Hello all, my brother and I recently built his computer and we are thinking of maybe selling it, but want to upgrade it a little before we try to do so. So this is the build as is:
Case: BitFenix Comrade
Mobo: Gigabyte GA-Z87M-D3H
Processor: Intel Core i3 4130 3.4 Ghz 3MB
Graphics card: Asus Radeon R7 240 2GB
RAM: Kingston HyperX Blu 4GB DDR3-1600Mhz
PSU: ThermalTake TR2 500W
Fan: BitFenix 120mm Spectre LED Fan x2+stock fan
HDD's: Seagate Barracuda 7200rpm 64mb x2(one 1TB, one 320GB)
We were just wondering with the current specs if we added another RAM chip another fan(the second aftermarket fan is not in the build or bought as of yet) and another Radeon graphics card as it is supported by the mobo, if we would need a larger PSU? I'am thinking we will but not sure and if so what wattage would be appropriate?
 


A good quality 550 will be enough. The CX600m is sufficient but it is a budget psu.
A XFX TS 550W would be a better choice - http://pcpartpicker.com/part/xfx-power-supply-xfxts550w

In my local area there aren't any stores that carry the XFX TS 550W PSU and in my area the CX600m is a little more expensive than I think my brother wants to spend, so would the ThermalTake TR2 600W Power supply do the job?
