The Thermaltake PSU calculator has a pulldown for capacitor ageing (bottom right corner) which I set to 25% to get my 410W recommendation. I also included a DVD burner, 4 sticks DDR3, 1hdd, 1SSD, 3- 120mm fans in that figure. The OPs i5-3470 (non-K) can't overclock (much
), so the only real overclocking that's going to happen on that system is a GPU overclock. The Thermaltake PSU calculator doesn't have the ability to consider that (does for CPU though) so I'd be cautious with GPU overclocking on the CX430 to be safe. Also, the max efficiency for PSUs is generally in the 50% load range, which is why many PSU calculator recommendations provide a ~2x peak wattage excess.
This is one of the most detailed PSU calculators I've seen/used and being from a PSU manufacurer, I tend to trust their recommendations based on it. Of course, if you're buying new, there's nothing saying that you can't exceed their recommendation. In fact many people buy overpowered PSUs simply because they have no clue what their system power draw actually is.
...And disregard the "recommended PSU wattage" that comes with GPUs. They obviously don't take the rest of the system specs into consideration, so they have to make a worst-case-scenario blanket assumption.
