    Default [TechPowerup] Enermax Platimax 850W Review

    The new Platimax series is based on a fine tuned Maxrevo platform with optimizations for the strict 80 PLUS Platinum requirements. At this time, the Platimax line has four members available with capacities ranging from 750W to 1200W. The two stronger units, with 1200W and 1050W utilize a fully modular cabling design while the 850W and 750W ones are semi-modular. Two more units with 600W and 500W capacity will be added to the Platimax series in the future, to cover all user needs. All Platimax units are equipped with twister-bearing fans, use Japanese caps and feature the dynamic hybrid transformer technology. Also Enermax backs them with a five year warranty and claims that they are able to work 24/7 at 50°C. We will see about that in our tests, since we plan to crank up the heat inside the hot box.

    The regulation on the +12V rail is better, but overall, it still sucks big time.

    I'm really disappointed by these Platypus units.

    Looks like soldering went down hill a bit as well. Though, the performance is pretty much expected.

    Why does the +3.3v regulation still approach ATX specification? Platimax looks like a big no-no.

    personally I think that they focused too much in efficiency (although at 20% load is still below platinum level) and left for last v. reg.

    This platform is very good and has lots of potential. It just needs some more tuning.

    Same old DHT platform, with some improvement in secondary SR and first-stage filter. The soldering job was actually improved (except the hand-made part), both on the solder side of main board and modular connector board, where hot air solder leveling is used, a welcome improvement over earlier Revolution85+ and Modu87+.
    It's been a hard day's night and I've been working like a dog.

    Enermax's soldering quality improvement. Left: Modu87+. Right: Modu87+ ErP Lot 6 (newer revision with improved standby efficiency and better looks).

    looks like Enermax use single layer PCB on module panel for Patimax the top model, the single layer is unreliable for module panel and it's very possible have some soldering issue after plug and unplug, it's necessary to upgrade the PCB with double layer and through hole for module panel
