Figuring PSU and UPS for a 2P/2GPU server
Posted: Sat May 03, 2014 1:09 pm
For my long-wished-for server, I have calculated my PSU needs to 1,259 watts. A reasonable rounding-up would put me into a 1500 Watt PSU.
I need to know how much UPS capacity I will need for a system roughly meeting the specs below.
Proposed System:
Purpose: F@H and remote graphic art rendering. Depending on location in the house, it can/will also serve as a guest room/kitchen nook web browser. 90% of the time, this machine would be a single-user server, running F@H CPU and GPU slots in the corner of the house. At first I'll use Windows 8.1 for the OS. Eventually, I may try to go in the direction of VM-hosted Windows + Linux (concurrently running), but that is on the "later" list.
Hardware:
Dual E5 V2 processor (figure 2 hex-core or octo-core CPUs for total cores/threads = 12/24 or more (depending on finances)
16 to 32 GB RAM (depending on finances)
1 X AMD R9 290 x GPU cards (no crossfire; they'll be folding and running remote OpenCL rendering)
-----> ** see GPU note below
1 X Monitor (23" or 27"; whatever's handy and fits in the space)
1 X or 2 X SSDs (512GB)
1 X HDD (2TB, 3TB, or 4TB for network-based backups. HDD will always be in place)
WIFI connectivity
Basic audio, keyboard, mouse
Cooling:
2 X H80 or H100 type CPU cooler (1 for each processor slot)
No water cooling for the GPUs (not immediately anyway)
Big case fans (think along the lines of HAF-X, HAF-932, HAF-XB)
------> GPU Note:
My pie-in-the-sky plan would prefer dual GPU cards; so 2 cards for a total of 4 GPUs. Nobody's making 'em right now but even so, I would like to budget my PSU and UPS capacities on the high side.
