Hi,
You can never be safe, but any of the currently available PSUs is likely ok. Your problem is often considered for not enough power and alike in online forums. (My PC does not power up when I use this PSU, but it does power up with another PSU. Then most people say not enough power :-) )
Look for any PSU with the info ATX12V 2.31 or ATX12V 2.4. This indicates, that its PG signal is according to the latest revision, which means it is for the latest MBUs. (But still incompatibilities can happen.) Your TPQ-1200 is likely ATX12V 2.2 designed.
Next time you buy a high-end MBU, wait 2 weeks after launch and check the MBU makers support forum for complaints about not starting up problems.Especially for next-gen CPU MBUs like "X99". Wait and let others buy first. Always good to be not the first buyer :-)
Just for illustration, below is a PG Signal chart. For example, MBU a cannot stand it if 12V & 5V start at the same time, the next MBU is ok with it, but cannot stand it if 3.3 & 5V start at the same time. They should be ok, but, the reality is, there a million IF-Conditions within the mechanical design and they are not as tolrant to signal variation as they should be.
