N/A 8/31/2010 12:37:03 PM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5Awesome Pros: By far the best PS Ive owned. Very professional packaging. all connector cables come in a separate pouch- no more storing extra connectors in the desk drawer. large fan= cool PS. Cons: none Did you find this review helpful?

Sir Beregond 8/28/2010 8:46:21 PM Tech Level: 4/5 Ownership: 3/5	Rating: 5/5Corsair is simply the best Pros: -This PSU is quiet. I don't hear any noise from it at all. -Modular design that is well done. They have made the cabled everyone would use (24 pin ATX, 8 pin EPS, and 1 6 pin PCI-E) fixed since they would be required. Everything else is attach as you need it! -Modular Cables themselves are flat, which does help a lot in terms of cable management. -80 PLUS Silver -Single 12 volt rail design. Cons: -I would really have liked the 8 pin EPS cable to have been longer. When you have a bottom mounting case, this cable is never long enough to keep it from going over the motherboard and ram. No biggy, but I'm a bit of a perfectionist about cable management. -The SATA and Molex modular cables seem a lot longer than they need to be. I have a Cooler Master CM 690, which is big, but still a mid tower case, and these particular cables neded to be folded up a bunch to get the slack out of the way. -Not 80 PLUS Gold? =D Other Thoughts: Can't go wrong with Corsair. Once you go Corsair you never go back. They simply cannot be beat in the market of PSU's. Corsair just delivers the highest quality, even in the packaging. Don't pass this up!

hoodlum 8/28/2010 10:22:24 AM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5Absolutely satisfied Pros: Really nice cooler. Comes with loads of extra cables, seems very well built. Don't think of going non modular, I am soooo glad I spent the extra bucks for modular design. You know you are getting a nice piece of kit, just the way it is presented in a nice little bag, like a fine piece of jewelry. Cons: none. Worth every penny. Other Thoughts: i7-930 mildly OC to 3.6ghz with HT, ASUS P6x58D premium, Thermaltake Frio, Sapphire 5870, intel x25m SSD 80gig, WD 2tb black, Corsair Dominator 1600-6gb, Cooler-Master HAF-X, Corsair PSU-850 HX Did you find this review helpful?

N/A 8/27/2010 5:03:04 PM Tech Level: 4/5 Ownership: 2/5 Verified Owner	Rating: 5/5A+ Pros: Very nice PSU! -Good looking. -850W -Sli/Crossfire Ready -Stable -Runs quiet -Black matte finish -Plenty of cable -80 PLUS SILVER Cons: We can still see the rainbow of colored wire at the end of the sleeving of the not modular cable. Other Thoughts: Corsair = Quality Did you find this review helpful? Thanks for the valuable feedback you provided!
Ricked 8/27/2010 1:50:49 PM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5850HX 850W Pros: Wow. Let's start with the felt carrying case enclosing the power supply itself. I could tell as soon as I opened the box I had a high quality power supply. It also came with a carrying case for the various power connectors for safe keeping. The separate connectors so you only have to use the cables you need for your hardware is unbelievably convenient and such a space saver for your case. Routing power has never been easier. Cons: LOL CONS?! Other Thoughts: I recently had been becoming increasingly disappointed with my computers performance and figured that the only real culprit was my video card. I went from a XFX GeForce 9800 GT to a Gigabyte GTX 460. What a huge difference. Changing cards meant I needed more power however. I am exceedingly happy with my decision to go with a new card and this new power supply. This power supply should tide me over for at least the next 3 years. Did you find this review helpful?

tritonice 8/24/2010 12:23:01 PM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5Attention to detail. Pros: Wonderful product. Using it to power i7-930, one 5870, 3 hard drives and various others. Plenty of power to expand later. Modular design makes for easy install and no extra wires. Can't recommend enough. Cons: None. Other Thoughts: Supply is wrapped in velvet bag like Crown Royal. Cool. Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 8/23/2010 7:25:39 PM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5Great Buy! Pros: After upgrading my video cards I was having power troubles. I slapped this bad boy in and now I'm trouble free. My old PSU was a 2 rail setup. with this single rail setup, it's an easy setup and clean power to every thing. Can't go wrong with this one! Cons: Minor one listed in "Other Thoughts" Other Thoughts: Great sets of cable supplied, but I wouldn't mind different lengths. For my DVD drives I have a lot of slack to hide.

mrcmtl 8/23/2010 12:20:53 PM Tech Level: 3/5 Ownership: 2/5 Verified Owner	Rating: 5/5Well done Corsair Pros: My first Corsair PSU, and I must say I'm impressed. I've had several OCZ, Antec and CoolerMaster PSUs, and this Corsair definitely is the best of all. It's dead silent. And the fact that it's modular gives less cables to manage. Cons: Each cable set has 4 connectors. I wished they would have put only 2 or 3 because now I still have 2x2 connectors dangling inside my case. Not 80PLUS gold :P. Other Thoughts: It's a bit long, so for those who have a small case, you better watch out. Did you find this review helpful? Thanks for the valuable feedback you provided!
Federal1 8/22/2010 7:28:22 AM Tech Level: 3/5 Ownership: 2/5 Verified Owner	Rating: 5/5Corsair 850hx Pros: Awesome deal, cheaper than the 850tx. I love the packaging very professional, fast shipping. Was ordered Monday received Tuesday. Cons: None, Corsair name speaks for itself. Other Thoughts: I have not setup the PSU yet. So cannot comment on the product itself. 0 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
Randar 8/18/2010 4:20:56 PM Tech Level: 3/5 Ownership: 1/5 Verified Owner	Rating: 5/5Quick and silent Pros: Quiet, not a BFG brick. Received the new PS in less than 24 hours.....quick! Cons: None as yet...but then again I'm not expecting any issues. Other Thoughts: My 800 watt BFG failed for the second time in 6 months so I called them up and to my surprise they told me my valid warranty wasn't worth diddley, because the company was being liquidated. My new Corsair 850 HX is way quieter than the BFG , I can barely hear it at all. So far so good. Don't buy anything made from BFG unless you don't care about warranty.
