I recently upgraded my GPU to GeForce GTX 660 the min power requirements on the box calls for a 450W psu... my Dell XPS 420 only has a 375W psu. Now what is happening is as I'm playing Diablo 3 about 5- 10 minutes into the game the system shutsdown and then restarts. I used driver booster to make sure all my drivers were up to date. Also one of the two fans on the GPU is pretty much completely blocked. Do I need a new psu?

Update 1/12/14: I checked the windows event log - there were three critical system errors that coincided with the times I was playing the game. One of the reasons given for the shutdown was sudden loss of power. I think it is obvious I need to upgrade my psu - I guess the only question left is how do I get the best value for my dollar?

Buy a couple cans of compressed air and get an old tooth brush to clean up ALL fans and dust...... (unplug the computer, be Careful....)

Dell power supplies won't work. Buy a 500watt Corsair CX500......... (or CX600 if you can afford it)

I would prefer XFX 550 PRO for PSU, better than CX series of Corsair. But do your case/cabinet have enough room to fit a standard ATX PSU, first make that sure, then think of buying a PSU.

And try to clean your system from dust.

There is very little dust, the fan is being blocked by big plastic piece that is part of another cooling system

It works fine on my end. I'm using IE. If you get it to open, let me know what you think.

Nope that's not a decent PSU, as I said earlier go with XFX 550 PRO a solid unit and best value for your $$.
