1. 2 groups of  +12V output, Each output is up to 23A,supports high-end graphic card and PC system
2. with Active Power Factor Correction (PF>0.99) and power energy efficiency is as
high as 99%.
3. Wide voltage designing, automatically adapting to 170V-264V input voltage,
ensuring to be used under  instable voltage or low voltage.
4. EU RoHS energy-efficient chips ,Standby power consumption less than 1W.
5. meet the newest standards for energy efficiency .Utilizing Two-transistor forward configuration
technology ,Effectively reduce the switch tube loss, enhance the conversion efficiency.
6.  Using server PCB materials, 2 ounce copper PCB (maintaining stability is of topn
priority ,twice material ,twice efficiency)
7. 3 groups of independent output and 2 groups of magnetic amplification designing, Enhance the output stability in the cross load voltage condition.

8.  + 12 V, and + 5 V + 3.3 V and earth wire are adopted to Independent recovery of remote voltage feedback. The PWM is more accurate and effective detection, adjust voltage stability.

9. 12cm mute cooling fan(YL:D12SM), lower noisy, longer worklife.
10. Bulk capacitor(TEAPO:450v 330μF), lower temperature, more stable 

capability, and longer worklife.
