NVIDIA DGX Station GB300 Singapore: Buyer's Guide 2026

The NVIDIA DGX Station GB300 is a deskside AI supercomputer: one GB300 Grace Blackwell Ultra Desktop Superchip, 748 GB of coherent memory and up to 20 petaFLOPS of FP4 compute in a liquid-cooled tower that runs from a wall socket. In Singapore, SourceIT lists five OEM versions of it, from ASUS, HP, MSI, Gigabyte and Supermicro, all price on request. This buyer's guide explains what the platform is, puts the five towers side by side, says who each one suits, and answers the pricing, lead-time, power and warranty questions that come up on every quote. It is the hub for our DGX Station coverage; the model guides and the ASUS Agent Computer guide are linked throughout.

The five DGX Station GB300 towers sold in Singapore

Each row uses that OEM's own published figures, except the HP power supply, which comes from an HP reseller specification because HP's product page does not state it. Every unit is price on request on our store.

What the NVIDIA DGX Station GB300 platform is

NVIDIA's reference specification is the same behind all five towers. The GB300 Desktop Superchip pairs a 72-core Grace CPU (Arm Neoverse V2) with a Blackwell Ultra GPU over NVLink-C2C. The GPU carries 252 GB of HBM3e at 7.1 TB/s; the CPU carries 496 GB of LPDDR5X at 396 GB/s; together they form 748 GB of coherent memory that the GPU can address directly. FP4 Tensor Core performance is rated at up to 20 PFLOPS with sparsity. A ConnectX-8 SuperNIC provides two QSFP112 ports at 400 Gb/s each, up to 800 Gb/s aggregate, plus 10 GbE for the host and 1 GbE for the BMC. NVIDIA specifies four M.2 Gen5 slots and ships Ubuntu with its AI developer tools.

Performance is therefore a platform property, not a brand property. StorageReview's 23 September 2026 review of the ASUS ET900N G3 found it within two percent of the MSI WS300 on 24 of 28 model-workload pairs, with GPT-OSS-120B at about 9,300 tokens per second, roughly three times a single RTX PRO 6000 and 18 times a DGX Spark. Our ET900N G3 guide has the full figures, and the three-way comparison digs into the ASUS, HP and MSI chassis.

Cooling, power supply and chassis: where the OEMs diverge

All five are liquid-cooled, because 1,400 W of silicon is not practical to air-cool in an office, but the implementations differ. ASUS puts cold plates on the superchip, the SOCAMM memory and the ConnectX-8 and adds a dedicated fan over the QSFP112 optics cages, a detail that matters if you run 400G fibre transceivers for hours. MSI's liquid module is rated for 1,400 W and feeds two 360 mm radiators; StorageReview saw the B300 peak at 71 °C with the GPU drawing 1,292 W. Gigabyte pairs its loop with three 120 mm fans, Supermicro with five fans across three sizes, and HP describes direct-to-chip cold plates suitable for office use.

Power supplies are all 1,600 W, but the efficiency tier splits the field: ASUS, HP and Supermicro are Titanium, MSI and Gigabyte are Platinum. Gigabyte states that its supply delivers 1,300 W at 100 to 114 V and the full 1,600 W at 115 to 240 V, which Singapore's 230 V mains comfortably meets. Chassis weight ranges from the ASUS at 27 kg with carry handles, through the Gigabyte at 29.2 kg, to the Supermicro at 40 kg and the HP from 41 kg; HP and Supermicro fit a 5U rack, and HP includes the rails.

Storage, the add-in GPU and out-of-band management

The GB300 has no display output of its own; the Mini DisplayPort on these towers is the BMC console. If someone will sit at the machine, you need an RTX PRO Blackwell card in the PCIe 5.0 x16 slot. ASUS offers the RTX PRO 2000 on its -Pro2K SKU; HP offers the RTX PRO 2000 or RTX PRO 4000; MSI, Gigabyte and Supermicro list cards up to the RTX PRO 6000. A large card shares the 1,600 W budget with the B300, so the RTX PRO 2000 is the sensible display card unless you have a separate workload for it.

