It comes with a nice little app called Ptuner to measure your voltages etc.
Here's my system specs:
Intel i7 920 @ 3.8ghz and 1.2 vcore
Zalman 9700Led cooler (temps underload never go over 69 celcius)
Asus P6T Deluxe v1
3x 2gig Kingston HyperX(X.M.P)
MSI Radeon 4870 1Gig @ core 790mhz and mem 1100mhz
1x 750gig Seagate sata
4x 1Tb Seagate sata
6x 1.5Tb Seagate sate
1x LG Dvd writer sata
I've used Extreme Power Supply Calculator and it says that my Wattage is fine.
When I use Ptuner however I'm not so sure. My wattage hits 500 very seldom so that's fine, but I'm worried about my Amp usage on my 12v rails.
Ptuner says that my 12 rails run as follows:
Rail 1 runs at 4.5amps, Rail 2 runs at 5.5amps, Rail 3 runs at 11-17amps, and Rail 4 runs at 5amps.
My 5volt runs at 8amps and my 3.3volt runs at 8.3
These measurements were taken running Prime95(8 threads) and Folding@Home gpu client
Ptuner says I have a max of 18amps per 12v Rail.
Is my pc at risk? Is my psu too "light" for the job?
