Is my power supply going bad? Please, need help and fast.

Hey there everyone.

I have a practically NEW system at this point.
December 28th, new motherboard, ram, CPU
This week, new WD HDD

The ONLY thing now that is not "new" is the power supply which I admit I bought "new" second hand, and this is what I am asking about.

Today during a render in adobe premiere pro the system locked up and windows 7 would not restart.

I have a copy of windows 8 that I tried, and after installing that things seemed okay.
except.

1. mystery restart for NO REASON after the first boot.
2. My USB powered HDD starts not working, i can hear the platters clicking (like only one USB was plugged in and not enough power)|
3. Every time I would try and render in premiere pro the system would reboot, and I am getting errors that read WHEA_UNCORRECTABLE_ERROR
Then some strange NTFS error... but the system ALWAYS reboots okay into windows 8
4. Prime95 lasts all of 30 seconds before death.

now, asus AI suite was giving me errors for SOMETHING that i could not see.. it would give an error form briefly and then dissapear.

I assumed this was some of the false errors asus AI suite has a tendency to give.

Now I wonder if this is a power supply thing. does it sound like this to you?
Please do chime in.

I am always glad to help! From the start I didn't think this was a PSU issue.

so, am running prime95.
i will let it run overnight.

my temps in AI suite for the CPU read 51c (for CPU) and 31C (motherboard) after the first 5 minutes, and coretemp does not get past 38 degrees.

Before, the aisuite would flash that cpu was above 65 C and i assumed it was giving me a tjmax. i guess I am right to say it was NOT the tjmax.
Coretemp gave me the 65-67 reading and that was probably going to KILL my pc.

So another few minutes and ai suite reading 52c. Coretemp 38.

are these okay ranges?

Anything below 60c for that CPU is fine. 52C is great! I'm glad we could get this sorted out.

You can disregard motherboard temps as they aren't a thing to be concerned with.
