Why does my PSU power surge?

[cheesy_iron]

So I upgraded my psu and gpu in June. Hd 5450>gtx 650ti boost. Off-brand 450W>Thermaltake tr-2 600W. Some times when I play certain games (Bf3,Arctic combat,RaceRoom Experience) all of the sudden, my whole pc just shuts down. My MB comes up with a error message saying my psu surged and my pc shut down to save the components. It just now happened again. I just spawned in a bf3 server, played for 30s then died. Respawned, ran 10ft then it shut off. My psu is rated at 23A on the 12v rail and the 650 boost needs 24A. Would this cause it to shut down? Here's my full pc:http://pcpartpicker.com/p/1ze6f

What would happen if I turned off the power surge mode on my MB? Would it totally fry all my stuff? Would this be caused by heat? I have the fan facing down sucking air in. I also have a game case propping the case up so it can get more air. Any suggestions? (sorry for grammar mistakes, i'm really tired.)

As you can see on this list, your PSU is listed as a tier 5 psu, and recommended for replacement. Very low quality build.

Do not turn off the power surge mode on your mobo.

So I can't fix it? Is this caused from not having enough amps? I know when I bought it, it was not a good psu. I thought that if I had 100w extra it wouldn't make a difference.

Poor quality unit that doesn't reach advertised power.

The TR600P is a decent unit made me FSP.

Most likely. It probably doesn't even give you 23A.

Possibly could fry everything. Definitely would fry something.

Would this be caused by heat? I have the fan facing down sucking air in. I also have a game case propping the case up so it can get more air. Any suggestions? (sorry for grammar mistakes, i'm really tired.)

No, it wouldn't be caused by heat. Also, your top/back fans should be exhaust, bottom/front should be intake.
