Ahhh the hassle of old hard drives. If you ever need to get the data off an old drive—or just want to check the drive and maybe erase it before disposal—you could always crack open your PC and mount the drive inside. There are much better solutions around these days. The trouble with an enclosure is that it takes almost as much time to mount the drive in an enclosure as it does to mount the drive in your PC. The beauty of a dock like this is that you can leave it connected to your PC and just plug in an old hard drive whenever you need access. Some docks even let you connect two hard drives at once. If you routinely work with old drives, a dock is well worth the price.
New Motherboard & Power Supply Keep Rebooting Every Few Seconds
Ask Question Step 3: I decided to not cut up my PSU cables as i may need the computer it came from at some point, you will need to find the pins shown in the pic, they are on the connector that was originally on your motherboard, the cables should be green and black, any black ground connector will do the trick. Now a quick check, turn on your PSU and if the fan spins you’re all set for the next step.
Add Tip Step 4: Wiring Your Amp So you have your amp ready?
The Y cable allows one power supply to be hooked up to multiple tube lights at the same time. The cable has mm male and female plugs. Use this harness to connect the LED Power Supply to flexible led light part number or to connect other 12 VDC products to the LED power supply. The harness length is 18 Inches.
Years ago, before I had any idea of how a computer works, my brother started to play World of Warcraft. I would always enjoy watching my brother play Jonathan Kwan February 11, Images re-encoded on April 23, You may or may not have heard of this before, you might have not even thought of this before, or if you are just wondering how it’s done, we’ll present you with the so-called “Paperclip Trick” today — a commonly known trick between computer enthusiasts and modders.
After reading the previous paragraph, you are probably still wondering, “Yeah yeah, whatever. Just tell me what the heck are you talking about!? This is too inconvenient for people who wants to use their power supply to test out certain things, and to get around this, we’ll have to fool the power supply into thinking that there is a motherboard there and the switch on your case is pressed.
If you have an extra power supply dedicated for testing components, this tutorial will also be very useful. So from now on, after this simple trick, you can now turn on your power supply with the switch at the back of it. And all you need is a paperclip and around two minutes or less of your precious time.
You won’t need much computer knowledge or something — just follow the simple instructions and use some common sense.
Monitor is in power save mode-won’t boot up
Mar 27, , I ran through the checklist and couldnt find anything that I did incorrectly. I ordered it from Amazon, but who knows how long they have had it. Is there any way to update it without buying a new CPU? Not sure if that gives any more information. TheDraac Mar 28, , 1:
You power up second PSU first, then turn up PC. When turning off, turn PC off first, then second PSU. That said, add2psu looks like a nice hassle free option for less than $
If you don’t see something that looks like that, you may want to get one. Nah, I don’t have one.. I’ll probably have to go downtown and pick one up today. I am reading this, and I hear you say that you do not want to try to start the board by shorting across the 2 power pins. However, you state that you are certain the power supply is not bad, because you have tested each of the power supply leads with a tester.
Your statements lead me to believe that your assessment of your PSU may not be conclusive. A motherboard speaker, so you can listen to beep codes, is a must for troubleshooting these things. I followed this tutorial http: Checked the motherboard and CPU pins.
Convert an ATX Power Supply Into a Regular DC Power Supply!
September 29, 8: I have an old and used laptop. An HP Elitebook p. Around an year ago, the charger that I had received with it fried. Since it was an old system, I couldn’t find any new or genuine chargers so I had to buy a cheap knockoff charger.
Orion Dynamo Pro Wh AC/DC/USB Lithium Power Supply With its huge watt-hour capacity, the Dynamo Pro Lithium Power Supply will keep your astronomy gear powered up all night long. Features three USB outputs, three w DC outputs, and one w AC output.
People want power in a compact form factor. They want more usable desktop and floor space. With the right components, you no longer need a big PC to handle some hardcore modern gaming. They’re fun, compact, and usually look great when completed. If you want a build that’s easy to move and can still kick ass, a mini-ITX rig might be for you. That said, mini-ITX cases are often much tighter in terms of clearances and room for error.
You’ll have to spend more time planning your build, and making sure you buy components that will actually fit inside the case. Mini-ITX cases don’t offer a lot of place to stash your wiring mess, so make sure to cut down on cabling as much as you can. If you can use an M. When choosing a PSU, go for semi- or fully-modular so you can keep the excess out of the case.
While these two considerations can keep any rig looking clean, they become even more important when physical space is at a premium. On a technical note, all case manufacturers define a mini-ITX case as having a maximum of 2 rear slots.
Computer won’t turn on. Power supply is okay. Is the motherboard bad?
Molex Connector Cut the molex Cable so that you have a black and yellow wire sticking out, for those who don’t know. Yellow wire is the 12v cable and the black one is ground. It is ideal you have something similar to what the picture below shows. Cutting Extension Cable Cut both ends of the Extension Cable so that you have three cables sticking out on both ends.
Apr 05, · If the PC won’t come on, then the monitor won’t come on. The monitor power up is signaled from the PC video drivers. I don’t want to be tacky, but how about telling us something about the PC.
