mm and weighs 108 kg net; liquid cooling for GPU racks describes what the rack has to provide.

The G494 with eight RTX PRO 6000 cards and Gigabyte's conditions

The G494 is Gigabyte's general 4U chassis for eight double-width PCIe cards, in an Intel version (G494-SB4-AAP2) and an AMD version (G494-ZB4-AAP2). Both pages state "Supports up to 8 x dual-slot Gen5 GPUs". The RTX PRO 6000 Blackwell Server Edition appears one level lower, under the heading "Conditionally supports", as "8 x NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs" next to eight H200 NVL with 4-way NVLink bridges. Three notes define the condition:

• Temperature. "The system supports 8 x NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs at 25°C ambient." The chassis itself is listed for 10 to 35 °C.
• Fan kit and depth. "The system supports up to 8 x 600 W GPUs with an optional fan kit." The SB4 page lists it as "8080 fan kit for 600 W GPUs" with the order number 6NG494SBXK002AFN001. Gigabyte prints two sizes, "448 x 176 x 880" and "448 x 176 x 1000.5 (with optional fan kit)".
• One GPU model. "The system is only validated with a uniform GPU model."

A G494 for eight of these cards is therefore a server of 1,000.5 mm depth for a room that holds 25 °C.

Each set of four GPU slots hangs on its own PCIe switch: the pages list "4 x FHFL x16 (Gen5 x16), from PEX89144_0, for GPUs" and four more from PEX89144_1. Gigabyte does not use the words single root or dual root for this.

Gigabyte's product pages for the three models and the datasheets of the XL44-SX2-AAS1 (last updated 21 July 2026) and the G494-SB4-AAP2 (last updated 20 July 2026), read 12 November 2026. Each model also has one management LAN port. The EPYC model allows a cTDP of up to 500 W "At 30°C ambient".

The package of a G494 includes eight 16-pin GPU power cables of 150 mm, two CPU fansinks and a rail kit. Gigabyte does not say what the net weight of 66.8 kg includes. Neither G494 page mentions MGX or NVIDIA-Certified. NVIDIA's own list of NVIDIA-Certified Systems (last updated 4 October 2026), read 12 November 2026, carries the G494-ZB4-AAP2 with the RTX PRO 6000 Blackwell Server Edition in its table of eight-GPU PCIe reference configurations.

Four cards in 2U with the G294, XV23 and XV24

Five 2U models are named for four cards, each at 25 °C ambient. The XV24-SU0-AAJ1 page, for example, reads "The system supports 4 x NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs at 25°C ambient."

Gigabyte's product pages for the five models, read 12 November 2026. Processor power is the base figure: Gigabyte allows 500 W in the XV23 and 300 W in the G294-Z42 at 30 °C ambient, and 300 W at 30 °C or 350 W at 25 °C in the G294-S42. The G294 depth includes 112 mm of rear fans. The G294-A22 has an operating range of 10 to 30 °C.

The three G294 models put eight double-width slots behind one PCIe switch, listed as "8 x FHFL x16 (Gen5 x16), from PEX89048, for GPUs". For this card Gigabyte still names four: eight of them in 2U are not a configuration on any Gigabyte page read.

The XV23-ZU0-AAJ1 and XV24-SU0-AAJ1 are single-socket NVIDIA MGX servers with four GPU slots. Both models keep two further full-length x16 slots for NVIDIA ConnectX-7 NICs and one for a BlueField-3 DPU.

The XV23 and XV24 have four 2,000 W supplies in 3+1, and the XV23 page adds "2+2 PSU redundancy supported for GPUs below 400 W." Four 600 W cards therefore run in 3+1. The G294 models have "Dual 3000 W 80 PLUS Titanium redundant power supplies". By our estimate a four-card server draws about 3.4 kW at the wall with two AMD EPYC 9355 processors, or about 2.7 kW with the cards capped at 450 W. The G294 pages read name no condition for redundancy, so ask in writing whether one 3,000 W supply carries your configuration alone.

Models and users of a four-card build are in four RTX PRO 6000 Server Edition cards in one server, the chassis question in 2U or 4U for four cards.

Two cards, the G493 and model names that look alike

No Gigabyte page read names a configuration with two RTX PRO 6000 Blackwell Server Edition cards. Whether a four-card 2U model is built with two is a question for Gigabyte and is settled with the quote.

