DGX Station GB300 Singapore: ASUS ET900N G3 vs HP vs MSI

Every NVIDIA DGX Station GB300 sold in Singapore is built on the same NVIDIA baseboard: one GB300 Grace Blackwell Ultra Desktop Superchip, 748 GB of coherent memory, up to 20 petaFLOPS of NVFP4 compute and a ConnectX-8 SuperNIC. The OEMs differ in power supply, cooling, chassis, SKU options, management firmware and support, and all of them are price on request. This post compares the ASUS ExpertCenter Pro ET900N G3, the HP ZGX Fury G1n and the MSI XpertStation WS300, with the Gigabyte W775-V10-L01 and Supermicro ARS-511GD-NB-LCC as the other two options we list, and explains which to specify for a Singapore office, lab or data room. For the smaller DGX Spark class, see our Ascent GX10 guide; for the whole ASUS ladder, the ASUS Agent Computer guide.

ET900N G3 vs ZGX Fury G1n vs WS300: specification table

NVIDIA supplies the GB300 baseboard, SOCAMM memory and ConnectX-8 to every OEM, so the 72-core Grace CPU, the Blackwell Ultra GPU with 252 GB of HBM3e at 7.1 TB/s and the 496 GB of LPDDR5X are the same in every tower. StorageReview's 23 September 2026 review of the ET900N G3 ran the same 14-model vLLM sweep it had run on the MSI WS300 a month earlier and found 24 of 28 model-workload pairs within two percent. That is the parity to expect from any of the five; what remains is power supply, cooling, chassis, SKUs, firmware, operating system and support.

Power supply and the Singapore circuit question

All three run a 1,600 W supply and need a dedicated circuit; NVIDIA's reference calls for a 20 A line in North American terms, and in Singapore that means a dedicated 13 A or 15 A socket on its own breaker, confirmed by your electrician against the 230 V supply. The ASUS ET900N G3 uses an 80 PLUS Titanium unit, the highest efficiency tier, which matters when the GPU alone can draw close to 1,300 W: StorageReview logged 1,292 W of GPU power on the MSI with the CPU still at 65 °C. HP's ZGX Fury G1n is listed by a European reseller with a 1,600 W Titanium supply; MSI's WS300 and the Gigabyte W775 use 80 PLUS Platinum units. Gigabyte's page states its supply delivers 1,300 W on 100 to 114 V input and the full 1,600 W on 115 to 240 V, no issue on Singapore mains. On any of them an RTX PRO card shares the 1,600 W budget, and StorageReview notes a large card can reduce B300 performance under combined load; the RTX PRO 2000 is the sensible display card for that reason.

Cooling, acoustics and the optics fan

Every GB300 tower we list is liquid-cooled; 1,400 W of silicon is not practical to air-cool in an office. ASUS fits cold plates to the GB300, the SOCAMM modules and the ConnectX-8, with front and top radiators and a dedicated fan over the QSFP112 optics cages, a detail that matters if you will run 400G fibre transceivers for hours, since hot optics are what throttle a link. MSI uses a 1,400 W-rated liquid module with two 360 mm radiators and one 120 mm system fan; under StorageReview's remote testing the B300 peaked at 71 °C. HP describes direct-to-chip cold plates and closed-loop liquid cooling suitable for office use. Gigabyte pairs its closed-loop cooler with three 120 mm fans. None of the vendors publishes an acoustic rating, so plan for a machine that is audible under load; ASUS rates the ET900N G3 for 10 to 35 °C ambient, which an air-conditioned Singapore office meets with margin.

SKUs, storage and the RTX PRO question

The GB300 has no display output of its own; the Mini DisplayPort that ASUS, HP and Gigabyte expose is a BMC console port. If you want a desktop on the machine itself, you need the optional RTX PRO Blackwell card. ASUS sells the ET900N G3 in four SKUs: 2 SSD, 4 SSD, a -T variant bundled with two QSFP transceivers for 400G fibre, and -Pro2K with the RTX PRO 2000 fitted. HP's ZGX Fury G1n variants on our store are RTX PRO 2000 with 4x 2 TB, RTX PRO 4000 (24 GB) with 2x 2 TB plus 2x 4 TB, and a no-GPU configuration with 4x 2 TB self-encrypting drives; HP arranges the four M.2 slots as a RAID 1 OS pair plus a RAID 0 data pair. MSI ships a 2x 2 TB Micron 4600 RAID 1 boot pair with two expansion slots and supports RTX PRO 2000, 4000 SFF and 6000 cards. Gigabyte's W775 lists the widest card support, up to the RTX PRO 6000 Workstation and Max-Q editions, on one PCIe 5.0 x16 slot plus two x8. For most Singapore deployments the right answer is a headless tower, with the RTX PRO 2000 only if someone will sit at it; the compute is the B300, not the add-in card.

