CMiYC has an important point. There's a lot more to a power supply than simply providing lots of DC current. Tom's Hardware used a constant load. Computers, especially CPUs do not form a constant load. A cpu may increase its consumption by a factor of 10 almost instantaneously. This can happen everytime the scheduler goes from the idle loop to running a cpu intensive task. The motherboard regulation will absorb some of this, but not all. The PSU must be able to respond to these surges without significant ripple or spikes. This requires good capacitors, and may require tuning the switcher frequency to improve the response.
