Cons
- ✗ PCCOOLER lacks the RMA reputation of Seasonic, Corsair, or be quiet!

SpecPicks Verdict
SpecPicks scored PCCOOLER KN850 850W ATX 3.1 Fully Modular Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. PCCOOLER's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Key Features
- ATX 3.1 POWER FOR MODERN BUILDS: Built to the Intel ATX 3.1 standard with a PCIe 5.1 interface, this fully modular power supply is designed to manage changing system loads while keeping unused cables out of the build.
- 80 PLUS GOLD EFFICIENCY: 80 PLUS Gold certification supports efficient power conversion under typical loads. A 100–240V full-range AC input makes the KN Series suitable for compatible mains environments; use the included regional power cord.
- JAPANESE 105°C CAPACITORS: A Japanese bulk capacitor and 105°C-rated capacitors support stable long-term operation. The 120mm hydraulic-bearing fan uses thermal control to balance cooling and operating noise as load changes.
- NATIVE 12V-2X6 GPU CONNECTION: The included 12V-2x6 cable provides a direct PSU-to-GPU connection for compatible graphics cards. Insert both ends fully, keep the plug seated, and avoid tight bends near the connector.
- CHECK THE INCLUDED CABLES BEFORE ORDERING: Includes one 24-pin motherboard cable, two CPU cables, 3 PCIe 6+2-pin cables, 2 SATA cable sets, one 12V-2x6 cable, and the AC power cord. Use only the modular cables supplied with this PSU.
