Standard metal case or slim black power supply — when does the smaller housing actually matter?
I’m building LED lighting into a display wall and the power supply will sit inside a fairly narrow equipment compartment. The normal silver switching supplies would fit, but only just. I noticed the slim black versions are available in both 12V and 24V. Is there any real functional reason to use the slim version, or is it mainly useful when you’re short on mounting space?

5V, 12V or 24V — which switching power supply does my LED project actually need?
I’m putting together a few LED projects and the part I keep getting stuck on is the power supply.
There are 5V, 12V and 24V versions that all look pretty similar, then a bunch of different wattages inside each voltage.
Do I decide the power supply voltage based on how much power I need, or does it have to match the voltage of the LED strip first?
I’m trying to understand the order I should choose everything in before I buy the wrong supply.

Start with the required DC voltage of the connected equipment.
A 5V LED system requires a compatible 5V power supply, a 12V system requires 12V, and a 24V system requires 24V. Voltage and wattage are separate decisions.
Once the voltage is confirmed, calculate the combined wattage/current of the connected load and select a supply with sufficient capacity.
The current LightingWill collection includes standard 5V, 12V and 24V switching supplies, while the MEANWELL UHP range expands the available output choices to 5V / 12V / 24V / 36V / 48V.

The wattage printed on the power supply is its maximum rated output, not the amount that every installation automatically uses.
Choosing the correct size starts with the total power requirement of everything connected to the supply.
Answered by LightingWill
Lighting specialist
First calculate the total wattage and current requirement of the connected LED strips or other DC equipment.
For example, LightingWill’s standard 12V series currently includes:
- 60W
- 100W
- 120W
- 150W
- 180W
- 200W
- 240W
Higher-power 12V models extend from 350W to 600W, while the upgraded 12V series reaches 720W / 60A.
Avoid selecting a supply whose rating is already below the calculated load, and do not plan an installation around continuously operating beyond its rated output.

The main advantage of the Slim Black series is its narrower enclosure for space-limited installations.
The current fanless Slim Black range is available in:
- 12V or 24V
- 36W / 60W / 100W / 120W / 150W / 200W
- AC 110–250V input
It uses a compact metal housing with passive cooling and screw-terminal connections.
The standard metal-case ranges offer many of the same basic constant-voltage functions, so enclosure style should be chosen around the installation space, required wattage and cooling arrangement rather than assuming the slim version changes the required output voltage.
