Upgrading Graphics Card - Is my Case/Mb/PSU compatible?

[Triorchin]

Hi, I'm thinking of upgrading my graphics card to a GTX 1660 SUPER or RTX 2060. I certainly don't want to spend more than £300 to make the upgrade work, happy to go for a different card if there is something better for the money or if an older card would work better with what I currently have. I recently got a Oculus Quest 2 and want a card that will be compatible/work well with that.

Problem is that all the existing parts of my PC are pretty old I don't really know if the card will fit in the case / on the motherboard, or if my current power supply will fit a newer card. It seems that the motherboard has a compatible PCIe x16 slot for the graphics card, but perhaps the psu doesn't have the right x8 pin connector, would there be an adaptor for that or would I need to buy a whole new psu?
I'm assuming that the card should fit in the case, but is there a good way to check?

Any help/advice would be very much appreciated (current specs below).

both case and PSU should be fine.. you just need to measure how much space you have for the GPU and choose accordingly..
both 1660 super and rtx 2060 have smaller version... like PALIT 2060 STORMX etc
