No don't get cheap branded psu's that will probably cause your system to become unstable and give up in a few months time. Get a branded 550W psu like corsair,antec,xfx,seasonic. The xfx 550W core edition should be fine for your system

Honestly I never heard of that psu and there's not much information about them on the internet so I recommend you stay away from it.

The minimum requirement for a r9 270x is 500W with a minimum of 30amps on the 12 volt rails with 2 six pin pci power connectors, so you should check if your psu meets those requirements

If you have about $60, heres the xfx psu I was talking about, http://. Its a high efficiency psu that delivers clean continuous power and is made by seasonic
