![]() This method of connecting the case fan is convenient and safer to use. These are the best and most reliable ways to connect your case fans with PSU. One is through the controller, and the second is through a Molex power cable to a 4-pin fan converter. There are two ways to connect case fans to your PSU. Additionally, if you want complete control over fan speed and colors in RGB fans, it is a great option. Connecting to the motherboard is a safer and more reliable option. It’s a more compatible option than the power supply. This method is convenient because it doesn’t require any additional hardware.Īlways try to connect the case fans with your motherboard. The most common way is to connect the fan’s power cable directly to the motherboard’s header. You can connect the case fan with both either the motherboard or power supply. However, not all power supplies have this feature, so it’s something to consider when choosing a PSU for your custom PC.ĭo Case Fans Connect To A Motherboard or Power Supply? It is the most expensive option, but it’s also convenient. Some high-end power supplies come with built-in fan controllers. But if your motherboard lacks a fan header, the power supply is the best option. A motherboard with a fan header can be directly connected to a case fan. They are, however, cheap and it may take a month or to to get one here based on shipping estimates.If you are confused about do case fans connect to a motherboard or power supply? Then the answer is both options are valid to use when connecting a case fan. The only ones I have found are made in China and are of dubious reputation. Another solution is to buy one of the smaller, non-powered USB "splitters" to break out the USB header on the mother board to two USB 2.0 ports. The latter uses SATA power and provides additional USB headers. My solutions are either to buy a molex to SATA adapter of which I could only find one example to power the NZXT hub or to replace the Corsair Lighting hub with the CorsairCommander Pro. None of the PCIe cards I saw provided internal headers and some required molex power. I then need some way to provide more USB 2.0 headers. So, in order to use the Corsair Lighting Pro, I had to scavage one of the 9 pin USB headers which means disconnecting something from the front panel. So, if I want the use of that, I'll need to provide a USB internal header to which to attach it, or a 9 pin internal header to which to move the front panel USB 2.0 port connector. I assume the four pin is the card reader. The only front panel connections not accounted for so far are the audio connections and the card reader. The second USB 2.0 connector had a four pin white connector doing to the front panel. It is a nine 9 pin connector that I assume provides two USB 2.0 ports.ģ. One feeds the two USB 2.0 ports on the front panel. There are two USB 2.0 connectors on the mother board. So, if I decide to use the NZXT HUB I would need to get one of those.Ģ. I did find an adaptor, molex to SATA that would work to correct that issue. There definitely is no molex connector from the power supply. It seems molex connectors are a thing of the past although most commercially available power supplies, both modular and semi modular and non-modular, all have at least one.ġ. ![]() Much wasted time, some wasted money all due to an assumption on my part. So, I can connect it to the mother board and then connect the front USB 2.0 connectors to it. The Commander Pro is more than I need as I don't have any fans to control, however, is uses SATA power and has two USB 2.0 connectors. However, in the end decided to bag that solution and just upgrade from the LIghting Node Pro to the Commander Pro. I searched and found, finally, molex to SATA power adapter. There are a number of SATA power connections, but no molex. However, from what I can determine the power supply in the 870-244 does not. I assumed all power supplies would have at least one. However, the HUB requires a molex power connection. I then started looking for ways to regain the front connectors and hit on the NZXT USB HUB. I had to remove the front USB 2.0 connector to accomodate. EXCEPT, there is only one USB 2.0 header on the mother board and that is what the Lighting Pro needs to connect. However, I bought a Corsair Lighting Pro and it all worked out just fine. ![]() I decided to install internal RGB lighting in my Omen 870-244. I've been following a rather torturous route here.
