When it comes to building a DIY claw machine, the power supply is one of those parts that people tend to overlook — but it really shouldn't be. A lot of countries run on 110V power, which means the internal components of the power supply need to meet higher quality standards to handle it properly. On top of that, modern claw machines have a lot more LED strips than older models did, so you need a power supply that can actually keep up with the extra load. If the power supply isn't up to the job, it can cause the capacitors and resistors inside to fail — or worse, damage your main control board. That's why we use high-performance power supplies that deliver reliable, consistent power output.
The power supplies we use support a wide voltage range of 100V to 240V and come with a DIP switch, so we can easily adjust the voltage setting to match whatever market your machine is heading to.
The power supplies for the claw machines currently on the market support a wide voltage range of 100V to 240V and feature a DIP switch; we typically adjust the voltage setting to meet the specific requirements of the customer's market.
Why the Power Supply Matters More Than You Think
A claw machine is not a simple device. It contains multiple components that all draw power simultaneously:
- Main control board
- Motor and movement system
- LED light strips (often 2–4 meters or more)
- Speaker and display board
- Coin acceptor or bill acceptor
- Joystick and buttons
When all of these components run at the same time, the power supply must deliver stable, sufficient voltage and current. If it can't, the consequences can be serious.
What Happens When the Power Supply Is Underpowered?
Insufficient power capacity is one of the most common causes of claw machine failures. Here's what can happen:
- Capacitor and resistor failure — The power supply's own internal components can overheat and fail when pushed beyond their rated capacity.
- Mainboard damage — Voltage drops or surges from an overloaded power supply can fry the main control board, which is expensive to replace.
- LED flickering or dimming — When the power supply can't keep up, LED strips will flicker or go dark, especially when the claw is moving.
- Unstable claw operation — The claw may drop unexpectedly, move erratically, or fail to return to its home position.
- Frequent restarts — The machine may reset or shut down randomly during gameplay.
Why Modern Claw Machines Need More Power
Older claw machine models had minimal lighting and simpler electronics. Modern DIY claw machine kits are significantly more power-hungry:
- More LED strips — Modern kits often include 2–4 meters of RGB LED strips, which can draw 5–10 amps alone.
- Advanced mainboards — Newer mainboards with LCD displays, voice announcements, and wireless connectivity draw more current.
- Larger motors — Bigger gantries (71cm, 96cm) require more powerful motors, increasing overall power demand.
A power supply that worked for an older model may simply not be enough for a modern kit.
How to Choose the Right Power Supply
Here are the key factors to consider:
1. Voltage Range
Our power supplies support a universal voltage range of 100V–240V, making them compatible with power grids worldwide. This is essential if you're selling or shipping claw machines internationally.
2. Power Output (Wattage)
The right wattage depends on the total number of components in your kit, not the size of the gantry. A kit with more LED strips, a larger display, or additional accessories will draw more power regardless of gantry length
