Okay, it's a power supply. Not much excitement there unless it starts smoking, right? But if you can't work up excitement, how about some respect? Like the 41 Ampere +12V rail (and there's just the one +12V rail, so you don't have to balance your power needs by hand.). How about the ability to auto-sense your input voltage from 90Vac to 264Vac, 50/60Hz? No more damaging your supply because the voltage selector was in the wrong setting.

Run cooler, too, because it can be up to 85% efficient, meaning less waste heat from the supply. Compatible with both ATX 2.0 and ATX 2.2 systems, it includes long cables for even full-sized tower installations. Nvidia SLI support It includes power connections for six SATA drives. A 120mm variable speed fan with double bearings gives good airflow with minimal noise. Active power factor correction helps deal with inductive loads (drive and fan motors, mostly).

A modern power supply for modern computers, just for you.

10 years and still going strong!

Pros: Still working without issue after 10 years!
Has all the necessary cables/connectors even for a modern build - upgraded from a 10 year old AMD dual core to a Intel i7 3770 with GTX 1060 without having to buy any additional connectors!

Cons: Wish it was modular. (Not really a con because I knew that it wasn't modular at the time that I bought it.)

Other Thoughts: Can't believe that this power supply still works without issues after 10 years - survived at least 3 moves. Was able to upgrade from a 10 year old setup to a modern CPU and GPU without an issue. Amazing!

Lasted nearly 10 years!

Pros: Bought this thing with a DDR2 build I did for my wife 10 years ago, just had to retire it last night because it seemed to be getting FLAKY, hadn't even actually died completely yet. That's a good run I'd say.

Cons: Only had a 5 year warranty so they won't replace it I imagine.

Other Thoughts: If they still make them like this one, get it.

Excellent

Pros: Everything. I've had this power supply for almost 6 years now and haven't had a single problem with it. It has been through multiple builds without issue. Thank you (JonnyGURU) for recommending it.

Cons: Nothing to see here.

Other Thoughts: Maybe people are just getting dumber, but when you look at the reviews for Corsair's older stuff and compare it to the new, it worries me.

It finally died. RIP

Pros: It worked solidly for 6 years through two PC builds. Never made strange noises and always had enough juice for my 560Ti and other components.

Glad I got it and am going Corsair again because of this.

Cons: It couldn't last forever.

Other Thoughts: Thank you Corsair for a solid PSU. One year longer than warranty.

Stong, reliable PSU. Good buy.

Pros: Performs its job well.

Hasn't died since purchase date over 4 years ago.

Cons: Lots of cables that are quite stiff, which isn't a good thing if you don't have a cable management system in your computer.

Other Thoughts: Need a 500W PSU, that's not modular? Buy this.
