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.

Pros: Powered my computer with ease.

Cons: Crapped out after 3 years.

Other Thoughts: While I can not complain that it made it 3 years (I have others that are much much older and are still working perfectly) for the amount paid I would have expected more.

4 out of 5 eggsCorsair HX850

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: Excellent clean power with 80 PLUS Gold rating that runs my 8350, SLI GTX770's, SSD, two HDD's, 6 LED fans, and dvd drive just fine. Plenty of cables and modularity for a million devices. Nearly silent even when the fan is running.

Not much more to say about this product.

Cons: And with my last statement with the silent feature, I have run into a problem. I have owned this power supply for almost six months now and it started making these electrical sounding clicks. They came and went and I experience them about once a week in groups until this last week. The sound is like popcorn, like when you connect wires together, and make current jump, which worries me. I keep my pc very clean so I don't think my fan has been ruined (I have my PSU bottom mounted on the case and is filtered), but it could just be that the fan has been upside down it's entire life. Docking two eggs because it happens for a solid 10-20 minutes EVERY day now and is very very annoying/agravating.

Other Thoughts: I love Newegg's service, and the quality of this Corsair power supply, but the sounds it makes are distracting in gaming and doing everyday activites on my PC. When it didn't make this sound I would have praised this product and given it a straight 5/5, but I'm docking two eggs due to the unknown popping noise which concerns me deeply that it may be a sign of failure and damage my other components.

1 out of 5 eggsRebate scam

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: It is a power supply as many in the market

Cons: Customer be aware. Corsair was advertising a $20 dollars rebate on this product when I bought it. In a market with so many other different choices of power supply, cost was a very important factor on choosing this product. After submitting all documentation required: invoice of original purchase, rebates forms, upc bar code and filling online application, today they updated the status to invalid.
This company is enticing potential buyers with rebates they do not fulfill. Please google corsair & rebates and you will know from other customers what they do. PLEASE CHOOSE OTHER BRAND.
