Is it Antec that needs to correct issues?
Or does the tom`s hardware people just have no clue?

POWER SUPPLIES UNDER FULL LOAD
Our tests in our Munich labs continue and we thought it would be a good idea to recap where we are today. So far, we have tested several units and 8 have failed at least one of our tests.
In our test-platform, we use four active electrical loads. The platform is custom made for us by Bernd Willer, which he calls the PC-NT-TB2. He is a former AMD engineer and now works as a consultant. The electrical loads are manufactured by the German company Statron.
We stress the single power rails of each PSU with one electrical load, +3.3, +5, +12 V1/V2. Each 12V rail is being loaded independently by a separate electrical load. Each electrical load is able to deliver a maximum current of 50Amps @75V. We load the rails never higher as stated on the max combined wattage sticker on the unit. The -12V and +5VSB rails are always loaded with constant 18W (based on ATX-12V-spec), whereas the load is increased an the other rails during the test. We start at a level of 20 percent of the maximum possible wattage and increase the load within 5h20min to 100 percent of the max combined wattage. You can see a picture of the standard-setup on this page
In addition we measure the temperature at the airflow input and output points and at the ATX connector. We also measure the temperature of the ambient air as well as measure the noise of the fan of the unit.
In addition we measure the ripple of the 3.3V and 12V rails during the test in accordance with the latest ATX-specs.
