PSU stability issue? (Seasonic SS-760XP2)

I got my Seasonic SS-760XP2 almost a month ago, and it's been good for the most part. My system has randomly rebooted about four or five times since I've gotten it, but I was never sure if I should attribute that to the PSU or something else. Today, my system completely shut off and would not reboot. I connected it to my old PSU (Corsair TX750) and it booted normally. Then, when I tried my Seasonic again, my system booted up normally.

I'm mainly concerned because I have two days left on my return policy and I'm not sure if it's a problem with the Seasonic, or just a random issue? I'm not sure how to test to see which it is, either.

Any help would be greatly appreciated. Thanks in advance.

The rest of my specs, just in case:
MSI Z77A-G45
i5 3570K
12gb G.Skill Ripjaw
GTX 760 2GB
120gb OCZ Agility 3
1tb WD Caviar Black
 
Not really anyway to just say it's the PSU. It could be a variety of components. Any errors in the system log?

12GB of RAM, I'm assuming that's 3 sticks which is a little abnormal for this platform. Maybe test the RAM out too with memtest86. Also test the CPU with Prime95 and monitor temperatures.
