Power supply unit DeepCool PS850G 850 W ATX 20+4 pin, FDB fan 92 mm, black

DeepCool PS850G is an 850 W ATX power supply unit designed for desktop PCs. It delivers up to 850 watts of continuous output power and accepts AC input from 100 to 240 V at 50/60 Hz. The unit uses a standard 20+4 pin ATX motherboard connector, comes in a black finish and fits standard ATX enclosures. Cooling is provided by a 92 mm fluid dynamic bearing (FDB) fan and the supply includes a set of cables for CPU, PCIe, peripheral Molex and SATA connections with specified cable lengths for motherboard and SATA leads.

Advantages

The power supply offers stable power delivery for typical desktop configurations and supports broad mains voltages for international use. A 92 mm FDB fan provides active cooling with reduced noise and longer bearing life compared with sleeve-bearing fans. Included multi-conductor cables and common connector types simplify system assembly and cable routing in standard ATX cases. The black finish and compact layout suit general-purpose builds.

Suitable for

• Standard desktop PC builds requiring up to 850 W total power
• Systems that use a 20+4 pin ATX motherboard connector
• Small- to mid-sized ATX enclosures where a 92 mm fan size is appropriate
• Configurations needing multiple SATA, PCIe and peripheral power cables

How to use

Install the DeepCool PS850G into a compatible ATX case using the standard PSU mounting points and screws. Connect the 20+4 pin ATX cable to the motherboard main power socket, then attach the CPU and PCIe cables to the processor power and graphics card as required. Route SATA and Molex cables to drives and peripherals, maintaining clear airflow paths to the 92 mm fan. Ensure AC power is provided by a correctly rated mains cable and that the supply is switched off before connecting or disconnecting internal power connectors.

Recommendations

For reliable operation, match the PSU capacity to the total system power draw including peak GPU and CPU demands, allow adequate case ventilation around the 92 mm fan, and use quality mains cabling and an appropriate surge protector or UPS where needed.
