I thought I remembered seeing in a UCS preso that the only time a UCS actually "required" more than 1x PSU was when you put in a B440 or B230 since they support the Xeon x75XX processors.

I have a UCS in my lab with 8x B200M1 and one of the PSUs is in a standby state leaving only 3 active. I also just took a look at UCS manager and each of the 3 PSUs that are active are only drawing about 425W.

I think unless you are running all of the blades at 100% capacity and 100% CPU, 100% of the time, you probably won't see 10000W usage.

I am new to UC on UCS and need some advise on the basic power requirements for UCS 5108. We are going to use 8 x B200M2 servers (full load) with 4 power supplies (2500W each) in single 5108 chassis and grid redundancy mode is desired.
Does this mean we need to have 10000 watt power for fully loaded single UCS 5108 system if not, what would be the best practice for this?
Your advise is much apreciated.
