ASRock Rack 2U1G-B650/EVAC — 2U Single-GPU Barebone, Short Depth, 1+1 1200 W

A 2U node on AMD’s AM5 socket that takes one full-length, dual-slot GPU and backs it with a genuinely redundant 1+1 1200 W Platinum supply. At 478 mm deep it goes into shallow and wall-mount cabinets that will not accept a normal 850 mm server — which is often the actual constraint in a comms room or at an edge site.

Specification

What it will and will not carry

1200 W redundant against a 170 W CPU leaves real room for the card: a 600 W class GPU fits the budget with margin, and a 300 W Max-Q card leaves the machine barely working. One card is the limit — there is one x16 slot and no second position.

The constraint to watch is memory. AM5 takes UDIMM, capped at 48 GB per module and 192 GB in the chassis. If you size system memory at twice total VRAM, this comfortably carries one 96 GB card and nothing larger. Storage is thin too — two M.2 and one optional 2.5-inch bay — so plan on network storage or keep the dataset on the M.2 pair.

Within those limits it is the cheapest way to put a serious GPU in a rack with redundant power: a single-model inference endpoint, a render or transcode node, a CI runner with a real card in it, or a branch box that has to live in a shallow cabinet.

Rack and cooling

Front-to-back airflow, 24/7 rated. Check the cabinet depth before anything else — the short chassis is the reason to choose this machine, and it is also why it will look lost in a standard 1000 mm rack.

What is included

What is in the box: chassis, backplane, motherboard, the full fan wall and the power supplies listed above, pre-fitted and cabled. It is a complete, working platform less the parts you choose.

What is not: CPU, memory, drives, GPU and any add-in NIC. Those are specified with you and priced separately — that is the point of buying a barebone rather than a finished server.

What Kentino adds

Every barebone we ship is unpacked, assembled, powered up and tested before it leaves Prague: fan wall and PSU redundancy checked, BMC firmware brought up to the current release, IPMI configured and the network details handed over in writing. You get a machine that has already been switched on once by somebody who knows what it should sound like.

Tell us the workload instead of the part numbers and we will specify the CPU, memory and storage for you, build it, burn it in and ship it as a finished server. The same chassis, the same price for the chassis — we simply add the parts and the work.

Price shown is EUR 2,967 excluding VAT for the barebone as described, EXW Prague (Incoterms 2020). Freight, insurance and any destination duties are for the buyer’s account. Typical lead time 10–28 days. Image: ASRock Rack.
