5 out of 5 eggsAwesome Power

Pros: Easy to install, lots of cords, lots of connectors, cords have good length, wrapped cords make cord management easier, runs quiet, dependable. Bought to for my new photo/video editing build and ran it for 8 months in my old system while I gathered components for my new build. Runs just as great in my new tower as my old one.

Cons: The wrapped cords and excess length can be a real issue for those with tight cases. I just upgraded from a regular (an old C*oler Master Centurion) to a mid-tower case (AnT*ch Three Hundred Two) and boy it was nice having the extra space for these cables in the new tower. It was quite a tight fit in my old tower.

Other Thoughts: You may need to get some adapters for legacy hardware components if you are like me and hang on to old things that still work and keep transferring them to new builds.

5 out of 5 eggsCorsair

Pros: PSU has a solid feel to it. Cables are all wrapped. Providing good power to my system and I have been gaming for 4 days straight after installing it to make sure it can hold up.

Cons: None at the moment. Though if anything happens, I will come back and modify my review.

Other Thoughts: I got the 850W version.
It's powering an i7 920 OC'd to 3.8 with HT off, ASUS, X58 mobo, 8GB RAM, 1.5TB drive, 2 SSD's, 9 fans, DVD drive, a 560Ti and a GTX 260 for PhysX. This thing hasn't let me down so far.

5 out of 5 eggsNo complaints

Pros: Owned this for more than a year after having another PSU burn my old computer. After extensively researching on HardOCP and other sites, I settled on this PSU. No regrets.
Lives up to it's claim on ErP-compliance and good energy efficiency.
Quiet, no noise at all in my case. Exhaust is cold. Cables more than long enough to route behind the motherboard.

Despite my efforts, I can't seem to get the voltage on any of the rails to deviate more than 1%. Very stable unlike my old PSU which would fluctuate damagingly under varying load.

Cons: Not Modular :(

Other Thoughts: Corsair Obsidian 550D Case with 4 high performance 14cm fans.
MSI GTX 570 Frozr 3 OC to 800Mhz core.
i5 3450 @ 4Ghz
Asus Z77 Sabertooth Motherboard.
2 HDDs and 1 SSD.

1 out of 5 eggsJunk

Pros: Powerful enough to run my system, Was packaged nicely.

Cons: Psu failed out after 3 weeks of use. Its Emitting a high pitched sqeal from its internals.

Other Thoughts: I bought this PSU because i was looking for something powerful but, a 1000 watt psu was a bit overkill. I WAS a corsair enthusiast, my rig being made up of mostly corsair products. I bought my first of these psu's and when I took it out of the box, there was a cable pulled right out of the back of the cpu. I took it back and got another. This one, after 3 weeks of ownership, started emitting a high pitched squeal that would drown out even my headphones. I contacted Corsair VIA the web and they sent me an RMA which is great EXCEPT I have to pay for the shipping to them on top of the fact that I will be without a CPU until they send one back to me? I have lost faith In this company. My Case came to me all bent and banged up, I have had a dead stick of ram right out of the box and now a junk PSU. Even at this price point, I could have bought a nicer PSU from another company but I was a loyal customer until this. They should either have a printable pre paid postage rma stamp or, send out a new PSU and have the customer send out the old broken one.

1 out of 5 eggsLasting Power Supply NOT

Pros: Nice black case, long cables, 5 year warranty, cute bag.

Cons: First one worked for about 1.5 years then died.
Second one worked for about 10 minutes then died.

Other Thoughts: I have a 700w PSU that runs hot, so I wanted one of the 80% PSU to cut down on the heat. I bought the first Corsair TX850 2 years ago from NewEgg and for about 1.5 years everything was fine. Then the PC on boot up started not displaying video but, with a few times of turning the PC off and then back on the video would start working again. This continued to get more frequent until one day the PC was on and a moment later it was turned off. With a power supply tester I found that the PSU had died. So no worry it's got a 5 year warranty so, I got an RMA and put my old 700w back into case (it still worked, nothing else was bad) and waited for the replacement PSU. When I got the replacement PSU from Corsair everything looked brand new, so I installed the PSU fired up the PC and 10 minutes later the PC just shut down. Again got out the power supply tester and found out the replacement power supply had died. So back to the old 700w again (it still works). If you want a PSU to last don't buy a Corsair TX850.

1 out of 5 eggsthe fan spin up

Pros: worked

Cons: gets relay hot with out fan spinning up
will never spin up system never gets that hot
poor design

Other Thoughts: will never buy a thermal trip fan PSU

Manufacturer Response:

Dear Corsair Customer,
It is normal for the fan to not spin unless it needs to and for most types of builds the fan will not spin very often. . Just to be sure your PSU is functioning normally I would recommend that you please contact our Tech Support team using the following link and they would be happy to help troubleshoot further or replace the unit for you through an RMA if need be.
They can also be reached by phone using the toll free number listed on our contact page:
Thank you,
Corsair Customer Support
