Question My Z220 doesn't receive any power with a 24pin to 6 pin adapter I used with a new psy

[Oogaboogaaa]

Hi I would really appreciate ur help. So I got a gtx 1060 3gb and it needed a 6 pin pcie and higher watt output from the Psu so I got a better psu with a 6 pin pcie but my Z220 sff workstation only has the 6 pin and the small 6 pin instead of a 24 pin that the Psu has, so I figured I'd buy an 24 to 6 pin adapter but it didn't work when I plugged it to the Psu and the pc. I tried messing with the small 6 pin colors and tried resetting the cmos but the little light between the ram sticks never turned on and the pc doesn't boot. Please I would appreciate any kind of help!!! And thanks in advance

Please link to the parts you have used.

From what I can see it is more than a 6-pin, there is an additional inline connector with another six pins. If your adapter doesn't have that, it probably won't work.

Note the white connector to the right and a little down.

Does it still work if you plug the original PSU back in and remove the new GPU?

You are also at that weird point where GPUs start needing UEFI BIOS and that system may not have one.

Hi I used a chinese non branded 450w psu and the GPU that requires 6 pins is removed for now and I'm testing if it would work with a normal GPU that worked with original sff psu. And I tried an old psu with 110v mode and instantly exploded but when I plug original psu everything works fine. I can't test if the new Psu is working cuz it has no power switch and the pc doesn't show any signs of power connected to it, the light between the ram sticks stays off. And the adapter I used is this one https://fr.aliexpress.com/item/1005006464766409.html?gatewayAdapt=glo2fra

Can u please figure out something cuz I have finals in 3 days and I don't want to study knowing that all the parts I gathered dont work together and thank you so so much!!!

As long as both cables are plugged in I don't see a problem, unless they screwed up the wiring.

I assume you don't have a 110V power then, yeah, that PSU is toast then.

You can fire up the other PSU (without it being plugged into the computer) by shorting the Power On pin to ground.

https://en.wikipedia.org/wiki/ATX

Scroll down to the 24pin connector diagram, see pin 16, and orient the cable end in the same way as the picture to the right. Short Pin 16 to 15 or 17 using a piece of wire, a paperclip, anything metal you can get in there. You should see the PSU fan spin up, which is a good sign. But really you need a voltmeter to do a simple test. PSUs can really only be properly tested under a load (ie computer, or specialty test equipment)

If that works, and the power button on the chassis doesn't turn on the system at all, then you can also permanently short the power on wire to ground so that the PSU is always on. Makes shutting down the computer a bit weird since you basically have to pull the plug or using a switch/power strip. But it may also force start the system.

OK thanks but supposing it works, so you have any idea of why the pc doesn't receive any power and it is as if nothing was plugged into it, and the power button of the pc works completely fine when I plug the original psu so I think the problem is either the Psu or the adapter isn't transferring the power to the pc and Thanks again!! (the light between the ram sticks is always off with the new psu)
And BTW if I have the 24 pin connected to the adapter, how would I have the paperclip in the thing

I've only messed with a Dell one time. But I did build my own adapter using an old dual six-pin to 8-pin PCIe adapter cable.

The proprietary front panel connectors are what usually get you in trouble. I'm not sure about HP, but it is possible they have a signal coming from the motherboard that is non-standard to ATX and doesn't make a regular PSU turn on.

On the Dell they use a combo start/shutdown/reset button that is also the power LED. Never did figure out how that thing was supposed to work, so I wired the PSU to be permanently on. On that particular system I went to the trouble of turning off ACPI so that the system behaved in the old way of "Your computer is now safe to turn off", rather than going into standby mode like modern ATX systems do.

If that PSU actually works, and you can get it to turn on by shorting the power on signal to ground, then the next step would be to connect a wire between power on and ground on wire side of the connector(back) so you can still plug in your adapter.

Only other thing would be to figure out the pin out and see if that adapter was made properly. Not really something I can walk you through on a forum though.

Hey thank you so much for your time and I will try my best to follow ur instructions and sorry for the disturb!!

If OP has a voltmeter with original power supply working on system is to back test the 6 pin to motherboard plug while system is on and working.

Just make a cheat sheet on paper as you get a reading from pin to pin what pin has what voltage.

If you can get the new power supply jumpered OUT of the system and with the adapter again make a cheat sheet of what pin has what voltage.

Than do a side by side and see if they match.

Keep in mind that you have to pay attention how your looking at the power supply with the pig tail while testing. Put in your head the correct orientation of that pig tale being plugged into motherboard or your readings will be off.

Hi i tried a different psu but at least it gave power to the pc , it turned out that chinese psu wasnt working . anyways with the different psu i was getting 4 beeps then a pause then 4 beeps with red light on the power switch ,
here is my motherboard https://i.ebayimg.com/images/g/0-MAAOSwNoxkBut4/s-l1600.webp
but i was not able to find what 4 beeps mean on my current motherboard bios . anyways putting back the original sff psu makes everything work like normal .
Thanks again !
