#

This is my first pc I don't know why it will not power on all the cables are connected to the power supply but it would not turn on please help

tender juniper Dec 28, 2022, 1:04 AM

#

Oh did you do the small cables correctly? To the power ?

#

The manual describes the small pin cables for the button.

#

The power switch*

#

Also picture please of case as in current state

sharp raven Dec 28, 2022, 1:06 AM

#

@primal ingot pics?

primal ingot Dec 28, 2022, 1:06 AM

#

#

That's after I took the gpu back out

winter harness Dec 28, 2022, 1:06 AM

#

primal ingot

Is the main switch on the back of the power supply turned on and is the power supply plugged into the wall?

primal ingot Dec 28, 2022, 1:06 AM

#

Yes

#

It was after assembled

winter harness Dec 28, 2022, 1:07 AM

#

Why is your 24-pin ATX power and your 8-pin EPS power unplugged?

primal ingot Dec 28, 2022, 1:07 AM

#

So i could get my gpu out

tender juniper Dec 28, 2022, 1:07 AM

#

Well without those the pc does nothing

#

whoa

primal ingot Dec 28, 2022, 1:08 AM

#

Without what?

winter harness Dec 28, 2022, 1:08 AM

#

Those power cables plugged in.

tender juniper Dec 28, 2022, 1:08 AM

#

Without the 24 pin and cpu pin

primal ingot Dec 28, 2022, 1:08 AM

#

Yea they where plugged in

tender juniper Dec 28, 2022, 1:08 AM

#

Get those back in

primal ingot Dec 28, 2022, 1:09 AM

#

They where plugged in and nothing happened

winter harness Dec 28, 2022, 1:09 AM

#

Okay. Link a PCPartpicker list with your ENTIRE system loadout.

primal ingot Dec 28, 2022, 1:11 AM

#

My cpu isn't on it

winter harness Dec 28, 2022, 1:12 AM

#

Okay link what you can and tell us the CPU.

primal ingot Dec 28, 2022, 1:13 AM

#

#

winter harness Dec 28, 2022, 1:14 AM

#

Okay, whoa full stop.

primal ingot Dec 28, 2022, 1:14 AM

#

Does this work

winter harness Dec 28, 2022, 1:14 AM

#

I see a bomb in there.

#

That Thermaltake Toughpower 850. Get rid of it.

tender juniper Dec 28, 2022, 1:14 AM

#

Send it back if you can.

primal ingot Dec 28, 2022, 1:14 AM

#

Why? What's the issue

winter harness Dec 28, 2022, 1:15 AM

#

ThermalTakes have been known to explode.

#

Or just suck in general

tender juniper Dec 28, 2022, 1:15 AM

#

6900 XT is known to have spikes up to 1000 watt power , and is recommended to have a decent psu for it

sharp raven Dec 28, 2022, 1:15 AM

#

He can just undervolt the gpu for now

winter harness Dec 28, 2022, 1:15 AM

#

sharp raven He can just undervolt the gpu for now

Not if it doesn't even power on.

sharp raven Dec 28, 2022, 1:16 AM

#

True

winter harness Dec 28, 2022, 1:16 AM

#

KEKW

tender juniper Dec 28, 2022, 1:16 AM

#

Not powering on could be bad bios

#

As In Not supported for current ryzen

winter harness Dec 28, 2022, 1:16 AM

#

primal ingot Why? What's the issue

Do the fans spin at all?

sharp raven Dec 28, 2022, 1:16 AM

#

winter harness That Thermaltake Toughpower 850. Get rid of it.

Also I use this buckyPride

primal ingot Dec 28, 2022, 1:16 AM

#

No

winter harness Dec 28, 2022, 1:16 AM

#

tender juniper As In Not supported for current ryzen

It's a B550

#

Totally supported

sharp raven Dec 28, 2022, 1:16 AM

#

Missing the plug for the power button maybe

winter harness Dec 28, 2022, 1:17 AM

#

primal ingot No

Show us the front panel headers please

tender juniper Dec 28, 2022, 1:17 AM

#

winter harness It's a B550

Yeah but out of the box? Have to double check bios versions

sharp raven Dec 28, 2022, 1:17 AM

#

It says 5000 series ready

primal ingot Dec 28, 2022, 1:17 AM

#

winter harness Show us the front panel headers please

As I said first pc idk what that is

winter harness Dec 28, 2022, 1:18 AM

#

Okay so refer to your system manual.

