Replacing a PSU

I have an HP Pavillion that only has a 350 watt PSU. I would to upgrade my graphics card to an ATI 1800xt but it says you need atleast a 450 watt. I found a 600 watt REALLY cheap with MIR. I was just wondering how hard it is to replace the PSU? Could it be as simple as just replacing the PSU and just plug the old chords into the new PSU? Thanks.
 
Be careful of "really cheap" psu's...what brand and model is it? You don't have to spend a lot to get a good power supply but its important to do some research, narrow your choices to a few models and then comparison shop.

edit- you also need to find out if your HP case will accept a standard ATX psu.
 
Some HP Desktops also use different mobo/PSU standards for connections, and if your does then replacing your PSU could fry the mobo and CPU.
 
I don't think HP is Propriatory.

First: Make sure your pc has PCI-E. Really. Lots of pc's still don't have these.

Then try a power supply that's shorter length. Or, you can ghetto rig it duct-tape style. Or something like a Seventeam 500w external psu which you mount on top of the pc.

I used to have one, and I blew the mobo with a different PSU than the one that it came with. I think it was purchased in 2002.

Well, according to PC P&C's site HP's use the same plugs as the industry standard and speaking from personal experience I've massaged over a dozen HP cases to fit full ATX PSUs and never, ever had an issue with the PSU killing anything.
 
i 2nd BBq on checking if ur mobo supports PCI-E VC before changing psu's.
it's e-z to change psu's. there are only 4 screws at the back that hold them to the case. of course disconnect all connectors first.
