Hi everyone,

First of all I appreciate anyone who can give me a hand. My build is as follows (I've added to it a bit over the past year and a half):

Asus P8Z68-V Pro/Gen 3 Motherboard
Intel i7-2600k CPU
Corsair Force GT 120 GB SSD
2 EVGA GeForce GTX 550 Ti 1024 MB Graphics Cards
Seagate Barracuda Green 2TB HDD
16 GB Corsair Vengeance RAM
Samsung Blu-Ray Drive
Cooler Master Hyper 212 Plus
Bitfenix Recon Fan Controller
Corsair Carbide 500r
Corsair GS 700W PSU

In the case I've also replaced the 2 front stock fans, the exhaust fan and the stock fan that came with the heatsink so within the case I have 7 Aerocool Shark 120mm fans. (5 are controlled by the fan controller, the exhaust is connected to the motherboard and the heatsink fan utilizes a CPU fan pin on the motherboard even though it's a three pin)

About a month ago while I was playing Tomb Raider I started experiencing some power surges so I RMA'd my power supply. Corsair sent me a brand new PSU and everything worked fine until last week when my game shut off unexpectedly while playing Skyrim for a couple hours. When I tried to turn it back on the fans would spin but it would shut off after a few seconds and repeat. I opened up the case and replugged some of the cables in and I was able to get it started up again however when I went to shut it down the fans would keep spinning even after Windows shut down so I had to hold the power button to shut it off. Last night while trying to play Team Fortress 2 my computer shut down unexpectedly a number of times (one time I even got a pink screen and I had to shut it down manually). I've checked voltages on my ram and all my temperatures and everything seems okay.

Now I'm wondering if I don't have enough wattage for the computer anymore? Before I go and invest $200 bucks in a new PSU I would appreciate some advice!

It's very doubtful that you would need more than 700 watts to power that. It could be the power supply is failing though. I would suggest you get something like a kill-a-watt or similar device and plug it in to see, you probably aren't pulling much more than 450 from the wall, which at 85% efficient would be about 385 delivered.

They are pretty cheap devices, and it will give you an idea on where you should shoot for when buying a new supply if yours in fact is failing.

You have easily enough wattage.
Even overclocked this system shouldn't draw more than 500W.
Your PSU provides up to 58A on 12V rail and your system uses about 40A in full stress.
Check your RAM and monitor your temps. If you have any OC, return to stock clocks/voltages.

Okay I appreciate the insight. Maybe I will invest in a kill-a-watt. $20 bucks spent isn't too bad compared to buying a new power supply. It'd just be so crazy to think I got another faulty PSU from an RMA but it's possible