#

One second while I pull that up

primal ingot Dec 28, 2022, 1:18 AM

#

Is that the top of the pc

tender juniper Dec 28, 2022, 1:18 AM

#

The cable with 2 pins headed to it

winter harness Dec 28, 2022, 1:18 AM

#

tender juniper Dec 28, 2022, 1:18 AM

#

The power switch part cable

winter harness Dec 28, 2022, 1:19 AM

#

Page 4 of the linked manual, refer to the graphic. Bottom right-hand of the board, designated F_PANEL. That group of headers.

tender juniper Dec 28, 2022, 1:19 AM

#

The gigabyte logo left of it

#

On your motherboard

primal ingot Dec 28, 2022, 1:20 AM

#

#

This?

tender juniper Dec 28, 2022, 1:20 AM

#

Yeah

winter harness Dec 28, 2022, 1:20 AM

#

#

Oh. You have your power switch connected to your CLR_CMOS header

tender juniper Dec 28, 2022, 1:21 AM

#

whoa

primal ingot Dec 28, 2022, 1:21 AM

#

Idk what that is

#

Where does that go

tender juniper Dec 28, 2022, 1:21 AM

#

Well remove that cable

primal ingot Dec 28, 2022, 1:21 AM

#

Removed

#

Now where does it go

winter harness Dec 28, 2022, 1:21 AM

#

primal ingot Now where does it go

Look at the page I posted.

primal ingot Dec 28, 2022, 1:22 AM

#

What's that

tender juniper Dec 28, 2022, 1:22 AM

#

Find a cable which says pw switch

#

It must have text on the flat part of the cable

#

The plug I mean

#

What does it say?

primal ingot Dec 28, 2022, 1:22 AM

#

rn_image_picker_lib_temp_3dbbf121-90a9-48aa-9ad8-91d714d11338.jpg

winter harness Dec 28, 2022, 1:22 AM

#

That one.

primal ingot Dec 28, 2022, 1:22 AM

#

Ok

winter harness Dec 28, 2022, 1:23 AM

#

Now that white block of headers.

#

On the top row of pins.

#

Connect that cable to the third and fourth pins on the top row.

tender juniper Dec 28, 2022, 1:23 AM

#

from left skip 2 pins , text upright and connect to pin 3 and 4

primal ingot Dec 28, 2022, 1:23 AM

#

#

This?

winter harness Dec 28, 2022, 1:23 AM

#

Yes.

primal ingot Dec 28, 2022, 1:24 AM

#

And connect where?

tender juniper Dec 28, 2022, 1:24 AM

#

Top row

winter harness Dec 28, 2022, 1:24 AM

#

Third and fourth pins on the top row

#

Look at this picture for clearer guidance

#

primal ingot Dec 28, 2022, 1:24 AM

#

rn_image_picker_lib_temp_8121b418-a648-40d9-aae2-3626f1178d8f.jpg

winter harness Dec 28, 2022, 1:24 AM

#

That's right.

#

Now

tender juniper Dec 28, 2022, 1:25 AM

#

Should be working

winter harness Dec 28, 2022, 1:25 AM

#

Connect your power LED cable to the pins left of that.

primal ingot Dec 28, 2022, 1:25 AM

#

I don't have that

tender juniper Dec 28, 2022, 1:25 AM

#

Find more cables like this there should be more

winter harness Dec 28, 2022, 1:25 AM

#

You should.

tender juniper Dec 28, 2022, 1:25 AM

#

Just follow where this cable came from

primal ingot Dec 28, 2022, 1:25 AM

#

rn_image_picker_lib_temp_e182a3b6-40c6-4358-b6c4-32ead0718e5a.jpg

winter harness Dec 28, 2022, 1:25 AM

#

Oh what the hell.

#

Okay this guy is totally lost. That's a FAN and RGB hub.

primal ingot Dec 28, 2022, 1:26 AM

#

That's where it came from

tender juniper Dec 28, 2022, 1:26 AM

#

Follow the switch cable

winter harness Dec 28, 2022, 1:26 AM

#

primal ingot That's where it came from

You see the power button on the case?

