Summary:
It's a relatively modern motherboard and chipset, the slot type is backward compatible, just make sure it has adequate power.

Details:
If the card recommends 400W, I wouldn't mess with that. It will need 400W.

For 300W, at best you'll get it to boot up, but it will crash and lock up for no apparent reasons. At worst, it won't boot.

Yes, PCIe 3.0 IS backwards compatible, it's not just a theory.

As another poster mentioned, boot in safe mode, uninstall the old driver, and delete the drivers.

Place the new card in, with an adequate power supply.

If there are auxiliary power ports on the video card, make sure they are supplied with the extra power they need as well.

Power it up, the system should detect the card, and if it doesn't have drivers you will need to manually select from the install disk.

One problem I had when installing a recent video card was the hardware ID of my card was not in the approved list of drivers, so it would not appear for me to even be able to manually install. I had to modify the driver's INF file and perform some other wizardry. If it comes to that though, check back.

Finally, a bios update is always a possibility, however, I have only ever had to resort to a bios update if I found instabilities in my machine, and the bios update indicated that it might fix the issue.

The bios update is the LAST thing I would attempt.

Regards,
Paul
