BFG 6800 Stopped Working

[ikonia]

Hello,

I recently decided to use a an old BFG 6800 in my test PC so that others could join us in some gaming.

Its a BFG 6800 Ultra AGP card in an Asus A8n motherboard. I put the card in, plugged in the dual power connectors and up she came, running like a treat.

I left the PC on over the weekend downloading the 1.6petabytes (joke) worth of Microsoft updates. I came home this weekend to discover the screen is black. Powered the machine off/on and the message "check cable" (no connection) came up on screen. I tried 2 other cables - no joy. Took the lid off the case and the fan is still spinning on the graphics card etc etc. I took the card out and plugged in an old test card, that worked fine. Put the BFG back in - monitor dead again

On checking up on this I noticed that my PSU in this machine was a 400 watt PSU - not a 500 watt as I expected. The notes for a BFG say you need minimum of 480watt.

Questions
a.) could running this with the lower powered PSU have damaged the card ? if so how ?
b.) would you expect the card to work for a day or so of constant use before failing if it was under powered ?
c.) could it be something else (apart from a straight card failure)

Be interested in peoples thoughts who have hardware knowledge.

thanks.

Have you tied the graphics card with a higher wattage PSU? Also what PSU is it that you used?

not tried it with a higher wattage PSU yet - one is being ordered as we speak as even if I need a replacment card I'll need a bigger PSU. The PSU is a tagen.

Although to be fair I suspect the card has a terminal failure, as it "did" work for around a day, then when I came back after the weekend the screen was dead.

I should clarify what I've said above. I think its fatal because it "was" working, now isn't. Therefore if the card was simpley underpowered, I suspect it shouldn't/wouldn't have worked in the first place

Further opinions/knowledge welcome

Just to let you know BFG have in my opinion the best RMA service out there, they had me a new card within 2 days, so if worst comes to the worst, you will be in pretty safe hands.
