Need to PSU Help!

So PSU's aren't my specialty but, my new rig which i just replaced the mobo, video card, and ram is turning off every once in a while on its' own. I've narrowed it down to my 6 year old power supply. Its a 750 watt thermal take tough power with 4 12v rails at 18 amps each. My mobo is a 768 with a gtx 570, and a core i5 2500k. Should I buy a new power supply? If so, can someone research a good power supply thats decent and is NOT more then I need (preferably thermal take as the connectors will be similar to what I have). Thanks!!

I reckon it'll still work well with his system.

[QUOTE="04dcarraher"][QUOTE="MxAa"] THanks, but is my power supply crap for the hardware these days? I don't really know my self because 4 12 v rails seems like it would just add the amps up to a total.GS550L

The computer has been shutting off then turning back on.... it does this every once in a while. My guess is the power supply safety feature for multiple rails is kicking in. The power supply is 6 years old... maybe I should just replace it? I'm assuming 1 12v rail psus are the way to go?

[QUOTE="04dcarraher"] The only problem with multi railed psu is that "you" have to distribute the loads on the lines. 04dcarraher

If the power supply the TC is referring to is the modular TT 750W I'm thinking of, rail distribution shouldn't be an issue. The modular cable sockets are specific; you cannot plug in a 6-pin PCI-E or 4-pin Molex cable into the 8-pin EPS socket, so there shouldn't be any problems with overloading a specific rail.

--EDIT--

Aaaand here's another case of someone not reading the OP fully. If you've replaced the motherboard, video card, and RAM, there's a damn good chance that the power supply is to blame. Just ignore what I said earlier.

God, I wonder how I survive sometimes....

[QUOTE="04dcarraher"] The TC may have too much load on one of the lines. He should read his manual to see what rails powers pci-e power cables. MxAa

I'd just go with the supply that 04dcarraher suggested; it's pretty well priced with that promo code, and it's powerful enough to run a second GTX 570 comfortably if you feel like throwing a second one into your system. There has been a lot of debate about whether multi-rail power supplies are better than single-rail ones or vice-versa, but to be honest, I feel that it doesn't really matter at the end of the day; for the average user, the build quality and power output should really be the only deciding factors.

I bought the one listed listed above (the corsair). Plus I got free 2 day shipping with the free shop runner trial and 10 bucks off with the promo =D. Thx guys.
