Fat — Adaptar Fuente De Pc A Ps4

Solder your custom harness directly to the motherboard’s power input pads (or to the original connector if you saved it). Re-check polarity twice. Then connect the PS_ON control transistor circuit as described.

Double-check: The PS4 motherboard must NEVER receive 12V on the standby pin. That will fry the Southbridge instantly.

A regular ATX PSU requires a PS_ON# signal (green wire on the 24-pin) pulled to ground (black) to turn on the main rails (12V, 5V, 3.3V). But for the PS4, we need 3.3V standby power always present – that is pin 9 on the ATX 24-pin (purple wire, +5VSB? Wait – correction: ATX supplies +5V standby, not 3.3V!). Problem: PS4 needs 3.3V standby, but PC PSUs provide +5VSB.

Solution: Use a voltage regulator to drop 5VSB to 3.3V. Or, simpler: Use a small 3.3V linear regulator (e.g., AMS1117-3.3) fed from 5VSB. Some PS4 models (rarely) accept 5V standby if their onboard regulator handles it – but do not risk it. True 3.3V is required. adaptar fuente de pc a ps4 fat

So:

Also, the PS_ON signal: On a PC PSU, you must connect the green wire to a ground to start the PSU. For the PS4 to control power, we will instead wire the PS4’s PS_ON signal (from motherboard) to the green wire on the PSU via a small transistor inverter, because PS4’s PS_ON is active-high (3.3V to power on), while PC PSU wants active-low (ground to turn on).

Simpler hack for advanced users: Use a small relay or an NPN transistor (2N3904). Connect base to PS4’s PS_ON via a 10k resistor. Emitter to ground. Collector to ATX green wire. Also pull green wire up to 5VSB via a 1k resistor. When PS4 sends 3.3V, transistor turns on, pulls green low → PSU starts. Solder your custom harness directly to the motherboard’s

El "Trick" de encendido (Standby):

| Problem | Likely Cause | Fix | |---------|--------------|-----| | Red light present, no power-on | PS_ON signal not reaching green wire | Test with multimeter: When pressing power, does PS4 output 3.3V on its PS_ON? If yes, check transistor. | | PSU shuts down after 2 seconds | No load or short | Add a dummy load (HDD or fan). Check for short between 12V and GND. | | 3.3VSB drops when power pressed | Regulator can’t supply enough current | Upgrade to a 1A LDO regulator or use a DC-DC buck converter (5V to 3.3V). | | USB ports don’t work | 5V rail missing | Confirm red wires are soldered correctly. | | Disc drive doesn’t eject | 12V not present | Check yellow wires. |
