    Impressive So Far!, November 20, 2010
    By 

    I have now been using this for about a week and am very impressed. I upgraded from an Enermax Revolution 85+ 1050 Watt Power Supply which was a critically acclaimed unit itself. I love the fact that this power supply is FULLY modular. Whenever you have to replace it you can just undo all the cables from the PSU and leave the cables intact in your case. You then can remove the power supply easily and install the replacement (which of course would be a Corsair too)! Remember, the hardest part about installing or replacing a power supply is organizing the cables in your case. This is very time consuming.

    The power supply runs very cool, but I am only using about 25% of its power capacity right now. Unlike other reviewers who base their reviews on performance subjectively, I did test the power supply before I installed using a Coolmax power supply tester. Everything was tight!

    While there are other power supplies out there that compete with this (like the newly released Antec HCP 1200 Unit, I chose the Corsair because they have always been about Quality and Performance for the enthusiast from their memory only days. This unit also comes with a 7 year warranty versus 5 for the Antec and other competeing units.

    You can also get hold of Corsair by phone if you need to! They do not hide their phone number like other vendors all over the web.

    While this power supply is probably overkill for most, if you are a Computer Enthusiast, Overclocker, and/or Multi-GPU Gamer, this is YOUR POWER SUPPLY. Well done Corsair! Superb………..

    This review is from: Corsair Professional Series Gold 850-Watt 80 Plus Gold Certified High-Performance Power Supply – CMPSU-850AX (Personal Computers)

    This is probably one of the best psu’s on the market. The efficiency sets new standards, it’s extremely quiet (silent most of the time) and is good value for money.

    Highly recommended for those who need the wattage, or anyone who wants a highly efficient clean power source at any wattage. The fan doesn’t even move when using normal email, desktop or web browsing apps. When it does slowly kick in during gaming you won’t even notice the sound as the other fans (GPU, CPU etc.) produce more sound.

    The modular cabling makes for easy installation. It’s size is well within ATX standards so it should fit in most desktop cases.

    This is the power supply to get for two video cards, September 27, 2010

    Wow, this power supply is great. It has all modular cables, no guess work on where to plug them in since it is all on one rail, is totally silent, and looks good in a typical black mid-tower case. I haven’t heard a peep and I have been able to overclock my Intel i7 processor about 550 mhz and both of my GTX480 video cards with no noticeable noise and no, zero, nada freezes or reboots. So therefore I recommend this as a worry free power supply to buy.
