Corsair TX Series is designed for hardcore PC gamers, performance enthusiasts and anybody who appreciates a combination of high performance standards and affordability. Efficiency is important - less heat is generated, so your system stays cool and your energy bill is lower. TX Series PSUs are 80 PLUS certified to operate at a 82 percent or better efficiency, even at maximum load. The 140mm double ball-bearing fan automatically adjusts its speed to deliver the proper amount of airflow, so high-performance power delivery isn't at the expense of noise. In fact, when you're just surfing the web, doing light office applications or otherwise keeping your TX Series PSU at less than 50 percent load, the fan doesn't even spin.The fan doesn't even spin at low loads, so you'll enjoy virtually silent operation. And when you're pushing it hard, the double ball bearing 140mm fan adjusts its speed according to temperature, so it only works as hard as it needs to. A single high-amp +12V rail offers simple configuration and greater compatibility with the latest graphics cards and other high-draw components. Power ratings are for continuous delivery - not peak. Over-voltage, under-voltage, over-current and short-circuit protection provide maximum safety for your critical system components.Complies with the European Union ErP Directive (2009/125/EC) so the power consumption of the whole system, in either standby or off mode, can be less than 1W when used with a properly configured, ErP-compliant motherboard. A five year warranty and lifetime access to Corsair's legendary technical support and customer service. Safety Approvals: cTUVus, CE, CB, FCC Class B, TÜV, CCC, C-tick.

"140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature"
No, my big FSB was low noise. This thing is not even close. Sounds like the old cheap one I had on my P4 before it went out and I got the 700W FSB. Buy it for the rest of the build quality. Don't expect it to be any quieter than the average one. After installing this, I decided to forget the idea of building a quiet computer.
SDDs making noise. NZXT Vulcan fan rattling at the top. Power Supply not as advertised. So I just used the stock Intel CPU cooler and got a loud overclocked GTX580 to go with my (now) hurricane of a PC. I probably should have gone for an expensive water cooling solution from a boutique, but at least I know how to replace all the parts.
One thing to keep in mind, the fan on the power supply does not run until a specific load is being used. This worried me because I thought that the fan was not operational and that the power supply would overheat. After contacting support, they informed me that this is normal operation for their power supplies. Corsair just designed a power supply that doesn't require much cooling at a standard load.
My only problem with this power supply is the amount of connectors it has. It would be better if they had a connection at the power supply itself so you could use only the amount of connectors you need. With all the connectors, I could see how a system could be filled with messy cables. Luckily, I bought the corsair graphite series case that has a separate compartment for unused cables.

Usually 600W would be enough for this set-up. Opted to place a higher capacity PSU for peace of mind and maybe for future upgrading. PSU gave me a nightmare instead. Been reading some of the comments from other customers about the tech support from Corsair. I have submitted 2 tickets in the customer portal already and still waiting for their snail pace reply. I give this product 1 star. Customer service so far 0 stars.
Finally got through customer service. After not receiving any reply through their customer service portal. I tried to message them through their facebook page. To my surprise someone answered! Asked for my ticket number and made the ball rolling. Technician replied to my ticket through customer portal, gave them the copy of my proof of purchase, printed the return label, sent the blown PSU to them (you need to pay for shipping). Called the customer service to follow up my replacement (waited in line for 20 minutes). Finally received my TX850M (they ran out of TX850 V2 they said...?) 3 weeks after my first attempt contacted them. So if anybody out there is trying to reach customer service through the portal and failed. Try there facebook page. Calling customer service also requires patience (20-30 minutes wait time). Corsair needs to invest more to adding more man power to their customer service. Seems like only 10 people working their to cater everybody!.
I hope that Corsair will honor the five year guarantee, but since they are not completely dead, I have my doubts.
November 09 2015: 3 years into a 5 year warranty and the second unit has failed. Corsair will most likely honor the warranty again, but the only warranty that interests me is one I never have to exercise. The cost of RMAs is considerable and will have added about $50.00 to the cost of this power supple making it terrible value for cost. Not to mention all the hassle involved with packaging and shipping broken junk. I have also been similarly disappointed by an expensive corsair keyboard. Corsair is no longer a supplier I will choose by default
