Virtual-Hideout posted a review on the In Win Commander 850w Power Supply

Based on the same standards, the In-Win Commander 850 Watt Power Supply can easily handle your loftiest power requirements. At 100% load, the PSU produces power rails just above spec which earns it a spot on my Extreme Gamer Approved list. The all important 12V rails remained 12.07 or above which is all you can expect from this mean, green gaming machine. However, I did manage to find an extra 35 Watts under that militant exterior which was still supported by at least 11.97 Volts.
