You can't make a x1 slot run at x16 bandwidth. You can only make it physically bigger with such a cable. And yes, they exist as they were used by the crypto miners not that long ago.

 

Just look around for PCIe x1 to PCIe x16 riser.

Is a pci 1 to 16 adapter with power cable equal to a normal pci 16? and if not, by how much?

Exactly, it will run at 1X speeds and you will NEVER get 16x speeds.

It will run at 1x, physical limitation

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

Some motherboards don't provide enough power to pci-e x1 slots - they're only required to provide 10 watts.

For bigger slots, the limits are 25w and 75w (for video cards)

 

The risers which have separate power connector simply allow you to "boost" the power in case the motherboard doesn't give enough power by default.

It makes it possible to use a video card in a pci-e x1, without BIOS complaining about "power limits exceeded" or fuses tripping on the motherboard.

 

The data part of the connector remains x1, so anything plugged in the x16 slot you created will still function at pci-e x1 speeds.
