    Worse fan though...

    It's not a clean sweep for extra $25.

    Advantages of AXi, while do exist, are rather minor and probably not noticeable in real world operation.

    I wouldn't pay up for AXi.

    Stupid decision imo, the HX650i would be perfect with to GTX 970's or GTX 980's.

    If you knew the behind the scenes, you wouldn't say it was a stupid decision. The BOM was all of $1.25 difference between making a 650W and 750W on the same platform. Making or using a whole different, cheaper platform for the lower wattages is feasible and lowers per unit cost (though not significantly. Maybe $5?), but would double the NRE costs for the project and cause significant delay.

    Getting fancy with the fonts, are we?

    Thanks so much for showing us the BOM cost difference. Since the difference in electricity costs so little (in the US at least) the only remaining reason to go with a 750W rather than a 650W would be the amount of noise it makes in the range where we normally use the thing.

    Personally I would be a tad surprised whether an HX650i generated any noticeable amount of less noise over an HX750i.

    On the other hand, "in the range where we normally use the thing", I would be glad to see an high quality unit (like an AXe or HXi) with a decent efficiency (> 77%) starting from 15W DC (but maybe there is some technological/topological reason behind the fact that actually there is no such a unit, nowadays).

    Thanks all for your replies,
    I think I'll go for the HXi as just because of the price difference. And as people have said, the HXi is still a good power supply.
    Thanks again!

    There's a review of each of them on this site:

    AX860i: http://www.jonnyguru.com/modules.php...Story&reid=317

    HX750i: http://www.jonnyguru.com/modules.php...Story&reid=392

    Yeah, they're 110W apart, but the AX760i and 860i are the same platform and HX650i, 750i and 850i are all the same platform.

    Thanks, i'll go for that AXi
