Compact 850W ATX power supply

This Thermaltake Toughpower PF1 unit delivers 850W through a single +12V rail and carries 80 PLUS Platinum certification for up to 92% efficiency. Its 140mm depth fits tight chassis while the fully modular design uses low-profile flat black cables for clean routing. A 120mm hydraulic bearing fan runs in a smart zero-fan mode for quiet operation.

Upgrade from lower-efficiency or longer PSUs

Replacing a bronze or gold-rated unit with this Platinum model cuts waste heat and lowers electricity draw under load. The shorter 140mm depth frees space behind the motherboard tray for easier cable management in compact cases. The jump is worthwhile when efficiency, noise and case clearance matter together.

Suits high-efficiency builds in small cases

Builders who want Platinum efficiency, a single strong +12V rail and six 6+2-pin PCIe connectors in a 140mm-deep enclosure will benefit. Systems needing more than 850W or a larger fan for passive cooling at higher loads should look at higher-wattage or larger-form-factor units instead.

Questions about this item

Will the 140 mm depth fit in a compact ATX case?

The unit is 140 mm deep, 86 mm high and 150 mm long, so it fits most cases that accept a standard ATX supply with room for cable routing behind the motherboard tray.

Which cables must stay attached during installation?

No cables are fixed; the supply is fully modular. Connect the 24-pin motherboard cable, the required 6+2-pin PCIe cables for your graphics card, and only the SATA power leads you need.

How often should the 120 mm hydraulic bearing fan be cleaned?

Dust the fan intake every 6 to 12 months with compressed air; the hydraulic bearing is sealed and does not require lubrication.
