Just bought a Studio XPS, first new desktop since the one I built in 2001. I opted for the low-end video card to knock off $200, and used part of that to buy an EVGA 9800GT (512 MB version). I threw it in, and it seems to be working fine. However, I've noticed that the PSU is 360W while the card specs say it needs a minimum of 400W. I figure there is some fudge room in the specs, but am starting to get paranoid that I may have to buy a bigger PSU. But after shelling out the money for the PC, I might have trouble convincing the wife why I need to spend another $100
So, after the long-winded backstory, what are the chances I will be ok with the stock PSU? I am only a casual gamer (Red Alert 3, Call of Duty, etc.) and wasn't trying to build a true gaming PC, just something for all-round use. I have no intention of overclocking, and will keep everything else stock and will only have 1 hard drive.
