TS-873A: How to add GPU
I have TS-873A and two cards, PH-GTX1050TI-4G and QM2-2P10G1TA.
There is no space to install this GPU with cooling fan.
Besides, this GPU card is PCI-Express card.
TS-873A have two PCI 3.0X4 slots only.
Actually, I have purchased this GPU according to your guide.
How can I solve this space and slot difference issue?
Yes, there is no space for QM2 and GPU card at the same time. Either you choose one or another or use PCIE 4X Extension Cable. Or even connect via NVMe X1 slot (article here).
Even if a GPU card is type X16, Qnap have removed the lock at the end of their X4 PCIe slot so that card could hang over. You do not need to connect all pins (full length) in order for it to work.
Here are few PCI extenders:
PCIE 4X Extension Cable,PCI-Express 3.0 4X Male to Female Riser Cable PCI-E 4X Extender Adapter jumper for Graphics Card（23cm,180°)
PCIE Extension 4X Cable,HONGLEI PCI-Express Male to Female Riser Cable PCI-E 4X Extender for Graphics Card
