Help with XFX P1-650X-CAH9 650W

post #1 of 4
Thread Starter 
Hello everyone,
Hope it's ok for a new user like me to post. I've had the above power supply sitting brand new in box for about 6 months, and I'm unsure what to do. You see, I got one in a combo deal about 7 months ago, thinking that it would be ok. Well, I received it, installed it with a new cpu, and the next thing I knew my pc wouldn't start up. Reinstalled my old corsair 450w and it still wouldn't start up. After trying many different things I concluded that my motherboard somehow got fried. The problem was that, since I got it as part of a combo deal, I could only get a replacement of that same psu; needless to say, I've been hesitant to try the replacement with my new motherboard. I've read how this psu has "issues" (low +12v or something) and then about the fan clicking and what not. Now, I'm not an expert at these kinds of things, which is why I turn to you guys: could I have been correct, and this psu is what fried my motherboard? I'm in the market for a new psu, but I don't know if I should try this one that I have sitting around which has been nothing but a waste of $60 so far

Well I dare say anything is possible, but I wouldn't say that this is very likely (your PSU frying your mobo).

First things first, when you first hooked up the PSU and your mobo and CPU and whatever, and turned it on the first time, what happened? Did you hear any sounds? Sizzling? Hissing? Popping? See any smoke? Scorch/burn marks anywhere? Smell any odors? Foul smells, funky smells, etc?

Or did nothing happen when you hit the power button? Without some physical indicator of an event occuring it's not likely the PSU "fried" anything. If nothing happened it's possible that the issue is something else (faulty ram module, DOA CPU, DOA mobo, loose power connector, almost anything really). XFX PSUs are generally quality, and while they might occasionally arrive DOA, it's far far less likely for them to immediately destroy a motherboard on hookup.

If you're really worried, and don't want to subject your current mobo to possible death, you can buy a PSU tester for like $15, it won't give you any super fine details, but if your PSU is so bad that even plugging into a motherboard instantly destroys it, it will definitely be able to tell you that.

First of all, thanks for the reply I suppose I could have been a little more specific. There were no sounds nor any signs that something was burnt (smells, marks, etc.) When I turned it on my case fans powered up, but other than that, there was no sign of life. I thought that the new cpu might have been DOA, but when I switched it back to the previous one it still wouldn't do anything. I tried reconnecting pretty much everything to no avail.
It sounds like the chances of it at least happening again (if the psu was even at fault) are slim, so I might go ahead and get a tester and try it out one more time. Thanks again!

You're welcome.

I wanna give you one last bit of suggestion before you run off though. Do you have your PC speaker hooked up? If not, hook it up!

I had a similar problem, fans spinning up but no POST. I tried everything, flashing my CMOS (you might want to try that too), reconnecting everything blah blah.

When I got my pc speaker in, the beep codes came on, and apparently one of my sticks of ram had gone bad at some point without my realizing it. Coulda saved myself a lot of grief!
