New PSU for an HP Slimline s5510y?

[markt435]

I'm looking at upgrading the mobo for this PC and have settled on MSI 890GXM-G65. Are there any PSUs that fit that would supply plenty of watts for say, the X4 965 and an HD 57xx?

Currently it's stock with an Athlon II X2 240 and I added a 1GB HD 5450 to it. Anyone put something nicer in there or am I just dreaming?

EDIT: Scratch the vid card...whichever mainstream card there is a low profile bracket for. I think I've seen a 5600 series card on Newegg. Anything better than the 5450 lol

PSU looks like a TFX form factor... newegg has a few 300w units.

Until powercolor releases their low profile 5770 (IF they do), the sparkle GTS 250 is still the fastest low profile card available.

Edit: looks like powercolor just released a LP 5750, though it doesn't appear to have rolled out to retailers quite yet. The 5750 should be about as fast as the GTS250, but you get DX11, eyefinity etc.
