## Questions & Answers

**Q: how many fan headers does this motherboard have?**
A: This board includes 3x chassis/water pump fan connectors, 1x CPU fan connector, and 1x CPU/water pump fan connector

**Q: Does this board support ryzen7 1700x ?**
A: Hi, I have the same MB B450M Steel legend and Processor 7 2700x. Can you please tell me what model/brand of memory RAM are you using on this MB and also the GPU graphic card model ? I have some issues with my GPU at the moment.  Thanks

**Q: do you need to make it work with a disk? because my case doesnt support disk and any way around this ?**
A: You should visit the manufacturer's website and search for this product.  In that product's support link, you can find the installation guide.  That ought to answer your questions about how to get it working.

If your concern is it might need a DVD drive, it should not.  Almost all new motherboards work with Windows 10 without any additional 3rd party drivers.  

Once Windows is installed, I'd recommend going to that same motherboard support page and download the manufacturer's drivers and most recent BIOS, in case their drivers are different than Microsoft's. Follow the directions to install those, and you'll be done with the motherboard installation.

**Q: Does it have a pcie x16 slot?**
A: Yes the first one which is metal
