Separate PSU for a New GPU

[TheSRQPilot]

So here's the story I bought a Dell XPS 8300 with an I7-2600, 8GB Ram, a Gt 530 GPU, and here's the best part... a 450 Watt PSU
I need to power Gtx 560ti because I can't do that with a 450 watt PSU.
Would it be easier to get a Corsair 850 watt PSU and switch it out? Or get an external PSU, and power it with the second PSU? Any thoughts would be great. Thanks

I think a good 550W would do but I'm quite sure you don't need an 850W PSU to power that PC...

im going to go with a 750 because I might want to do a sli and/or add a capture card if there is room.

Do you think I can switch it out or will I have problems since its a OEM comp?

i want a psu under 175 which is more than enough for a good psu, I would like to get a corsair

For dual 560 Ti SLI, a 42a, 700w PSU would suffice.

Thermaltake, OCZ, Enermax and XFX are all brands to consider as well. Just check the warranty on each and pick one that suits your needs whilst being a good price
