Power usage advice

Could anyone advice the power usage of these to colo them, need to know the approx amp usage

Supermicro CSE-815 Server - 2 x AMD Opteron 12/C 6174 2.20GHz / 128GB RAM 4 x 1TB SATA drives (1 Server)
Supermicro 818-14 Server - 4 x AMD Opteron 8/C 6128 2.00GHz / 64GB RAM (16x4GB) 2 x 1TB drives (3 servers)

    I always ask for 10 Amps for each server.
    That's the value labeled on the PSU, so you can't go wrong with that.

    To get more precise, you need to measure the hardware with an electric current meter.
    Measure, don't guess.

  • I have not yet bought these, If i ask for 10 amps i would be paying a starting fee to of about £430 to colo the server

    Ask the seller?

    Anyway, I always ask for 10 Amps for each server.

    How to file a copyright complaint against the Nigh Sect copying my witty comments?

    Both servers roughly 300watts

    So your at a rough of 15amps 120V or a 10amp 240V.
    You can maybe snake a 10amp 120v but if you blast all CPUs you will trip a breaker.

    Are you sure about that math?

    ....Amps multiplied by Volts equals Watts,
    ....So therefore (W)/(V) =(A) ..... 300w / 120v = 2.5A

    Realistically you will observe a bit of fluctuation down to 110v or so.
    300w / 110v = 2.7272...A

    For .eu you can expect to see a swing from 220 to 240V in normal Buildings with 208v for some DC locations.

    I took 300watts X 4servers = 1200watts total.
    1.2kw / 120v = 10amps
    1.2kw / 240v = 5amps

    But Most DCs don't want you over the 80% circuit load. That's why I said 15amps 120v and 10amp for 240V. (1.44kw 80% 120V -- 1.92kw 80% 240V)

    With 240V they will have some room to grow. With 120v they are pretty maxed out if sticking with the 80% rule.

    now the math makes sense :smile:

    You had me double checking it going great what did I mess up.. :)

    These numbers though are maximums though. I guess all depends on what DC they get at.

  • Those CPUs are really old, you would most likely get more value buying something newer. You'd also save a fortune on power cost.

    I agree a modern single CPU will have better performance vs 4x Opteron. and pay for itself in power savings within a year.
