ST55F-GS

■ Compact design with a depth of 140mm for easy integration

■ 80 PLUS Gold certification

■ 100% modular cables

■ 24/7 continuous power output with 40℃ operating temperature

■ Class-leading single +12V rail

■ Strict ±3% voltage regulation and low ripple & noise

■ Silent running 120mm fan with 18dBA minimum

   
Remark

(1) Designed for 80 PLUS Gold level of efficiency to reduce wasted heat and save on electricity.
(2) Built-in 120mm fan has excellent airflow and low noise, perfect for quiet home or office use.
 
     
     
(3) ±3% regulation and low ripple & noise performance for high stability.  (4) 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.
 
     
(5) 140mm depth sets new standard for high wattage PSUs with modular cables.  (6) 100% modular cable design for easy removal in a case with cable routed and tied down.
 
     
(7) Powerful single +12V rail design, perfect for future high-end component upgrades or overclocking.

● ST55F-GS is 100% modular cable design power supply, and the 24 pin connector design is 18+10pin to 24pin (20+4) +4 pin. Therefore, the PP05-E and PP06 24pin cables can’t be used in ST55F-GS.
● Specifications presented on this page contains most recent revisions and may differ from those printed on retail boxes or manuals.
