Anyway, i just tested the theory that 2 psu's have a higher power usage, and this seems to be false.
I have a 800VA ups, which measures the exact usage that is drawn from its battery, and it is exactly the same when i connect everything to my main psu and when i use both psu's.
In idle, i use 189 watt in both cases, there is not even 1 watt of difference between using 1 cpu or both. Also with various games, it loads with the same amounts.
I guess the explanation can be found in the fact that the load from my pc equipment is exactly the same, it wil only be steadier when using 2 psu's instead of 1. |
