Antec CP-850w


When it comes to PSUs, for years now the ATX unit has taken centre stage with little thought going into producing a different form factor. However, Antec have changed all this and decided that it is time for a revamp. Their new form factor, christened the CPX, is a lot bigger so as to allow more room for the guts and allow a less restrictive airflow. Electrically, it’s just an ATX power supply but unfortunately the size means that a limited selection of cases can take the unit – unless of course you’re into modding. Antec clearly hope the new form factor catches on and their first model is the CP-850, but is all the hype really justified? Let’s have a look… 

Antec’s Take on the CP-850

‘The CP-850 features a unique design with an advanced cooling system, exclusively compatible with some of Antec’s most cutting-edge Gamer and Performance One enclosures, including the Twelve Hundred, P183 and P193. By breaking the mould of standardized power supply size restrictions, the CP-850 design is able to provide an excellent price-to-performance ratio. A silent rear 120mm Pulse Width Modulation (PWM) fan and dual PCB layout also ensure optimal cooling performance and reliability.’
