NZXT C-Series C850 & C1000 GOLD Power Supply Reviews

Efficiency

With the efficiency testing, things get off to a bit of an odd start. Not because the results are bad. Quite the contrary in fact. The results are excellent and almost to the point that we’re having a difficult time knowing whether we can 100% guarantee their accuracy.

You see, both the NZXT C850 and C1000 are 80-Plus Gold efficiency rated. A reasonably high but not exactly mind-blowing certification. For both power supplies, however, it’s no understatement to say that the results provided in our testing go way beyond that remit. In fact, with results (for both PSUs) averaging about 95%, this is more in the realms of Titanium (2 tier levels higher than Gold).

Put simply, either these power supplies are truly excellent in terms of efficiency, or some quirk in our testing provided results about 2-4% higher than we were expecting. – And even if its the latter, this is still incredibly impressive stuff!

PFC (Power Factor Correction)

Similar to the efficiency ratings, the PFC score provided in our testing is exceptionally good and possibly to the point that, once again, we have to question whether something unusual is happening with these particular PSUs and our tester. – In this regard though, and similar to the efficiency scores, we have seen similarly good results before and, as such, we would be willing to say that in a similar fashion, while these might not 100% be the actual scores provided, they have to be very close indeed!

Voltage Regulation

Based on the results so far, you’re probably already more than a little aware that we have more than a few doubts as to whether these power supplies are happily coordinated with our tester. In something that seems to heavily back up the exceptionally positive results so far, however, the voltage regulation for both the NZXT C850 and C1000 GOLD are excellent!

With incredibly low levels of deviancy, and amazingly consistent results across the various load outputs. At this point, we’re very much erring towards both of these power supplies being incredibly impressive in their performance!
