Solved. For future reference:
It was a driver issue. By setting the GPU priority in BIOS to use on-board video instead of PCI-E, even if there's a pci-e card in there, I was able to install the OS. Once in the OS, it was easy to install the proper drivers for the radeon card. After reverting the BIOS settings, I was able to boot up using my graphics card in the new setup.
Thanks for all the replies everyone. Guess I kind of threw you guys off by suspecting my PSU, which turned out to be more than capable of powering the system under a high load.

Original question:
Hi all,
Some time ago my graphics card died, and I got a fairly low budget new one. An asus radeon hd 6670. This ran stable in my old setup (asus p5ld2 mobo, some old intel c2d 2.4ghz). Having got that, I figured I might as well give my computer a little make-over and refresh a few parts. To start it off, I bought:
- Mobo: Asrock B75 Pro3-M (Micro atx)
- CPU: Intel Core i3 2130 (S1155)
- Corsair 8GB DDR3 memory (1 stick)
- WD 500gig black series hdd, sata600 @ 7200rpm
After having set it all up, I found that I don't have the power supply connector to put in the 'ATX12V1' slot, an 8 pin slot. (2x4) If I leave it empty, it won't boot. If I put in the 4 pin connector (2x2) it boots up, seemingly fine.
Here's the tricky part. When I insert my graphics card (radeon 6670), I get no video. Not on the card itself, and not on the onboard video.
I'm somehow getting the feeling I might be underpowered, but I'm not sure and would rather know before spending a bunch of money on a PSU.
The used power supply is: X-Gear 450w unit. It's fairly old... like, at least six years old. I'm guessing thats the reason I dont have the (fancy) 8 pin connector.
Any feedback would be much appreciated! I'd hate to miss my raid night tomorrow night, or have to go back to my old crappy setup temporarily.
PS. I know the parts I bought should work fine together, as I followed one of the 'best buy guides' for one of the biggest dutch tech websites. (Tweakers)
