Final Thoughts and Conclusions
The Thermaltake Toughpower XT Series 850W PSU delivered excellent voltage regulation with very good efficiency. The XT 850W is relatively quiet, runs cool during normal operation, and includes a good compliment of modular cables/connectors.  The main weakness we found was a relatively high level of AC ripple on the +12V DC output when the PSU was subjected to heavy loads.

The Thermaltake Toughpower XT Series 850W PSU is currently available and typically sells for around $239.99 USD, which is a little on the expensive side when compared with some other high-quality PSUs like the Antec Signature 850W ($239.99) or the Corsair 850HX ($194.99) that manage to keep the AC ripple under control.