#

Look for wires coming out of THAT area.

primal ingot Dec 28, 2022, 1:27 AM

#

This area right

rn_image_picker_lib_temp_f9a71842-2b1d-4058-916e-8fba99fdd11e.jpg

tender juniper Dec 28, 2022, 1:28 AM

#

There should be more loosse cables there

winter harness Dec 28, 2022, 1:28 AM

#

That looks right. Find all the little 2-wire cables.

primal ingot Dec 28, 2022, 1:28 AM

#

All of them are connected at one point at the back

tender juniper Dec 28, 2022, 1:28 AM

#

Well follow the cable we just connected

#

With your hand and keep your eye on it

#

It should lead to the power button

winter harness Dec 28, 2022, 1:29 AM

#

Okay, full stop

#

Get out your case manual.

primal ingot Dec 28, 2022, 1:29 AM

#

rn_image_picker_lib_temp_251a186e-d082-4882-b1f4-465f6633dac8.jpg

#

This

winter harness Dec 28, 2022, 1:30 AM

#

Stop. Get out your case manual.

#

Now

primal ingot Dec 28, 2022, 1:30 AM

#

Ok

tender juniper Dec 28, 2022, 1:30 AM

#

Might be better whoa

winter harness Dec 28, 2022, 1:31 AM

#

https://lian-li.com/downloads/LANCOOL_205MESH_User_Manual.pdf

#

primal ingot Dec 28, 2022, 1:31 AM

#

Ok I have this manual

winter harness Dec 28, 2022, 1:32 AM

#

Okay. So that cluster of wires coming out of the front

primal ingot Dec 28, 2022, 1:32 AM

#

Ok

#

What about it

winter harness Dec 28, 2022, 1:32 AM

#

There should be a two-wire cable coming out of it that does say POwer SW.

primal ingot Dec 28, 2022, 1:33 AM

#

Yes the one I plugged in already

winter harness Dec 28, 2022, 1:33 AM

#

It should NOT be leading back to the RGB/Fan HUB but let's make sure.

primal ingot Dec 28, 2022, 1:34 AM

#

Nope it leads to the top

winter harness Dec 28, 2022, 1:34 AM

#

Okay. Plug that one in where we told you.

tender juniper Dec 28, 2022, 1:34 AM

#

Yeah it’s the correct wire , guess this case does not have led wires

primal ingot Dec 28, 2022, 1:34 AM

#

Done

winter harness Dec 28, 2022, 1:34 AM

#

Okay. Is your GPU installed?

primal ingot Dec 28, 2022, 1:34 AM

#

I'll have to put it back in but rq

winter harness Dec 28, 2022, 1:35 AM

#

Okay. Go for it

primal ingot Dec 28, 2022, 1:35 AM

#

primal ingot

What about this wire?

winter harness Dec 28, 2022, 1:35 AM

#

That is the control cable for the fan hub. Connect it to the System Fan 1 header

#

Actually, no. Connect it to the fan header next to the F_Panel connector. That will be a shorter and cleaner run.

#

SF1 is at the back of the case.

primal ingot Dec 28, 2022, 1:37 AM

#

Ok done

winter harness Dec 28, 2022, 1:37 AM

#

Okay. Now is your CPU cooler connected to the CPU Fan header on the motherboard?

primal ingot Dec 28, 2022, 1:38 AM

#

rn_image_picker_lib_temp_25e96d41-6d25-4f3a-8709-f24b4a51f268.jpg

#

This?

winter harness Dec 28, 2022, 1:39 AM

#

Okay good. Make sure everything else is connected and installed and then hit the power button

primal ingot Dec 28, 2022, 1:39 AM

#

This?

rn_image_picker_lib_temp_9b1445aa-a02b-484f-8570-1b6245524b22.jpg

winter harness Dec 28, 2022, 1:40 AM

#

That is power for the fan hub. It needs to be plugged in to a SATA power cable from your power supply.

primal ingot Dec 28, 2022, 1:51 AM

#

Still not turning on

#

@winter harness @tender juniper

winter harness Dec 28, 2022, 2:00 AM

#

All of your power cables are plugged on the motherboard? Are any fans spinning?

primal ingot Dec 28, 2022, 2:01 AM

#

No

#

All powercables are connected

winter harness Dec 28, 2022, 2:01 AM

#

Is the power circuit this computer is connected to turned on?

primal ingot Dec 28, 2022, 2:02 AM

#

Please explain this

#

Like the switch?

