Yep I have the custom fan set up, I've set it to get to 100% (which is only 85%) at 75*C.
Although everything seems alright, we still haven't figured out why my pc hard resets with furmark which was the main topic of this thread
But anyway thanks a lot for everything.
So no last thaughts about the PSU? Is there a way to test the PSU to make sure that it isn't the problem?

furmark is rather flonky - it pushes gpus too far at times, esp the higher up 5xx nvidia series. if you look back at the power consumption using furmark that 580 of your would hit over 300 watts and the card is not designed to go that high @ 244 watts according to the specs on nvidia's page:
GeForce GTX 580 Specifications Maximum Graphics Card Power (W) 244 W
some of that might be all well and fine, pushing it that hard temporarily but, i think with your psu having four 12 volt rails might have caused an issue. hopefully i can explain it correctly and pardon me if i put it too simplistic. if you look at the power connections coming off the psu for the motherboard, the sata, the 4 pin molex, 4/8 pin cpu power and pci power connections you see the yellow wires are 12 volt.
now supposedly the cpu gets its own 12 volt rail, that would be the 4/8 pin connection. so that theoretically leaves three of the four rails left.
the motherboard connection supplies the 12 volts to the pci-e x16 slot to supply 75 watts (also the x1 slot is supplied ~10 when used, i think) each 6 pin power connection for the gpu is also 75 watts and the 8 pin are 150 watts. so you have 5 power connections (3 of them 75 watts and 2 with 150 watts) being distributed among three 18 amp rails. that would mean two pair of something is sharing a rail for each pair and one connection would have it own rail.
now i am guessing that an 8 pin power connection has its own (150 watts), a 6 pin is sharing with the motherboard to supply the pci-e slot (150 watts), and a 6 pin is sharing with an 8 pin (225 watts). thats all fine and dandy but for the 6/8 pin sharing since 18amps*12volts is 216 watts, that would trip the over currant protection. again i am completely guessing but thats why i asked you to switch power connections to the card. if you are using the 8 pin that isn't sharing with the 6 pin that is sharing with the 8 pin but isn't being used then the motherboard supplying to the pci slot and each of the two power connections to the card will be on their own 12 volt rail.
before it really isn't a problem until you try using furmark and it causes the card to draw more power than it was designed to do. then the psu does what it is suppose to do, shut down when the over current protection kicks in.
i hope that made sense and i am somewhat close to being correct. - ooops i just thought that i forgot about the 12 volt to the sata and molex power connections . i guess that 8 pin that isn't sharing might be sharing with those. but the power draw on that is very minor, ~ 5 watts a connection, if that. but let me reassure you the psu is fine, you just hit a small bump in the road that can happen on a multi rail system from time to time.









SO I've used the 8 pins cable that says VGA1 and used the 6 Pin cable that says VGA 2 and TADA
