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. For an updated list of models supported please visit 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. 80 PLUS® CERTIFICATION 80 PLUS® certification is the most widely recognized independent standard in power supply efficiency. An 80 PLUS® certified power supply uses less energy and generates less heat to stay cooler, run quieter and last longer. The CP-850 has been 80 PLUS® certified to be at least 80% efficient at a wide range of operating loads; this will lower your operating costs and help protect the environment. Source: 80 PLUS® Verification and Testing Report NVIDIA™ SLI™-READY CERTIFICATION Antec’s CP Series power supplies are NVIDIA™ SLI™-Ready certified for use with multiple high-end graphics cards for superior parallel graphics processing. POWER OUTPUT The CP-850 power supply distributes power on separate rails. To see the output capacity and regulation for each different voltage, see Table 1. TABLE 1 Output Voltage Maximum Load Regulation Ripple & Noise +3.3V 24A ±5% <50 mV +5V 30A ±5% <50 mV +12V1 22A ±5% <120 mV +12V2 22A ±5% <120 mV +12V3 25A ±5% <120 mV +12V4 25A ±5% <120 mV –12V 0.6A ±10% <120 mV +5VSB 3A ±5% <50 mV ADVANCED HYBRID CABLE MANAGEMENT The CP-850 uses Advanced Hybrid Cable Management. Cables that are important or mandatory are permanently connected to the PSU for the highest quality power delivery. There are modular jacks on the back of the PSU to add additional cables as needed. Using only the cables you need will reduce clutter and improve airflow inside your case. For the list of connected and optional cables, see Table 2. THE MODULAR CABLE JACKS There are two black jacks and two red jacks on the back of your CP-850 PSU. These jacks are for the optional cables that come with your power supply. The black connectors are used for Molex or SATA cables. Because of the high power requirements of modern graphics cards, the red ones are set up to handle their needs. If you are not using the red connectors for PCI-Express connectors, then you can use them for additional Molex or SATA cables as needed.

Different connectors are hooked up to separate circuits to aid in the balanced distribution of power between devices in your computer. The engineers have allocated the rails to different connectors, as shown in Table 3, to prevent voltage sags in one device due to sudden demands for power by another device.
