I recently purchased a corsair cx550m refurbished from amazon (I had to use amazon instead of newegg because of a gift card) and when I plug in everything, the motherboard doesn't get power. I was getting frustrated with this problem after trying many different tests to make sure something else wasn't short circuited, but it turns out that I have to bump the power supply in order for it to start working. It only happens when you plug in the power supply from the wall to turn on the mobo's led, but after that It works flawlessly. Why does it need to be bumped to get power to the motherboard and how can I fix it / return it if I can?
 
Solution
If it was returned to them, and they connected it up on their test bed and it ran and passed all tests, it would get sent back out. Perhaps THEY bumped it as well while setting it up and didn't see that it had any issues. It's unlikely they would test it, power it off, then test it again. Lot's of reasons WHY something could make it through a return and end up back in somebody's hands, but it really doesn't matter since you DO have problems with it.
Return it. Immediately. This is probably exactly why it was returned and then resold as refurbished, when it probably wasn't refurbished just reboxed, in the first place. There is no logical reason for why you would have to do that unless, and I'd double check, one of the plugs isn't completely seated at the PSU end of the cable OR on the motherboard. If the cables are solid, fully seated, and I might also UNPLUG them and make sure there are no bent pins on any of the connectors, then there is something loose inside the unit that bumping is just enough to overcome.

It will get worse, not better.
 


I got it refurbished from corsair through amazon so I don't see why it wouldn't work, but it is probably a good decision to return it.
