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.
