Antec CP-850 850W Power Supply Review

Antec has always been known for making very reliable power supplies. They have done something a little interesting with their CP-Series power supplies though. They are designed differently so they are larger than most power supplies, which means they will only fit in certain cases. Those cases include Antec’s Twelve Hundred, P183, and P193. The larger size does allow for a better internal design, but is that worth limiting what cases you can put the power supply in? Antec has sent us their 850W version of the CP-Series, let’s put it to the test and see if it’s worth it!

Special thanks to Antec for providing us with the CP-850 850W Power Supply to review.