winter harness Dec 28, 2022, 2:02 AM

#

Like the fuse or breaker

sharp raven Dec 28, 2022, 2:02 AM

#

Is the power on @primal ingot

primal ingot Dec 28, 2022, 2:02 AM

#

That's power off right

sharp raven Dec 28, 2022, 2:03 AM

#

That’s on

winter harness Dec 28, 2022, 2:03 AM

#

That's power on. That looks good.

primal ingot Dec 28, 2022, 2:03 AM

#

It's like that

sharp raven Dec 28, 2022, 2:03 AM

#

Guess his PSU wasn’t on

#

Lmao

primal ingot Dec 28, 2022, 2:03 AM

#

No it's on

sharp raven Dec 28, 2022, 2:03 AM

#

Oh

#

02Sip

winter harness Dec 28, 2022, 2:03 AM

#

Okay. Flip that switch and hold the power button on the case down for 10 seconds

primal ingot Dec 28, 2022, 2:04 AM

#

Nothin

winter harness Dec 28, 2022, 2:04 AM

#

Yeah, that's intentional.

#

Trying to force the PSU to reset.

#

While we are at it, show me where the computer is being plugged in to AC.

primal ingot Dec 28, 2022, 2:06 AM

#

rn_image_picker_lib_temp_17586778-9f66-437e-b563-b6956f68e9e5.jpg

#

Also how do I force reset

winter harness Dec 28, 2022, 2:07 AM

#

Can you try plugging something else into that outlet and seeing if it works, like a phone charger?

primal ingot Dec 28, 2022, 2:08 AM

#

Works

#

Phone charger

sharp shore Dec 28, 2022, 2:09 AM

#

hey, guys just jumping in here so i havent read everything but from your original photo it looks like the 24 pin power was not plugged in, have you connected that?

primal ingot Dec 28, 2022, 2:09 AM

#

Everything's plugged in

winter harness Dec 28, 2022, 2:09 AM

#

sharp shore hey, guys just jumping in here so i havent read everything but from your origina...

Don't TL;DR this.

#

Okay, turn the switch on the PSU back on, and press the power button on the case again

primal ingot Dec 28, 2022, 2:10 AM

#

Nothing

winter harness Dec 28, 2022, 2:11 AM

#

Make sure the cable is firmly seated on the back of the power supply.

primal ingot Dec 28, 2022, 2:11 AM

#

It is

winter harness Dec 28, 2022, 2:11 AM

#

Okay. Time to check the power supply itself. Make sure all of the modular cables are properly plugged in

#

And sniff around that for the smell of the magic smoke

primal ingot Dec 28, 2022, 2:12 AM

#

They are

winter harness Dec 28, 2022, 2:13 AM

#

Double check them. Double check that every cable is plugged in to the correct ports on that power supply

primal ingot Dec 28, 2022, 2:13 AM

#

Everything

#

Nothing

winter harness Dec 28, 2022, 2:13 AM

#

Okay. That power switch that we told you to plug in

primal ingot Dec 28, 2022, 2:13 AM

#

Yea

winter harness Dec 28, 2022, 2:14 AM

#

Remove it and use a screw driver to bridge those two pins.

primal ingot Dec 28, 2022, 2:14 AM

#

Ok gotta remove the gpu rq

#

Done

winter harness Dec 28, 2022, 2:17 AM

#

Do the fans spin?

primal ingot Dec 28, 2022, 2:18 AM

#

Do I gotta put the gpu back in and turn it on

winter harness Dec 28, 2022, 2:18 AM

#

No. Just bridge those two pins and see what happens

primal ingot Dec 28, 2022, 2:18 AM

#

Nothing

winter harness Dec 28, 2022, 2:19 AM

#

Okay. Dead, likely power supply.

sharp shore Dec 28, 2022, 2:19 AM

#

did you use a metal screwdriver?

primal ingot Dec 28, 2022, 2:19 AM

#

Yes

winter harness Dec 28, 2022, 2:20 AM

#

Okay. Sounds like you have a hardware problem that needs to be traced down.

primal ingot Dec 28, 2022, 2:20 AM

#

Should I just take it to someone tommorow

winter harness Dec 28, 2022, 2:20 AM

#

I imagine it's likely Power Supply. I would take it to someone tomorrow.
