| 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. |
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. Adapting a PC power supply to a PS4 Fat is not a beginner project. It requires understanding ATX specifications, standby voltage regulation, and transistor logic. But for the dedicated hardware hacker, it’s a rewarding way to resurrect a dead console without buying proprietary parts. adaptar fuente de pc a ps4 fat
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. | Pin / Rail | Voltage | Typical
If you follow this guide carefully, double-check every voltage, and prioritize safety, you can give your old PS4 Fat a new life powered by a reliable, cool-running desktop PSU – and maybe even an external on/off switch for the whole rig. | | Ground (3-4 pins) | 0V | - | Return path
– the 12V rail carries high current and the motherboard can short against any metal. A Better Alternative: Buying a Replacement PSU 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.
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.
Introduction: The PS4 Fat’s Silent Killer If you own an original PlayStation 4 (the "Fat" or "Phat" model, CUH-10xxA to CUH-12xxA), you have likely encountered one of its most infamous failures: the power supply. The internal ADP-240AR, APS-250, or LITE-ON power supplies are known to die due to overheating, capacitor aging, or failed MOSFETs. When they do, Sony’s official solution is a full board replacement – often costing more than a used console.
