I built my computer not long ago. While playing more intensive games like Dirty Rally or Far Cry 3, my CPU's temp is about 59-64, and my GPU's temp is about 65-71. So it can't be either of them overheating and shutting down my computer.
My specs are:

Motherboard: ASUS M5A78L-M/USB3 AM3+ AMD 760G + SB710 USB 3.0 HDMI uATX AMD Motherboard

CPU: AMD FX-6300 Vishera 6-Core 3.5GHz (4.1GHz Turbo) Socket AM3+ 95W FD6300WMHKBOX Desktop Processor

RAM: CORSAIR Vengeance Pro 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model CMY16GX3M2A2400C11

GPU: PowerColor TurboDuo Radeon R9 280X AXR9 280X 3GBD5-T2DHV2E/OC 3GB 384-Bit GDDR5 PCI Express 3.0 HDCP Ready CrossFireX Support ATX OC V2 Video Card

PSU: CORSAIR CX series CX600 600W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

HDD: Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive

Case: NZXT Source 210 S210-002 White w/Black Front Trim “Aluminum Brush / Plastic” ATX Mid Tower Computer Case

Fans: Corsair 120mm Air Series- 2 on top as exhaust, 1 on the front and one on the side as intake (directly aimed at GPU), and one stock fan on top/back as exhaust


PS: The software I'm using to detect temperatures is "Open Hardware Monitor", and also I have tried "Core Temp".

AS long as you are willing to spend that much, spend a few dollars more and get this XFX 650W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014

The 600B is probably in the same category as the CX, but with better caps. Still, 600W is kind of marginal.

It most likely your PSU. Your PC needs more power than the psu can supply. Also that PSU isn't really the greatest. It says 600 watts but you lose about 60 watts because of the level.

What do you mean you lose about 60 watts because of the level? If you are talking about efficiency you don't lose power. For example your PSU is 600w and is 90% efficent at max load, to deliver 600w to the computer you pull 600w+10% from the wall, that other 10% is lost as heat during the conversion from 120v to 12v ,5v 3.3v.

While that PSU isn't the best in theory it should be enough although quality is a bit low. As you said temp look normal so I am inclined to believe it is a problem with the power supply and reaching its output levels.

Even if PC Part Picker says I only need 443, 600 won't be sufficient? Also I'm not overclocking the CPU or GPU. How should I go about returning it? Is there anyway to get my money back?

It depends where you got it. If the place is reputable, they will accept a return if you are not satisfied. Especially if you are replacing it with another.

Total wattage doesn't mean all that much. It is the current carrying capacity of the +12V rail(s) along with the total wattage those rails will handle. That combined with the QUALITY of the unit is what counts.

I also read that the 750W requirement is for crossfire. http://www.tomshardware.com/answers/id-1834929/280x-psu...

Should I just try a replacement of the same PSU?

Ya I might have to go with that. Now I just have to go about getting a refund for my current PSU. Thank you for the help.
