Is PCI compatible with PCIe 2.0

Jacob McIntosh · Aug 24, 2013

I am building my own computer and have an older sound and wifi card that are both connected to my MoBo in a PCI connection. If I get a new MoBo with PCIe 2.0 x16 connections, will my old cards work?

If it has a legacy PCI connection, yes but you should check for that.

They are different slots. No

PCI and PCIE are different architectures.

Most motherboards still have one , check to see when you purchase.

Sorry, no.

PCIe 1.0, 2.0, and 3.0 are all compatible. PCI is a different physical slot than PCIe and if your NEW mobo does not have PCI slots then it couldn't accept your existing PCI cards. You can buy a new mobo with both PCIe x16 connections AND PCI slots.

Thanks for the help so far. I have found a new wifi card but it is PCIe. will this work in one of the 2.0 slots? btw i am looking at a Sabertooth 990FX/GEN3 R2.0 mobo. I need the PCIe 3.0 for a new gpu card, and the PCI slot for my old sound card. from here there are only 2.0 and 3.0 slots left

PCIe is universal, just check if the board has a couple of x1 lanes and youll be fine.
