Scythe SPTRPN-500 80plus Platinum Certified Semi-Fanless Active PFC ATX 12V Power Supply


scythe 80plus platinum 500w

Scythe sptrpn-500 500-Watt Naked Platinum ATX/EPS 12V
80PLUS Platinum Certified Power Supply

Fanless when system load is under 300-WATT*

That means this power supply is so efficient and it generates so little heat that under normal operation, the cooling fan does not need to turn on -- making it a 0db silent Power Supply.

* Between 250W to 300W, depending on ambient temperature and chassis internal airflow condition


UL certified safety
power cord included

Low Noise

80PLUS Platinum certification Silent ATX power supply specification

  • 80PLUS Platinum certified, higher efficiency than gold, silver, or bronze
  • Single +12V output @ 41.5A (continuous)
  • High quality Japan-made 105℃ capacitors used throughout
  • Fanless mode implementation:
Power supply is running on fanless state that does not rotate the fan at the time of low load. Fan will begin to rotate at a load of about 250 ~ 300W.
  • Fan delay off feature: When fan is required to turn on due to large system load, it may remain to rotate to continue to cool down the PSU a few seconds after the system is shut down.
