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.

    We cannot run after every brand there is and if those companies don't come to us... there are surely many more missing but we can only test products from companies that are actually interested in us testing their stuff. We had an Akasa unit before though... Reply

    I guess that is the problem with almost all review sites. And the worst thing is not that you skip the smaller guys, but that what you are reviewing is not off the shelf, it's sent to you buy a company that wants a good review. So even if they have rotten quality control, and half their stuff is DOA, you know the one they send you has been triple checked and fine tuned. Not your fault, but to me the reliability is MUCH more important than a few extra watts or a few less decibels, and there's just no way to get good data on that.

    If you read the reviews here, you'd know that this assumption is false in general. AT has had junk on their bench on more than one occassion - if every supplier would do what you claim, all reviews would take place in happy bunny land where everything is dandy and no negative notion is possible. But thats not the case.

    Surely there will be those who go the extra mile to make their product look better than it is off the shelf, but you just cant hide every trace of incompetence and bad quality.

    Much like we cant expect a review site buy every piece of hardware to test it and hope they can re-sell it without a loss.

    I'm just curious why the "old" version of the Antec Earthwatts 430 was dug out and retested since Seasonic is no longer the OEM for it but now has Delta as the OEM supplier and has been for many months now.

    Seems it'd be only fitting that the "new" version would be tested instead of a version no longer being made or sold, except as NOS (new old stock).

    If only "someone" could send it to us :] I will make sure to get new revision on time, you're totally right. Reply

    What were those bad things happening to the SII Seasonic PS? Reply
  • JarredWalton - Wednesday, December 31, 2008 - link

    I believe Christoph is just saying that he's received an increase number of email messages from people saying that their Seasonic PSUs have failed. It's anecdotal at best, and it could just be a case of more people buying their PSUs and thus a small fraction that fails can still result in more complaints than before. Reply

    Yes ;)
    There was a revision in the beginning that had problems with certain motherboards somehow, something to do with the "power good" signal. They've upgraded the series long time ago though.

    I'd just ordered some new parts, including a CX400 about 30 minutes before I saw this article come up.
    Nice to see that my choice seems fairly solid.

    I'm sure this article will be relevant for other people as well.
