whats up everyone im new to the forum and also baffled as to what the hell is going on with my pc.
Basically I built a custom pc about 2 weeks ago with help from pc gaming friends, these are the specs

asus p8z77-vlx motherboard
intel core i5 3570k 3.40ghz processor
8 gigs corsair vengeance ddr3 ram
nvidia geforce gtx 560 graphics card
thermaltake TR2 RX 750watt bronze certified 80 plus power supply unit
Windows 7 64bit sp1

When I first installed everything, I ran games like crysis 1, skyrim, and the stalker games at fairly high settings. The games ran fine for hours at nominal fps..Basically everything was working fine.
After about a week into having this pc (I wasnt gaming that often, an hour or 2 every 2 or 3 days) after about 20 minutes of gaming, during the game, the screen would go black, the graphics card fan stopped and the computer remained idle and I had to reset when playing the mentioned games.
Another week later the probem got even more strange. I installed the game INVERSION(on fairly high settings), got through the menu screen, played for literally 1 minute and the shut down happened again. I thought this was awkward so I tried binary domain (also on very high settings) and the game worked for about an hour, until I stopped playing, no shutdown happened. Also with batman arkham city the game runs fine. I ran INVERSION again. put all settings to low, lowered the resolution..the game lasted maybe 5 minutes before my pc shut down.
I used to think this was a heating problem but how can my pc run some games on high settings without problems and others wont even last 5 minutes on low settings.
I read up on my PSU and read some bad reviews so im thinking maybe its a psu problem but Im a pc gaming virgin and know nothing about psu's so I thought id come here and ask before I exchanged it.
all my software is up to date and I have no viruses or spyware, I ran msi afterburner and the gpu and cpu were at normal heat levels when gaming and not gaming.

heres the quote from the review of my psu

"Thermaltake TR2 RX 750 W is, according to our methodology, a flawed product that must be avoided at all costs. It can’t deliver its labeled wattage at high temperatures, but this is not the worst of it: ripple and noise level are way above the maximum allowed when you pull 80% or more from the unit’s labeled capacity (i.e., 600 W and above), overloading your components (especially electrolytic capacitors from the motherboard and video cards), which can cause your PC to present an erratic behavior (crashes and random resets) and, under extreme conditions, damage components."

THANK YOU for your help in advance

From your post i get the impression nothing is damaged since you can run your pc fine as long as you do not run any games. A bad psu however, is not uncommon. But i have no idea about the gfx card you are using. I find a 750 watt psu a bit much but then again, i do not know anything about peak power consumption of nvida gfx cards. According to the website it is rated at 150W max and your cpu is about 80W. With all extra hardware, i would think you have enough power with a 450W psu. But i do not know enough about it. All i know is that i always by an Enermax psu when given the chance. I have never had any issues and reading the reviews, Enermax delivers quality add high efficiency. (minimal 82% at a given load.)

I think it is better you ask this question in the gfx section or psu section of the forum.
