Power Supply Issue?

[ClLUTClH]

I just recently upgraded my video card from an EVGA GeForce GTX 650 1GB to an XFX RADEON R9 290 4GB. I have been having issues with my system powering down while playing games, especially with Battlefield 4. I know this card draws a lot of power but I meet the minimum power supply requirements by 150W. Here are my full specifications as of today:

• Motherboard: ASUSTeK COMPUTER INC. M5A97 LE R2.0

• CPU: AMD FX-4300 Vishera 3.8GHz (4.0GHz) Socket AM3+ 95W Quad-Core Desktop Processor

• GPU: XFX R9290AENFC Radeon R9 290 4GB 512-bit GDDR 5 CrossFireX Support Video Card

• PSU: KINGWIN ABT-650MM 650W ATX 12V v2.2 Power Supply

• Memory: Kingston HyperX XMP Blue Red Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 Desktop Memory Model KHX16C10B1RK2/16X

• Hard Drive: Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive

 I watched the temperatures while under full load and they were all fine. I'm led to believe it's my power supply causing my computer to shutdown. What else could it be?

Also, I am building a new PC a few months from now (includes the R9 290) that will look like this:

I'm 100% open to any suggestions.

My main issue is I'm not going to have the money to build my new computer until February or March, but I'd like to game until then.

Thanks!

Get a better PSU.

Maybe this one:http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095

Or buy the 1000 watt one from corsair.

I would also recommend a Corsair PSU. Never had a problem with one over the years.
