I recommend you to buy a PSU from 170W to 230W even more because you will have an i9 + T1000 in you setup.Actually my M920x Tiny came with a 135W power supply, so theoretically it should be enough for the i9-9900T (35w) and T1000 (50w).
To comparison I got a T340 with i9 10900 (without dGPU) and my 130W PSU doesn't work well. It starts to emit some pops and noises that clearly indicate that a PSU is not supporting my setup.
Future I'm gonna buy or a 170W or a 230W because this T340 will have an SFP+ NIC.
