SilverStone Extreme 1200R Platinum 1200W - PSU, 80 Plus Platinum

The SilverStone Extreme 1200R Platinum is a 1200W, fully modular SFX-L power supply designed for compact PCs. It provides reliable power delivery for small form factor (SFF) workstations. The unit uses Japanese capacitors to maintain stable voltages under load. 80 PLUS Platinum certification confirms high efficiency, which helps reduce heat and energy waste. It reaches 91% efficiency during typical operation, offering high power output without a large physical footprint.

The fully modular design allows users to connect only the necessary cables, improving airflow inside the chassis. Cooling is handled by a 120 mm fluid dynamic bearing fan, which stops during low-load operation for silent performance. Fan noise peaks at 36 dB under heavy loads. Connectivity includes a standard 24-pin motherboard connector and dedicated CPU cables. The black metal enclosure is designed to suit dark-themed builds.
