NVIDIA DGX Station GB300 in an office: power requirements, circuit, cooling and noise

DGX Station GB300 power consumption and what an office has to provide

NVIDIA rates the power consumption of the DGX Station with the GB300 superchip at 1,600 W of total system power, on its product page and in its datasheet of August 2026, both read on 12 November 2026. On a 230 V circuit this is about 7 A by our estimate, and all of it ends up as heat in the room. In the documents we read, only ASUS states a noise figure: approximately 50 dB in Auto Mode at maximum load without an added graphics card.

This guide covers the installation in an office or a small technical room. The memory figures (748 GB of coherent memory, of which the 252 GB of HBM3e are the GPU memory) are in our article on DGX Station GB300 specs and alternatives, the makers and the order in buying a DGX Station GB300 in the EU.

DGX Station power requirements and the circuit notes, document by document

NVIDIA publishes one power figure and, on two of its regional pages, a circuit note. Input voltage, current, plug, noise, size and weight come from the makers, where they publish them. The circuit notes do not agree with each other, so the table quotes each one with its document.

NVIDIA's DGX Station product pages for the US, the UK and Germany (page metadata of 4 November 2026) and datasheet 5543600 (August 2026); product pages and datasheets of Gigabyte (datasheet updated 27 October 2026), ASUS (datasheet v4, undated), Supermicro, HP, Dell and MSI; all read 12 November 2026. "Not on the page" means that the page we read gives no figure.

The 20 A wording stands on NVIDIA's US and UK pages and on Gigabyte's page; Gigabyte prints it on its German-locale page as well, without a note for Europe. ASUS and Supermicro tie the NEMA 5-20 plug to North America, and ASUS names 200 to 240 V with a regional plug for all other regions. HP's ZGX Fury "requires a dedicated 200–240V AC circuit", is "not intended for connection to a standard 120V household outlet", and HP adds: "Site electrical requirements vary; consult a qualified electrician". No document names a 16 A circuit in words; the figure appears only as the rating of the cord that Dell lists as the default on its German shop page.

Behind these notes is one 1,600 W power supply per system. Gigabyte prints an AC input of "100-240V~, 15-8A, 47-63Hz" and "115-240V~, 15-8A, 47-63Hz", ASUS a system rating of "115-240Vac, 15A-8A, 50-60Hz". Supermicro states 1,300 W at 100 to 114 V and the full 1,600 W at 115 to 240 V, the range in which 230 V mains lie.

A DGX Station on a 230 V, 16 A office circuit

The figures for a European office are our estimate, because no document gives them.

• Current from the power figure. 1,600 W ÷ 230 V = 7.0 A. NVIDIA does not say whether its 1,600 W is taken at the wall or at the output of the power supply. If it is the output, the losses of the supply come on top: at the 94 per cent that Supermicro states for its Titanium unit, about 1.7 kW and 7.4 A.
• Current from the input rating. Gigabyte and ASUS print 15 to 8 A for the input range. We read this as 15 A at the lower and 8 A at the upper end of the voltage range, and we plan with 8 A at 230 V.
• The circuit. A 230 V circuit with a 16 A breaker delivers 3.68 kW. We plan such a circuit at 80 per cent, which is 12.8 A or 2.94 kW, as in our article on GPU server power on 16 A, 32 A and three-phase. One Station at 8 A fits and leaves 4.8 A, about 1.1 kW, for everything else on that circuit. Two Stations on one circuit reach 16 A and do not fit under this rule.

By this estimate one 16 A circuit carries one Station. We recommend a circuit of its own, as HP requires for its version, because an office circuit usually feeds other sockets too. The electrician who plans the room confirms the circuit under local rules.

The 20 A notes fit the same arithmetic at a lower voltage: at 120 V, 1,600 W is 13.3 A by our estimate. This is our reading of why the notes for North America ask for a 20 A circuit and a NEMA 5-20 outlet; the documents themselves give no reason, and NVIDIA's UK page carries the 20 A note as well.

The cord depends on the version and on the outlet. Gigabyte states that the supply "requires C19 power cord" and that power cords are not included with its packages. HP's page names a C20 AC inlet. Dell's German shop page lists as the default a cord from C19 to CEE 7/7, 1.8 m long and rated 250 V and 16 A, and offers C19 to C20 cords as alternatives. A wall socket and a rack PDU need different cords, so the outlet type belongs in the enquiry.

Gigabyte and Supermicro state a single power supply, so their versions have one feed and stop when that circuit trips. No document we read gives guidance on an uninterruptible power supply. How redundant supplies work in rack servers is the subject of our article on power supply redundancy in GPU servers.

How an added RTX PRO card shares the 1,600 W

NVIDIA's product page says the Station "can be configured with up to one additional NVIDIA RTX PRO Blackwell Generation GPU" and lists four cards: the RTX PRO 6000 Workstation Edition, the RTX PRO 6000 Blackwell Max-Q Workstation Edition, the RTX PRO 4000 Blackwell SFF Edition and the RTX PRO 2000 Blackwell. A footnote adds: "Support may vary by system. Check with your OEM to confirm specific support and configurations." ASUS, for example, lists three of the four for the ExpertCenter Pro ET900N G3 and leaves out the 600 W Workstation Edition.

The card does not raise the load on the circuit. The chapter on dynamic power sloshing in NVIDIA's DGX Station development guide describes a "fixed total power budget of 1600 W" that the superchip and the card share; the cap of the superchip falls with the maximum power of the card.

NVIDIA DGX Station Development Guide, chapter "Dynamic Power Sloshing", read 12 November 2026.

