Hey guys
I recently bought a new system built around an Athlon X4 860k on a Gigabyte F2A68HM-HD2. I didn't even think before buying but this mobo has an 8pin power connector for the CPU which my rather old PSU doesn't have. I've read in lots of places that this doesn't matter that you can just hook up a 4pin connector and it'll work just fine but this absolutely does not work for me. With the 4pin connector attached the machine will turn on but won't properly post - No beeps, no graphics, not even numlock on the keyboard. The fans spin but nothing else.
My guess is that this is happening because the Athlon is an 95w CPU running on a platform typically built for 65w parts so it probably needs the additional oomph that you can only get from connecting all 8pins but I wanted to ask you guys and get some opinions.
I know I could just get another power supply but I spent my whole budget on my system and my present PSU is just fine; it's old but it's got plenty of power and replacing it just because it lacks a connector that didn't exist when it was built just kinda sucks.
I've seen adapters to go from 4pin to 8pin for the mobo connector - Do these work? I've also seen molex to 8pin mobo connectors - Do they?
Also - Is there the potential that something else is wrong with my system? I really don't want to be sending off for special adapter if they don't actually fix the problem.
I've seen other people say that the 4pin connector should totally be able to transfer enough power and that really does make me wonder if I got a bad board or something. The fact that I've tried a few PSUs including the 750w one from my gfs machine that has way more than enough power and still can't get the board to post makes me kinda uncomfortable. Especially since I bought this so I could have a Christmas break happily gaming I want to get this sorted ASAP and I definitely don't want to be spending out on parts if I still have to return the board.
Any help here would be greatly appreciated.
Edit -
Just to anticipate a question - The board is officially listed as supporting my CPU out of the box so it shouldn't need a bios update to recognize it.
