Just Installed New CPU and Motherboard and Computer is Crashing Every Couple Hours

Here's my new build: http://pcpartpicker.com/user/Quintonimor/saved/RgNLrH

Here's my old build(It doesn't show what cooler I was using on the old build, but it was just the standard Intel cooler that came with the i3 processor): http://pcpartpicker.com/list/Jt6cTH

The computer works very smoothly most of the time, but it occasionally shuts down. When I say shut down, I mean that it shuts down in like 1 second, as if it had been unplugged or something. I've been told here on Tom's Hardware that I need to replace my power supply. But PC Part Picker is indicating that my power supply is enough watts. Also, I went to store that sells computer parts and asked a bunch of questions and they told me that, among other things, my power supply was more than enough Watts for my build. But that was before I replaced the motherboard and CPU. This was my first time ever replacing a motherboard and CPU, but I spent the entire day before watching youtube videos and reading the manuals that came with my motherboard and CPU. It may also be relevant that I replaced my CPU cooler, too. There don't seem to be any other noticeable differences besides it being faster. If it is the power supply, feel free to suggest a new one that would work with my build.

This the nameplate on your PSU?

If so, it is a cheap ripoff of a 575W unit. The +12V rail (the one that does all the heavy work) is only rated for 25 amp. There are decent 300W units that are stronger than that. I'd suggest replacing it no matter what. And it might just solve your problem along the way.

What's your budget for a new PSU?

one of two things is wrong with your pc:

1. Your cpu is overheating and shutting off to prevent damage (did you make sure to apply thermal paste properly?)

2. Your power supply is not providing enough stable power and it is causing your pc to crash.

My bet is on the latter, Logysis is a company known to make crappy power supplies that often don't provide as much power as they say on the box. I'd say the best course of action is to remove the cpu cooler, reapply the thermal paste and then try to run an intense program while monitoring the temperatures, if they exceed 80C you probably have an overheating problem. If the temperatures stay below that then its definitely your crappy power supply.

If you get a new power supply, do some research and make sure its from a reputable company like EVGA, Corsair, Antec, Seasonic etc.

Well, the Logisys PSU is a real cheapie. Not very good and definetly not up to its ratings. But if it worked with the i3 and old 9800 GT, it should work with the i5 and 9800 GT. Unless the extra watts the i5 consumes is too much for it. My first hunch (assuming you did everything right on the assembly) is the PSU.
