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.

Questions about this item

What case depth is needed for the 160 mm length of this PSU?

The unit measures 160 mm long, so any ATX case with at least that much clear depth behind the motherboard tray will accept it.

How do you connect the 6 PCIe 6+2-pin cables without mixing them with the 12 SATA leads?

Plug only the labelled PCIe cables into the GPU sockets on the modular board; the SATA cables use separate ports and cannot fit the PCIe headers.

When should the 140 mm hydraulic bearing fan be cleaned or replaced?

Clean the fan blades with compressed air every 6–12 months; replace the fan only if bearing noise appears or airflow drops noticeably.
