Random CPU shutdowns.

Problem description: I have recently built a new Haswell rig and facing random shutdowns on a fresh copy of Windows 7 Ultimate 64bit. It has occurred 3 times since installation. It just crashes randomly, sometimes idling or during light web browsing, sometimes when in games or watching avi files. Here is an event viewer screenshot: http://i.imgur.com/Au3KRVE.png. I am suspecting a PSU or heating issue. But I'm not sure which. Am kinda bummed out considering everything is new and I did drop a decent amount of money into the machine.

Attempted fixes: I have checked and monitored temperatures and everything appear to be a-ok. See: http://i.imgur.com/TAjz3IA.png. I have also run MemTest for 2-3hours to verify that the ram is working fine. I also ran Aida64 stability test and the Haswell chip temps shot up to 90~ degrees after 1min of testing, is this normal? Also ran CrystalDiskInfo to check drives health, and everything looks normal.

Edit: I have checked the Intel stock cooler, and it is pretty snug, also removed the side panel behind the mobo to check whether the 4 plastic pins are properly inserted into the holes. I am running a Corsair 200R casing, with 1 stock intake fan at the front, 1 stock rear exhaust and 1 Antec 120mm fan exhaust at the top.

Recent changes: It's a pretty new machine, so probably latest drivers, etc.

The main reason probably is PSU ~
Based on your given spec, that is pushing your PSU too far ~
I think u better get a higher watt and better quality PSU for the job ~

I'm going to disagree with Viper here, you have plenty of power for your build (my off hand estimate of your power draw is about 350 - 400W) but that does not mean that the SeaSonic unit isn't faulty (it happens even with the best of manufacturers) which seems to be the case here. Ill recommend contacting the retailer or SeaSonic about RMA for the PSU

Might be this, but I am kinda worried about the CPU TEMPS. Running HWMONITOR, the idle temp is currently 44C-48C~ Is this normal?

It seems a little on the high side but not so much that I would be worried - you might check your CPU heat sink mounting just to be sure it's firmly attached at all points
