On a similar subject, I've just bought a Radeon HD 4770, which requires a 450W PSU, which I thought I had but turns out that it's only 400w (and not a very good one either).
The computer will POST, make it to the Windows XP screen then cuts out (everything is still powered but won't make it to the Welcome screen) - am I safe to assume that I just require a new 450+W PSU?
