Seasonic FOCUS GX ATX 3.1 v5 PSU Adds Cybenetics Platinum Rating

Seasonic has updated its FOCUS GX power supply lineup with the new ATX 3.1 v5 series, bringing higher efficiency standards to a familiar compact form factor. This refresh matters to builders because the new models now carry Cybenetics Platinum certification across the board, a step up from the previous generation's mixed ratings. The update ensures that systems built with these units meet stricter power quality benchmarks without requiring a larger chassis.

New models retain compact 140mm chassis while upgrading efficiency standards

The FOCUS GX ATX 3.1 v5 and its white counterpart, the FOCUS GX White ATX 3.1 v5, retain the 140mm chassis size that defines the series. This compact design supports the latest ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with modern graphics cards. The units ship with native 12V-2×6 connectors, which simplifies cabling for high-end GPUs while maintaining a clean internal layout.

Specifications

• Efficiency Certification: 80 PLUS Gold, Cybenetics Platinum
• Form Factor: ATX, 140mm chassis
• Warranty: 10 years
• Fan Type: 135mm FDB (Fluid Dynamic Bearing)
• Connector: 12V-2×6

Seasonic offers the new series in three wattage options: 750W, 850W, and 1000W. All models utilize a 135mm fluid dynamic bearing fan to manage heat and noise. The company has improved noise certification significantly, with the 1000W and 850W models reaching level A, while the 750W model achieves the quieter A+ rating. These units also feature full modular cabling and OptiSink thermal design for stable operation.

We touched on Seasonic Launches Focus GX-1000 ATX 3.1 in our earlier Seasonic coverage. The new v5 lineup builds on that foundation with enhanced efficiency and noise profiles. Seasonic has not yet announced pricing or specific release dates for these power supplies. Builders should monitor official channels for availability updates as the company prepares to launch the series.

The FOCUS GX ATX 3.1 v5 series represents a targeted upgrade for users seeking compact, high-efficiency power delivery. The retention of the 140mm form factor allows for easier installation in smaller cases without sacrificing power headroom. Users waiting for the official price and release window can expect a product that prioritizes quiet operation and modern connectivity standards.
