NZXT E-Series PSUs give builders power over their power

NZXT is launching a new range of power supplies this morning to give system builders a window into the operation of their PSUs. The E Series starts with Seasonic's well-reputed Focus Plus Gold PSU platform. NZXT adds a Texas Instruments DSP and USB connectivity to the package in order to allow for monitoring of the 12 V, 3.3 V, and 5 V rails through the company's CAM software.

The E Series PSU family further offers digital over-current protection on all three of its 12-V outputs, and the threshold for that protection can be adjusted on the EPS and PCI Express connectors. Thanks to its Seasonic platform, the E Series boasts 105° C-rated Japanese capacitors, an 80 Plus Gold efficiency rating, and a fully modular design. All E Series PSUs will offer a semi-passive mode and three prebaked fan profiles, plus a customizable fan curve. The CAM utility controls all of these fan settings.

NZXT will offer the E Series in three sizes to start: 500 W, 650 W, and 850 W. The E500 will sticker at $124.99, the E650 will run $139.99, and the E850 will list for $149.99. NZXT says all three models will be available from its website today in the United States, while the rest of the world will be able to plug in these power supplies in late July.

    I just want my PSU to work reliably and efficiently with little/no fan noise. What do I need all these extra frills for?

      But don’t you want to be able to manage it from an app on your phone?? Surely that’s worth a small subscription for the IoT cloud service that makes it all possible!

      I’m sure next year these will swap the USB connection for an 802.11b radio to enable just such a thing.

    I’m not impressed with the fan grill. You don’t see many punched hole grills these days since manufacturers started using honeycomb grill patterns that have much better airflow properties. Not sure why they went backwards in this design.

    Good news is that most people don’t use anywhere near to the max capacities of their PSUs so it likely doesn’t need a whole lot of airflow. But if it does, this thing is going to be louder then other PSUs.

      When the designer outranks the engineers, you get this. See also: [url=https://en.wikipedia.org/wiki/NetBurst_(microarchitecture)<]Netburst[/url<]

    [b<]The good news:[/b<] NZXT typically use a Seasonic design that is known to perform flawlessly. [b<]The bad news:[/b<] NZXT supplies are probably ASSEMBLED elsewhere outside Seasonic, and unlike dozens of other units using identical, flawless Seasonic platforms, these have quality control issues (solder blobs, poor component trimming etc) that is unique to NZXT at the moment. This results is barely-within-spec ripple when hot-tested. [url=http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=297<]JonnyGuru's tested three of their latest PSUs now, and all suffer the same QC and ripple issues under hot testing[/url<]. This puts unnecessary strain on your motherboard and GPU PWM filtering, and cannot possibly be recommended when there are PSUs from the competition that perform almost perfectly.

      I don’t have definitive information about the sourcing of these PSUs, but I would caution that “latest” in this case refers to a review of a discontinued product from 2012. It might be worth waiting for a fresh round of reviews before writing these off.

        True, its been a while since they made PSUs.

        Perhaps realising that the profit margins were too thin and that shaving assembly costs wasn’t working for their review scores they left the market.

        Corsair are doing very well with Great Wall as an OEM, in their TX series. I buy a lot of those because they’re affordable and excellent. I only mention it because last time for NZXT Seasonic was the ODM not the OEM, and that meant that the all-critical build quality was a cut corner that is the ONE THING that PSU buyers don’t want to skimp on. I can only hope they’ve learnt from their mistakes, since I like NZXT as a company – they’ve done good things for cases and AIO cooling, enough that I’ve put my own money (not company money) where my mouth is.

        NZXT cases: good.

        But their components have been pretty hit or miss. IIRC there have been at least [url=https://www.youtube.com/watch?v=OkmQw0gnpzQ<]one[/url<] or [url=https://www.youtube.com/watch?v=WEXSafHSYbU<]two[/url<] youtubers who built systems using NZXT's Z370 motherboard and hated it.

      Hey Chrispy!

      Good news – Our new E Series are 100% made by Seasonic in-house. So expect the same quality as their Focus Gold platform, of which the E series is based on.

        Nice!
