850 W ATX Platinum power supply

The Razer Katana RC21-01840200-R3U1 is an 850 W ATX power supply with 80 PLUS PLATINUM certification. It uses a fully modular cable design and a single 140 mm fan with ARGB lighting. The unit operates on 100 - 240 V input and includes six 6+2-pin PCI-Express connectors. It is built for desktop systems that need efficient, high-wattage power delivery.

Suits builds needing full modular cabling

This unit suits builders who want a fully modular 850 W supply with platinum efficiency and addressable RGB lighting on the 140 mm fan. It fits standard ATX cases and provides six PCIe power leads for multi-GPU configurations. Buyers who need a lower maximum power rating or a non-modular design should look at other models. Systems requiring a different form factor or fewer PCIe connectors are not the target use case.

Six 6+2-pin PCIe connectors decide multi-GPU support

The six 6+2-pin PCI-Express connectors are the specification that determines whether this supply can power multiple graphics cards simultaneously. Each connector delivers either a 6-pin or 8-pin plug without adapters. If a build requires more than six such leads, this unit cannot meet the demand. Conversely, a single-GPU system may not use all available connectors.