The suffix of the model name matters. The G294-S42 and G294-Z42 also exist as -AAP1 models; only the -AAP2 pages were read, and they are the ones that name the card. Three neighbouring models are easy to confuse with the nine above:

• The G294-S43-AAP2 is a 2U server for 16 single-slot cards. It names "16 x NVIDIA RTX PRO 4500 Blackwell Server Edition GPUs at 25°C ambient" and not the RTX PRO 6000. That card has 32 GB and 165 W: see the RTX PRO 4500 Server Edition specs and the page to buy the RTX PRO 4500 Server Edition.
• The XL44-SX0-AAS2 is an NVIDIA MGX server with the outer dimensions of the XL44-SX2-AAS1 and eight GPU slots wired to the two processors. Its page names no GPU model.
• The G493-ZB4-AAP1, the previous generation with AMD EPYC 9004, carries the label "Legacy | Firmware updates supported". Its page names neither the RTX PRO 6000 Blackwell Server Edition nor the H200 NVL.

Power feeds, rack depth and inlet temperature

By our estimate an eight-card server draws about 6.3 kW at the wall at 600 W per card, above the 5.89 kW we plan for one 230 V 32 A feed at 80 per cent, and about 5.0 kW at the 450 W cap; GPU server power on 16 A, 32 A and three-phase feeds shows the arithmetic. What the supplies deliver depends on the model and on the input voltage:

• XL44-SX2-AAS1. The 3+1 layout is stated. Each supply delivers 3,200 W at 220 to 240 V and 3,000 W at 200 to 220 V, so three of them carry 9.6 kW or 9.0 kW by our arithmetic.
• G494. Gigabyte writes "Quad 3000 W 80 PLUS Titanium redundant power supplies" and states no mode. A supply delivers 3,000 W at 220 to 240 V and 2,600 W at 200 to 220 V on the SB4 page, 3,037.2 W and 2,598 W on the ZB4 page. By our arithmetic three supplies give 9.0 kW or 7.8 kW, and two give 6.0 kW or 5.2 kW. Ask for the mode with eight 600 W cards in writing before the feeds are planned.

A 3+1 layout tolerates the loss of one supply. Only N+N layouts can be divided over two feeds A and B, as PSU redundancy in GPU servers explains. The G494, XL44 and G294 pages ask for C19 power cords and state "Power cords are not included with server packages." The order therefore includes one cord per supply.

Depths run from 802.5 mm for the XL44 to 1,000.5 mm for the G494 with its fan kit. For eight RTX PRO 6000 cards that last figure is the one to plan with, and it is longer than a cabinet of 1,000 mm is deep; our site survey for GPU servers lists the measurements to take.

Measure the air temperature in front of the rack position before the order; GPU server inlet temperature explains where. We check rack, power and airflow before we quote: tell us the usable rack depth, the feeds and the measured temperature.

What to state in an enquiry for a Gigabyte GPU server

Five points let us quote a Gigabyte server without a second round of questions; our page to buy a server with eight RTX PRO 6000 Server Edition cards shows a complete build.

1. Card count and power per card. Four or eight cards, at 600 W or at the 450 W cap.
2. CPU platform. Intel Xeon 6700/6500, AMD EPYC 9005/9004 or, in the G294-A22, Xeon 6900. Our reference configurations follow NVIDIA's certified-systems guidance: at least six cores per GPU and at least twice the GPU memory as system memory, which is 768 GB for four cards and 1,536 GB for eight.
3. Power feeds. Voltage, the number of feeds and phases, and the outlets on the PDU.
4. Rack depth and temperature. The usable depth of the rack and the air temperature at its front.
5. Network and software. NICs or DPUs, and whether the cards are shared: NVIDIA lists the Server Edition for vGPU from release 19.0 and for MIG with up to four instances per card, as our pages on RTX PRO 6000 vGPU profiles and MIG profiles set out.

Gigabyte's pages give a barebone order number for each model, for example 6NG494SB4DR000AAP2 for the G494-SB4-AAP2; barebone or complete GPU server describes how such a base unit becomes a quoted system. Our servers are assembled and tested before delivery. Gigabyte's warranty page for enterprise products, undated with a 2026 copyright line, gives servers and barebone systems "a three (3) year limited warranty" from the invoice date unless agreed otherwise in writing, and it states no terms for Europe. In an order from us the manufacturer warranty is handled through us, as GPU server warranty in the EU explains.

If the maker is still open, Supermicro vs Gigabyte vs ASUS compares 8-GPU servers of three makers, and ASUS ESC8000 for the RTX PRO 6000 Server Edition is the counterpart of this page.
