While it's definitely more than you really need, it's better to have some head room.
Anyway, let's hear what OP has to say.
HD 7790: 100W (http://www.techpowerup.com/reviews/Sapphire/HD_7790_Dual-X/24.html)
i5-4670K: 84W (I may overclock, but I will definitely be undervolting, and power consumption is proportional to the square of the voltage, so this number is likely to be lower than 84)
motherboard/ram: ~60W
SSD/fans/etc: ~10W, if that
USB devices: negligible, so I'll say 6W to give this a nice round number
Total: 260W
Even if you factor in capacitor aging with the PSU, which is a little over a year old right now, it should be able to handle this load until the age of 4 (400Wx0.9^4=262.44W). And that's assuming maximum power consumption of 260W, which this system will likely never pull. I'll need a new PSU in 2.5-3 years, but that's not unexpected. Incidentally, a 7870 draws 144W max, so if I were to go with that card, I'd probably need to replace the PSU in about 1.5 years. I understand the instinct to buy a larger power supply. It's easier to buy more than you need than it is to calculate what you actually need.
That said, I didn't start this thread to talk about the PSU choices. Where I'm lacking knowledge is with Dolphin and GPU performance.

admin89: I didn't know that 4xIR and 2xIR+4xSSAA were the same thing. Is the processing actually identical? Will those processes produce identical images?
NaturalViolence: What is the AMD overscanning issue you're referring to? I haven't owned an Nvidia card in almost 10 years, so I don't have any personal experience to compare the two brands.
Garteal: So 7790s are inferior to 6850s? In GPU hierarchy lists I've seen, the 7790 is listed as a superior GPU. Here's one example: (http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html). I'm far from an expert on this subject, so if the links I've seen are wrong that's fine. But I would like to hear your reasoning or see some evidence.
