Power supply squishes into ATX connector

Feb 17, 2009 — by Rick Lehrbaum — 86 views

While attending the Real-time and Embedded Computing Conference in Silicon Valley last month, we spotted this tiny ATX power supply implemented in the form of an ATX power connector.

Sparkle Power’s teeny-weeny 65 Watt power supply converts +19V DC input into the full complement of ATX voltages. Key specs for the tiny ATX power supply (P/N SPD065EP19U1) include:

  • Input voltage — 19V DC
  • Input current — 4.0A maximum
  • Output voltage individual ratings:
    • +3.3V @ 7A

    • +5V @ 7A
    • +12V @ 4A
    • +5VSB @ 1A
    • -12V @ 0.1A
  • Total output power — 65W maximum
  • Supports software-controlled on/off function
  • Supports power good signal function
  • Provides over-voltage and over-current protection
  • Operating temperature — 0 to 50 degrees C
  • Storage temperature — -20 to +80 degrees C
  • Dimensions — 1.8 x 0.9 x 1.7 inches

Here are a few photos of this nifty little ATX power supply:

Sparkle Power supplies the SPD065EP19U1 along with an external AC-to-DC power adapter module, most likely one of those shown on this page of the company’s website.