This one handles everything, and has capacity to spare: But what I like about it the most is how quiet it is, very unlike the surplus “server” supplies I was using, which tended to wear me down with all that acoustic racket. I selected these in particular because they were very quiet, with their cooling fans running at speeds matching how hot they get. Most of the time, the fans don’t run at all, but when they do, the slower speeds engage first, and make very little noise.
These individual units are connected in a series-parallel arrangement, and a simplified diagram of this method is shown below: This is just the basic idea This leaves a total of 45 amps more available at any of the 3 outputs. The reason for this is because the very bottom power supply must contribute to each output; it’s capacity is 60 amps, so if it is already contributing 15 amps between the In my own case, this is more than enough, even if I’m running radios, transverters, and a legal limit 50v amplifier at the same time.
The following block diagram shows additional detail: A pair of 30 amp 12v supplies provide the base output The diodes also do a good job of providing current sharing, and the returns of the two units are tied together and routed to chassis ground through a current metering shunt, where the total current from all outputs is measured.
For 28v, the return side of a second pair of 12v supplies set to

By Vin Marshall posted Feb 2nd, at 3: There are easier ways to get a simple power supply like this one re-using a wall-wart, for instance. But if you make a power supply like this at least once in your life, you will have a much better understanding of how alternating current becomes regulated DC power. There will be many other power supplies like it, but this one will be yours. A power supply, as we’ll be referring to it here, converts alternating current from the outlet on the wall into direct current.
An old computer power supply has 12 volt outputs and usually delivers ample current. Here’s more information on how to use one. Places like All Electronics and MPJA sell inexpensive (under $15) surplus switching power supplies that work great if you can figure out how to hook them up.
Its height and width, along with its mounting pattern, continues to be used today in almost all full-tower and mid-tower ATX systems, as well as many microATX and even some mini-ITX systems. In modern computers, the newer EPS electrical standard replaces the older ATX standard, with an 8-pin volt connector delivering power directly to the CPU and a pin main connector powering the rest of the board. The newer EPS connectors are backwards compatible with the older ATX standard and many manufacturers make it so the extra four pins can be separated from the main connector for an easier fit into the old pin ATX and 4-pin CPU headers.
Since the PCIe slots are limited to a maximum power output of 75W, nearly all power supplies include either a 6-pin or an 8-pin connector to provide supplemental power for mid to high-end graphics cards. The 8-pin power connector is compatible with the 6-pin connector, with two pins that split away, to enable its use on less demanding cards. The PCIe connector itself is also shaped differently than the 8-pin CPU power connector in order to prevent accidental misuse.
In this day of SATA-based storage, the four-pin ATA leads rarely hook up to drives, but rather power cheap fans, fan controllers, and other accessories.
BU-405: Charging with a Power Supply
Using a wiper motor in your Halloween projects by Scary Terry Ever since I posted some projects using wiper motors, I’ve gotten a steady stream of email asking questions about how to use them in Halloween devices. There’s a lot of information on the web dealing with wiper motor use in cars imagine that! This page is my attempt to provide some information for how to use them in other devices.
There are more efficient and complex power supplies in the world. There are easier ways to get a simple power supply like this one (re-using a wall-wart, for instance).
You can use an old personal computer power supply to run your direct current RC battery charger. This is useful when you want to charge or cycle a battery pack at home on the bench. You can usually obtain an “ATX” type supply and power cord from the computer support person where you work. They usually have a big cardboard box of these and are happy to get rid of them. Take these instructions in with you so he can get you one just like these pictures.
These instructions are meant to complement the more extensive ones written by Pat Harvey. This makes things seem complicated.

Charging with a Power Supply Learn how to charge a battery without a designated charger. Batteries can be charged manually with a power supply featuring user-adjustable voltage and current limiting. I stress manual because charging needs the know-how and can never be left unattended; charge termination is not automated. Because of difficulties in detecting full charge with nickel-based batteries, I recommend charging only lead and lithium-based batteries manually.
Apr 23, · I need to make a new control panel that contains alot of DC coils and feeds many external DC solenoids. I have most of the parts in our stores but the DC power supplies that i have is not big enougth to feed the circuits.
Comments The other weekend, I sat down and sorted through all my random electronics junk. As part of that process, I took all my power supplies and adapters and threw them into a box. It ended up being a pretty big box. Having so many chargers can be pretty frustrating. And once that happens, it can be incredibly difficult to figure out which goes with which. The default solution to this is to try random plugs until you find one that fits into your device. However, this is a big gamble. If you grab an incompatible power adapter, your best case scenario is that it works, albeit not the way the manufacturer intended.
The second worst case scenario is that you fry the gadget you are trying to power up. The worst case scenario is that you burn down your house. The following will cause damage to your device: Reverse polarity Higher voltage adapter than device rating The following will cause harm to your power cord or adapter: Reverse polarity Lower current adapter than device rating The following might not cause damage, but the device will not work properly:
