Ultra X4 850W Power Supply

Conclusion:

Packaging: The package that the power supply came in was very clearly labeled with what the device was, the specification, and its features.  The power supply and contents were all encased with a thick layer of foam to help prevent damage from shipping and handling.

Installation: The installation of power supply was among one of the easiest and cleanest i have ever done.  Placing the unit in the computer chassis was simple as there were no wires to mess around with, it was a simple put into place and secure it in (with normal screws or the included thumb screws).  Hooking up all the wires was simply attaching wires from the power supply to the device using the appropriate pre-marked wires.

Features: The Ultra X4 series are featured packed with most every feature you would like your power supply to have.

Performance: The Ultra X4 Power Supply power voltages were within +- 1% of the desired voltage.  This is rather good as the ATX Standards require the voltages to be within +- 5% of the desired voltage.  We tested these voltages on startup, idle, load, shutdown.  So overall the power supply had a very solid performance.

Price: The 850W model can be found on the shelves for $250, whereas the 600W is $119.

Pros:

  • Fully Modular
  • Quiet Operation
  • Easy Installation
  • High Efficiency (80 Plus)
  • Lifetime warranty
  • Good user documentation (manual)

Cons:

  • A bit pricey

  1. Uhh… Where is the review? It looks like a few pages must be missing. Wow!

  2. I don’t see the “review”. looks like a fluff marketing piece for the manufacturer.

  3. I wonder how much are you paid to advertise or ‘review’ this absolute horrific product?

  4. “We aren’t paid a dime. The product is not horrible.” So make a real Review, and use proper hardware to test the power suply, before telling every one that de product is good! Felipe – Brazil

    Just remember I’m an idiot, I don’t know what I’m talking about, I can’t spell, and I like to crap where I’m not wanted. Cya later as I wont ever be back.

  5. LOL it never ceases to amaze me the lengths to which the competition will go to discredit us. Next time use an IP other than the one your website comes from. Oh and by the way I don’t see any reviews on your site using an Oscilloscope and $10,000 worth of equipment to test either. Go take a thread crap on another site. Have fun with yourself at CES and Computex? Oh that’s right you don’t cover major events.
