Some confusion about motherboard power connections

Hi all :)

Just starting a job at a small start up, and they asked me if I could build a few machines for the directors, myself as well as a graphic designer. Me (programmer) and the directors don't need anything fancy, but obviously the GFX designers rig has to be slightly beefier.

I'm looking at a few barebones systems, for the GFX guy in particular I'm looking at an i7 3770 based system. Problem is it only has integrated GFX, so I'll need to install a discrete card which will blow up the paltry 300w PSU that's included.

I haven't built a system for a few years, before this whole 8 pin connector was mainstream, and I'm just wanting some clarification on the whole issue. The PSU I was looking at is a 20+4 pin with a 4 pin aux ATX connector... If the board is only a 20 pin plug with an 8 pin EPS can I use the additional 4 pin lead from the main connector? Is it possible for the board to be 24 pin + 8 pin, thus leaving me 4 pins short?
For the record this is the PSU: http://www.ebuyer.com/414336-500-watt-tesla-psu-tesla-500w
...and the PC: http://www.ebuyer.com/395309-zoostorm-desktop-pc-7873-1075

Also related: I shouldn't have trouble fitting an ATX PSU in an mATX case should I? I believe mATX only refers to the motherboard dimensions right?

Cheers :)

Hi,
The board would most certainly be 24 + 4/8.
you can plug a 4 pin cable in a 8-pin connector, if not OC-ing.
The power supply has no PCIe power connectors so if the graphics card requires 1 or 2, the PSU is no good.
I would choose all components and not a barebone.
