Small Problem im having....

[breadturbo]

My pc has been working all nice up until yesterday, i switched out the gfx card with a better one, PC runs fine but every now and again it will reboot and my asus mobo yells about 'overclocking fail'
Now its run fine on the current settings for years so im wondering if the newer card is overloading the PSU (after a second opinion before i blow cash on a juicy one)

Full spec is.... (including everything power drawing)

Q6600 @3.6ghz (TRUE+noctua nc-12)
4gb geil ram (4x1gb sticks)
9800gx2 (was 8800gtx)
2x 150gb raptors in raid0
2x 250gb sata for storage
1x sata dvdr optical drive
sblive 7.1 soundcard
dlink gbit lan card

then accessories...
logitech g15 keyboard
razer lachesis
saitek X52pro flightstick

besides monitor theres nothing else in there, temps are all low (even in this crappy hot weather)

psu is a hiper 580w type-r rated for 20a rail1, 18a rail2

cheers

hi ..
if ya still got the 8800gtx put that back in an keep ya O/c an see if ya sys is stable !!!

i had that thought also, tried it and it works good, just tried the gx2 in my friends comp and that works good there, so must be psu :/

shopping time methinks lol

just been reading through the nvidia forums, although im not sure how accurate it is, states this....

"Your PSU must supply >40Amps from your 12V rails."

mine falls 2 amps short there without thinking about cpu etc :/
