Do you have an interest in converting one of these, this ATX PS board has leads for +5 (RED), -5 (WHITE), +12 (YELLOW), -12 (BLUE) volts, Ground (BLACK) and switch (GREEN). Measured voltages on this particular PS (1996 P5-100 MHz Gateway) were about 5.15 and 11.75 volts. The remaining leads have been clipped off at the circuit board.Wiring coming off an industry standard circuit board will be:
ORANGE +3.3v, YELLOW +12v, BLUE -12v, RED +5v, WHITE -5v, BLACK GND, GREEN Power On if shorted to ground, GRAY Power OK, PURPLE +5v stanby, BROWN +3.3v Remote sensing
If you like convert this switching for ham radio, only 13,8 v 30 Amps.
Please read carrefully this schematic :
R 42 -for 13.8 V = 20 K
R 45 -for 13.8 V = 15 K

saya ada atx switcing bekas, untuk 5v nya 20 amp, apa bisa dimodif 13.8v 20 amp, dan apa kelemahannya untuk digunakan pada hf radio saya.
Bisa.... coba ikuti instruksi diatas. Saya gunakan bekas switching ATX 13.5volt untuk Kenwood TK80 gak ada masalah selama ini (rating power radio antara 30-40 watt normal.
masmasih kurang jelas tuh cara rombaknya tu ps tolong di perjelas lagi dong biar gampang di mengerti ato emailkan caranya ke hz_culun@yahoo.co.id terimakasih sebelumnya
