Strider Platinum series     ST85F-PT



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

￭ High efficiency with 80 PLUS Platinum 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

￭ Ultra silent 120mm fan with intelligent semi-fanless operation

   
         As desktop computers continue to advance toward ever more efficient and smaller designs, SilverStone is helping to drive the efficiency movement by releasing the Strider Platinum series of power supplies. Created to be the smallest fully modular ATX power supplies with 80 PLUS Platinum efficiency, they are also incredibly quiet with the ability to run in fanless mode. If the loading condition is below 20%, the fan in the power supply can remain off for silent operation during idle or low powered computing activities. Other great features inherited from previous Strider series include ±3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. For those looking to build highly efficient systems in small footprints, the Strider Platinum is definitely the best choice.

  

Remark
 
Designed for 80 PLUS Platinum level of efficiency to reduce wasted heat and save on electricity.   100% moudlar cable design for use with short cable kit such as SilverStone’s PP05-E or for easy removal in a case with cable routed and tied down.
 

  
 
Flat cables have much greater flexibility to allow for tighter folding and management of cables.   140mm depth sets new standard for high wattage PSUs with modular cables.
 

  
 
Powerful single +12V rail design, perfect for future high-end component upgrades or overclocking.   ±3% regulation and low ripple & noise performance for high stability.
 

  
   
Ultra-quiet 120mm fan with intelligent RPM control guarantees cool performance and silent operation with minimum of 18dBA during fan operation. The fanless mode operation deactivates when PSU’s loading reaches 20%.

1. My computer will trip the circuit breaker in my house, how do I prevent this?

A：

If your computer is tripping the circuit breaker that means it is drawing too much power from one outlet. Please do the following：

1. Please make sure the computer is plugged directly into the wall outlet and do not use extension socket or other multiple outlet extension cords with the computer.

2. If the use of extension socket is necessary, avoid combined usage with other higher powered household appliances such as TV, audio amplifier, etc…

3. Contact your local electrician for information on how you can upgrade your house to accommodate higher electrical draw.

2. How to Jump Start your power supply (Paper clip test)

A：Please refer to the following PDF.
