Did I buy a dud?

So I recently (couple days ago) bought a new motherboard (MSI Z97 Gaming 5) and processor (i5 4690k) because I thought my old motherboard (ASRock Z77 Pro3) blew a capacitor or something. Come to find out it was my old PSU (OCZ 700W) that was the bad guy, so I replaced it with a Corsair CX750M. Hooked everything back up, made the case look all pretty and uncluttered, and everything was good to go...for about 12 hours. I came home from the gym last night, went to turn it on, and got nothing. Ok, I lied. My top case fan spun about 1/4" but that's it. I tried other plugs and power cables but I got nothing from that either. Monitor and speakers are hooked up to the same power strip as the PSU was but those are both fine.

Any idea? I didn't get into OC'ing the new chip yet so nothing crazy went on there. I'm at a loss. Only thing I can think is that I got a bad PSU from the factory.

could be the PSU, it also could be caused by failed connections to the motherboard so make sure you check that, also a fail to boot could be a problem with the BIOS but that usually comes on more than you've explained, you may have a fault Mobo as well try it with another Mobo if you got one sitting about if not ask for a replacement on the PSU

I unplugged and replugged all connections before removing the "new" PSU last night to check if it was a seating problem but again, zero response. No fans spinning, power light, nothing. Can't do anything with the BIOS since I can't boot it. Reset the CMOS and battery also.

PSU is in my car waiting for me to get out of work so I can take it back to from whence I got it. Trading it in for a more powerful one, just in case. Probably a Thermaltake 850W. Depends on what they have.

Thanks for the info and quick response though!

No problem if I was to recommend a new PSU try going for a Cossair RN series 80+ Gold if you can get your hands on them, some of the best PSU ive ever used/tested, and by the sounds of it you're not silly and more than likely it could be as simple as a Burnt out PSU, get the new one try and get a 80+ Gold or 80+ Bronze at minimum some of the best people are cooler Master or Cossair either one of these brands have done me well if it dosent work comment on this again and ill get back to you asap

Well I just looked at Newegg and they have the Corsair RM1000W for $149, same price as the 850W lol, so I think I'll go with that one. Kinda silly not to. My local stores don't carry the RM's, any Coolermaster, and very few PSU's period. I have a Micro Center about an hour away, but they have the 850W priced at $169. I can put next day shipping on Newegg and still get the 1000W cheaper.

Thanks again, and hopefully I won't have to ask any more questions on the subject .
