This PSU replaced an OCZ stealthXstream psu and by every regard it's of much, much higher quality. The PSU is very large so if you're not bottom mounting it be absolutely sure your case can tolerate a 10 pound brick at the top. The 24-pin connector cord is extremely long, giving people like me the ability to run it behind the motherboard (cord management) without the need of buying a 24-pin extension. It's modular so you only need to plug in the cords you need. And best of all, it's ultra quiet. I have six 120mm intake fans (3 intake, 1 cpu, 1 gpu, 1 exhaust) and one 200mm exhaust. My computer sounds like a floor vent when the AC is blowing; just a quiet hum of air moving. No whisp, no whine. Right away it was noticeably quieter than the OCZ psu this replaced.

The modular cables are stored in a velcro bag (two standard molex power cables, two sata power cables, and four 4-pin PCI-E adapters!!), the PSU comes wrapped in a velvet satchel, the packaging is over sized, and it's all heavily padded. In the end, Corsair did not cut any corners whatsoever in making this PSU. What you pay a little extra for in price is obvious when looking at and using this item. I highly, highly recommend it.

This is one of the best peripherals/upgrades I have ever purchased. I pulled out a perfectly fine Dell OEM Power Supply Unit (except for the fact that it was loud and couldn't handle "Step Approximated Sine Wave" battery power coming from any number of Uninteruptable Power Supplies) and installed this in its place...

Some products claim to be professional grade and usually disappoint - this one certainly is pro-grade - just look at the ambient temperature test specs. They are tested at full load at 50C/122F ambient! The unit comes with a 7 year warranty and is spec'd at 100,000 hours Mean Time Between Failure. I love its modular cable design (only uses what you need), its efficiency and performance. This PSU solved the problem with common UPS's not working with my Dell XPS Studio 435T/9000 and I was amazed to see that steady state power consumption went down some 35% compared to the old PSU - due, no doubt, to its nearly 90% efficiency. It's dead quiet because the fan only comes on when it needs to (I'm running at about 40% of total load, so it only seems to come on about 5% of the time, if that). This is a super nice feature when you're in a quiet office environment. I think my monitor makes more noise than this thing! :-) Bottom line - these new power supplies only consume what they need to, so don't worry about an energy pig just because it's rated at 850W. Only advice I'd give there is these operate at maximum efficiency when they are running at about a 50% load, according to Corsair's efficiency curves.

Packaging (product and shipping) was perfect. The modular cable system means that you'll be getting a total of 34 cable/connector assemblies (SATA, IDE, PCI-e, ATX/Motherboard data and power, and floppy/Molex).

I purchased this PSU for my new system build, and I'm so happy I did. First-time build.

This is a modular unit (cables are separate from PSU) except the 24Pin Mobo Power Connector and the 8Pin Power connector are permanently attached. Modular is the ONLY way to go. You use ONLY what you actually need. No unnecessary cables cluttering up space and reducing airflow. Cable management was a snap in my HAF X case.

1) These cables and PSU are a class act, for sure. All modular, heavy duty, well designed and made, solid latched connectors to the PSU, color coding for the PCIe cables (**Important) plus the all black cabeling looks great inside my black interior case with a window side panel. Incidential on color -- but a nice plus.

2) I won't review all the cables included. You can read that on the Corsair website, but there are more than anyone should need for this unit, even including old style floppy drive connectors.

3) The modular PCIe 6+2 pin peripheral cables accommodate both 6PIN and 8PIN graphics card connections. Just pull the 2 pin off the 6+2 pin and tie back the short 2 pin on the 6+2 if you have 6 pin cards and do not use the 2 pin for anything else. Do NOT confuse these "modular" 6+2 pin PCIe cables with the single "non-modular" 8PIN mobo power connector. Just a caution if your new to this. No Frying of Mobos allowed. Corsair color coded the PCIe connectors on the PSU end BLUE and also coded the PCIe slots on the PSU BLUE -- so avoiding this potential mistake if your new should be easy. Just an FYI from a newbie to any other newbie.

4) When comparing this Corsair 850W to the 750W: I purchased the 850W instead of the 750W. Was on the cusp of either.

The HX850 is an outstanding product, works perfect with 0 issues. More than ample power for complete quad-SLI/XFire. The cable management is fantastic, and the packaging of the product from Corsair was outstanding. I gave this item 5 stars for the product, but not for the shipping..

Be aware of Amazon's shipping for this item, I received this product in a box 3x the size of the package, with nothing stopping the package from moving N/S/E/W, the only thing in the box was loose(yes loose) air bagging on top of it. 1 Star for Amazon's shipping.

I pay for Amazon Prime and I have never seen such poor shipping, of all the times though, it is on one of the most expensive items I have purchased here, very unsatisfied.

The ONLY reason the product was not damaged was because of Corsair's fantastic packing job. The PSU is inside a plastic bag, followed by a cloth tie up bag, in cased in 2 very sturdy sheets of foam. The other end of the box is stuffed(nothing moves in this package) with a re-usable and very handy bag for your cables. All in all Corsair did a magnificent job on the product, and the packaging of it. Amazon, however, failed to ship this properly, but thankfully Corsair did their part to secure it.
