    You'll note he listed specific models. One of which (X3) will outperform just about every other PSU in its class I've ever seen.

    I have never even heard of it. Getting old is a ...

    Any good reviews?

    EDIT:
    Ultra X-Pro/X-Finity/X3 600W APFC (not non-APFC) and 700W APFC
    Maybe I'm blind, but I can't find the X-Pro or X3 on the Ultra website.

    Yeah they don't have it there, it looks like they're still in development from some posts on their forum.

    The X-Pro is very close to release. It's a pretty stout little monster too. Personally I wouldn't put the Toughpowers as a tier three, I'd consider them tier two based off their voltage stability and features.

    They're currently working on packaging and are just shipping review samples right now. But let's put it this way....

    You have a dual layer PCB, with quality components, Teapo caps, a huge 5" x 5" heatsink across the top, 130MM fan, 80-85% efficient with 84% efficiency typical and APFC from a "trusted" OEM, almost no ripple.... I surprised myself when I didn't put it in tier 1.

    Madmat has one and, not to pressure the poor guy, maybe he could write up a review of it. At least maybe he could chime in with his experience.

    I wasn't sure about the NDA so I was being vague...So far it's looking fantastic. There's just a .18V drop on 12V1 going from a 96W to 580W load, 12V2 is a bit more drastic at .20V ( ) while 5V drops just .09V and the 3.3V rail sags a mere .13V.

    Baseline voltages are 3.33V @ 3.33, 5.0V @ 4.98V 12V1 @ 12.33V and 12V2 @ 12.32V. Those are the voltages @ 96W load so you can extrapolate from there.

    That's going from respective loads of 2.00A on both 12V rails, 5.00A on the 5V rail and 2.0A on the 3.3V rail to 18A on both 12V rails 17A on the 5V rail and 14A on the 3.3V rail.

    I'm impressed as you can imagine. As soon as I get a camera to work with (the one I was using met with a very unfotunate fate) I will have a full review up.

    I didn't sign an NDA. Did you sign an NDA? I didn't sign an NDA.

    The .2V drop on 12V2 surprises me. I didn't see that much of a drop. Then again, you're also getting different voltages off the ATX and 8-pin connectors when you really shouldn't see more than a .01V difference between the two. So there must be some resistance there somewhere (crooked pin, etc.)

    I need to dig out my trusty DMM and take my measurements from the PSU, this'll take any losses from resistance out of the equation.

    There's contacts for DMM probing on the front panel of the load tester too.

    Yeah but I'm wanting to take the actual physical interface between the load tester and the PSU out of the picture. This'll tell me where the fault lies and I can adjust the load on the tester to where it's actually pulling the same wattage on both rails.

    Yeah, I'm a bit anal.
