[SOLVED] PCIe lanes and using PCIe x1 in a PCIe x4 slot ?

[nonag]

Hi All

I'm building a PC with this Gigabyte B450M DS3H (AMD Ryzen AM4/M.2/HMDI/DVI/USB 3.1/DDR4/Micro ATX/Motherboard).

The current set up looks like this:

1. Gigabyte B450M DS3H (AMD Ryzen AM4/M.2/HMDI/DVI/USB 3.1/DDR4/Micro ATX/Motherboard)
2. AMD Ryzen 3 3200G 4-Core Unlocked Desktop Processor with Radeon Graphics
3. Crucial P2 500GB 3D NAND NVMe PCIe M.2 SSD - CT500P2SSD8
4. Crucial Ballistix 3000 MHz DDR4 DRAM Desktop Gaming Memory Kit 16GB (8GBx2) CL15 BL2K8G30C15U4W (White)
5. Gigabyte GeForce GTX 1660 OC 6G Graphics Card, 2X Windforce Fans, 6GB 192-bit GDDR5, Gv-N1660OC-6GD Video Card

The graphics card (gtx 1660) will attach to the PCIe x16 but will also cover up the PCIe x1 slot just below it.
There is a remaining PCIe x4 slot, if there is enough room would I be able to attach a wireless/bluetooth card with PCIe x1 interface to the PCIe x4 slot ? Or am I better off going with the a USB version of a wireless/bluetooth card ?

About the PCIe lanes I don't understand this whole thing. The Ryzen 3200g CPU has 20 Lanes, the MOBO has 28 lanes and I don't know how many lanes the GPU & the NVME M2 memory takes up. Are there enough PCIe lanes for this in this set up above so there is not going to be any sharing?


Thanks!

dont worry too much about lanes, unless youre planning on putting a multiple GPU's in, it wont matter.
as for wireless card, i would recommend getting a powerline adapter before a wireless card, but if its impossible, then the different is negliable between a pcie card and a usb one

An x1 card will work fine in an x4 slot. WIFI does not use much bandwidth (relative to what PCIe provides).
