from completed build Tiny Tina 2.5

Well, it hasn't broke yet. Has cheap chinese capacitors according to some review, but it won't blow up either. Yaaaaaaaaaaaaayyyyyyyyy

from completed build The Final Wave

Modular, Powerful, and small. Perfect for a Gaming Build. The only concern is the Temperature-based automated Fannless mode, I have never seen the fan work on this Power supply even at 50*C.

from completed build Minimum

If you have the spare, just go for full modular power. this will save you tons of trouble for cable management.

from completed build "White Wolf"

I love Cosair PSU's so I can't complain much about have a faulty one...It happens and their custom service helped me with no questions.

from completed build i7s-gtx980-modest

Pros: Excellent, efficient, modular PSU. Cons: The only complaint (and I'm nit-picking, really) is that I felt like the connectors on the PSU itself didn't feel like they "clicked" enough on insert to my satisfaction. Anything power-related feels better when it has a nice big "ker-chunk" (or size-related equivalent) when it's locked in. Will these pop out? Certainly not, but I like the tactile guarantee.

Again, just picking nits. Still rate 5/5.

from completed build White Widow

This is a great power supply. 80-plus gold certified. This thing is pretty quiet, even under load. No complaints, good price, good quality. Solid buying decision.
