Off the top of my head some good brands to look out for are; Antec, Coolermaster, Thermaltake, Corsair, and EVGA.
Depending on what hardware you have now will dictate what PSU you need. Also note that future proofing with a PSU isn't gonna happen. Over time they wear out and should be replaced. I've read many threads on other forums where a person used their old PSU for a new build only to find out the MOBO wasn't working right and they thought it might have been RAM or the MOBO. Even going so far as to return the MOBO or RAM thinking it was bad, but it was actually the old PSU.
So don't look for a PSU to be future proof. Look mostly at the CPU and video card for future proofing. Probably the CPU above all else since if they release a video card that has like over 3,000 cuda cores and is 5,000 MHz or some damn thing, adding that to a computer with a less than stellar CPU and you have yourself a nice bottleneck.
It's probably safe to say that one should just upgrade the whole computer once every 4 years or so. Maybe 5 or 6 depending on what you use it for. In the computer world, technology evolves so fast. I remember when Skylake just came out which seems like yesterday and now there's Kaby Lake already. Probably not much different in CPU power though. Especailly if you over clock. But I haven't compared the two.
