Cable Arrangement
Designed around current-generation hardware
The ATX 3.1 design includes a 16-pin graphics cable rated for up to 600W. GPU-First voltage sensing works with the supported 16-pin connection to prioritize graphics-card voltage feedback; it does not apply to 8-pin GPU cables.
See power use from either side
The magnetic OLED display shows power draw and can move to either side of the unit. That gives you flexibility to install the PSU with its fan facing up or down while keeping the display visible in a suitable case.
Cooling with control
GaN MOSFET technology, ROG heatsinks and an aluminium enclosure support thermal management. The 0dB mode stops the fan at suitable low loads, while Turbo Mode uses a fan profile intended for demanding operation. Cybenetics Lambda A++ certification reflects the unit's tested acoustic performance.
Plan a compatible build
Allow for the 190mm PSU depth and cable clearance in your case. Match total power and connectors to your processor, graphics card and other components. Compare power supplies, explore graphics cards and choose a compatible motherboard.
Use the Supplied Modular Cable System
Connect the required motherboard, CPU and GPU leads using the cables specified for this exact power supply. Keep component-side connectors matched to their intended devices, and do not assume modular cables from another PSU use the same wiring.
Size Power for the Finished Computer
The unit’s total rated output is 1200 watts, including the stated 1200-watt maximum on the 12-volt rail. Plan capacity around the processor, graphics card and other components while checking the case depth, connector requirements and cable routing.
Plan Power, Connectors and Case Fit
Check the system power requirements, required connectors and case clearance for the exact unit. Use cables approved for that specific power supply; modular cables are not universally interchangeable. Compare related options such as ASUS ROG Thor 1000W EVA Edition Power Supply, Platinum II or Corsair RMe Series RM750e Fully Modular Low-Noise Power Supply, keeping the exact model and configuration in the decision. For the wider setup, explore LIAN LI O11 Dynamic XL Full Tower Case, USB 3.0 and check the connection, size or mounting requirements before pairing accessories.

Frequently Asked Questions
How much space does it need?
190 × 150 × 86 mm. Allow additional space for the modular plugs and cable routing in the case.
Does every cable provide GPU-First sensing?
GPU-First sensing applies to the supported 16-pin graphics connection. It does not apply to 8-pin GPU cables.
What is the native graphics power connection?
1 × PCIe Gen 5.1, up to 600 W. Match the GPU requirements and fully seat the cable; a 600 W cable rating does not change the complete PSU’s 1200 W total output.
Can I reuse modular cables from another PSU?
Use the cables specified for this exact power supply. The component-side connector shape does not establish the wiring compatibility of another PSU’s modular cables.
