PC Turning Off on demanding games

Solution
no, it's not only 190W. That's the combined output of some of your rails. Look instead for a model number to look for the specified max output, but chances are it's not going to be sufficient. A complete power down during gaming is indicative of a weak PSU.
 
I have a HKC Power Supply 650w anyways and no, im just playing bf4 and my computer all of the sudden restarts, temps are normal. CPU doesnt go over 75, GPU doesnt go over 85.
 
If the PCI-E cables aren't distributed across the two +12V rails properly or the OCP setpoint is too tight then you will get the problems that you're having.

That HKC V-Power 650W is very inefficient (~75%). Inefficient will mean that a lot of heat will be generated and that will accelerate the loss of capacity as temperature rises (i.e. derating) and as the aluminum electrolytic capacitors' electrolyte evaporates (i.e. will cause electrical noise and ripple levels to rise possibly outside of allowable ATX specs).
 


Haha I pretty much didn't understand anything but yes, I am getting a weird buzzing noise when im playing. So can you give me instructions on how I can fix this? Or is a new PSU the only way to solve the problem?

 


That buzzing noise is a pretty good indication that the PSU is struggling to put out the power that the system is demanding.

A new reputable brand PSU is the only way to fix that issue.

For a system using a single AMD Reference Design Radeon R9 280X graphics card AMD specifies a minimum of a 600 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 40 Amps or greater and have at least one 75 Watt 6-pin and one 150 Watt 8-pin PCI Express supplementary power connectors. There are some non-reference design cards that require two 150 Watt 8-pin PCI Express supplementary power connectors. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)

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) is the most critical factor.
