Tier 2 PSU, reliable and efficient. Not enough connectors for multi-GPU setups though...

from completed build The Screamer Mk-1

I was suckered into getting a cheap Rosewill 600W supply, and quickly learned online that it really wasn’t the most ideal power supply to have running long term in a powerful rig like this. So, I got smart and swapped it out with a SeaSonic G-Series 650W power supply. It’s from a very reputable company, very efficient, and works wonders and the fan is very quiet, even at heavy loads.

from completed build BFB (Black Friday Box)

This was my first build so maybe my expectations are off, but the power cable to the CPU headers seemed very short, I could barely route it through the back of my (admittedly large) case. Cables were stiff and hard to manage. I would only recommend this for mid-tower ATX or smaller cases.

On the plus side, it has good reviews for being high quality, and it DOES have enough PCI-E connectors to support two graphics cards if the cards use less than 225 W each (such as the GTX 970).

from completed build Zerk2012

Seasonic Gold Quality!!!!! Took one star off for the cables they really need to rethink that. It was a tough stretch to get all my drives plugged in and the modular cables are flat, the others are just the regular sleeved round cables.

I will not even try to pretend to be able to test a power supply so lets read what OklahomaWolf said about the SeaSonic SSR-650RM: http://www.jonnyguru.com/modules.php?name=NDReviews&file=print&reid=348
