Look for a OCZ and chose a modular model. Look at the 12+ volt amperage needed by the 470 and chose a PSU that can support that need. You might consider the EVGA NVIDIA 460 1GB with External Exhaust to help deal with the heat being generated by a high wattage video card.

Thanks for the link, I found this one rated for 40A and the GTX 470 requires 38:
Looks like a pretty good PSU.

Thanks for the help. I know the OCZs were cheaper but the reviews on this unit are good.
With a serious card like this hopefully I can just upgrade to the best processor this board can use (Q9650) and 8GB of DDR3 RAM next year and be good for a few years again.

A bit of caution. Your new potential video card and PSU is going to generate more heat so be prepared to deal with that issue. I typically like to see lower wattage video cards in the smallish HP mini-towers as heat has a tendency to shorten the life of the electronic components.

I just bought a HP Pavilion Elite HPE-300z series. Just like most here, I want to upgrade the PSU because I also want to put a better video card in. Will I have a problem fiting the following PSU and Video card in the HPE-300z case?

The best thing to do is to open open up your PC and do some measuring. The 460 length wise should fit but it's a double wide card so the slot next adjacent to the PCI-E x16 needs to be open.
You might run into a heat issue with the smallish HP mini-tower cabinet so be prepared to deal with it.
Otherwise, good choices.

Thanks, I haven't received the computer yet, but thanks for getting back to me. Happy to hear that I shouldn't have any problems fitting the PSU and the video card. As for the heat issue, anybody else have experience with this setup and heat?
