Compact size design

After creating the smallest 850W full modular power supply in 2016, SilverStone has again upped the record for smallest retail PSU with full modular cables at 1000W and 1200W respectively with 150mm (W) x 86mm (H) x 140mm (D) dimensions.  This allows for nearly unlimited possibility in small form-factor PCs.

Designed for 80 PLUS Platinum level of efficiency to reduce wasted heat and save on electricity

Built-in 120mm fan has excellent airflow and low noise, perfect for quiet home or office use

±3% regulation and low ripple & noise performance for high stability

Strider Gold S PSUs are the first power supply models in the world to include flat 24pin cables. This cable offers much greater flexibility for tighter folding and superior cable management

140mm depth sets a new standard for high wattage PSUs with modular cables

100% modular cable design for easy removal

Powerful single +12V rail design, perfect for future high-end component upgrades or overclocking

The included FF122 fan filter can help reduce dust buildup; and with its built-in magnets, it’s also extremely easy to attach and remove.

Higher efficiency High efficiency with 89%~92% across all loading conditions from 20% to 100% loading. Saves power, saving you money on your electrical bill, less heat, less noise.
