The PlayStation 3 is a beast of a machine, but it’s also kind of a dinosaur. Honestly, if you’ve just pulled one out of a dusty attic or snagged a "backward compatible" CECHA01 model from eBay, you might be staring at that sleek, piano-black finish and wondering where the actual buttons are. It’s not like a PS5 or even the PS4. It’s got these weird, touch-sensitive spots that don't click, or maybe you have the later models with actual physical buttons that feel totally different.
Learning how to turn on a PS3 seems like it should be dead simple. It’s a power button, right? Well, sort of. Depending on whether you have the OG Fat, the Slim, or the Super Slim, the process changes enough to be annoying. Plus, these consoles are getting old. Capacitors fail. Power supplies give up the ghost. Sometimes the "on" button doesn't even mean the console is actually starting up.
The Different Ways to Wake Up the Beast
First off, let’s talk about the most common way to get things moving. If you have a DualShock 3 controller and it’s already synced to the console, you don't even need to touch the machine. Just hold down the circular PlayStation button in the center. The four LEDs on the top of the controller will blink, and if the console is plugged in and the main power switch (on the back of older models) is flipped to "on," the system will beep and chime to life.
It’s the easiest way. No standing up required.
But what if the controller is dead or unsynced? That’s where things get specific to your hardware version.

The Original "Fat" PS3 (The 2006-2009 Era)
These are the heavy ones. If yours has four USB ports on the front, you’ve got a gold mine—that’s the version that plays PS2 discs. To turn this one on, you have to look at the back first. There is a physical I/O toggle switch near the power cable. Flip that to "I." A tiny red light will appear on the front panel.
Now, look at the front. See that "I/O" symbol? That isn't a button you press down. It’s a capacitive touch sensor. Just tap it with your finger. You’ll hear a beep, the light turns green, and the fans start spinning like a jet engine. If it doesn't beep, try using a different finger; sometimes skin oils or dust make those sensors finicky.
The PS3 Slim (The 2009-2012 Workhorse)
Sony realized people hated the touch sensors (and the fingerprints they left behind), so the Slim went back to basics. On the left side of the disc slot, there are two big, physical buttons. The one on the left is Eject; the one on the right is Power. Give it a firm press. It clicks. It’s satisfying. No rear power switch on this one—just plug it in and go.
The Super Slim (The 2012-2017 Budget King)
The last iteration of the PS3 is the one with the sliding top door. This one is weird. The power button is a skinny rectangular strip on the far left of the front face. It’s actually part of the plastic trim. Push it in, and the LED next to it will jump from red to green.

When the Power Button Does Nothing: Troubleshooting 101
Sometimes you follow the steps for how to turn on a PS3 and... nothing happens. Or worse, you get the dreaded "Yellow Light of Death" (YLOD). This is where things get real. If you press power and the light flashes yellow for a second before blinking red, your console has a hardware failure—usually the NEC/TOKIN capacitors or the RSX chip solder joints failing due to years of heat cycles.
Before you panic and throw it in the trash, check the simple stuff:
- The Power Cord: The Fat PS3 uses a thick "kettle" lead (C13), while the Slims use a figure-eight (C7) cable. Make sure it's shoved all the way in. They can wiggle loose.
- The "No Signal" Trap: Is the console on (green light) but the screen is black? This happens if you last used the PS3 on a different TV or with AV cables instead of HDMI.
- The Video Reset Trick: This is a lifesaver. With the console in standby (red light), press and hold the power button. You’ll hear one beep when it starts. Keep holding. About five seconds later, you’ll hear a second beep. Let go. This forces the PS3 to reset its video output settings to the lowest resolution so you can actually see the menu and reconfigure your HDMI settings.
Why Does It Matter How You Turn It On?
You might think, "Who cares? Just hit the button." But the PS3 is a sensitive piece of tech. If you’re turning it on after a long time, the internal clock battery (a CR2032 hidden deep inside) is likely dead. This can cause issues with digital licenses and syncing with the PlayStation Network.
Also, if you're using the power button to turn it off, please don't just yank the cord. The PS3 uses a file system that absolutely hates being interrupted. Always shut down through the "Turn Off System" menu option or by holding the power button until it beeps and shuts down gracefully. If you don't, you'll be greeted with a "The file system on the system storage is corrupted and will be restored" progress bar the next time you boot up. It takes forever. It’s a pain.

Taking the Next Steps with Your PS3
Now that you've mastered how to turn on a PS3, don't just let it sit there. These consoles are currently in a "sweet spot" for collectors and retro gamers. If you have a Fat model, consider opening it up and replacing the thermal paste; the original factory paste is likely as dry as a cracker by now, and fresh paste will keep your console from overheating and dying.
If you're looking to actually play, remember that the PS3 Store is still technically functional, though you have to add funds to your wallet via a PS4, PS5, or the web first. You can't just buy stuff with a credit card directly on the PS3 anymore.
Actionable Next Steps:
- Check your firmware: Go to Settings > System Settings > System Information to ensure you're on version 4.90 or 4.91 (the latest updates).
- Sync your controller: If the wireless isn't working, use a standard Mini-USB cable (not Micro-USB!) to hardwire the controller to the front port for a minute to re-pair it.
- Clean the vents: Use a can of compressed air to blow out the back vents while the console is off to prevent the fan from working harder than it needs to.
- Test the disc drive: Insert a Blu-ray or DVD to make sure the laser is still reading; these are often the first components to fail after years of sitting idle.
