Mine is an EVGA Supernova 650 GS, 80+ Gold, fully modular, £95 at the time but after a bad experience with an XFX PSU i thought i should spend a bit more and go for higher quality, no regrets on that, it had a 6 year warranty, which is about to expire.
Its essentially a SeaSonic unit, like you i was carefully reading reviews and it did well in those, good tight voltage ripples and all that...
The PSU is a very important part of your system, it powers everything, if its good you will have a smooth, efficient, dependable system, which is exactly how everything i've had plugged in to it over the years has behaved.
EVGA are getting my money when it comes to replacing the PSU, if they expand in to a lower range of motherboards i might even get one of those when the time comes.
Edit: 5 year warranty not 6, so its now out of warranty.
