Test the bridge rectifier diodes using a multimeter in diode mode. If any diode reads a direct short (0V drop), replace the rectifier.
A small 4-pin wiring harness connects the PSU to the PS4 motherboard to manage power sequencing:
Before diving into the schematic details, it is important to understand the operating parameters and constraints of this power supply module.
Examining the PS4 ADP-160ER schematic diagram on Scribd breaks the system down into three distinct, localized circuit blocks: 1. Input EMI Filtering and Rectification Adp-160er Schematic
Elias took the schematic and folded it carefully back into his pocket.
He pulled up a blurry, hand-drawn schematic on his monitor—a digital ghost of a map shared on an old forum. Using his multimeter, he traced the 12V line back toward the heart of the PSU. The path stopped cold at . The MOSFET was a charred husk, a tiny casualty of a sudden summer lightning storm.
: The Q4 MOSFET is a frequent casualty of power surges. Test the bridge rectifier diodes using a multimeter
Always respect the separation line printed on the PCB layout. The "Hot" primary side is directly referenced to the AC grid and can cause lethal electrical shock.
When repairing an ADP-160ER without power output, focus diagnostics sequentially across the components listed in the technical schematic: Blown Blown MOSFETs and Capacitor Failure
While proprietary schematic diagrams from Sony are strictly guarded intellectual properties, reverse-engineered block diagrams and circuit tracing reveal that the ADP-160ER relies on a standard dual-stage switching mode power supply (SMPS) topology. Examining the PS4 ADP-160ER schematic diagram on Scribd
. Finding an official schematic can be difficult as Sony does not publicly release them, but technical communities have reverse-engineered diagrams to assist with common repairs. Key Technical Specifications The ADP-160ER (also interchangeable with the N16-160P1A
Comprehensive Guide to the ADP-160ER Power Supply: Schematic Analysis and Troubleshooting
A common cascading failure occurs when primary switching MOSFETs ( or equivalent primary stage transistors) short out under thermal stress. When these elements fail, they often take out local ceramic snubber capacitors ( C18 and C19 ). Check these components with an ESR meter if you hear ticking noises or notice zero output voltages. The "1-Second Shutdown" Fault
Check for shorts between the Drain and Source pins of the primary switching transistors.
The ADP-160ER is a internal power supply unit (PSU) manufactured by Sony and Delta Electronics. It is used exclusively in the PlayStation 4 (PS4) Slim hardware revision (specifically the CUH-20xx series). When a PS4 Slim fails to turn on, displays a blinking blue light, or cuts power abruptly, the root cause is frequently found within this specific PSU module.
