CPU has a TDP of 95W
R9 280 has a TDP of 250W
Allow 40W for other components
95W + 250W + 40W = 385W
Most of this is on the +12V rail, so approximately 32A.
To stay under 80% of the +12V rating, you want a supply with a +12V rating of 41A.
The CX430M is rated at 32A on the +12V rail.
I would not turn this machine on with that power supply. It would run at the absolute limit of the rated specifications and it is not a great power supply to start with.
You want a good supply at least 500W, preferably more.
Here are some suggestions:
XFX Pro 550
XFX TS 550
Any other 550W XFX supply
Antec HCG 620 or 620M
Rosewill Capstone 550
Corsair TX 550M
