I would email your motherboard tech support to be safe. You need to list your board make and model number; same for the power supply.

here is the link to all of the specs for my computer...

It should work if your power supply has at least one pci-e connector; most are 6 pin; check your card to see if it uses a 6 or 8 pin connector from the power supply. I recommend a new antec or corsair 500 watt ps. Also take a tape measure and get the length from the ports on the back to the hardrive cage to be sure your card will fit. The HIS brand I checked takes an 8 pin connector.

That system's power supply (300w) will not meet the needs of the HD7970. To use this GPU, the OP will need a stronger PSU as well.
