Inno3d 6800GT PCI-E problem

[maxximus123]

Building a system with the skt 939 Asus a8n -sli deluxe(flashed with latest bios 1006).3500 processor,tagan 480 psu, geil mem and an Inno 3d 6800GT 256mb pci-E.
Put simply when i boot the system 50% of time the graphics card fails to power up(fan doesnt turn and get bios beeps saying faulty card).- the card is seated properly and powered by a pci-expess power cable.
Easy answer-RMA it ??? returned it this morning ,replaced with same make and exactly the same problem. Iv even tried using different M/B and power supply.
Iv built quite a few systems of late but this has got me stumped-iv spent hours on this

Any sound advice out there

So you got the same problem with the different motherboard/PSU? That really stumps me. If it's not the card, PSU, or motherboard, I can't think of anything else it could be. Maybe it's how you did your wiring.

Uh, not an expert with PCI-e here, but make sure that when you plug the power connectors to the video card, it comes directly from the PSU, and not through a splitter.

Yeah tried a 680watt thermaltake on the same system and get same problem-half the time it boots as normal and get no probs,rest of time i boot and the card fan twitches and get POST video card failure. Also tried it on a gigabye sli M/B using the Tagan and still this intermittant fault.

Wow you have an awful lot of SLI hardware there.

i had a fan problem where mine was'nt turning on and it got hot, but it was the powersuply which was an antec 350 watt one. it was faulty and killed my card before the warranty ran out so i got a free replacement. now i have a 430 watt one, its fine.

Try another card and see if it will boot without the PCI-E power connected (directly to the card I assume)

Turned out to be a second faulty card from Inno3d. Put in a Gigabyte 6800Gt and had no problems.
