    Default Rosewill Hercules 1600W @ TechPowerUp

    The Hercules-1600 is not only one of the strongest PSUs on the market, but its length of 243 mm also makes it one of the largest! Only a few cases can accommodate it, which isn't much of a problem since the system it powers will require a large case as well. The Hercules has two +12V rails with unequal power distribution. The first can deliver up to 110 A while the second feeds two EPS connectors and can deliver up to 50 A of power, a sufficient amount for every CPU(s) regardless of its overclock and power consumption. You also have at your disposal sixteen PCIe connectors for your VGAs. However, a problem arises if you have enough money to buy four VGAs as you will still need a special motherboard to install all of them, and even installing four high-end VGAs will leave you with spare PCIe connectors for future upgrades. As you will have noticed by now, everything about this unit is over the top, including its price of $400! But such a price will not intimidate you if you have the right system for such a PSU.

    Amazingly quiet unit if nothing was wrong. Decent performance overall. I still like the Maxrevo 1500w a little more. But here comes definitely a competitor. Price needs to drop somehow.

    -edit-
    OK. SuperNOVA NEX1500 Classified is more friendly with its current price.

    But there seems to be something wrong with this unit. I don't think it can be sold with that power factor.

    110A on the 12V1 rail? I really do think it could have been split up a bit more than that.

    Those PF readings are as low as I've ever heard of for an APFC unit. That's what I would expect from PPFC (Not that it matters here, though. We only get charged for real wattage). I would be interested to see if someone in the US/Canada could test it on 115V to see what the power factor would do there.
    No wonder it doesn't work! You installed the coils backwards

    Yeah. There is something weird about that PF. It hearkens back to a time where PSUs confused Kill-A-Watt meters! It can't be that low... can it?

    How's the Earth grounding in this thing? I wonder if the PFC/PWM IC is getting proper ground.

    80 Plus Silver requires 0.9 PF at 50% load - those numbers fail.

    That's not on 230vAC though, only 115vAC.

    As for this unit, it's pretty obvious it costs far too much to make for what it does performance wise.

    ToughpowerXT 1475w, SuperNova 1500w, & Lepa G1600 are all better values and equal or greater performers depending on the category in question.

    PF on 115Vac must be even lower.

    Actually, no. Not if at 115VAC, the current and voltage waveforms are closer in sync than they are at 230VAC and therefore easier for the PFC controller to correct. I'm just surprised that at 230VAC results are THIS BAD. I mean, this is the same IC as the Corsair CX, GS, etc. and I've never seen this big of a difference between 115VAC and 230VAC PF numbers. So it's either a bad unit or Sirfa missed something in the design.

    A THD measurement might tell us more; if the PFC is working poorly, or just not working. The WT210 measures THD, I believe.
