2 out of 5 eggsannoying whinning noise

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: So far a very good and stable power supply except for the constant whining noise.

Cons: After about two weeks of use the power supply is now whining constantly and gets louder under load, very annoying and not acceptable. I would not recommend this PSU. I'm returning this one and trying a 850W EVGA.

2 out of 5 eggsLike the Mod. Received broken

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I have never owned a modular power supply. I love it. Installing was easy and the box itself is not too bulky. The modular option made cable management pretty easy I am a beginner at that sort of thing and while it was not the cleanest management ever, it looked way better than what I had before.

Cons: I unfortunately received a dud power supply. after rigorous trouble shooting it was determined and confirmed by others that the power supply simply was inoperable.

Other Thoughts: Sad that this otherwise easy set-up and more powerful supply was broken. going to try and get a replacement or possibly a refund.

2 out of 5 eggsNoisey

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Capable, solid build

Cons: Fan runs intermittently, but when it's on it sounded like a creaky bicycle. Additionally it made my speakers buzz while on (bad shielding?) in a way that my old Zalman 1KW did not. RMA'd and back to the Zalman for now.

Other Thoughts: Most probably defective.. and I have to suspect the shipping as it arrived with uninflated plastic padding surrounding the box -- not popped, it seems newegg just never inflated them :-/

1 out of 5 eggsProbably an exception to the rule

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Beautiful load of wattage, semi-modular cable design.

Semi-mod design included a 24-pin ATX that was easily adjustable to 20. It also had two PCIE cables in the default set. Probably a bonus for most people, but was not for me as I am currently using a single video card.

Cons: Dead withing 15 min of installation. Machine was able to post, but when I had everything connected, suddenly no-dice. Had to return it.

Other Thoughts: Fortunately Newegg is generous about returns. Already RMA'd a Rosewill capstone 750 eariler this month (preivously worked for 4 months) and now this. Next I'm going to try the Seasonic X650 Gold. My system only pulls about 350 W, so the smaller unit should still be all I need.

Unfortunately, the name of the PSU game is "statistics". Even the very best are still around 10% RMA.

3 out of 5 eggsWhinning/chirping noise

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Appears to be a good power supply, fan only comes on when under load.

Cons: There is a whinning/chirping noise for about a minute when the fan comes on. Then the noise stops, not sure if it's worth returning for this problem. A power supply that costs this much should be totally silent. I gave it only 3 eggs because I hate noise in psu's.

1 out of 5 eggsDied after 4 month

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Clean simple install, Cable management.

Cons: Worked great for 4 months unsure if the failure damaged other components in my rig but I do know the power supply is toast.

Checked the smart ups logs and power was normal and did not receive an out side power surge. The failure appeared to come from the power supply itself.

5 out of 5 eggsClean, bundled packaging, runs like a dream

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: - Cables are bundled neatly and efficiently, with extra zip ties for tidy storage.

- Very easy installation. A couple of screws, a couple of plugs, and you're done!

- Plenty of adapters and easy labeling on the power supply give you some flexibility. Also, you can add/remove extra cables depending on your needs. If you're not hooking up that many devices, you can get away with just a couple of power cables, and leave the rest in the bag for the future.

- Smells like a new car. I'm not joking. This is the nicest packaging I've ever seen for a power supply.

Cons: - A little bulky - mid-size ATX towers might have some space issues, but you'll squeeze it in.

4 out of 5 eggsGreat PSU so far, sketchy rebate policy

This review is from: CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Good output for the money, it runs cool/quite and it's partially modular which keeps the case from looking a mess.

Cons: If the mail-in rebate is a clincher for you, know this; I ordered my PSU on the last day the rebate was offered at the time, I sent in all my documentation per the instructions and Corsair confirmed receipt and said it would be a few weeks. I check my tracking number only to find that the status is "Invalid" because it was postmarked outside the eligible program dates. Don't bank on getting that rebate because I'm not the first and likely not the last to get the short end on that one.
