Fuente de alimentación DeepCool PN850M 850 W ATX 20+4 Pin, 80 PLUS Gold, blanco

The DeepCool PN850M 850 W is a white ATX power supply unit designed for desktop PCs that require high and stable power delivery. It delivers 850 W total output with 80 PLUS Gold efficiency (~90%), accepts 100–240 V AC at 50/60 Hz, and provides a 20+4 pin ATX motherboard connector. The unit features a dynamic 120 mm FDB cooling fan and multi-length SATA cabling to suit common PC layouts. PN850M implements modern topologies and protections to support contemporary systems including PCIe 5.1 devices and ATX 3.1 specifications.

Advantages

The PN850M combines high efficiency with robust electrical design: native ATX 3.1 compliance, support for PCIe 5.1 power delivery, and a DC-to-DC topology with a main Japanese electrolytic capacitor for reliable voltage regulation and ≥16 ms hold-up time at heavy load. It includes active PFC, full-bridge SRC LLC conversion and multiple built-in protections (OPP, OVP, SCP, OTP, OCP, UVP, NLO, SIP). The 120 mm dynamic FDB fan adapts speed to cooling needs, while the white finish and modular cable layout simplify installation in modern builds. DeepCool backs the unit with a long limited warranty for extended peace of mind.

How to use

Install the PN850M into a compatible ATX chassis following the case and motherboard manual: secure the PSU in the mounting area, connect the 20+4 pin ATX cable to the motherboard, attach the dedicated PCIe 12V-2x6 cable(s) to the GPU as required, and distribute SATA and peripheral connectors to storage and accessories. Connect the AC mains cable to an appropriate mains outlet. Ensure correct cable routing and adequate airflow so the 120 mm fan can regulate temperature. Before powering on, verify that all connectors are fully seated and that the PSU switch (if present) is set to the on position.

Recommendations

For reliable operation, pair the PN850M with systems whose combined continuous power draw stays comfortably below 850 W to maintain efficiency and component longevity. Allow sufficient case ventilation around the PSU fan, use the supplied high-quality PCIe cable for GPU power, and keep firmware and BIOS settings on the motherboard up to date when using the latest ATX 3.1 and PCIe 5.1 hardware.
