Seasonic SS-660XP2 ATX 12V / EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I burned this psu in on a old P4 system by running it nonstop for a week to stress it.
Rails are dead on, no high pitched noises or voltage hum.
It's the V2 version.
Ability to allow the fan to run slowly for more airflow even though it's not really needed until after 50% draw.
The Sanyo fan will easily outlast the PSU even running 24/7.

Cons: None, I even received my MIR for 20 bucks, it's always a bonus when those show up.
A PSU of this power and quality for $90 is a steal!!

Overall Review: As other people have mentioned this psu is designed to be mounted on bottom cases due to the orientation of the sata plugs. They run bottom to top, not top to bottom.
You can mount it on top but the lines would go towards to bottom of the case, bend and go back up to be correct.
A tall tower case the line most likely won't make it length wise.

Pros: Very nice packaging.
Hybrid mode: Fan stays off until heavy power draw

Cons: Does not boot the system with a GTX780 video card!
Boots perfectly fine with an old 9600GT.

I'm a professional engineer and have built over 70 systems so I am sure I have everything connected properly and that the video card works perfectly in this system with other power supplies.

Overall Review: None
