Thermalright expands power supply lineup with ATX 3.1 compliant GM Series

Thermalright has expanded its power supply lineup with the introduction of the GM Series, featuring fully modular, 80 PLUS Gold-certified units. Available in 650W, 750W, and 850W capacities, the new series targets modern gaming and enthusiast configurations by adopting compact ATX form factors alongside updated hardware compatibility standards.

According to the company, the GM series models (via Vortez) comply with Intel's ATX 3.1 specification, enabling them to handle up to 200% power excursions. The two higher-capacity units also include a native 12V-2×6 connector to support PCIe 5.1 graphics cards. In contrast, the GM-650 comes with conventional PCIe power connectors instead. Colour options vary by model: the GM-750 and GM-850 are available in black and white, while the GM-650 is available only in black.

Thermalright builds the entire GM Series using a 150mm form factor equipped with a 120mm cooling fan. Internal components include a 105°C-rated Japanese primary capacitor, an LLC resonant circuit, and a DC-to-DC circuit design. Universal 100-240V AC input support is standard across the family. Safety features include a comprehensive suite of protection circuits, specifically OPP, OVP, OTP, OCP, SCP, and UVP. Thermalright backs the new GM power supplies with a five-year warranty.

KitGuru says: Thermalright continues to expand its component ecosystem, offering an accessible entry point into the ATX 3.1 standard with its new GM series.