Storage follows NVIDIA's four-slot layout with OEM variations. HP arranges its four M.2 slots as a RAID 1 operating-system pair plus a RAID 0 data pair and offers self-encrypting drives; Gigabyte and Supermicro expose the two ConnectX-8-attached slots as PCIe 6.0; MSI ships a 2 TB Micron 4600 RAID 1 boot pair. Every unit has a BMC with Redfish, so IT can manage it like a server; ASUS and MSI use the ASPEED AST2600, Supermicro adds a NIST 800-193 Silicon Root of Trust, and HP integrates NVIDIA Data Center GPU Manager telemetry.

Who each DGX Station GB300 suits

ASUS ExpertCenter Pro ET900N G3: deskside placement where weight, efficiency and handling matter, and buyers who want the official ASUS Singapore warranty with SourceIT commissioning; it is the ASUS Agent Computer flagship. HP ZGX Fury G1n: enterprises standardised on HP Z, anyone who needs Red Hat certification, self-encrypting data drives or a path from office tower to rack; see the ZGX Fury G1n guide. MSI XpertStation WS300: the longest independent test record and the widest RTX PRO card support with a Platinum-rated supply; see the WS300 guide. Gigabyte W775-V10-L01: HPC and research teams already running Gigabyte servers, and buyers who want RTX PRO 6000 support in a lighter pedestal; see the W775-V10-L01 guide. Supermicro ARS-511GD-NB-LCC: Supermicro-standardised data rooms that value a hardware root of trust and a chassis that converts to 5U; see the ARS-511GD-NB-LCC guide.

How DGX Station GB300 pricing works in Singapore

None of the five carries a storefront price, and that is a supplier condition rather than a SourceIT choice. GB300 units are allocated and configured to order, so each quote is built per configuration: the GPU add-in card (none, RTX PRO 2000 or a larger card), the SSD count and capacity, whether QSFP transceivers or DAC cables are bundled, and the support term. The AI hardware calculator helps you decide which configuration to ask for. If the budget is a question, the DGX Station vs DGX Spark post sets out when a GB10 unit, or a cluster of them, is the better buy, and the local AI vs cloud API cost model frames the payback.

Lead time, power and warranty: the questions on every quote

Lead time. GB300 allocations change month to month and differ by OEM, so contact us for the current lead time on the model you want; engage early for tender or multi-unit orders. Power. Every tower uses a 1,600 W supply and needs a dedicated circuit on Singapore's 230 V mains, confirmed by your electrician; Gigabyte's page states a 20 A circuit requirement outright. SourceIT runs a pre-delivery site check. Warranty. The ASUS unit carries the official ASUS Singapore warranty; the HP, MSI, Gigabyte and Supermicro units follow their own local channels, and terms vary by SKU, so confirm the term when requesting a quote. Operating system. All ship Ubuntu with NVIDIA's AI developer tools; HP adds Red Hat certification and offers a Windows configuration through its own sales organisation.

Frequently asked questions

What is the NVIDIA DGX Station GB300? NVIDIA's reference design for a deskside AI supercomputer: a GB300 Grace Blackwell Ultra Desktop Superchip with 748 GB of coherent memory, up to 20 PFLOPS FP4 and a ConnectX-8 SuperNIC, built as towers by ASUS, HP, MSI, Gigabyte and Supermicro.

How much does a DGX Station GB300 cost in Singapore? Price on request. Units are allocated and configured to order, and quotes are built per configuration: GPU add-in card, storage, transceivers and support term.

Which DGX Station GB300 is fastest? None meaningfully. All share NVIDIA's GB300 baseboard; StorageReview measured the ASUS ET900N G3 within two percent of the MSI WS300 on 24 of 28 model-workload pairs.

Which DGX Station OEMs use a Titanium power supply? ASUS and Supermicro publish 80 PLUS Titanium; HP's is Titanium per its reseller specification. MSI and Gigabyte use 80 PLUS Platinum.

Can a DGX Station GB300 be rack-mounted? The HP ZGX Fury G1n ships with rails for a 5U slot and the Supermicro chassis converts to 5U. ASUS, MSI and Gigabyte are pedestal towers.

What power does a DGX Station need in a Singapore office? A dedicated circuit for the 1,600 W supply on 230 V mains, confirmed by your electrician. SourceIT checks the site before delivery.

Does a DGX Station GB300 need the RTX PRO card? Only for a local desktop display. The B300 GPU does the AI work; the RTX PRO 2000 is the usual choice because it takes least from the 1,600 W budget.
