Don't be fooled by the fancy sounding name on that card, it is as bottom of the barrel as you can get performance-wise. It isn't anything more than a G210 with a fancy name,
Not to mention it uses the PCI-e X1 slot.
Also while trying to find some specs on your motherboard I saw where it says it actually has a 220w power supply and not a 250w.

220W
220w power supply (100v-240)
Sorry to say your pretty much stuck with what you have.
Theirs a lesson to be learned here and not an easy one to swallow, but whenever buying from an OEM and you have thoughts of possibly upgrading in the future make sure you have looked thoroughly at all the specs to see if upgrading is even possible.
Might help others in the future. Fabe
