    Analysis of Results

    Wow. There's a lot to digest back there. Let's start with the 500W power supply.

    The 500W X-Finity held it's 12V rails well, even under significant stress. Going from a 192W load on the combined 12V rails to a whopping 384W, the 12V only dropped an average of a mere one quarter of a volt. The crossload test shot the 12V up to an unusually high number. This is what we typically see with crossloaded ATX12V power supplies. It is within spec, and the numbers did not "dance" like some previous power supplies I had crossloaded.

    The efficiency was AMAZING. Typically 70% or better is your average power supply. This puppy maintained 75% efficiency even under 100% load! The low load, which is the most realistic for a PC at work, was an amazing 80%. This brings me to the new fan Ultra is using... it was VERY QUIET.

    When a power supply is more efficient, it generates less heat and therefore needs less cooling. Even under 100% load, the RPM's of the fan was minimal. I was really impressed.

    The 500W has it's 115/230V input selecter on the INSIDE of the case.

    The 600W has a very traditional look by today's standards, but houses a lot of power.

    The 600W took a beating. There was only a .15V drop going from 240W to 420W. There was only a .1V drop during the first three tests. The crossload test went much better for the 600W unit. The rails held very tight despite the 159.4W load on the 3.3V+5V combined rails.

    Efficiency was just average with the 600W unit. It maintained a typical > 70% efficiency, except for when all of the rails were cranked up to 100% when the efficiency dropped to an ugly 69%.
