PN850M NATIVE ATX3.1 FUTURE PROOF

With the ability to provide twice the total system power for 0.1 ms, random power spikes will never be an issue. The PN850M will provide stable and consistent power for legacy and next-generation PCs for the foreseeable future.

GRACEFUL GOLD

80 Plus Gold certified to meet a high level of power efficiency under 90% of typical loads. Each unit is also rated Gold by Cybenetics.

POWER YOU CAN TRUST

Through the use of a main Japanese electrolytic capacitor, active PFC, full-bridge SRC LLC, and a DC-to-DC topology, the PN850M can keep the hold-up time to ≥ 16 ms under a high load of 80%.

PCI-E 5.1 POWER

Equipped with a high-grade 105C-resistant 16AWG copper-core embossed 12V-2x6 cable, the PN850M provides up to 600W for modern GPUs.

DYNAMIC FDB FAN

The PN850M comes equipped with a dynamic 120mm FDB fan that will adjust its speed based on the cooling needs of the PSU.
