I need to upgrade the power supply for my computer in order to use the Graphics Card I have in mind. The only one I can find that meets the 400w requirement seems really expensive. Can anyone recommend a different PSU or even graphics card. Computer is an HP s5650z and the card I have in mind is the GTX 750Ti 2GB Low Profile.
 
Be careful with small HPs .Some of them have a 16x Pcie slot that only supplies 25W. This is a little known PCIe "server" spec. that HP used in some of it's SFF desktops. Check you owners manual and be sure. These business machines were intended for 2D cards only. I worked on one that said it supported 3 GPUs. 1-PCIe 16x 25W, and 2-PCIe 1x 10W.

Thank you both for the advice! william p, that's determined by motherboard right? I don't see that info...the motherboard is an Alvorix-GL8E. Where should I be looking?

This is the page for pc:

I looked it up by HP model# and found the users manual online. I tried to get a 27W GT630 DDR5 to run and it wouldn't boot. A friend bought one from Tiger Direct because it was cheaper than Win7 license, and her old P4 box with XP wasn't cutting it anymore. I hope yours doesn't have this. I'm all in favor of ramping up old PCs.

I have a Dell Optiplex 790 SFF with a so-called 35W restriction on the PCIe x16 slot. But I am running this GTX 750 Ti on it now using its stock 240W PSU. http://www.newegg.com/Product/Product.aspx?Item=N82E16814125680
(I'm on it now)
While I am not recommending someone else run a 60W card on a 240W PSU w/a 17A (+12v) rail like mine, the point I am making is that the slot's low wattage recommendation of slimline PCs is to avoid a card that the PSU can't handle rather than the capability of the slot itself.
