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

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

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.

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.

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.

More than enough power for my system, they were sold out of the 750W
