Explanation

PCI Express is designed to be backward and forward compatible across versions. A PCIe 1.1 card will physically fit and electrically function in a PCIe 2.0 slot. The card will negotiate down to the PCIe 1.1 speed rather than running at PCIe 2.0 speeds, but it will operate correctly. PCIe versions share the same physical connector design, so there are no slot incompatibility issues between 1.1 and 2.0.
