  1. The first one has a combined current of 36 A on the +12V rails, power o/p on the same is 432 W
    The second one gives 40 A total on +12V, but a power of only 400W. It's less efficient.
    Also the first one seems to have more power connectors.
    So I'd say the first one is the best bet (assuming both are equally priced)
  2. I wouldn't purchase either one.... and instead look for something on here:

    First one is a 64 eura
    Second is a 58 eura in Croatia.

    Im for first one, just becouse can produce 40A and have 6 Sata, but have one less power connector...

    Thank you...
  5. Well unless you plan on using 6 HDDs, the 6 SATA cables are just a gimmick. Realistically, you'l use 2, maybe 3 HDDs. So that's no issue .
    Btw, actually, the 2nd one has 6 sata & 40A.
    Looking at the price diff, now I'd say the 2nd one is better.

    ksampanna, you cannot just add up rail capacity. Each rail can provide a max of 20 amps. However, the second line will give you the maximum 12 volt power which is 432 watts - or 36 amps.

    If true, considering that a 550 watt Corsair puts out 41 amps, that's a reasonable amount of power for a 500 watt PSU.

    What you say for other one, this PSU have two 12V rails and max 40A. Leave these +32W from CHP-500A who have 432 max load in second line. For me is enought 400W (i mean in second line)
