The Signs & Symptoms of a Defective PS4 Power Supply

PS4 Power SupplyPS4 consoles that have defective power supplies don’t receive enough power that can cause subtle symptoms like graphical downgrades to obvious extreme symptoms like being unable to turn on.

If a PS4 console isn’t receiving enough power, the cause likely stems from the device’s power supply being unable to provide enough power to the console, or the power supply is failing. The power connection is probably not at fault, but sometimes the problem stems from the PS4 power cord itself, so you have to check out this.

If you’re running a lot of electrical devices on a single circuit the breakers will usually trip above 1,800 watts — game consoles usually run between 200 and 400 watts — and cut power to the entire circuit.

Graphics Downgrade

Other than the CPU, the PS4’s graphics card is the most power-hungry component in the system. The GPU is a likely target to show the earliest symptoms of being underpowered. When the PS4 power supply is defective, the graphics card will be underpowered and it will drop the performance levels and display graphics at a lower quality.

The graphics downgrade will usually trigger if you run a graphics-heavy game or application that pushes the card to its limits. Graphics settings drops are usually accompanied with an error message and often start when you add new hardware to the system or replace the old hard drive with a more power-demanding one. This is one point why an SSD is a great option when it comes to power consumption. Read more on the best PS4 internal hard drive replacement.

Display Irregularities

If the PS4 monitor is flashing or displaying dots and lines when it shouldn’t be, the PS4 may not be getting enough power from the power supply unit, or the power supply is defective and causing power fluctuation.

The insufficient power can cause the CPU and graphics card to render screen displays inconsistently. Additionally, the graphics card may turn off the monitor if there’s not enough power to render on-screen graphics. This is particularly common in multi-monitor setups.

Unstable System

Random app/game crashes, system freezes and the Blue Light of Death are all symptoms of a PS4 that’s not getting enough power.

Like with graphical degrades, system instability symptoms often follow adding new hardware or upgrading existing components. System instability issues from insufficient power can be reversed by upgrading the power supply or reducing the draw on the existing one by disconnecting unnecessary components.

PS4 System instability can also cause driver errors and disable individual system devices.

Additionally, if the PS4 isn’t getting enough power the PSU may just give up and shut down the entire system. The forced shutdown is similar to the blue light of death, but the power is so insufficient that the system immediately shuts down and is unable to even display an error message/signal.

System Won’t Power On

A PS4 console that has a severely inadequate power source won’t turn on at all. In a better-case scenario, the PS4 may power on and display a splash screen before the power gets cut. However, the system refusing to power on is a symptom of several other hardware problems like a broken PSU. If the system won’t power on following adding a new component or upgrading an old part, try swapping the old one back in and seeing if the PS4 powers on. If the system still powers on, either the new component is defective or the power supply can’t handle it.

Damaged Components

A defective PS4 power supply can cause damage to several components inside the console, including the hard drive and CPU.

As for the PS4 hard drive, the sudden and unexpected power shocks caused by a defective power supply will cause scratches on the surface of the HDD platter, that will end up eventually with the damage of the hard drive. Even if you’re using an SSD, this unstable power environment will shorten the lifespan of the SSD.

A defective PS4 power supply can also corrupt the data stored on the PS4 HDD. This will lead to PS4 freezing, PS4 database corruption and PS4 suddenly turns off.


The time you notice your PS4 is behaving weirdly and not functioning as it should be, the power supply must be one of the main suspects.

Failing to defect a defective PS4 power supply may be dangerous in the long term and cause serious damage to the innards of the PS4.

Try all possible solutions to fix PS4 errors, if none worked with you, it’s time to diagnose the PS4 power supply for potential defects.

    Last night I played PS4 and I was still safe… today I tried to play it and I turned it on… But the PS doesn’t want to turn on anymore and there’s no sign of anything… Please enlighten me.

      I apologize for any confusion caused. If your PlayStation 4 is not turning on at all and showing no signs of power, there are a few things you can try to troubleshoot the issue:

      1. Power source: Ensure that the power cable is securely connected to both the PS4 and the electrical outlet. Check if the outlet is working by plugging in another device.
      2. Power cable and adapter: If possible, try using a different power cable and adapter to eliminate the possibility of a faulty power supply.
      3. Power cycle: Disconnect the power cable from the PS4 and leave it unplugged for about 10-15 minutes. This will allow the system to reset. Afterward, plug the power cable back in and try turning on the console.
      4. Check for physical damage: Inspect the power cable and the PS4 itself for any visible signs of damage or loose connections. If you notice any issues, it may require professional repair.
      5. Test in a different outlet: Plug the PS4 into a different electrical outlet to see if it makes any difference. Sometimes, a specific outlet may be causing the problem.
      6. Contact PlayStation support: If none of the above steps resolve the issue and your PS4 still doesn’t turn on, it’s recommended to reach out to PlayStation support for further assistance. They will be able to guide you through additional troubleshooting steps or advise on repair options.

      It’s worth noting that without physical access to the console, I can only provide general suggestions. For more specific and accurate guidance, it’s best to consult with PlayStation support or seek professional repair services.

    My PS4 model CUH-1115A recently stopped turning on. When I touched the power button, I got one beep with no lights and then nothing. After a few minutes, I tried unplugging, plugging in, and touching the power with the same results.

    Hey! So I recently acquired a launch PS4. My friend said that after cleaning it out, the power button stopped working and that whenever he tried to update the console via OTA, it would error out, and he couldn’t enter safe mode.

    Hey! I recently acquired a launch PS4. After cleaning it out, my friend said that the power button was no longer functional. He also claimed that whenever he tried to update the console via OTA, an error message appeared and that he was unable to enter safe mode.

    He claimed that he could only switch it on using a hiss controller. It was around two weeks ago. I now own the console, however nothing happens when I connect it into the wall.

      Performance drops or the PS4 not turning on at all can be caused by power supply issues. A shortfall in the internal power supply unit brought on by the entry of dust, filth, and even insects are typical PS4 power supply issues.
