So i decided to change out the cheap powerup supply in my work computer with my 350 watt 120mm fan fortron that was powering my dual processor machine without a hiccup for over a month...i then decided to put a 530 watt fortron in my dual processor machine (see sigs for both)...
i know that software that reads voltages is not good...however, i figure a comparison of the software read voltages with two different power supplies without changing anything else might be valuable...
the software read voltages on my power hungry dual processor machine:
with 350 watt fortron:
12v=12.10 volts
3.3v=3.34 volts
5v=4.78-4.82 volts depending on processor load
with the 530 watt fortron:
12v=12.10 volts
3.3v=3.3 volts
5v=4.88-4.92 volts depending on processor load
interpretation:
the 5v needs of my dual system are really high due to the overclocked P3's and the multiple drives....thus possibly explaining the better 5v performance out of the 530 watt fortron versus the 350 watter...
the (grossly underrated) specifications on the side of the power supplies are:
12v=16A for the 350 and 18A for the 530
3.3v=28A for both
5v=32A for the 350 and 40A for the 530
also the rated combined 3.3+5v max=220 for the 350watt version and the full 292 watts for the 530 watt version...
bottom line?
i still think and have experimentally observed the 350 watt fortron (rated at 454 watts max by THG and larva) is ample power for my dual machine....but i think the 530 watter is obviously more powerful, which i was thinking will be better for a possible future dual AMD machine...
one final note: the weights of the power supplies
the cheap 350 watt powerup=2.5 pounds measured at work
the 350 watt FORTRON=3.5 pounds measured at work
the 530 watt FORTRON=at least 5 pounds estimated at home
