Help runnig a 8800GTS on 18amp rail

post #1 of 8
Thread Starter 
I have a PSU with two 12v rails putting out 18amps each and dont realy whant to upgrade to a better PSU.the one that i have now runs realy good and sable but it is limiting my overlock to 600/900 on my GTS is there any way that i can get a connector to make it one 36amp rail? or can i just mod it to connect the two cables in to one.

Doesn't matter. What you want to do will have no affect what-so-ever. If the card wasn't getting enough power and tried to draw more, the PSU would just shut off. I can go into confusing PSU design... but I won't.
Once again...

you don't need 26amps just for the gts, it only pulls like 11A, max

Jonny, that's 36A total (about 33A is you take into the fact that he looses some due to the combined rails)

There should not be a problem with your PSU powering the GTS.
