Before I purchase a new video card (current one died after a few years) I was trying to figure out if I could use a PCI express 3.0 with the motherboard and power supply (listed below) would work with it. I'd like to just build a whole new computer but my funds are short at the moment. I know they are backwards compatible. But does the motherboard have enough power for the connection. I just didn't see that with the specs. Does anyone have an idea on this before I make the purchase? Thank you in advanced. OR if you might have a better suggestion as far as a replacement video card? I play games but I don't have to have the graphics turned all the way up, not picky.

  • PSU specs say Power consumption: 120W Recommended Power Supply: 400, so it should be fine. As far as using a 2.0 card in a 3.0 slot

You should probably look at one of these sites which will allow you to best estimate the draw of your system running at idle and full load. As a general rule, the power draw of your system should not exceed 70% of the output of your power supply.

One example is below.
