Hi, I had some old components lying around which only needed a new mother board, so I rebuilt it. But I tried switching the pc on, the fans would flicker to life for a second before it switches off. It's an amd athlon 64 processor and I've plugged the fan and the atx four pin socket in, also plugged into the power is the dvd rw drive, a 160gb hdd, and a 3 pin case fan and graphics card. I unplugged the atx socket and the fans started whirring as if it works, but without the atx there's no point lol. But that's only when nothing else is plugged in and just the mother board. So I plug in the dvd drive and hdd without the atx and it doesn't work again, so I unplug the dvd drive and only then does it work again, so basically my psu isn't outputting enough power, is that what anyone else would say?
These are components and exact identical mobo to the one in a previous fully built pc but cause the mobo had a fault I got a new one. So why doesn't the psu give out enough power now? if it did before. Also I have replaced the hs and fan however and this one is gigantic! Do you think it uses more power? Anyway any advice or views would be appreciated. Cheers.
shouldn't be shorting out, as I said the fans work when the atx plug is unplugged and the dvd drive unplugged. One more thing, any way to test if the mother board is faulty? apart from using another one?
is there a difference between normal atx and atx 2? do you know if my processor uses atx 2? jeez i'm all confused lol. All I know is that my current one has a four pin connector to put power to the cpu, but i dunno if the one i ordered has that connector.
