CP-850 POWER SUPPLY
ANEW STANDARD
The CP Series is Antec’s exclusive new high-performance power supply unit (PSU). It balances size, cost, and plenty of quality power by combining cutting-edge technology with a new form factor. The design features in this expanded form factor allow for improved component selection, better circuit board layout, more room between components for airflow, and a straight-through air path that takes full advantage of the large fan. Larger fans move more air at lower RPMs and make less noise. Antec’s new CPX form factor has better airflow than any standard size PSU that uses a large fan. The CPX form factor is exclusively compatible with Antec’s cutting-edge Gaming and Performance One cases, including the Twelve Hundred, P183 and P193.

STANDARDS AND FEATURES
The connectors and power specifications of the CP-850 PSU are all compatible with the ATX12V v2.3 and EPS12V v2.91 specifications. The CP-850 features Universal Input, which automatically senses when you connect the power supply to any AC power source between 100~240V without setting a voltage switch. This power supply also features Active Power Factor Correction (Active PFC), which improves the power factor value of the power supply by altering the input current wave shape, helping power transmission across the grid.
SYSTEM PROTECTION
A variety of industrial-grade safety circuitry will help protect your computer: OVP (Over Voltage Protection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Sometimes the PSU will “latch” into a protected state. You will need to power off the PSU and clear the fault before it will function again. There are no user-replaceable fuses in your CP-850.
SPECIAL QUIET COMPUTING™ PWM FAN
Another innovation in your CP-850 is the use of pulse width modulation (PWM) fan technology. A PWM fan can spin much more slowly and be quieter than a voltage- controlled fan. The PSU uses a PWM fan that can spin as slow as 390 RPM or as fast as 2600 RPM, depending on load and ambient temperature. It should be nearly inaudible when your computer is idling, and the PSU will vary the fan speed depending on the load of your computer. The location of the PSU fan also helps to reduce the sound emitted by your computer.
