If you're looking for a power supply to feed your hungry system, look no further. The new TX850W PSU from Corsair puts out an impressive 850 watts of power and supports the latest ATX12V v2.2 standards as well as EPS12V 2.91 standards. The unit is 80 Plus certified and has a 99% Active Power Factor Correction to ensure maximum efficiency.
The cables are extra long to work in the largest tower. They are fully sleeved for easy routing and bundling. There are four 8-pin PCIe power connectors so you can build up a CrossFire or SLI system using today’s high end video cards. There are also 8 SATA and 8 Molex connectors so you can connect multiple drives and peripherals.
Keeping it all cool is a temperature-controlled 140mm fan. Air is vented through the hexagon mesh back panel. The universal input accepts voltages from 90-264 so you no longer have to worry if the switch was in the right position.

*BEAST*
- Pros: Very good PSU for the money. The 12v rail and ampere is amazing for this PSU. Quiet, cables are nice and long. Tears through everything, of course not 3-way sli with 280's lol but you get the point. ummmmm.... its CORSAIR
- Cons: LOADS OF CABLES lol. Its not a bad thing for me, i got the Antec twelve hundred and the cable management is amazing, a lot better than most cases but if you have a mid tower case with no cable management options, i suggest you try a modular PSU because you may have a lot of trouble with all these wires.
- Other Thoughts: The people that take off 1 egg just because this PSU is not modular need to stop. Of course its not modular, look at the pictures, if you want modular so badly, go out and buy a modular PSU than, dont take off 1 egg just because something thats good is not modular, its very stupid and ignorant.
High quality power supply
- Pros: High quality power supply from the crinkle black finish to the tasteful yellow graphics. Corsair is the Mercedes of power supplies. It's quiet and has more then enough power for all but the most powerful systems.
- Cons: Not truly a con but there are just too many wires. If you have a small case be aware that cable management will be difficult.
- Other Thoughts: For the price the best power supply you can buy. This is my second Corsair unit and both have functioned perfectly. And Corsair has instituted a new web based rebate system that is effortless and quick.

Solid PS, good price
- Pros: Well packaged, high build quality PS. Solid rails. Runs my OCed i7 920 at 4ghz w/ Oced 5870 @1 ghz no problem.
- Cons: None
- Other Thoughts: Not an outright con, but my 3 volt rail is at 3.25 sometimes 3.23 at 500 watts or so. I hope this doesn't lead to failure at some point. Otherwise I love this PS, with a good mix of connectors, nice power cord, cool baggy, low price, 5 year warranty, I couldn't ask for more.
- Pros: Great power supply. Cost is relatively low considering the very high quality of it. Comes in a fancy drawstring pouch.
- Cons: None
- Other Thoughts: Powers my system with room to spare

Awful fan design.
- Pros: Good reviews, high amps on a single rail, plenty of cables, NOT modular, affordable, made by a respectable company.
- Cons: FAN DUMPS HOT AIR INTO CASE.
- Other Thoughts: Instead of the fan pulling air from within the case and exhausting it out of the back vent, like every other power supply I've ever had, Corsair has designed this fan to draw air from the back vent through the power supply and blow it down onto your CPU! I cannot understand for the life of me why Corsair would make such a stupid design choice on cooling for a high-watt, high-amp performance PSU that is predictably going to generate a lot of heat. In a case with a standard layout (PSU on top), this PSU is going to draw air from right above where your rear case fan is exhausting warm air, pass that warm air over very hot PSU components to heat it up even more, then blow that hot air down onto your CPU heatsink, then it will get exhausted through the rear case fan, partially sucked back up by the PSU vent and the whole cycle begins again!
If your temperatures go up across the board after switching to this PSU, don't be surprised.
-
Manufacturer Response:Actually no, the PSU fan is not intended to draw air into the case. You may simply have a unit with a defective fan. If it's drawing air in through the back of the fan grill, we'll replace it for you.
