ASRock Phantom Gaming PG-850PSF 850W - PSU, 80 Plus Platinum

The ASRock Phantom Gaming PG-850PSF is an 850W SFX Platinum power supply designed for small-form-factor PCs. It converts mains AC power into stable DC rails and meets the ATX 3.1 specification, ensuring compatibility with current motherboards. With an 850W capacity, the unit supports power-intensive processors and graphics cards. The unit is Platinum-certified, operating at 90.37% efficiency to reduce heat, and uses active power factor correction to stabilise delivery under load.

Cooling is managed by a 92mm fan, which includes a silent mode that stops rotation during low loads to minimise noise; under typical usage, the unit produces 14.25 decibels. The fully modular design allows users to connect only the cables required for their configuration, which improves airflow in compact cases. The dark finish is designed to blend into most system interiors. The unit is rated for reliable operation in temperatures between 0 and 50°C.
