I'm going to buy a video card - the ASUS R9280X-DC2T-3GD5 to be specific. Based on what I see on youtube, this requires a 6 pin and 8 pin power connection. I've checked the cables in my PC case and I have lots of 4 pins and some 6 pins, but no 8 pins. Can I use some sort of adapter, eg. two 4-pins + adapter = 8 pin?

I'm using a P6T case with 500W power supply.

Thanks!

What make and model supply?

A Radeon R9-280X needs 30 amps on the 12v rail and a 550 power supply with 1 - 6pin and 1 - 8 pin PCIE power connection.

Thanks! I just checked and although I have 6 pin connectors, I don't appear to have any 2 pin connectors (at least, not any spare ones?). Perhaps an adapter is required after all?

You da man Blackbird! Unfortunately I have traced every wire in my computer and I still can't find a 2 pin connector. Lots of 4 pins and some 6 pins, but no 2 pins. :( I guess I really will have to buy an adapter of some sort.

strange indeed, but it's definitely not there. perhaps the computer store that put it together for me used a different wiring harness?

So if I really don't have that 2 prong adapter, can I just plug the 6 pin adapter in and it'll work?

Drat. Ok so will I be okay to get (for example) a 4 to 2-pin adapter, so it'd be powered with 6pin + 6pin + 2pin? Or do I have to buy a whole new setup to get this card working?
