Question Swapped parts and PC won’t turn on now

[JCarroll301]

I replaced my mobo & cpu with ones from a friend that worked perfectly and now the PC shows no lights and won’t turn on at all. I don’t have it fully put back together (GPU isn’t in & USB 3.0 header isn’t) but everything else is there.

Gigabyte B560M DS3H
i5-11600K
Gskill 16gb ram (one stick)
Corsair 750W PSU (I think, can check if needed)

Also Gigabyte 3070 8GB but it’s not in rn

I’ve tried removing and putting the ram back in and same for the cables. I tried jumping it using the 2 pins on the mobo. And I tried taking the cmos battery out and back in, which did work the first time but then I left for a couple of hours and came back and now that wont work.

The only way it will turn on is by using the paper clip trick in the 24-pin cable.

Welcome to the forums, newcomer!

Corsair 750W PSU (I think, can check if needed)
Corsair is the brand of the unit, while 750W is the advertised wattage of the unit. What is the model of the PSU and how old is it?

On second thoughts,
Gigabyte B560M DS3H
i5-11600K
Gskill 16gb ram (one stick)

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time. We'll be seeing two sets of specs, one for before the swap and one for after the swap.

The only way it will turn on is by using the paper clip trick in the 24-pin cable.
That is a flawed test, since that doesn't tell you how much power the PSU can effectively output to the system.

Thanks for the warm welcome!

I’m pretty sure every part that I had originally and from my friend were all bought in late 2020. Besides the GPU & Monitor which were purchased last year. And the cooler is brand new.

CPU: swapped to i5-11600k from i5-10400
CPU Cooler: Phantom Spirit 120SE RGB
MOBO: went from ASRock B460M Pro4 to now a Gigabyte B560M DS3H
RAM: 1 stick of GSkill Ripjaws 16gb DDR4
SSD/HDD: WD 1TB SSD which is my main & I have an older HDD plugged in the lower section of the case that I can get out if needed.
GPU: Gigabyte 3070 8gb
PSU: Corsair CX600M
Chassis: Montech case from Amazon that I have not been able to find on there again, I’ve looked before.
OS: Windows 11
Monitor: LG Curved 34” Ultrawide WQHD 3440x1440 from Walmart app

So the bios on my previous mobo was up to date but I’m not quite sure how up to date the one I’ve switched to is.

There is no way. The listed went to motherboard is AMD and you mention getting an 11600K.

Also would mention that the CX600M is a non modular power supply, according to age, and the 750 most commonly is or at least partially so.

I can look around and see. I googled it myself and the mobo I mentioned looked very similar if not exactly the same, so one moment. And having a 750 was just me misremembering, my bad.

Corsair PSU often use the same cables when modular, but not always. There should be some printing on one side that would say such as "Type 4" indicating which PSU they fit.

If you haven't damaged your hardware, you might wish to take a look at the motherboard you had with the 10th gen in it and see if there is a BIOS revision for the 11600K. If in some way you managed to put that CPU into the wrong socket and try it then there is no telling what damage may have occurred to both pieces.

I just edited my original reply. It’s a 560 not a 650, got the numbers mixed up. And I swapped mobo’s because my previous one wouldn’t support the 11600K.
