So i am in the midst of upgrading my pc, i have so far bought an AMD FX 6300 cpu and an ASRock 970 mobo. i am going to buy a new graphics car as well and was thinking of the Gigabyte R9 280 Overclocked 3gb which should run ok with a 650w psu but my power supply (Coolermaster Extreme Power Plus 650w) i have read is not a very good power supply, so i was just wondering if my current psu would survive running my new gear for 2 weeks until i can afford to upgrade it?