In the default Dynamic mode a daemon, vsloshd, moves budget between the two in steps of 50 W every 500 ms and gives the card priority; in Static mode both caps are fixed. By the maximum power in NVIDIA's datasheets, the RTX PRO 2000 Blackwell and the RTX PRO 4000 Blackwell SFF Edition, at 70 W each, fall into the class up to 75 W, the RTX PRO 6000 Max-Q at 300 W into the middle class and the 600 W Workstation Edition into the highest, where the superchip keeps 950 W. This mapping is our reading of the two documents. ASUS attaches a note to the Max-Q in its list: "To ensure optimal stability, an ambient temperature of under 30°C is recommended during heavy workloads."

A monitor needs such a card. The mini DisplayPort on the back belongs to the management controller, and NVIDIA's footnote says it "is intended only for system management". We supply the cards NVIDIA lists for the slot, for example the RTX PRO 2000 Blackwell with 16 GB at 70 W (specs) or the RTX PRO 6000; tell us the maker's version and whether a display is planned, and we reply within one business day. Whether a card is supported in a given version is the maker's statement.

DGX Station cooling and the heat in the room

Electrical power that goes into a computer leaves it as heat. For the Station that is up to 1.6 kW, or about 1.7 kW if the losses of the power supply come on top of NVIDIA's figure. At 3.412 BTU/h per watt this is about 5,460 to 5,800 BTU per hour, by our conversion. Neither NVIDIA nor any maker's page we read states a heat output, an airflow or clearances for a desk.

Four makers describe liquid cooling for the superchip. ASUS writes "closed-loop AIO liquid cooling", Gigabyte "Closed-loop liquid cooling solution" with three 120 mm system fans, Supermicro a direct-to-chip cold plate in a closed loop with five fans, and HP "Liquid cooling and optimized airflow". In a closed loop the liquid moves the heat from the superchip to a heat exchanger with fans, and the room air takes it from there. For the room the type of cooling changes nothing: the same 1.6 kW arrive in the air. HP states that air is drawn in at the front and exhausted at the back, so both ends need free space.

product pages and datasheets of ASUS, Gigabyte, Dell (German shop page), Supermicro, MSI and HP, read 12 November 2026; dimension labels as each maker prints them. Supermicro labels its dimensions for the 5U rack position; standing as a tower, the 454.7 mm side is the height by our reading. HP's QuickSpecs and an MSI datasheet could not be opened.

Gigabyte and ASUS allow 10 to 35 °C in operation, Supermicro 15 to 32 °C. Gigabyte adds a note against condensation: above 50 per cent relative humidity "the coolant inlet temperature must be higher than the dry-bulb temperature" and should not exceed 45 °C. An office with comfort cooling sized for people and laptops may not remove 1.6 kW from one corner of a room, so the facilities team should check the room before delivery. A tower with two RTX PRO 6000 Workstation Edition cards is in the same class at about 1.8 kW by our estimate, and our guide to a GPU server in an office covers rooms shared with people.

The one published noise figure for the DGX Station

ASUS states that its version "keeps acoustics to approximately 50 dB in Auto Mode at maximum load without a discrete VGA". The sentence names no measurement standard, no distance and no weighting, and it applies to the system without the added graphics card. Supermicro writes that its cooling "enables near-silent operation" and gives no figure. The pages of NVIDIA, Gigabyte, Dell, HP and MSI that we read give no acoustic value.

For a desk next to people, ask the maker for acoustic data of the configuration you order, with the added card if one is planned. The other way is to move the system: NVIDIA's specification lists a management controller (BMC) on its own 1 GbE port, so the Station can stand in a technical room and be used over the network. HP describes its version as a tower or a "standard 5U rack" system with rack rails included. Supermicro lists "Tower or 5U" and notes that rack mounting takes 6U, with 1U below the system for power supply venting.

Size, weight and network ports

The towers of ASUS, Gigabyte, Dell and MSI are 231.6 to 245.7 mm wide; of the published depths, Supermicro's 701 mm is the largest. Packed, the systems weigh 32 kg (ASUS), 34.4 kg (Gigabyte, in a carton of 732 × 400 × 775 mm) and 51 kg (Supermicro). Plan two people for unpacking and a place on the floor or on a desk rated for the load.

NVIDIA's specification lists one 10 GbE RJ45 port, one 1 GbE RJ45 port for the BMC and two QSFP112 ports at 400 Gb/s each on the ConnectX-8 SuperNIC. The 10 GbE port goes to the office LAN and the BMC port to the management network. The QSFP112 ports serve a second Station or a 400 Gb/s network; ASUS notes "QSFP Transceiver Required" and sells the transceiver separately. Our article on the ConnectX-8 SuperNIC explains the controller. NVIDIA supports linking up to two Stations; the second one needs a circuit of its own by the arithmetic above.

What to tell us for a quote

We supply manufacturers' versions of the DGX Station GB300 per project. Before we can quote, the distribution asks for the company, the project and the intended use. For the installation, these points settle most questions in advance:

• the maker's version you prefer, or what decides for you: tower or rack, a published noise figure, the weight;
• the place: open office, separate room or rack;
• the circuit: voltage, breaker rating and what else is connected to it;
• the outlet: wall socket or PDU, so that the right cord is quoted;
• the cooling of the room;
• an added RTX PRO card and the displays it should drive;
• the network: 10 GbE, a port for the BMC, and whether the 400 Gb/s ports will be used.

Send us these points through the form or by e-mail to request@eurokommerz.at; we check power and airflow before we quote and reply within one business day. Two versions have articles of their own: the Gigabyte W775-V10-L01 and the ASUS ExpertCenter Pro ET900N G3.
