My build:
AMD FX 8320 (not OC) CPU
Gigabyte 970A-UD3P Motherboard
8GBG (2x4) DDR3 1600 RAM by G.Skill
MSI Radeon R9 270 (not OC) Video Card
Seagate Barracuda 1 TB Hard Drive
No CD Drive

I bought the corsair cx430m which was on sale at the moment. But I dont know if that would be enough? And the corsair cx500m costs the same now. Also thermaltake have tr2 600W on sale for $30 (after rebate) but I heard some issues with that.

All feedback is much appreciated

430 and 500watts is not enough,you need 600w or 700w psu to power your radeon R9 and the entire system

But the website you provided says that the recommended wattage needed is 450W for r9 270 (not cf). So why did u say i need 600w or 700w and not 500w

the website you provided shows that r9 270 (not cf) needs 450W. is that just for the gpu right?

yes it is for gpu only so you need more wattage for your other components,600watts is enough if you're not going to oc your gpu and cpu

The website says its for the whole syste. Here "The “Recommended PSU Wattage” value is for the whole system, not only for the graphics card/s."

Yeah using this PSU calculator: http://www.thermaltake.outervision.com/index.jsp it says that your setup at 90% utilization would draw 373W. That may be pushing a 430W PSU slightly but the corsair is pretty decent. I would go with the 500W if you can just to be safe and leave a little room for overclocking and upgrades.

The R9 270 itself only requires 150w to power it and the FX-8320 only takes 125w, them two equaling 275w. Your other components all in all will come to about 110, but I'd personally call it 150 just to be safe, making the total at about 425w.
In conclusion, you could in theory take a 430w PSU, but I wouldn't, I'd take the Corsair CX500W just to be safe.
