Will my motherboard support a PCI Express 2.1 x16 video card?

Here is a link with everything you need to know about my motherboard. I just need to know if it will support a pci 2.1 card

Version 2.1 cards work in all PCI-E x16 slots, regardless of version number. And for cards below the $350 mark, there isn't any performance difference because they don't exceed the bandwidth limit of the original PCI-E x16 spec.



Of course higher-end cards require more power, so you'd need to replace HP's 250 watt power supply to run anything more powerful than a Radeon HD 6450 or GeForce GT 520.

1 PCI Express x16 slot for graphics card



Even if it's only PCIe 1.1, it'll be the same as PCIe 2.1 x8, and you won't notice any drop in performance unless it's a very powerful card ($300+).|||Your motherboard will, but if you have the stock power supply it probably won't.|||yes 100 %

i am also using AMD HD 6450 pci 2.1 x16 video card on PCI Express x16 slot
