Testing a motherboard without a CPU can be tricky, but there are some methods that can help. In this blog post, we’ll walk you through different ways to test a motherboard without a CPU. We’ll also provide some tips on how to get the most accurate results. So, if you’re looking to test your motherboard and don’t have a CPU handy, keep reading!
Unbox For Bench Testing
When you get a new motherboard, the first thing you should do is unbox it. If you’re not planning on bench testing your motherboard, then skip to “Test Short Circuit Protection”.
1. Remove Cable Ties
Once you’ve opened up your motherboard’s packaging, you’ll need to remove the cable ties.
2. Unbox Your Components
Locate your motherboard and unbox all of its components: CPU, cooler, RAM, WiFi Card (if included), etc.
3. Remove Your Motherboard from Its Box
Remove your motherboard from its box and other packaging material(s). Be sure not to touch the bottom! This will prevent damage to the pins on the bottom of your motherboard which connect it to other devices such as case connectors. If you’ve already installed a CPU or PCIe card in this shipping container, you can also skip the CPU installation steps below and head straight over to “Test Short Circuit Protection”.
Connect PSU to the Wall Socket and Motherboard
The first way to test a motherboard without a CPU is to simply plug it into the wall and see if power gets through. This method can be done with either an ATX or micro-ATX motherboard, but we’ll be using a micro-ATX board for our example. First thing you want to do is connect your motherboard to the wall power socket using a 20- or 24-pin ATX Power connector.

Make sure that all of your components are correctly seated on your board and that none of the cables are blocking any of the motherboard’s headers. Once you’ve done all this, flip your PSU’s power switch from off to on and give it a few seconds to boot up. If everything is connected properly, you should hear a series of beeps coming from your motherboard speakers.
Then there are two different and manual ways to turn on your motherboard. First, you can press and hold the reset button on your computer for a few seconds. The second way is to move your power switch from off to on.

It should be noted that if neither of these work, it could mean that there’s a problem with your PSU or something’s wrong with your motherboard.
Test Motherboard Using RAM
Another way to test a motherboard without a CPU is by using RAM. This method will only work if both slots are empty, so you’ll have to remove the RAM already installed on your motherboard. If all goes well, you should be able to start up your computer without any problems. Let’s go over how this works!
Step 1: Connect power supply to motherboard and PSU switch to “on”
The first thing you want to do is connect one end of a 24-pin ATX Power connector to the right side of your motherboard. Next, make sure that your PSU’s power switch is set to on. Once everything is connected properly, give it about five seconds for the board’s capacitors to charge up before moving on.

Step 2: Insert memory modules into DIMM slots
Once you’ve connected the power supply, it’s time to insert your RAM. Before you do anything, make sure that both of your memory modules are compatible with each other (same manufacturer and same speed). Take one module and gently press it down into the slot at a 45-degree angle. Then put pressure on the top of the stick until it clicks into place. Repeat this process for the second stick of RAM.

Step 3: Turn on PSU switch
Finally, flip your PSU’s power switch from off to on and listen for beeps coming from your motherboard’s speakers. If everything goes well, you should be able to turn on your computer without any problems.
