Hard drive power converter

HDDs are comprised of several parts and fall under the category of electromechanical devices as they have moving parts. These include the disks where the data is stored, the motor that spins the disks, and the armature and head that reads the disk, it is a similar concept mechanically to a record player, only a lot smaller, faster, and more precise.

The HDD needs power so that the individual components can operate enabling the drive to store data. The data is stored via a magnetic charge on a ferromagnetic film that coats the disks. SSDs work slightly differently, they have no moving parts and instead store the data in the form of electrical charges.

These charges can represent a 1 or 0 in the same way as magnetic polarization can which is used to store data in binary. SSDs need power to not only write the charges but also to read them and transmit the data to the computer.

They run on a 5v supply or 12 supply which is stepped down internally in the drive to meet the requirements of the individual drive. HDDs come in various sizes, most commonly 3. This is where the power requirements deviate. The PSU then delivers power to the individual components. The drive is then also connected via a data interface cable to the motherboard. This is usually a SATA cable. Has your mind been juggling between choices when it comes to buying External Hard Drive With Power Supply in general, specifically regarding which model to choose?

Then our AI ranked them on their quality-to-price ratio using industry-standard criteria that let us pick the best External Hard Drive With Power Supply currently on the market! We consider several criteria before assembling a list. Some of the criteria are discussed below- Brand Value: What happens when you go for a not-so-reputable brand just because the price seems cheap? Well, the chance of getting a short-lasting product goes higher.

Top External Hard Drive With Power Supply brands try to offer some unique features that make them stand out in the crowd. Specifications: Numbers always help you measure the quality of a product in a quantitative way.

We try to find products of higher specifications, but with the right balance. As mentioned in the intro, the model does not have a mount for the LED status light. Feel free to modify and add an LED mount where you want. Download the files from Thingiverse - Power Supply Enclosure. My printer settings were layer height of 0. Took about 13 hours for the bottom and about 2 or so for the top.

I also found that I have to back off the tap more often than I do for metal. The plastic tends to buildup on the tap and makes cutting new threads harder or worse binds the tap and you strip your previously cut threads. Use panel mount jacks that have a flat side on its body. The enclosure is made to fit these panel mount DC jacks. The flat side prevent the jack from spinning allowing you to tighten the holding nut easier.

First tin the DC jack leads out of the enclosure. You could do it in the enclosure, but feels like would be a bit harder due to the lack of space once in the enclosure.

My external hard drives use center positive DC power supply plugs. Make sure to wire up your jacks correctly for your hard drives. Place the jacks in the enclosure and make sure you line up the leads for polarity. The leads are uneven in length. Either keep all long leads closer to bottom or vice versa. This will make wiring much easier as you won't have crisscross wiring of the jacks.

Mount the perfboarded fan controller on the 4 stand-offs nearest the DC jacks. Mount the DC buck regulator on the 2 stand-offs to the left of the perfboard's stand-offs. Screw the regulator to the stand-offs with the output facing the perfboard. Do not connect the power from the regulator to the perfboard yet. To use the faceplate you first need to remove the LCD circuit board.

The circuit board prevents the faceplate's holding tab from moving. The circuit board is held in place by the short side of the faceplate. Push out the short side to release the circuit board. Make take a bit of force but the faceplate is pretty tough.

Take note of the orientation of the LCD cover to the circuit board as the cover will fall out. Insert the faceplate into the right square hole fronting the DC buck regulator stand-offs.

The faceplate should snap into place. Insert the LCD cover and circuit board back into the faceplate. Ensure that you place the LCD cover correctly or else the labels will be incorrect. Keep the split side short so that the wiring in the enclosure will be a bit more tidy.

Use shrink tubing to insulate the Y connections. Use a ring terminal to crimp all the ends together. I found slipping shrink tubing around all the wires keeps the wires packed together.

This makes twisting the bare wires together for crimping on the ring terminal much easier. Crimp a ring terminal onto the two black wires. Create a Y split on the end of the of the blue wire that will connect to the DC jacks. Before soldering the Y end, attach another wire that faces opposite of the Y that will connect to the negative input of the DC regulator. Solder the loose power wires ends in place DC buck regulator and DC jacks positive and negative terminals.

Make sure the DC buck regulator is not connected the fan controller perfboard as the regulator may not be correctly set. Connect the positive and negative ring terminals made in the previous step to a 12V power supply. Mount the 12V PSU onto the two stand-off left. My PSU base was a little bent from shipping or prolly bad manufacturing. I super glued a thin piece of foam on the square risers in the enclosure to prevent the PSU from wobbling.

Test fit the power socket into the enclosure. This gives you an idea of how short you can make the wires to connect the socket to the power supply. Follow the wiring of your fused socket. Use colored wires that match your countries standard.

The colors used in the pictures are black-live, white-neutral, and green-ground. Use insulated female disconnects on the power socket. If you solder, make sure you shrink wrap the soldered terminals. I prefer the terminals as they are easier to fix and remove should you need to repair something. Use ring terminals to connect to the 12V PSU. Try to keep the wires short but not too short because you will need some wiggle room to move wires off to the side to make room for the ring terminals to the PSU.

When the wires are connected. Make sure a 10A fuse is in the power socket fuse holder. Do a quick test by connecting the power cord to the power socket.

Fix the power socket into place with screws, washers, lock washers and a nuts. Use hot glue on the screw from the inside of the enclosure for insulation. You will probably have to goop the hot glue onto a thin piece of cardboard to apply the glue since space is tight.

Use tie wraps to fix the temperature sensor in place. I placed the sensor between what looked to be the regulators on the PSU. Make sure the cable is fixed down so that it does not interfere with the fan. Use the tie wraps to fix the LED in place. Test the controller again by plugging the power cord and turning on the power supply. Use a hair dryer and gently heat up the temperature sensor.

The fan should eventually turn on. If it doesn't, check your wiring. Make sure to unplug the power before rechecking. If everything tests out okay, remove turn off the power supply and remove the power cord.
