I built this computer about 6 months ago, but it has been crashing after about 30 minutes of League of Legends for 2 months now. I've done some research, and it looks like the main suspect for this symptom is the power supply unit, especially because I have to manually flip the PSU off and back on before it will behave. Without further ado, here are my specs:

500W Corsair CX500 Power Supply
2GB Gigabyte Radeon R9 270X Graphics Card
AMD Athlon X4 750k CPU
MSI FM2-A75MA-E35 Motherboard
8GB Corsair Vengeance DDR3 RAM
1TB Western Digital Caviar Black Hard Drive

I dusted my hardware the other day with compressed air, but it had no effect. Now I think I'm just going to order a new power supply. What specific unit do you think is best for me? I'm not on a budget, but obviously I don't need to power New York or anything either. Thanks!

I'd recommend the XFX 450/550W for your system.
If you plan on over-clocking, pick the 550W
If you don't plan on over-clocking, pick the 450W.

The XFX pro series are manufactured by Seasonic, which is potentially the best PSU manufacturer out there.

Here are the 3 i'd recommend : http://pcpartpicker.com/parts/power-supply/#W=450,600&e=2&p=0&m=39

EDIT: I'd first check all of your connections from the power supply to your motherboard. A loose connection could be the problem.
