Efficiency
Despite the DeepCool DQ850-M-V2L officially being gold efficiency rated (up to 91.9%) our testing found that the efficiency rating was substantially higher than this. Practically falling into the remits of Platinum efficiency, but simply, in our testing this performed far better than the packaging and features suggested. And, by a pretty huge margin too!
Achieving a minimum of 91.6% and a maximum of 94.9%, this was amazingly good!
PFC (Power Factor Correction)
Although starting off quite low at 20% (which is perfectly normal by the way) the PFC rating ramps up considerably the more you ask this power supply to work. Achieving over 0.95 at 100%, it clearly indicates that the correction rate is excellent!
Voltage Regulation
When it comes to voltage regulation, you ideally want to see two factors present. Specifically, consistency and and a solid average deviancy. In this regard, the DeepCool DQ850-M-V2L is truly fantastic.
As you can see below, the results provided are remarkably consistent in many areas and, where they are not, the average deviancy works out to provide a very solid result.
