Designed to deliver the clean, stable power your system deserves

When you build or upgrade your own system, you want a power supply that meets both your power requirements and your exacting standards for performance and noise. The entire Enthusiast Series TX V2 family has been designed to do just that. With any TX V2 PSU, you'll find the right balance between price and the features you want: high efficiency, tight voltage regulation, low ripple and noise, and thermally-controlled fan speed.

Unlike many "value-oriented" power supplies, the entire range of TX V2 power supplies are designed to continuously deliver their rated power, all the way to 50°C ambient temperature. And with the tight voltage regulation and low ripple and noise that Corsair's Enthusiast Series in known for, you'll get clean power too. No more random crashes caused by dirty or insufficient power!

All TX V2 power supplies deliver up to 85% efficiency, feature a single +12V rail for simple installation, and are compatible with the latest Intel and AMD platforms, as well as NVIDIA and AMD multi-GPU configurations. They are even ErP ready, so your system can use as little as 1W of power in standby mode (when used with an ErP-compliant motherboard).

Corsair Enthusiast Series TX850 V2 Features:

  • Conforms to the latest ATX12V v2.31 and EPS 2.92 standards, and is backward compatible with the ATX12V 2.2 and ATX12V 2.01 standards
  • A dedicated single +12V rail offers simple configuration and maximum compatibility with the latest graphics cards and other components
  • An ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature
  • 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

    Active Power Factor Correction (PFC) with PF value of 0.99

850TX V2 wins award at Hardware Secrets

"In this review, we discovered that the Corsair TX850 V2 is internally identical to the XFX PRO 850 W, and the only differences between the 850 W and the 750 W models are the use of more powerful switching transistors and one additional Schottky rectifier in the 850 W model. Although the TX850 V2 is nicely priced (USD 135 or USD 125 after mail-in rebate), the XFX PRO 850 W costs less (USD 120 or USD 110 after mail-in rebate). Since both power supplies are the same, right now it makes more sense to buy the model from XFX. Interestingly enough, the opposite occurs with the 750 W model; the TX750 V2 is a little cheaper than the XFX PRO 750 W. Who said, “Competition isn’t healthy?” "

Hardware Heaven gives the 750TX V2 and 850TX V2 the Gold award

"When it comes to the build quality and design of Corsair PSU's it is always very hard to find any fault and the TX V2 continues this trend. We get a lovely high quality finish on the unit and care has been taken to sleeve the wires well into the PSU where they are tied in place. Important components are all high quality and secured well inside with adhesive used where necessary and the spacious design allows for good airflow around the unit. We also noted that Corsair have taken the design to an extra level "

Corsair TX850 V2 wins Silver award at Overclockers Club

"The Corsair TX750 V2 750W and TX850 V2 850W are still very good power supplies and I'm sure they will still remain popular in the PC enthusiast community but I feel the performance could of been improved further second time around. The Corsiar V2 units did perform very well and are an improvement on their predecessors so they still come highly recommended and I have no hesitation in awarding them the OCC Silver award."

TweakTown reviews the Corsair TX850 V2

"Corsair has done a great job with the TX850V2. They took all of the good of the original TX850W and made most of the improvements needed to produce another rock solid power supply. While the TX850V2 produces solid numbers for voltages, noise, and efficiency"
