Thermaltake Smart Pro RGB 850W Power Supply Review - Frag-harder RGB lighting is all the rage, and so of course we are now seeing those in PSUs too. Thermaltake has a healthy 850 watt PSU here for review today that actually hits the sub-$100 mark by 1 cent. Fully modular with great DC output; is there anything not to like? You can turn the RGB off. So there's already one big value plus! And a 7 year warranty.
