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.
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.
About a month later the power supply began acting oddly. I'd hit the power button and it wouldn't spin up. The PSU wouldn't turn on right away. When it did, it would power the machine for a second, then die. I broke down and bought a Coolmax LCD Power Supply Tester PS-228 (check it out on Amazon) for under $20, and found the power supply was providing less than 10% of the acceptable voltages on all of the primary rails and up to 15% less on the biggies.
The thing is, I don't mind a variance - power supplies are going to have a little variance here and there. If you have a power supply variance over or under of 1% or 2% on the PSU, it's not really going to affect your system. But this one tested out at 10% and 15% - which is not okay.
I'm sending it back right now and reordering a new 750W Corsair model - identical to this one except for the power wattage. Hopefully it's just a manufacturing glitch.
Other than that, I love these power supplies - this could be just an aberration in manufacturing. They do occur. But it's also an expensive pain in the assets to have to replace a PSU that's not functioning, and to boot your system to have to stab the power supply and reconfig cable each time - not happening. A powerup with an older PSU shows no issue with the system setup, so it's been narrowed to the PSU.
But again, other than that, the layout and the cords are fantastic and the casing is great. I love these things, I just wish my specific one didn't have such low variances.
Incidentally, if you're building a system, the Coolmax LCD Power Supply Tester PS-228 or a similar tool that will autocheck the PSU for you when you get it unboxed will save you a HUGE amount of time and energy troubleshooting for the PSU. It's $20. If you're building your own system, spend the dollars and get one. It's like a ThermalTake SATA drive dock - they pay for themselves really quickly.
