Moving inside for a look at the actual circuitry. Japanese capacitors have been used throughout. These capacitors are known for being higher quality with 105C rating for better stability.

Our unit has a single 12v rail allowing 70A. This will of course feed our graphics card. In the testing stage of this review we will see how the TX850 V2 performs when powering GTX 480s in SLI.

Enthusiasts and general users often worry about the safety of their components when a PSU blows, overheats or suffers over-power, and rightly so. Many cheap, no-frills units will take components with them should they decide to give up. Crucial to the protection of our system are a set of protective standards that the TX850 V2 incorporates. Some of which I will briefly cover. We have the protection for under and overvoltage. This ensures all rails remain within the specification of 3.3v, 5v and 12v. Voltages should not spike under or over the rated values. The same can be said for other protective standards within the TX850 V2, which has temperature protection to prevent the unit from overheating, short circuit protection for each of the rails and power protection should the unit output more than the stated maximum wattage (850W). It's clear then we can place a good degree of confidence in this unit.
An overview of the internals
We've already mentioned the TX850 V2 features a 140mm fan. This is actually a Yate Loon D14BH-12 (double ball bearing). Rated at 48.5 dBA and 140CFM. Amongst cooling enthusiasts Yate Loon are renowned for having excellent pressure to noise performance results.
