A N EW S TANDARD
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 For an updated list of
models supported please visit www antec com/cp850
S TANDARDS AND F EATURES
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
S YSTEM P ROTECTION
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
S PECIAL Q UIET C OMPUTING ™ 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® C ERTIFICATION
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

The CP-850 power supply distributes power on separate rails To see the output capacity and
regulation for each different voltage, see Table 1

A DVANCED H YBRID C ABLE M ANAGEMENT
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
T HE M ODULAR C ABLE J ACKS
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

+12 V OLT R AIL D ISTRIBUTION
The CP-850 uses four separate +12V power rails 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

I NSTALLATION :
1. You will n d to r mov th standard PSU adapt r plat from th Ant c cas to allow th larg r PSU to fit.
2. Install th CP-850 PSU into your cas with th four scr ws provid d.
3. Conn ct th 24-pin main pow r conn ctor to your moth rboard. If your moth rboard us s a 20-pin
conn ctor, d tach th 4-pin attachm nt on th 24-pin conn ctor.
Note Th d tachabl 4-pin s ction cannot b us d in plac of a 4-pin +12V conn ctor.

4. Conn ct th 8-pin or 4-pin conn ctor for th CPU. If your moth rboard has an 8-pin sock t with a cov r on
som of th op nings, w r comm nd that you r mov th cov r and us th 8-pin conn ctor.
Note Pl as also r f r to your moth rboard us r’s manual for any sp cial instructions.
5. Conn ct xtra cabl s from th cabl pack to th sock ts on th pow r supply only if n d d. If you ar going
to plug th PCI-E cabl s into th PSU, th y should go into th r d sock ts. If th r d sock ts ar not b ing us d
for PCI-E, th n th y can b us d for any oth r typ of cabl suppli d in th pack that accompani s th PSU.
6. Conn ct th AC pow r cord to th pow r supply AC inl t. B sur to us th h avy-duty cord suppli d with
your CP-850.

7. PCI-E graphics cards us diff r nt amounts of pow r. For som , a singl 6-pin conn ctor is suffici nt, and th
hardwir d conn ctor is th pr f rr d choic . Mor pow rful cards us multipl conn ctors, including th
advanc d 8-pin PCI-E conn ctor. Th 8-pin PCI-E conn ctor on your CP-850 can b us d as ith r a 6- or 8-pin
conn ctor.
8. Hard driv s, optical driv s (CD/DVD/BluRay™), and oth r acc ssori s will us ith r th old r 4-pin Mol x
conn ctor or th n w r 15-pin SATA conn ctor. 4-pin Mol x conn ctors hav two black wir s, a y llow, and a
r d. Th SATA conn ctor has an additional orang pow r wir .
9. Wh n you hav all th conn ctions s cur d, turn th switch on th PSU to th “|” position. You ar now r ady
to pow r up your comput r.
