Great psu with platinum efficiency. I've had no problems so far.

Utter and absolute overkill, but soo quiet

Solid PSU with stable voltage readings.

Got this when it was on sale. Really dont need all the fancy stuff that this supposedly comes with but i wanted to get a power supply that i really liked and that came from a respected manufacturer.

Great modular PSU with 80+ Platinum efficiency. The modular cables are plentiful, generous in length, and have several connections available. Runs cool and quiet. Will even turn of its fan if it doesn't need it.

Excellent, very reliable power supply so far! It comes with a mini USB cable for the digital data acquisition software of Corsair. Reaches peak efficiency of <93% at 350-400W load.

It does the job, while being certified as Platinum.

I have had this unit running my main PC for 4 years (it has lived through three iterations), and I still have 6 years left on the warranty. Insane.

(UPGRADED) My old 400W platinum fan-less just wasn't keeping up with this system when loaded. I decided to upgrade for limited future-proofing. I carefully chose this based on several factors: Corsair's great reviews, including reviews for this model, platinum rating, fully modular, minimum 650W, fluid dynamic bearing fans, fans only run as needed, and PSU to system communication (Corsair Link). The price is pretty good for these features. If it fits your need, I highly recommend it.

Brilliant PSU. Fan doesn't spin until the unit detects enough heat to warrant turning it on. I haven't seen it spin yet (despite smashing the pc with a 2.5 hour AE render job).
