Hands On: iStarUSA XEAL IS-500R8P 500W PS2 Mini Redundant Power Supply

The Verdict

I do not have the equipment or apparatus necessary to stress test a power supply unit.  As such, I cannot provide a “performance” section.  What I can say is:

  • If you need a redundant power supply, here is one choice.
  • From past experience with other iStarUSA products, they build industrial-quality products, so you should be able to expect their products to last and perform well.
  • Make sure you locate the computer in an area where noise will not be a problem.  Those fans in these modules are not silent.
  • While this should be obvious, it is still best to state that iStarUSA does sell the individual power modules separately in case one does die on you.
  • This units are designed for rackmount cases, partially due to the length of the unit and partially due the special IPC mounting plate that is needed, which you find mostly only with rackmount cases.

This leads me to the one question I always answer last: how much does this item cost?  As you might guess, a redundant power supply unit is going cost more than your typical ATX power supply.  At Newegg, this particular item will set you back $474.99, which is $25 off the normal price.

Hello. I’m from the heartland of the U.S. Lots of corn and beans, although Iowa is a lot more than just farmland. It also has a few computer enthusiasts (no, not me!). I’ve been around PCs since I got my 1st PC XT aloooong time ago. WGS is one of the first sites I found centered around WHS. And the best. Every once in awhile, I do get away from the KB and enjoy time with and my wife and our 4 kids. And I do have a day job.

    Jim,
    Good article on an interesting piece of hardware. Thanks for the clear pictures.

    The drawback of redundant power supplies for the home, SOHO and SMB markets is the single point of failure is transferred to the electrical circuit feeding the power supplies. Ideally, each power supply should be on a separate circuit which can be difficult to impossible to implement in a small environment.