Chassis, weight and rack options

These are heavy machines and the chassis decides how you move and house them. The ASUS ET900N G3 is the lightest at 27 kg and the only one with two top carry handles, the difference between a two-person lift and a trolley. HP's ZGX Fury G1n starts at 41 kg according to the reseller specification, but it is a 5U-rackable tower that ships with rack rails, so a lab that outgrows its office can move the same unit into a rack. Gigabyte's W775 is 29.2 kg net in a 245 mm wide pedestal; MSI has not published a weight for the WS300. For a deskside placement in a Singapore office, the ASUS handles and 27 kg are the practical win; for a planned rack migration, HP's rails are.

Software, management and support

All five ship Ubuntu with NVIDIA's AI developer stack, and all have a BMC with Redfish for out-of-band management; ASUS and MSI use the ASPEED AST2600 with IPMI, and ASUS supports the NVIDIA NemoClaw agent stack under its Agent Computer programme. HP goes further on the enterprise side: the ZGX Fury is certified for Red Hat Enterprise Linux and listed in the Red Hat Ecosystem Catalog, HP and Red Hat have announced a planned Red Hat AI Factory with NVIDIA platform for it, HP pre-installs its Z Runtime CLI for pulling and serving models, and a Windows configuration is available through HP's sales organisation only. That matters if your IT standards are Red Hat or Windows; for a CUDA research team, the Ubuntu baseline on any vendor is what you want. Support is the final differentiator: the ASUS unit carries the official ASUS Singapore warranty and SourceIT commissions it on site; the HP and MSI units follow their own local channels. Confirm warranty terms for each SKU when requesting a quote.

Which DGX Station GB300 should you buy?

ASUS ExpertCenter Pro ET900N G3 for a deskside placement where efficiency, weight and handling matter: Titanium supply, 27 kg with handles, the optics fan for 400G fibre, four clear SKUs and benchmark parity with MSI confirmed by StorageReview. Our ET900N G3 guide covers the numbers. HP ZGX Fury G1n for an enterprise that needs rack rails, Red Hat certification, self-encrypting data drives or a Windows option, and already runs HP Z. MSI XpertStation WS300 for the widest RTX PRO support and the longest track record, as the first GB300 tower independently tested. Gigabyte W775-V10-L01 for RTX PRO 6000 support and three full-length slots. Supermicro ARS-511GD-NB-LCC for a liquid-cooled unit in a Supermicro-standardised data room. If one tower is more than you need, two or four Ascent GX10 units pool up to 512 GB for a fraction of the cost, with the trade-off that clustered inference is slower than one coherent pool; the AI hardware calculator helps size the choice.

Frequently asked questions

Is the ASUS ET900N G3 as fast as the HP ZGX Fury or MSI WS300? Yes. All use NVIDIA's GB300 baseboard; StorageReview found the ASUS within two percent of the MSI on 24 of 28 model-workload pairs.

Why is there no price for any DGX Station GB300? The systems are allocated and configured to order, and suppliers do not permit storefront pricing. Request a quote for your SKU.

Which DGX Station has the most efficient power supply? The ASUS ET900N G3 uses an 80 PLUS Titanium unit; the HP is listed with a Titanium supply; MSI and Gigabyte use 80 PLUS Platinum.

Can a DGX Station GB300 go in a rack? HP's ZGX Fury G1n ships with rails for a 5U rack slot. The others are pedestal towers.

Do I need the RTX PRO card? Only for a local desktop display. Inference and training run on the B300 GPU; the RTX PRO 2000 is the usual choice because it draws the least from the shared 1,600 W budget.

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