Deepcool PL550D: ATX v3.1 (almost) PSU at €49!

Overall Performance

The PSU achieves a higher overall performance than the PN550D, which uses a more modern platform (CWT: GPW). Since I only had two 550W PSUs meeting the ATX v3.1 transient response tests in my database, I had to include in the graph several 650W units.

  1. Hi, please tell us how it is “almost” ATX 3.1? This is branded as ATX 3.0 lots of your other reviews also state ATX 3.1 when even the PSU box says ATX 3.1

    Also does this PL550D have a 12V2X6 connector?

  2. Hello. Thank you for the information about this product. Did you measure the hold up time of this PSU under 100% load?
