Is my H110M-HDS compatible with a GTX 1070 Ti?

Solution
All modern graphics cards use a pcie x16 graphics card slot.
It has been a very long time since pci graphics has been found on a motherboard.

Graphics cards may use pcie 2 or 3 but are both forward and backward compatible with negligible impact on performance.

Some graphics cards had trouble during the transition between legacy bios and uefi bios motherboards.
I do not know the exact details; I doubt they would apply to you.
One thing you could do is to do a google search for H110M-HDS ASRock and the specific make/model of your GTX1070ti.
Most GTX1070ti cards need a 6 and a 8 pin power connector.
Some highly overclocked versions may need more.
Normally, a 550w psu will be about right.
Some Coolermaster models do not deliver advertised...


I will take your word for it, but how do I check for myself in the future if something is compatible. Also I have a 550 Watt power supply from cooler master. Will this do the job?

I would go ahead and try it.
If you have insufficient power, your first symptoms would be display artifacts under heavy graphics load.

You can use a site like https://pcpartpicker.com/ to check for compatibility.

Also, if your motherboard has a PCIe x16 slot and was made sometime in the last few years, it will be compatible with nearly all PCIe GPUs.

Space and power, notwithstanding.

Yes, your PSU should suffice.
