These show which color wires on the PSU to short together to start the supply. But the issue is: How do you turn on the power supply? In fact, inside the computer, power up is done via the motherboard. It sends an activation signal to the supply whenever you press the Power button on and off. So how do you create such a signal yourself without a computer?
We cover that below. For most of these PC supplies on the market today, the motherboard communicates with the power supply module via the or pin cable that connects the two together. To activate the full-current capable part of the power supply, the motherboard connects the pin with the green wire on it to ground.
You can do the same by manually connecting this green wire to any one of the black ground wires in the same connector. Most of these units contain at least one internal fan that will spin up when the high-current portion is energized. What a shame said:. I'm just going to guess that your PSU is just dead.
Did you manage to turn it on standalone? Flick the switch on it off, probably waiting a minute and flick it back on. Will unplugging and plugging in back the power cable do the same thing? Does the paperclip stay in the cables?
No, insert it for a split second, that's enough. Another thing, I noticed when I plug the HDD cables sata and power my power button LED flickers, but when I unplug the cables or just connect one of them the flicker stops. I used another sata cable to check if it's the culprit but it keeps flickering.
Is it possible the cable from the psu to the HDD is somehow not working properly? I'm trying to claim the warranty for this psu but I'm not sure what the damage description should be because it's now working again, but I know it'll start turning off again in a few days just like before.

Just say that it's unstable. Can heat affect it? But doing a power cycle would turn it back on. You must log in or register to reply here. Post thread.

If you have an older style connector with multi-coloured wires, you can identify ground pins as those with black wires connecting them. Remember, as soon as you connect the two pins, the PSU will start to power anything that's plugged in, so make sure it's either off at the wall or at the back of the PSU beforehand.
When you flick the switch on with the paper clip in place, it will power up. Touching the paper clip won't actually hurt you, but do be mindful that you don't knock it out by accident. The second option is a little tidier and far better if you are building multiple systems or want something more permanent. Yes, this one is called the male connector, even though the PSU's connector fits into it.
It takes its name from the terminals that fit inside it. If in doubt, just look at what your pin connector looks like and get the opposite connector. It should look like the one that is on your motherboard. Cut the wire so that it is around 60 mm long, just the same as we did with the paper clip. Next, grab a couple of male terminals, strip a few mm of insulation from the wire, and crimp the terminals to the end of the wire. So, you can now power your pump, LEDs, or anything else without having to have power coursing through your motherboard - winner!
