Power supply for non-standard setup

Hi all,

I'm replacing an ancient PC with a HP Compaq 8200 Elite I've picked up cheaply & I separately acquired a 2GB MSI GTX 670 (probably overkill for what I'll use it for & system bottlenecks, but it was cheap).

As the fitted PSU is only 320W I realise I need to upgrade the power supply (not to mention I need 2x 6-pin PCIe connectors for the GPU). However, I found that the mobo is non-standard (see here), which seems to limit my options somewhat.

I've seen in some older threads about either separate GPU PSU's that can be mounted in a 5.25" bay or used externally, but the specific products all seem to be obsolete.

As I'm a little unsure what my best course of action is, any suggestions would be much appreciated - many thanks in advance.

(To clarify, the images below show the only connections from the PSU - in the 2nd image it's the two white connectors, the black connectors on the left are then the power to the SATA devices, there are no SATA connectors from the PSU itself)

The strategy of buying a used pre-built then adding a videocard to make it a gaming computer is a good one, with a couple of caveats. First, pre-builts worth buying are the ones in standard sized cases with standard components. If, for example, a model of computer comes in mini tower, slim form factor, and desktop, you want only the mini tower. Odd ball sizes are where you'll run into problems. The other thing is power. Pre-builts usually come with the minimum wattage power supply that the manufacturer could get away with. This almost always means any gaming card you're getting is also going to require you to upgrade the power supply. You can't do that with an oddball sized computer. Research these things before you spend money.

If I was you in this case I'd sell the 670 and use the money to buy a card that does not require a 6 pin connector and that will work with the power supply you already have.
