    I think they'd be great for a digital audio workstation environment now if only there was some more competition in this market segment to drive prices down to a more decent level.

    "The +12V CPU connection is only available as 4-pin version, which can lead to problems with some boards that require an 8-pin connection."

    Know of many HTPC boards that need an 8-pin CPU connection? :\ I sure don't.

  • I have read 3-4 other reviews of the zen 400W, and I'm pretty sure there has been no mention of the high pitched sound. It's not a good sign for the zen, but it's probably a faulty powersupply tested in this review.

    Ummmm, so where's the temps? The review is practically pointless without temp measurements on a fanless PSU. BOOOOO!

    Without specifying the input voltage, efficiency measurements are pretty useless. Running at 240v will yield a few percent higher efficiency than 120. Even 240v will be more efficient than 220v.

    Re-run your review and include tempratures. Its pointless w/o them.

    If you have found a fanless PSU thats safe to touch -- thats great. but if these things get to 40, 50, 60c - then we need to know not to buy them.

  • I own the Zen400 power supply and it's exactly what I needed for a quiet HTPC, to the point where it's literally impossible to tell when the PC is on. During normal operation I have never heard the high pitched sound this review mentions (although it did output a sound similar in volume and annoyance to a smoke alarm when I failed to plug in the power cable to the graphics card - it was clearly an error/failure tone).

  • In regards to the lack of the 8 pin CPU 12v connector, if you can find a motherboard of which the 4 +12v pins of the port are not electrically connected, please point it out to actually justify needing the 8 pin connector. To be honest, a motherboard with a single +12v pin isolated to only 1 or 2 vcore phases would'nt be any motherboard you would want to purchase, for power efficiency reasons.

    I agree with the above posters, temps would be nice, and not just of the PSU...

    I am quite interested in getting a capable (above 400watt) PSU that doesn't require a fan, but I really need to keep an eye on the temperatures.

    I have a fanless mb and vid card (3850 radeon), and would wonder if adding a fanless psu into the mix would jeopardise the system by reducing the air flow through the case. (after all I wouldn't get a fanless PSU if my other components were noisy to begin with!?)

    Perhaps an article focused more on configuring a quiet computer (for the purpose of gaming) could be in order?
