Hi I need help on figuring out why there’s no power in my computer
I’m building a new pc and built 2 in my lifetime
This is the first time I encountered a front panel connection all in one socket
I suspect I needed an adapter
Any ideas?
Pc case is Lian li lancool 216x
Motherboard is gigabyte b650 gaming ax
I’ve included 3 photos

Updated refer to my last post
Last update
As my last resort after researching in google
I found out some motherboards doesn’t power without the cpu fan on or with cpu and cpu fan (maybe to avoid frying? Who knows xd)
I installed the cpu/cpu cooler/ram and 1 stick of m2
And it powered on the first go!
Going to install my gpu tomorrow morning
Ty all for helping =)
*SOLVED*HELP-No Power on Computer

If that really is the front connector then you might need to cut off the wires and crimp them into a connector like the old cases use to be.

Any idea if they sell an adapter for those? That’s the old connection I remembered from my last computers .
I’ve read online that pc case manufacturers release their own front panel connectors nowadays. This lian li company does apparently.
Will update after work.
Short the two PW pins on the motherboard with a screw driver and if it powers on you know the switch is the issue.
I will try this later when I get home from work
I’ll update with the results
Did you turn on the power supply/power point?
This one always gets me haha.
I'm also guilty of forgetting to turn them on…
Yes! Haha
I’m sure there’s power from the psu to the motherboard
Because when I press the quick bios flash button the front fans spun for a few seconds and a led light turned on .it’s normal coz I didn’t put any usb to flash.
That'll only help if you've paid the bill.
you should always bench test the pc before placing in the case
I know I just assumed it will work like before
This my 3rd system I’m building in 15 years
I must’ve missed something
updated
Are there any lights flashing (or sounds beeping) in a pattern?
There might be a pinout diagram with the case or on their website, and you could use some pins from jaycar to attach the wires separately to the MB?
No power at all no lights no sound
I thought I read that the fans started spinning
Because when I press the quick bios flash button the front fans spun for a few seconds and a led light turned on .it’s normal coz I didn’t put any usb to flash.
Sorry, I skimmed through, but the above may help later.
UPDATE
I tried to shortened the motherboard
No power still
I think I’m not connnecting the right plugs to power the motherboard ….
I took out all the wirings and only kept 1 fan at the front and when I press the quick flash button it spun
So I assume the psu is providing power to the fan but not the mainboard.
Here is the photos for the motherboard power connections

My concern is the connection on the top left
I encircled it
It has 8 pins and 4 pins
I’ve inserted the 8 pins correctly
But the 4 pins I don’t have a stand alone wire for it
My one is 2 x 4 pins as shown in the picture
And I try using just one of them since it fit?
Do I have the wrong plug for it and needed a single 4 pin connector only?
My psu didn’t provide any other connectors I only got the pcie power cables and one pcie 5 cable (600w) for the gpu.
All cables are labeled.
Anymore ideas anyone?The 8 pin CPU socket is all that's usually required - your motherboard manual says as much, just connect that and not worry about the 4 pin CPU connector. The 4 pin CPU socket is likely either only for extreme overclocking or to connect to legacy power supplies that only have a 4 pin CPU connector.
From the pictures it looks like you've plugged a GPU 8 pin connector into the CPU power socket on the motherboard, this is not the way. You need to link those 2 x 4-pin CPU connectors together (from the power supply) to make an 8 pin cable, and plug that into the motherboard - this will be your problem. You've got half of it plugged into the 4pin socket, disconnect both those cables from the motherboard, connect the 2 4 pin cables together (they kinda lock into place) then connect that 8 pin connector (the 2 x 4 pin CPU ones) into the 8 pin socket on the motherboard.
Your FPANEL connector may not be the right PINs your motherboard requires, eg the motherboard is expecting a power switch to be connected to the 2 red pins, the FPANEL connector may be using that as a LED - you'll need to check the case manual to see, or follow the wires back.
You can carefully short (temporarily, like tap it) the two RED pins on the motherboard's front panel connector - this will be same to the motherboard as pressing the power button it's expecting. It should fire up doing that if all is well.
I was about to reply with is the cable(s) fully plugged into ATX_12V (8 Pin),, as well as the CPU cable into ATV_12V1?
(Like you weem to be also suggesting).
Still no joy but your explanation is really good.
Can’t short doesn’t work
It’s tapping the 1st 2 red pins with a screwdriver?
Just got back from the shop to pick up my rams
I asked about it and he said I didn’t plug it wrong it’s all standardise now etc I have to connect the front panel connected to the left most.
I’m suspecting my psu is faulty?
It’s brand new a be quiet! One (1000w) in this case it’s too quiet for my liking.
I’ll keep trying tonight
If no luck I’ll bring the psu to the shop where I bought it to see if it’s working
It looks like hes rammed an 8 PIN GPU (PCIe) power cable into the CPU EPS-12V socket - which shoudltn have fit without a LOT of force, which is sending power to ground for most of the pins…. im 99.5% sure this is why its not working :)
No I didn’t
All plugs i used is labeled CPU (be quiet psu)
It’s hard to force it as the plugs can only goes one way .it got patterns
That front panel connector doesn't look it has enough cables going into it? (photo 2)
That happened to me once. The front panels for my cases have a separate socket for each wire rather than a block of sockets such as for your case. I had accidentally connected the wrong socket to the wrong pin on the new mobo. Luckily each socket had a marking to describe its function. I checked the mobo booklet, rewired to correct and it worked.
Do you still have the old mobo? If so, compare the pin configuration with the new mobo. If they are different, then you have the reason.
Can’t be the mobo
I couldn’t short the new motherboard on both psu
It means it’s not getting power at all =\
Im running out of ideas
I even tried using my old psu
Same problem
Can do quick flash bios update via usb
Still no power on the motherboard (can’t short and no front panel button function)
I’m pretty sure I’m doing it right.2 psu can’t be both faulty…..what else could I miss ….unless this connector pin from motherboard is faulty.I know the 24 pin connector on the right is working because the fan works
Problem solved
I installed cpu/cpu cooler/ram/and m2 drive and it came alive.
Ty all for helping.
To everyone I guess not every mobo can self test without installing cpu/cpu fan first and maybe with ram.Wait, 'I installed CPU, cooler, ram and m.2 drive then it worked'. So you tried to power on a system without CPU and RAM? Or am I missing something lol.
Yes
I’ve read that you can test mobo if there’s power without cpu/ram
You just need the psu and plug the power connectors then short the power pins
I think my fault is assuming that all mobo supports this function as I’ve read heaps of same problem like me.
It’s also clear in one of the photos that I didn’t installed any component on the mobo.
Sorry if anyone missed that.That’s completely incorrect, I think you’ve got that mixed up with BIOS flashback which is what you can do to reflash a bios without a cpu installed.
@iDarelones: I’m not sure if this allowed but I read it from here
https://tech4gamers.com/how-to-test-motherboard-without-cpu-…
Then last night I’ve read somewhere that not all mobo support this.
Good you could get it to work.
Most people would normally install all components then test to see if it works.
Why bother to try to test mobo by itself especially if it is a new build? If it is new, the assumption is it should work. Only if there is a problem after complete assembly should you bother to problem solve.
Dude glad you got it working, but would have been good to know (maybe I missed it) that you hadnt installed CPU or RAM…. shit wont fire up without those! :)
Cheers
Red is power on. Short it with a screwdriver to test if the CPU, CPU fan, RAM, mobo and PSU work. Do it on your motherboard box before installing the components.
Are you sure you're not plugging in the USB cable? lol
