Where can I find a 4-pin PSU?

Hey guys, I have a bit of an interesting scenario.

My mother has a HP computer she bought from Costco.

For her birthday, I decided to get her a graphics card and a 2-way monitor setup, to replace her old 14 inch CRT monitor that she hates.

Well, I went to put it all together, and... the PSU doesn't have a auxiliary 8-pin.

So I went to take the PSU out of my old gaming rig, and found that it only has one 6-pin, when the adapter to an 8-pin needs two.

So I started looking online. Before I did, I measured the CPU to see it's specs (top mounted ATX) and noticed something interesting...

It's got a 4-pin cpu connector instead of an 8-pin.



So. That wall of text out of the way, here's my question:

Where can I find a decent 400-500w top mounted ATX psu with either two 6-pin or an 8-pin graphics power and a 4-pin CPU power?

Either that, or how can I take one of the power supplies I have available, and make it run both the 4-pin CPU and the 8-pin card?

Not much point in worrying about getting a "top-mount" PSU since an ATX PSU is an ATX PSU regardless of where it is mounted except that bottom-mounting tends to require longer cables.

Not much point in worrying about the 4-pin CPU power connection either since most PSUs either have a 4+4 EPS12V connector or separate 4/4+4 cables. Either way, they should both work.

As for the GPU, you didn't say what it was and unless you tossed a high-end GPU in there, it should not require that much power and run fine with a 6-pin PCIe power connection. High-power cards usually have a combination of 6pin + 8pin connection that allows people to use 2x6 or 1x8 cables.

Okay, I haven't ever seen a 4+4 connector - how do I tell from the description what connector it has?

It's just a GTS 250 - But would they include the two 6-pin to 8-pin if it didn't need it?

Newegg and other websites have good pictures. You should be able to tell if the power supply has 4 pin connectors. You don't know to worry, though. It will have an 8 pin that will separate into two four pins if needed.

If you're looking for a power supply, the description will tell you what the PCIe connectors are. It will say 8 pin PCIe or 6+2.
