Ease of Use

I measured the wattage consumed by the Corsair PS and by another, much less expensive PS on a different and less powerful motherboard/CPU combination. I save about 50 Watts using the Corsair PS. That is about 1200 Watt-hours per day, or about 36 KWH per month. At 10 cents per KWH, that is at least a savings of $3.60 per month, assumming the computer is always on. In other words, aside from the Corsair PS's other features, the payoff period in terms of energy savings is between 23 and 24 months. This is a very conservative estimate; your milage could differ. quote

This is a great power supply, plugged right in and worked flawlessly. It is also much more quiet than my previous Antec EW PSU.

I bought this for $100, looks like there is a mail in rebate now, but I still think it was a great value. I've used it for only a few days, but this bad boy is awesome. Very quiet, performs great. Very high amp ratings, enough to power quad core and 8800GT and multiple hard drives. There are plenty of power cords, can't take them out, but I am able to tuck them away in my good sized CoolerMaster 690. Very easy to install. I'd give this a 10!

Amazing Price, Good Amps, Very Quiet, Low Heat, Ne

on 6/10/2008

A fantastic price for an amazing PSU from a very reputable company. [[PROS]] >The 12V amperage (very important for high-end video cards) far surpasses the required 24A for my nVidia geForce 9800GTX. Most PSUs don't meet this requirement. >Dedicated PCI-E connectors for high-end video cards that need two PCI-E power connectors. >Very quiet operation >Almost no heat generated or emitted from back of computer. >All wires are fully sleeved in attractive/air-flow conducive black mesh sleeving. [[CONS]] >Could use modular wiring (wires that you can attach/detach). >Extremely heavy. Probably the heaviest component in my system. [[MY SETUP (works great)]] >MSI motherboard >Core 2 Duo E8400 >Nvidia geForce 9800GTX >2 HDDs, 1 DVD-RW, 1 floppy
