ask about riser card

[iqacid]

Hey guys

i bought new MB "MSI B75A G43" and it support 2X  PCI Express 1X too 16X and 2X PCI Express 16X to 16X

So I have just 4X PCI Express 1X  and my question is can i  put em into either the 1x or 16x slot on the motherboard?

merry christmas btw and sorry for my bad english 

thanks

So far i know 1x should be work in even in 16x but i have read that some people burned mother board that way.
But its more related that how much power can your mother board hanlde. If you have weak PSU i think then sometimes power can be supplied by motherboard beacouse those 2x PCI-E cable wont support so much power. You can consider and buy  "PCIe Riser Cable 1x/16x w/ Molex Power Connector" (google it).
