PSU Inside

If you open your PSU, your warranty is gone. We still had to peek inside it.



There are two trimmers located inside the case. Using these trimmers you can tweak your output voltages. VR1 directly controls the 12V line. I could reach values between 11.64V and 12.20V. What VR2 controls is unknown. I saw no changes to the 3.3V, 5V or 12V line when turning it.

Test Equipment

  • The PSU is connected to an APC SmartUPS which supplies clean 220V input.
  • AC current is measured using a Peaktech 4010 desktop RS232 multimeter with 0.02A accuracy.
  • To measure DC output voltages of the PSU we use a 20-bit data acquisition system calibrated to 10uV accuracy.
  • Power Factor is measured using a generic Power Efficiency Meter.
  • Measurements for Ripple Voltage were obtained using a 30 MHz HAMEG Analog/Digital Oscilloscope.
