Package Contents, Fan, and Power Rating

The contents of the package are not very generous this time. Besides a relatively short user manual, two different power cords, and some screws, XFX delivered the modular cables without any bag or cable ties. Of course the electronics is much more important, but customers should get more for the high price. Features of the product include the 80 Plus Platinum certificate, a 5-year warranty, the "EasyRail Technology" (single +12V output) and the "SolidLink Technology". The last item is a nearly wireless connection to the modular PCB. In addition XFX says that this PSU is ready for the most pretentious gamer PCs with CrossFire certification, but that's hardly surprising given the wattage and efficiency rating.

According to the label this PSU has a single +12V output rated at 83A, which is quite a lot. Both +3.3V and +5V get fed by this output and are specified at 25A each. Those outputs can provide up to 125W, which is as high as the values we saw from Seasonic and more than sufficient for all modern PCs, though older PCs might need more power here. The +5VSB at 3A is also relatively strong.

The Protechnic MGA13512YF-025 is a good fan with a fluid dynamic bearing (FDB is a kind of long-life version of the sleeve bearing), but we'd like to see Sanyo Denki here. In this case the fan is sharp-edged and more audible than the San Ace one. XFX could get Sanyo Denki without any problems since Seasonic uses them as well. However, this version is still better than the quality Yate Loon or equivalent that other companies use. The fan is the only moving part in a PSU so it's nice to see that XFX chose a FDB.

    Why isn't there any mention of what the input voltage is?
    I assume you're testing in 120V but i'm quite sure a large percentage of your readers are coming from somewhere with a voltage more around 230V.

    Please, how does this affect the efficiency? Surely there's some way you can get a power supply that can provide these tests with both 120V and 230V tests?

    ~220v inputs generally make for more efficient PSUs, though ripple will often increase by around 16% to account for the variance of 50 vs 60hz commonly used in 220v-based countries like the UK.

    230v. :)

    -6% to +10%

    You can see in the picture on the second page that a European plug is included, so I assume it supports 230/220V.

    "for the difference ($17 USD) customers get a better fan and a few extras such as cable ties and a bag for the unused cables"

    The fan difference my be important important. Also, and it's not mentioned in the review, Seasonic offers 7(!!) years waranty versus XFX's 5.

    You're right.
    Warranty has been added..

    The last high end PSU I've bought was an Antec Signature 850W a few years back. I believe it cost nearly $300, and there was NOTHING on the market that approached its quality at the time.

    It's nice to see there are a lot of new units coming out that are giving great power quality with even higher efficiency at much lower prices.

    Hopefully the quality/pricing continues to trickle down to <500W power supplies.

    "option to have the CPU run passively has <40% load is a nice feature if you don't need the airflow a PSU can provide"

    Having a CPU run passively (without external power) would be nice indeed ;-)

    This makes it sound like 80% is the minimum efficiency for the Platinum certification.

    This PSU only makes Platinum certification with 0.56% room to spare at 20% load, so I'd hardly say it "easily" makes it. Not that it matters, because the efficiency is still astounding.

    80 Plus Platinum requirements at 115v:

    20% load - 90% efficiency
    50% load - 92% efficiency
    100% load - 89% efficiency
