Went to install a 'new' power supply in my computer and now its dead in the water. Help??

Msi a75ma-g55
Amd 3.0 apu something I cant look up at the moment
16 GBP (2x8GB) corsair vengeance ddr3 1600
Corsair gs600


Ok so I had a fully detailed paragraph for this post at the start of my thread and then lost it all somehow and got just this? Today's being a realpain for me.

So I got a slightly used 1000w raidmax power supply today and tested it before putting it into my system. It juiced up so I went to configure it into my system. Long story short it turned on for a second then it powered down. I smelled a slight ozone smell so I immediately flipped the power and removed the psu from my computer. I put my old corsair back into it and now its doing the same thing. I've tried resetting cmos, breadboarding, checking for shorts and removing the bios battery. Nothing.

Im worried this psu fried my motherboard. I've tried looking in here for a solution but I cant seem to find any. Can anyone help??

Also I've done all the steps in the "steps to perform" thread. Im out of options here!

We can only guess until you post the complete system specs. So the system was working until you replaced the PSU? What prompted the PSU replacement? This troubleshooting checklist was created for this type of problem.

Sorry about that. Id originally had the specs and situation listed out but for some reason my phone decided not to submit them. I edited the post. I've tried everything in that list.

What prompted this was that im going to build a 2nd computer soon and need a beefier supply for the sl I gtx770 im going to run in it. So I got this one and figured I'd make sure it worked fully and use it in my computer for a few minutes to ensure it worked fully... guess this was a mistake.

Yes. The system had been running with no trouble for almost two years now.. other than my new gpu this is the first time I've modified any of the components of the system.

I've had no problems with it, run antivirus/malware every three days and im tech savvy so I know to keep myself grounded while working with the i nners of the system while swapping and installing pieces.

You most likely fried something and the only way to find out what is swapping out parts. 600W is more than enough for that system and most GPUs. Only high end SLI/crossfire setups need 1000W and you would never want to use a raidmax. they are junk

770s are only 230W cards. A good 750W PSU would have been plenty

Well eventually I'd planned on getting an I7 and a new board and figured I'd need a bit more power for it. My current processor bottlenecks my gpu right now at 1440p resolution.
