4x PCIE Riser Splitter

I have a single pcie x1 slot, i was wanting to install a wifi card and usb 3.0 card. Could i use this splitter to accomplish that?

Will this work on the h61 motherboard of ant Value?

Does the molex power to this board supply all the risers eliminating the need to power each?

Did you get hashes thru all of those 1x multiple by 4 thru that 1x lane ? ( Assuming your mining here )
Looking into a CPU that supports 128 lanes, and this is a life saver product if it worked for lower demand stuff like sending hashes from mining thru, or serial attachments and USB 2.0 - 3.0+ protocols !
Full expansion!

how do you find out how many cards can be used on a single motherboard? Does it depend on the CPU lanes?
