tri sli GTX480 power problem

post #1 of 23
Thread Starter 
As u can see from my sig I'm running 3 480s. When I run benchmarks with all 3 enabled, no o.c. or anything where it runs them all 90%+ load my rig shuts down. The cards have all been tried in all combinations running alone and with one other card, also tried all 3 cards in different positions running trisli. I've ruled out everything and it seems that the cards arent getting enough juice. My psu, silverstone strider 1200w, should be enough for these 3 cards.

Here is how they are currently connected to the psu
GPU1 6pin + 8pin

GPU2 6pin + 8pin

GPU3 1 psu sata power cable to molex to 6pin + 2 separate molex cables to 2 6pin adapters to 1 8pin.

Would the connection for gpu 3 be doing it, should be getting the proper power, but am not sure. Can anyone help with this?

That should be plenty enough power, assuming you're balancing your rails.

If they are balanced, I can't see what else would be causing your shutdowns other than just a faulty PSU.

If you have spare adapters for the last card, try those.

Also, are your cards overclocked at all? 1200 provides pretty much nothing in terms of OCing headroom with 3x 480s.

Scratch that, I missed that bit.

take out the psu and test all the rails tomorrow, I really don't think there's anything wrong with it. Maybe disassembling and reassembling my entire pc will work... worth a shot

He's already stated that he ran his cards without an OC.

Try unplugging all your optional cables for optical drives/fans/lights (use a spare/test PSU to power your fans if you can) and try running it that way.

My guess is your pulling too much off the molex connectors. Molex lines aren't meant to support the huge amount of current that a GTX 480 would pull.

I am using all of the spare adapters that came with all 3 cards, tried the different 6 to 8 pins I wasnt using. Cards are not voltage overclocked, but overclocked to SC specs from vanilla

90 amps on a single rail is plenty unless something is wrong with it. It suppose to have Dual PCI-E 8pin & Six PCI-E 6pin connectors, isn't that enough for 3 GTX480's?

My sig rig barely hits 500w with both GPU's running at 100%.
