Price History (Excluding Tax & Combo Deals) History:


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

The Power Supply is good and gets the job done. but unless you want a hot running system then this is useless. The fan has never run even when maxing out the wattage and temperature ratings for the power supply itself. There is no way to force the fan to spin all because of Corsair's Zero RPM Fanless Mode.

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.

from completed build First time gaming build

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

Works, powers everything up :)
