850 W ATX 3.1 & PCIe 5.1 power supply
This unit delivers 850 watts through an ATX 3.1 and PCIe 5.1 platform with full modular cabling. It carries 80 PLUS Gold and Cybenetics Platinum efficiency ratings plus a Lambda A+ noise certification. A native 12V-2x6 connector is included for modern graphics cards. White finish and green accent connectors aid build identification.
Who this suits and who should look elsewhere
Builders assembling a white-themed system that needs a quiet, efficient 850 W unit with modern PCIe 5.1 connectivity will match this supply well. The Cybenetics Lambda A+ rating confirms low acoustic output for noise-sensitive environments. Systems requiring more than 850 W or a different form factor should consider other models. The semi-passive iCool mode benefits typical desktop loads but can be disabled for constant airflow.
ATX 3.1 & PCIe 5.1 ready with native 12V-2x6
The defining specification is the ATX 3.1 and PCIe 5.1 compliance paired with a native 12V-2x6 cable. This ensures direct, adapter-free power to current-generation graphics cards while meeting the latest transient-response requirements. Efficiency certifications and the 135 mm FDB fan support stable delivery at the rated 850 W.

Questions about this item
Will the native 12V-2x6 connector support my new PCIe 5.1 graphics card without an adapter?
Yes, the unit includes a native 12V-2x6 cable designed for ATX 3.1 and PCIe 5.1 graphics cards, removing the need for any adapter.
Does the semi-passive fan mode stay quiet during typical desktop workloads?
With iCool mode enabled the 135 mm FDB fan remains off at low to medium loads, and Cybenetics Lambda A+ certification confirms average noise below 20 dB.
Can I use only the cables my build requires to keep the case tidy?
The fully modular design lets you attach just the connectors you need, and the white finish with green accents helps verify each plug is seated correctly.
