Hello everyone and thanks for reading. Just built a computer (here is the part list) except I returned the CPU cooler as it turned out not to be compatible and got This power supply instead.

Here is the issue; Every now and then (very randomly but at least once every 15 minutes) the computer will reboot. There is no warning sign, all of a sudden the computer will just be restarting (or it will freeze til I restart it). The screen that says that the computer was not shutdown correctly appears and then I usually pick "start windows normally" (or whatever). Windows 7 installed correctly and the problem happened even before it was installed while setting up the Bios. When the computer does run though, it runs great. Also the bios said the CPU was running at 54 degrees Fahrenheit while just on the bios not doing anything.

Please help?

The OP said that they got the Corsair TX850M instead of the OCZ550FTY.

It's definitely not lack of power but that still doesn't rule out a possibly defective power supply unit.

The 54°F / 12.2°C CPU temperature reading in the BIOS seems improbable for an air cooled CPU. Are you using the latest motherboard BIOS Version (i.e. 2.40)?

Have you run any memory diagnostic tool like the freeware MemTest86?

My first instinct when I hear "turning off randomly" is a faulty PSU. OCZ products in general are very mediocre and the Fatal1ty is no exception. If I were you I'd test that rig with a different PSU from a more reputable manufacturer such as Seasonic, or one from a rebrander which use reputable OEMs such as Antec, Corsair, or XFX.

For a system using a single GeForce GTX 650 Ti BOOST graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

For a system using two GeForce GTX 650 Ti BOOST graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 33 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

There is really no need for an 850 Watt PSU for your system configuration. You could have saved some money and gotten a Seasonic G Series SSR-550RM.

54 degrees Fahrenheit was a typo, its 54 degrees Celsius my bad!

ko888, what are you saying? is the power supply inadequate? I'm really new at all this stuff and am very confused.

i bought the power supply on the part list posted above (550w fatality) and it did not work at all.
The fans wouldn't even spin. I returned that one and got the 850 I have now. Could the motherboard be at fault? Also I'm pretty sure I updated successfully to the latest bios but who knows what's going on in there. I'll try the ram test.

Thanks!

The Corsair TX850M is way more than you require. What I'm saying is that you could have bought a higher quality 550W power supply for less money than the Corsair TX850M.

Safe CPU temperatures are 62.5°C and below. It may still run fine with CPU temperatures, exceeding 62.5°C threshold by a few degrees. Running the FX-6300 close to 70°C and higher is not recommended.

Your idle temperature of 54°C is too high. I would only expect it to get that high under a heavy processing load. Are you sure you have the CPU cooler mounted properly after cleaning and reapplying the thermal compound?

I've ordered thermal paste and it should be here tomorrow or monday (it came with some already applied but I decided to go ahead and put a litlle more). Do you think that could be the reason it reboots every 5 minutes? or do you think the powersupply is at fault for the rebooting? I'm going to go ahead and return it anyways to rule it out completely. I really have no clue what's going on and am desperate to figure it out

Your very high idle temperature points to a thermal problem and that usually leads to eventual system lockups and reboots.

so... what do I need to do? Keep in mind the computer was built 2 days ago and that it's never worked correctly. Do i need to get a cpu fan? or a different processor?

You need a CPU cooler that actually works.

You said you returned the Cooler Master Hyper 212 Plus because it was incompatible. How was it incompatible? Cooler Master claims compatibility with your motherboard's AM3+ socket.
