![]() Some motherboards and some sata controllers have staggered spinup, where they turn on each drive in sequence, waiting a few seconds between each drive. You have 62A on 12v, so if that's the case your 24 drives would peak at 48A of current when you turn on the PC. the 5v current will not be significantly higher. So, reserve 1A for each SSD.Įdit: Yeah, the motor on mechanical drives will consume more current when it starts up, up to 2A or so on 12v. Reserving 0.75A of current on 5V for each mechanical drive, in theory you should be able to add up to 18 / 0.75 = 24 mechanical drives.Ī SSD consumes less power, around 1w when idle and reading files, but during long periods of writing some SSDs can consume up to 5-8 watts, and all this is from 5v - pretty much all SATA SSDs are 5v only. So assuming the motherboard and other things in your computer (usb devices, chipset, onboard sound, optical drive, whatever) needs around 4A of current on 5v (20w), this means you have at most 18 A of current on 5v. Your first limitation will be the maximum output current the power supply can provide on 5v, which in your case is : It will take up to 0.5-0.8A from 5v (~4w) and up to around 0.5A on 12v (6w) Because, in this method, you have to buy SATA splitter cables.A mechanical drive will consume around 8-10 watts, from 5v and 12v. Method 3: Using SATA Splitters Cables (Best Method)Īs we noticed, both the methods explained above have some downsides, which is why this 3rd method will be considered best for you. Moreover, experts don’t recommend using these adapters because of losing all of their data. However, fire may catch outside the PC case in a worst-case scenario. These Molex to SATA adapters don’t have proper shielding therefore, the electrical arc jumps from one voltage to another line, which can cause severe damage to the Power Supply, adapter, and other system components. These adapters have 5.5v red wire, 12v yellow wire, and ground connection black wires. If you don’t have the SATA power connector left, you can buy this type of Molex to SATA adapter, but there are some downsides to using this type of adapter. You have to plug the four male Molex sides into the female Molex connector that comes with your Power supply, and on the other end, you can install drives according to your need. ![]() The 2nd method of adding a SATA power cable is using the Molex to SATA power connector these cables are usually very short in length and cost-effective. ![]() Moreover, it could have toasted components or catch fire in worst-case scenarios. Many experts do not recommend adding SATA power cables in this way because buying an incompatible or wrong cable may end up with a 12v cable where there is a need for 3v. In that case, buying the cable from the PSU maker or custom cable maker is recommended to ensure compatibility with your specific PSU model. Suppose you have a modular or semi-modular PSU. Still, you must buy the cables specifically compatible with your Power Supply. Now, you can add an extra SATA power cable if you have open SATA power inputs left in the Power Supply. Some spots will be SATA, while some will be Molex. The image shows the peripheral & SATA connector: These connectors usually come with enough cables to plug something into each spot.
