Thermaltake Toughpower iRGB PLUS 850W Gold PS-TPI-0850F3FDGU-1 power supply

850W fully modular ATX power supply

This Thermaltake Toughpower iRGB PLUS unit delivers 850 W of continuous output through a single +12 V rail and carries 80 PLUS Gold certification for high efficiency. It targets builders who want digital monitoring, addressable RGB lighting and a fully modular cable set for cleaner cable routing in mid-to-high-end desktop systems.

Replaces older fixed-cable or lower-wattage units

The jump is worth it when a build needs 850 W headroom for multi-GPU configurations with six PCIe 6+2-pin connectors, twelve SATA power connectors and digital fan or lighting control via software. Older bronze-rated or non-modular designs cannot match the efficiency, cable flexibility or remote management this model provides.

Straightforward install with a few common pitfalls

The 160 mm depth fits most ATX cases, but verify clearance before mounting. Connect the 20+4-pin main, EPS and all required PCIe cables firmly; loose modular plugs are the main cause of no-post or instability. Use the supplied RGB and USB headers to enable SPM app control, and ensure the 140 mm hydraulic fan intake remains unobstructed for 50 °C ambient operation.
