Hello all

In a bout of upgradeitis I purchased this graphics card:

http://overclockers.co.uk/showproduct.php?prodid=GX-022-ZT

I was going to get an ATI HD 4670 because they don't use much power, but then I saw the Nvidia which also purportedly doesn't need much power. I'm upgrading from an 8500gt so thought it would be sensible to stick with Nvidia.

I've installed the card, the fan spins round, but it's not showing up under Device Manager.

Is this because I only have a 300w psu? I suspect it is, but would appreciate confirmation. The documentation with the card recommends 400w but I wasn't sure it this was exaggerated.

Many thanks

Jim

I would not have thought you'd have a hope of kicking that into life with a 300W PSU. Thats not even enough to start most machines, let alone a GPU

Go get yourself one of at least 500W - you should be able to find one for under 15
But just check that
1) that the card is actually properly seated in teh motherboard
2) that you've not forgotten / missed any power connectors on the card (I don't know if that card has one, but check it just in case)

Thanks!

Yes I thought it must be the PSU. The thing that threw me was the fact that it wasn't even detected, but I suppose if there's not enough power going through it, then it wouldn't be, would it?

Back to the shops then!

Cheers.

precisely
I've had the same problem int eh past with other cards - one particular pain was a 512MB Radeon 9600 which needed a 550W to kick it into life
