Ah, the annual fully modular PSU post. 
I have an i7 with GTS 450 and 2 HDD. My UPS says full load <= 300W (idle is 170W). Probably not going to upgrade for a long time (at most, add 2 more HDD down the road).
Would I be OK with 560W Seasonic, or should I go for 750W Seasonic? I've heard these PSU run best at 50% load anyway.
I'll take any other recommendations if there's something better I've missed.
