Perfect solution for those extra unused SATA connections from your PSU
Like many, I have a modern PSU with over a dozen SATA power connections. Although my power supply is modular, I like to keep my power cables attached for when I add another SATA device. These are the perfect solution to dust and debris getting into your SATA power connections. Now I can leave my SATA cables attached to the back of my PSU without the worry of them getting filled with dust from my PC fans. They slip right on, and are perfectly keyed (they only go on one way) and fit perfectly on your SATA power cables. With dust-covers always buy many more than you think you'll need. These are not easily purchased anywhere. The price at Bestbyte is fantastic.
