Toughpower GF3 850W ATX 3.1 power supply

This fully modular unit delivers 850 W of continuous power and meets the ATX 3.1 design standard. Japanese main capacitors and a single +12 V rail provide stable output for modern desktop builds. The 140 mm hydraulic bearing fan uses a Smart Zero mode to stay off at low loads. Eighty Plus Gold certification confirms high efficiency across typical workloads.

Sustained load behaviour and noise profile

Under continuous demand the power supply maintains its rated output while the fan ramps gradually to meet thermal needs. Cybenetics A- noise certification indicates quiet operation even when the system draws heavy current for extended periods. Full protection circuits including OCP, OVP, UVP, OPP, SCP and OTP guard components during prolonged stress. The 150 mm chassis depth fits standard ATX cases without restricting airflow.

Native PCIe 5.1 12V-2x6 connector

Two native 12V-2x6 cables each support up to 600 W, enabling direct connection to current-generation graphics cards without adapters. The matcha-coloured H++ connector reveals a visible colour cue only when the plug is not fully seated. Flat modular cables with colour-matched ends simplify routing and improve case aesthetics. This connector specification is the decisive factor for GPU compatibility.

Perguntas sobre este artigo

How loud is the 140 mm hydraulic-bearing fan during continuous 24/7 operation?

The unit carries a Cybenetics A- noise rating and the Smart Zero Fan mode keeps the 140 mm hydraulic-bearing fan idle until load demands cooling, so all-day running stays very quiet.

Which motherboard and GPU connectors must my build already provide for this fully modular 850 W ATX 3.1 unit?

You need a 24-pin ATX socket, two 8-pin EPS (4+4) CPU headers, and the new 12V-2x6 (12+4) PCIe 5.1 connector; all cables detach so you only plug what the board and card require.

Will the single +12 V rail and 150 mm depth work with an older Haswell-era motherboard and standard ATX case?

Yes — Haswell support is confirmed, the single +12 V rail delivers the full 850 W to legacy components, and the 150 mm length fits most traditional ATX chassis.
