769855 2009-05-01 00:50:00 I am having an issue which I am pretty certain is caused by my PSU. My video card only works in a PCIe x8 slot, and then sometimes when I try to boot, I get a 'no video card or bad video RAM' BIOS beep. Switching the PSU off for 10-20 minutes temporarily fixes this. My video card worked fine in a friends PC at x16 speed, so I'm pretty sure it's not the problem. I think maybe the video card doesn't work in the x16 slots because my PSU can't provide enough power, does this sound about right? If so, how much power do I need? sammo450 (13626)
769856 2009-05-01 01:29:00 First thing I would do , is get hold of a known good PSU and attach it to your PC and see if the problem still exists.

If it doesn't - Replace the PSU, if it does still exist on a Different PSU, could be a fault on the Board - no piont in replacing parts only to find out its the wrong part - process of elimation to find the fault.

769857 2009-05-01 01:46:00 In my original mobo, yes. Never had it going at x16 in my new mobo. The guy I got it off said he didn't have any problems. It is a pretty heavy sort of a motherboard I think. The manual recommends at least 600W, my current PSU is only 450. And I'm only using a 4-pin 12V connector when I think I need an EPS12V 8-pin connector. sammo450 (13626)

Like he said................and if the PSU is fine, then look at the card itself.

769859 2009-05-01 04:17:00 OK then I think I may have some difficulty trying to borrow someone's newish PSU. Do businesses usually hire out things like that? sammo450 (13626)
769860 2009-05-01 04:50:00 Hire? What would they charge, 1-2c a day? Buy one theyre not that dear Speedy Gonzales (78)
769861 2009-05-01 04:59:00 On minimum wage working a few hours a week they are pretty expensive :P I'm looking at around $120 minimum for something of at least 500W. sammo450 (13626)
769862 2009-05-01 05:36:00 On special here:

Its 430w but can probably output more than that, very stable, modular

769863 2009-05-01 05:43:00 Take it in to a shop then. Some don't charge for the diagnosis - I didn't - then you can just pay for whichever bit is dead if not still under warranty.
If any of it is, then you should take it back anyway.

769864 2009-05-01 05:49:00 It doesn't look modular... And I'd rather have a 120mm fan, and at least 500W just to be safe. Thanks for the suggestion though. @PCTech - I bought a case/PSU combo, and have started modding the case so warranty probably doesn't apply unfortunately. I'll see if any local shops will do a free diagnosis. sammo450 (13626)
