Adaptar Fuente De Pc A Ps4 Fat May 2026

| ATX Rail | PS4 Requirement | Compatible? | | :--- | :--- | :--- | | +12V (main) | 12V / 10-15A | Yes – modern ATX supplies provide 20A+ on +12V. | | +5V (standby) | 5V standby | Yes – ATX has a dedicated 5VSB line (2A typical). | | +5V (main) | 5V for logic | Yes – but PS4 uses +5V only in standby, not main operation. | | +3.3V | Not used | No connection needed. | | -12V, PG, etc. | Not used | No connection needed. |

Because the PC PSU remains external, you will need to cut a notch in the PS4’s rear plastic or run the wires through the original AC socket hole. I recommend purchasing a DC power jack panel mount and building a compact adapter box.

Never run the PS4 without the top shielding – the 12V rail carries high current and the motherboard can short against any metal.

Use multimeter on original PS4 PSU (if semi‑working) to confirm: adaptar fuente de pc a ps4 fat

If you don’t have original PSU, use this known working mapping:

PS4 connector (male on motherboard side):
[12V] [12V] [12V] [GND] [GND] [GND] [5VSB] [PS_ON] [NC] [NC]

From your ATX PSU (via a spare 24-pin extension cut in half), extract:

Solder each connection individually and cover with heatshrink. Do not rely on twisting wires – the PS4 draws up to 10A on 12V when gaming. Solder or use high-quality crimp connectors. | ATX Rail | PS4 Requirement | Compatible

Before cutting any wires, study the PS4 motherboard’s power connectors. The original internal PSU provides three main voltages through a 6-pin or 8-pin connector (depending on your exact model):

| Pin / Rail | Voltage | Typical Max Current | Role | |------------|---------|--------------------|------| | 12V (2-3 pins) | +12V | 10-13A | Main rail for disk drive, fan, and amplifier. | | 5V (1-2 pins) | +5V | 2-3A | USB ports, audio codec, HDD controller. | | 3.3V SB (1 pin) | +3.3V | ~0.5A (constant) | Standby power for ICs, power button, Wi-Fi/Bluetooth. | | Ground (3-4 pins) | 0V | - | Return path. |

Critical note: The PS4’s power-on sequence is not like a PC. The console uses the 3.3V standby rail to keep the Southbridge (SORI/Renesas chip) alive. When you press the power button, the Southbridge sends a PS_ON signal to the original PSU. On a PC PSU, we must replicate this. Use multimeter on original PS4 PSU (if semi‑working)

Before you commit to this mod, know that used original PS4 Fat power supplies cost $20-30 on eBay. A quality PC PSU costs more. So why do this? Only for the learning experience, for extreme troubleshooting, or if you literally have zero budget but have a spare PC PSU.

That said, if you succeed, you will own one of the few PS4 Fats that can run for hours without the internal PSU heating up the case – a true custom mod.
