OCZ ModXStream Pro 400W

The latest addition to OCZ's power supply lineup is the ModXStream Pro series. The 400W version we are testing today is made by CWT while the other power supplies in this series are made by Sirtec. The ModXStream comes with cable management as the name suggests. The housing and the fan grille are black and the back is well ventilated to exhaust air. There are two 12V rails, one with 17A and the second with 14A.

It's a somewhat odd decision by OCZ to let different manufacturers produce their different power supply lines, and now we even have different manufacturers producing models within the same series. Maybe Corsair started this trend by changing to CWT for their higher wattages options (instead of Seasonic), but what OCZ has done here is barely understandable. OCC is currently utilizing FSP, CWT, Seasonic, Sirtec, and Impervio. However, even if the decision is odd it's not a serious concern, since most of these vendors produce high quality products. The inside looks similar to the HEC-350TE-2WX with minor changes to the housing and components. All of the capacitors are made by SamXon and the fan is made by Yate Loon.

The OCZ ModXStream Pro comes with two cable harnesses each with three Molex connectors, and another harness with four SATA connectors. The 24-pin, 4-pin and 6/8-pin PEG connector are 50cm away from the power supply. All cables are of course sleeved.

    That is a heck of a lot of work for this article and we appreciate it immensely! Between this article and the upcoming mid-range builders guide (I'm begging...please get it out asap) you have reaffirmed for me this is the #1 site.

    Thanks again.

    The breakdown of the cable connectors and the build quality descriptions were helpful. The power noise charts look useful as well. Reply

    Copy that, one of the best PSU roundups around. Reply

    We definitely appreciate the roundup. It addresses our needs as consumers. I wish you'd add more info about the Antec Earthwatts 430 though... it's one of the most popular PSUs on the forums here and always shows up for cheap in the hot deals section, often bundled with an Antec case. Wish you'd give us more details on its efficiency, ripple, and your overall take. I don't think you actually said anything about its performance at all. Thanks! Reply

    Isn't there a Delta made version of the 430 as well? Reply

    Yes which we didn't have. Reply

    Here's the original review from a year ago. Even though I didn't mention it in the conclusion I think you have a great comparison with the respective graphics towards the end. :)

    Thanks for this article. I am one of those who does modest OCing and no SLI, and this article was pertinent for me. Reply

    No temperatures at load? I would think that temps at 100% load for each unit shouldn't be too much. Just as a worst-case thing. Reply
