Be warned, it's Cyberpower. They are a pretty big company, so get great deals on bulk purchases, which will include massive rebates to buy up older stock like the CX 430, CX 500 and CX 600 which while sound good, are not nearly in the same class of reliability as the CX-M designated new psus.
An rx460 system needs a 400w psu. With that 8350 you'll have to decide, OC or not. If you don't OC, the 430 will be fine. If you plan on OC, you'd be better off with a 500, if the 600 is a free upgrade, that's fine. Since I have no idea who actually OEM the Cyberpower brand psus (they are subject to change at any given time due to pricing and/or size) I'd probably be more inclined to trust the Corsair CX, but I'd take a 550w CX-M over a 600w CX any day.
