    Damn, and I though that only Arctic Cooling is capable to nerf a Seasonic S12II.
    Thanks jonny, I was anxious to read a 450W review but so disappointed after reading...

    Facepalm worthy indeed. All it would take is a peek through the fan grille to see there are no VRMs in there. Don't know what's up with the XFX marketing department.

    False advertising? Or were they just lazy, editing the box?

    Still pretty funky results.

    I know. I had read a review of the unit on another site a couple weeks ago and realized it was an S12II. I just thought it was fun to "pretend" I didn't know for a couple pages.

    False advertising, maybe? I don't know, but the box for the SS12II based 450W and 550W is completely different from the box for the 650W and up. These boxes have more protection for the power supply and less real estate for marketing bull shit.

    During test 7, I actually said "holy crap, that's loud." Despite the noise of the loud noises of the SunMoon load tester, I could hear the 120mm fan of the XFX Core Edition 450W spin up and become quite audible.

    Still, looks to be another budget contender.

    That +12V regulation.... Huh???????

    Sorry, with those numbers I just can't recommend it vs. the NeoECO 400C that's still on Newegg. I'll be really sad if Antec ever discontinues that unit, because right now it's carrying the flag for cheap-but-high-quality 400W units. I've heard mumbling that it isn't very profitable though.

    Ooo-ooh,

    I guess on this unit the +5V voltage is regulated more while the +12V voltage is only loosely regulated. In Jonny's test the minor rails are loaded pretty heavily. Under full load the +12V rail takes up only 72% of the total load, so in order to regulate mostly the +5V voltage, the PWM controller increases the duty cycle with load, which also increases the +12V voltage with load.
    It's been a hard day's night and I've been working like a dog.

    Exactly. But what made them think they had to do that? We've reviewed the S12II before and voltage regulation was not an issue. At the very least, they could have programmed the PWM controller to not increase the duty cycle as much as they did.

    Ouch. That's just painful.

    It does seem like the design is bugged in some way; maybe they just had a bad batch of programmed chips?
