4.0 out of 5 stars Bit the bullet - but the system survived
Reviewed in the United States 🇺🇸 on July 23, 2019
I guess I got unlucky.

When I was installing my original PSU, I noticed through the fan grate there was some grey material inside the unit. I guessed it was some sort of thermal paste or something, maybe even protective gel to prevent electrical arcing. The unit was completely factory sealed, never opened - and yet it had this grey, seemingly solidified goop in the bottom. It was a little weird, but I didn't think much of it at the time.

I'll get back to this goop later on in my story.

Corsair's PSUs are rather reputable, and this one features a 10 year warranty. Unfortunately for me, my own power supply died about 2 weeks after installing it in my system. I heard a loud electric crack from my computer, and the entire system immediately shut off. Hitting the power button didn't do anything.

"Oh [censored]" is what exited my mouth, having a PSU die on you is VERY bad. Either only the PSU bit the bullet, or the PSU killed not only itself, but everything that was attached to it. Everything in your computer is connected to the power supply one way or another. Hundreds or thousands of dollars of damage could be on the line.

Fortunately, only my PSU bit the bullet - it didn't kill my entire system. After detaching it from my computer and plugging it into a wall, I hooked it up to my old PC and hit power. The PSU temporarily gave it enough power, but then made a clicking sound - I'm guessing some safety breaker in it was triggered, and the thing shut off.

RMAing the PSU was reasonably easy, however from my experience the only way I could get Corsair to advance my RMA process was by calling their support center. I had to contact them twice on the phone before my RMA request was approved and I was able to ship the PSU to them - on my own dime, mind you. They don't cover the cost of shipping back to them.

I'm aware these large companies have lots of calls and tickets to deal with, but given that my RMA was only pushed along after phoning them twice, and taking nearly an hour in hold time/call time is unacceptable. Perhaps I had my problem during a bad week for Corsair, but the experience was still quite frustrating, especially when a brand new product goes bad.

Fortunately, they shipped a new one to me the day they received my dead PSU - with 1 day expedited shipping! My new PSU was at my door the very next day after the broken one had arrived. So... I guess that makes up for the $17 I spent to ship the dead one back to them.

Upon receiving my new PSU, I again inspected the interior of the unit. To my surprise - no grey goop. I couldn't spot a drop with my eyes and a flashlight. In my previous unit, the one that died, grey goop was painfully obvious, and immediately spotted through the grate. This unit? Not a drop.

5.0 out of 5 stars Elegant, white PSU
Reviewed in the United States 🇺🇸 on August 9, 2022
Used this in a recent build powering a i5-12400f and an RTX 3090. Handles both overclocking and undervolting remarkably well. Build quality is superb. PSU cables and clips are solid if a little stiff. Eco mode is terrific for when you're not straining your system and want a quiet experience. Perhaps best of all, this is known to be one of the best power supplies as ranked by independent power supply testers as a premium A-tier product. (Google: PSU Tier List)

3.0 out of 5 stars Cables
Reviewed in the United States 🇺🇸 on October 31, 2022
The Nylon jacket and rigid tape on the cables is totally unnecessary for this type of scenario ‘ Computer Build‘ It only makes the cables stiff and hard to maneuver and a undesirable appeal . It does not give the wires or insulation any type of protection inside a computer. I did stripe mine. If so make sure not to damage the insulation or you can buy their “Custom Package” Same cables but without the nylon jacket and type
