Thermal master is the brand Cooler master uses in their extremely cheap cases that include a power supply. 16A on the 12v is very low. I wouldn't recommend it.
For comparison the EVGA 430w has 34A on the 12v and the Thermaltake 420w has 35A on the 12v. Your power supply is realistically 250-300w. You might be able to run a GTX750 though.
