For a value unit, the performance of the VX450W is remarkably good. The lines are very stable overall and do not ever fall outside their specifications. The regulation of the lines is quite tight and they stay steady enough when large load changes take place. While the unit works perfectly fine at 450W capacity, it will shut down within a few seconds if the load surpasses 460W even if it is cool at the time. We’d like to think that this particular unit is capable of more, but at least we know that the overload protection circuit of the unit works fine.
