It's hard to find lower wattage PSUs with the connectivity needs you're after at competitive pricing.
Alternatives that would actually offer some improved efficiency on the low end would be XFX XTR Series P1-550B-BEFX 550W, which might offer about 2% better efficiency than the HX650 at low loads.
Or.. The Rosewill Fortress 450W and 550W, which would offer about 4% better efficiency than the HX650 at low loads. This would require the use of Molex to SATA power adapters.
If maximizing efficiency *for the sake of it* is a goal these similarly priced alternatives may offer a way to do it. As pointed out, even the little 450W fortress would technically be large enough to power regular 80W haswell, GTX780, 6HDs and all system fans/bridges/controllers etc.
And i'm an Intel guy myself. Ever since I made the switch from AMD to Intel about 4 years ago I've just loved Intel. Superb performance and great power efficiency. And with this being a media server, power efficiency was a main concern for me hence the WD green drives and 90 Plus Gold psu. I know I could save money by going to AMD, but I just prefer Intel. And this was never a really tight budget build to begin with so I don't really mind spending the extra $$ for the Intel board and cpu.
9/10 builds are better off with Intel. I'm *usually* in a position of trying to make that
point here on OCN. Your server system is one of the unusual cases where an AMD build has validity
due to the feature rich high value nature of their inexpensive motherboards. Given the lax budget I can appreciate sticking to Intel if that's what you like
... If you don't mind me asking, I didn't see which CPU specifically you had in mind (sorry if I missed it). I'm mostly curious. Thinking a T or S model CORE or E3-12X5V3 series might be fun.
But yea, the server will be pretty simple. Its going to run Ubuntu, and I'm going to run Plex on it for all my Movies, TV and Music. That's about all It's going to do. I did want it to be capable of streaming 2-3 HD movies at once since I had roommates who will also be using it, but that should be no problem with this setup IMO. And who knows, I may even install steam and a few linux games on there just for kicks since this will be hooked up to my big screen. That's partially why I wanted an overkill PSU, future expansion. I could add a $250 gpu into this thing no problem.
Sounds like fun. You can even install the windows version of Steam with a few minor tweaks to wine settings. Quite a few windows games work on Linux with Wine.
Best of luck with the build and thank you for the consideration.
