I am going to buy gt 1030, but i am little worried about will my mercury pih61t motherboard support 1030 gpu?
Yes, your board will work fine with the GT1030 as long as it will fit in your case.
It requires two back slot spaces and will fit into your PCIe x16 slot but cover the PCIe x1 next to that slot. You will also want to check on how much room you have for the card length and which version 1030 you buy. It is either 6.68 or 5.4 inches in length depending on the specific model.
It does not require an additional power connector so no problem there.
