hi all,

think im having some psu problems, my psu is an Antec high current gamer
750w

my system specs are

i7 3770k @ 4.7
2 x 7970 1200/1700

it seems that when my gcards are fully loaded in bf3 for an example and the fan starts to ramp up on the psu [rest of pc is watercooled] sometimes the screen starts to spam out and artifacts.

never happens on valley and never happens if I run a frame limiter.

is it possible that my psu is crapping out once my cards are running flat out?

thanks for everyones replys, can any of you recommend a replacement psu?

would like to carry on running my system at these clocks, after spending a fortune on watercooling I don't plan on underclocking/lowering clocks on anything lol
