I have a 350W psu in my Dell Studio XPS and I'm wondering if that is sufficient to run a Sapphire Radeon HD7770 Ghz edition graphics card? Or if there is a better graphics card for a similar cost that is compatible with my pc?

Thanks
Harry

AMD recommend that you have a PSU with a wattage of 400w minimum. However it should be fine as people say AMD only say 400w minimum as they dont want people writting support tickets on there help desk system.

The big question is does it have a PCI-E power connector for the card?

How would I know if it has the power connector? It currently runs on a GTS 240 card which looks like its connected with a 6-pin cable....

have a look in side you case and if it is a 4 +2 pin connector then it will support the Sapphire Radeon HD7770

It's hard to get to the connector and see closely, but it has 3 black and 3 yellow wires connected to it which I imagine is the PCI connector?

Yes you can use that GPU with that PSU but in all honestly I would be safe and get a better PSU, if you use that PSU with that GPU and your system go cahoots then *oh dear* you have a big problem, it is a matter of paying £20 extra instead of paying for an entire system.

Okay yeah I was considering upgrading my PSU too. Also how does this gpu compare to a superclocked 650??

A super clocked 650 is much better. Get A 500W PSU.

Really? A 1Gb? Because it's quite a bit cheaper and didn't come out as well on a comparison I did. And it doesn't require as much power... apparently

Yep the GTX 650 superclocked performs better but for power efficiency the 7770 is more efficient.
