The PSU design itself is OK, it's the parts that are not adequate for its rating, but after doing my modifications, it can deliver its full 300W and can short it without breaking anything. It was built down to cost but as a basic bench PSU, it's fine as long you know its limitations (there are many). In stock form, I wouldn't run the supply or any of its variants over 150W continuous.
