CRJ 24-Pin ATX Power Supply Jumper Bridge Tool

I bought this to run my power supply without a PC. This jumps your PSU to start without having to plug your PSU to a motherboard. This is the second one I bought and the first one has been working great for over a month.

It works great, was able to boot up my nzxt 800 PSU without a board connection with this.

Used this to fire up the cooling system on my computer, to get the air out, without having to power up the whole computer. These are easy to make but for the price It was easier just to buy this.

I purchased two versions of this one that connected pins 4 and 5, and the other one connected pins 4 and 6... I used the one that connected pins 4 & 5... And that one worked in it supposedly is the correct configuration of this jumper unit. I don't know if the version that connects pins 4 & 6 also works as I didn't test that one. Only saw one forum post saying that it's supposed to be pins 4 & 5. But I saw another article saying that 5 and 6 are both ground, so therefore you could also connect 4 & 6. I did not verify that I can only verify that pins 4 & 5 work with the MSI x670e Carbon Wi-Fi Motherboard. Can you imagine if there was a universal source for this and if this was exactly that standardized, I could only imagine

What's to say it worked as should was perfect for cycling on my pc to change water cooling fluid

Simple jumper to get a PSU going for testing. Cheap and fits perfectly for a 24 pin.

You buy one of these when you want to test a PC power supply and turn it on without a motherboard. All it does is shorting (maybe with a resistor) 2 pins. This works without any problem. I would have given more stars if the short was "internal" and not external like on the photo and ready to be pulled off by mistake. Also DO CHECK if your new power supply comes with one already. Mine did, I just didn't check ;-) In case that helps someone, if you have an AsRock motherboard that does not power up the power supply, it's likely not the power supply, but the coin cell battery on the motherboard that is dead. Fancy server motherboards apparently are not happy with dead cell batteries...

Simple solutions are the best solutions. I am using this to power multiple Corsair, Seasonic, and be quiet! PSU's for various use cases ranging from powering a fan stack exhausting dust generated by my CNC and laser-cutter to fans used in a custom-built Mac Mini mini-rack. Typical exhaust fans are extremely loud, so instead of standard options, I opted to create a fan stack using Noctua and be quiet 120-140mm fans. Using a SATA-powered PWM hub, this connector allows me to keep the hub online and the fans running at full speed during operation of the CNC and laser-cutter. For the custom-built Mac Mini mini-rack, this allows me to run an SFX PSU within the chassis of the rack and draw intake to the base of the Mac Mini, driving exhaust through the backplate at a faster rate.
