I still have yet to see a proper review of the TX550M. But it should be a good PSU form what I know of it. The GQ650 isn't bad either. What are the prices on those PSUs? I'd just get the cheaper of the TX or GQ.
What are the system specs you are going to use these for, and why only those 3?
my specs are
CPU: ryzen 5 2600x
motherboard: x370 asus prime plus
ram: 16gb kit tridenz 3200
gpu:1070 ti
Hdd: 1tb seagate
ssd: a400 120gb
Chassi: Phanteks eclipse p400 2 fans 1 led strip.
these are the best for the price i could find.
I meant CX650M so its modular
