from completed build Azalea: the Ultrawide-capable rig

A high quality power supply with enough to power an SLI rig. I really like the Corsair Link software this uses, too. It comes with a 10 year warranty, too, in case those specs like "Japanese capacitors" didn't mean much to you.

Good PSU. It's very efficient and delivers clean power. The Corsair Link is also nice to monitor it. Fan hasn't ever spun up for me, so it's silent too.

if you want to use included 24pin cable, first go to gym!... cables are not good but the power it self is solid so 5 star remains.

from completed build My first build

Just a power supply, was running pretty hot at first, but I changed it in Corsair link to turn on the fan at 40%

So far, much better than my old 950W bronze Antec. The modularity was great, and the noise (or lack there of) it creates is a blessing.

Awesome PSU. The fan hasn't come on even once, even while gaming (it does work, though, I tested that to be sure). Silent, modular, stable. Really really love this!

from completed build Nzxt S340 Elite AIO Cooling build

Solid PSU - that is over-specced for the system so that it will be able to run without needing to invoke its fan unless I really decide to push the overclocking on the system.

Gran fuente, potencia de sobra, totalmente modular, da gusto usarla.
