Looking at the previous post, I was a bit confused, the CPU cable plugs into the top of the motherboard, the GPU is the long card, it normally uses a 6 or 8 pin end cable.
The members who replied recommended a cable extension kit which would help you fix this issues. However if you're going to look for a new motherboard, you may want to look into what price mark you'd like, the cpu platform you'd like to use?
In my opinion I'd recommend an AMD platform. They're affordable and then if you'd like AMD you need to work on which OS you'd like to use. Windows 11 which is the current main OS (Windows 10 is EOL).
Windows 11 Intel supported CPU
Windows 11 AMD supported CPU
Then go and look for a motherboard which has the same socket as the chip. For example:
AMD Ryzen 3 3200G
The AMD Ryzen 3 3200G has an
AM4 socket.
So I would use the:
ASUS ROG STRIX B550-F GAMING WIFI II - Motherboard.
Reason being, it has a AM4 socket for the CPU above, it has Wifi 6e support, so you don't need to plug in an Ethernet cable or a wireless card, it has USB 3.2 not the latest but near enough. 4 ram slots, so if you wish to upgrade the system in the future with more ram you can. M.2 slots for M.2 SSD if you would like to use one for the boot drive for Windows.
And the main point for everyone especially new builders, BIOS flashback, so if you need to update the Bios, you download the files to a USB, plug it into the BIOS USB slot, press the BIOS button and it does the hard work for you.
Then the rest can come after, personally however I do recommend you buy a Modular or Semi-Modular power supply. It'll make your life easier and you can only use what you need, want a 8 pin cable, there will probably be one in the box.
PS: You can find some offers on eBay and buy the auction prices, but Amazon is next day delivery, sorry mine are linked in the UK, however you can find them on the USA one.
