Should do fine. The rest of your PC is not very demanding, so I'd say that it probably only eats up about 150W at full steam (that is, the fans, the hard drives, motherboard functions, RAM, CPU) cumulatively. The R7 250X, the higher-performing and therefore more power hungry of the two has a TDP (basically max power usage) of 95W. You'll have a buffer of about 200W. That's a great thing to have to level power supply aging and power spikes.

Should probably get at least another 2GB of RAM though. 8GB would be great.

Frontech is not even listed on http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html. You should get a psu friom tiers 1, 2a or 2b.

For a r7 250x you need at least 430W to run the PC. eg Seasonic 520, XFX 550 or Antec HCG 520
