excellent quality,
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.

|Superb – in every way,
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). These come in a nice cloth (velvet-like) bag for storage of the extras. Why so many cables? Power and data for multiple GPUs, 12 SATA cables for extra storage, etc. Also, the manual was well written in plain English with logical instructions and detail.
I did a ton of research on PSUs and talked to Corsair pre-sales tech support before buying this – they were great (although I had to leave a message to have someone return my call). The tech was super knowledgable and very helpful. Not the cheapest around, but after 4 months of daily use, I’m convinced of its value.
Bottom Line:
I am simply thrilled with my purchase, would recommend it to my best friend and WILL buy Corsair again.

|AWESOME PSU,
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. But the 850 also has more connectors and cables, and I’ll probably use them by the time I finish with my build.
5) This unit is extremely well packaged by Corsair – important for shipment. Comes with a nice case with velco closure for housing the cables, and an extra black velour draw-string bag for cables if you want. Not important to me, but others seem to like it.
6) Installation was a snap in my HAF X case as was cable management. AND I did NOT need the extra 24PIN NZXT Mobo extention power cable I though I would need because of the size of this case. The length that came preconnected to the PSU was plenty long to fit out the bottom case slot, route up the back of my case, and back in thru the case holes, then and connect to the Mobo 24 pin connector. The HAF X is a Monster case and my Mobo (Asus P8Z68-VPRO/Gen3) sits high in the case, so this cable length was good planning on the part of Corsair. The ONLY reason I’d use this NZXT extension cable is that it is ALL BLACK, including the short 1/2″ of wires coming out of the cable by the connector. That short stretch of wires on the Corsair 24Pin power cable are colored. Merely cosmestic. The 8PIN power cable at the top L of the Mobo, however, was another story. The Corsair cable 8Pin Power cable for the Mobo is too short, but the HAF X case comes with the extension cable that was needed. If you’re case doesn’t and it’s big — buy one. NZXT has nice ones here on Amazon.
7) Power switch (on/off) is on back of unit.
8) You should note in the User manual that the use of “other vendor” power cables with the Corsair PSU VOIDS the warranty on the PSU. Your choice. But the length of warranty is great.
9) Single Volt Rail — don’t have to worry about spreading power across separate rails.
What could be better?
1) The User Manual – but only if you’re unfamiliar with power connectors as I was at first. On the flip side, there are many excellent web sites anxious to teach you about power connectors. I used them thoroughly before setting up so I was sure to understand how the different power cables work, why, and what not to do – the No Nos. Also helpful to learn the best way to add devices to power lines.
2) I’m not crazy about the SATA power cables with 4 per cable, but they were NOT upside down as some have suggested, and they do make for good cable management. Still, I set up my multiple hard drives on as many different cables as I could with some on one cable line based on what I read about voltage drops across power lines. Would be helpful if Corsair put more basic info in their manual.
2) Corsair website. Didn’t seem to operate 24/7 to get a user name and password. Their website works great for product info, comparisons, and power usage calculator needs though. Haven’t needed it yet for much else. Also have a 16GB kit of Corsair Vengenance RAM which works absolutely great in my system.
Yes – I’d buy this unit again.
