Cases & PSU/Power Supplies by piotke @ 2006-02-14

I sometimes repair computers for relatives. Most of them have pre build computers, such as Compaq, Packard Bell ... When the PSU fails it?s very difficult to find one that fits those special designed cases. Seasonic has a solution for that. The Seasonic Super Versatile 250W PSU should fit in most of the cases. Let?s find out if it is a worthy replacement ? we test performance and noise level.

Introduction & Installation


Today we'll be testing a Small Form factor Power Supply. Seasonic was so kind to send us their newly introduced SS-250SVP Active PFC, a 250-watt mini power supply. There is another model Super Versatile 200, rated at 200-watt.

Seasonic you say? Seasonic has been in the business for over 30 years, a veteran in power supply manufacturing serving the OEM markets. Its channel of distribution expanded to mass market a few years ago using its own brand name allowing the PC enthusiasts the same quality products once enjoyed only by OEMs. . Here is a little history overview from their site:

  • 1975 - Sea Sonic incorporates to manufacture Electronics Test Equipment.

  • Impressive history, I may add. While Seasonic is new to me, it is certainly not for other MAD reviewers, we have had tasted their excellent S-12 500 in the past; and their Power Angel just a few days ago.


  • Active Power Factor Correction (99% PFC)
  • Super High Efficiency (up to 80%): Save 15% more energy than regular Power Supply.
  • Smart & Silent Fan Control: Reduce noise without increasing temperature, silent enthusiast’s best choice.
  • Full three years warranty
  • All-in-one Bracket: Upgrade or replace your brand name PC’s power supply. (e-Machine, HP& Compaq)

  • The last item certainly sounds interesting, as this might replace the aging power supply in an older computer, which may otherwise cost a lot more from the friendly OEM hard part department.

    Let's take a look at the package and the unit itself. In the box we found:

  • SS-250SVP
  • Power cable
  • Screws
  • Short manual
  • Dr. Cable and cable tie for cable management

    For 250-watt unit, this power supply packs quit a lot of connectors. Except for the normal ATX connections (20 and 4 pins) there are four (4) molex connectors, two (2) SATA and two (2) floppy drive connections. The last connection is a fan header with two leads for monitoring the fan speed in the power supply.

    Size wise this unit is dwarfed by a conventional ATX power supply; in the photo’s below you can see it compared to a Zalman PSU.

    The installation is plain and simple, but there are some extra's that need to be addressed. First the back plate which makes the PSU multifunctional in either a small or large case: Secondly, the Dr. Cable to wrap over the main and 4-pin cables or however neat the user likes to make it in optimizing case airflow.

    Dr. Cable comes in two sizes; a large one for the main and the smaller for SATA, Molex and however the user sees fit to work on. For the finishing touch there are tie wraps provided.
