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

Box & Bundle

The box is plain, but it does its job well in protecting the PSU effectively. Once you open it, you will be greeted by the paperwork.

This is the typical DeepCool PSU design, with the weird-looking fan grille with large openings allowing for good airflow. The PSU’s dimensions are compact, thanks to the 140mm length. At its front size, the exhaust grille has rectangle perforations instead of the typical honeycomb-style ones, and the power switch has a distinctive color.

Around the back, the flat native cables leave the PSU from a relatively small hole. The hole doesn’t have a plastic grommet, but its edges are rounded and not sharp, so they won’t damage the cables.

Cables

Captive Cables
Description Cable Count Connector Count (Total) Gauge In Cable Capacitors
ATX connector 20+4 pin (560mm) 1 1 18-22AWG No
4+4 pin EPS12V (735mm+145mm) 1 2 18AWG No
6+2 pin PCIe (580mm+120mm) 1 2 18AWG No
6+2 pin PCIe (580mm) 1 1 18AWG No
12+2 pin PCIe (590mm) (600W) 1 1 16-26AWG No
SATA (440mm+105mm+105mm) / 4-pin Molex (+100mm) 2 6 / 2 18AWG No
Modular Cables
AC Power Cord (1395mm) – C13 coupler 1 1 18AWG

The number of cables and connectors is sufficient for the PSU’s capacity. The EPS cable is extra long, and the ATX cable is long enough for a low-capacity PSU, which will be primarily housed in small and medium-sized chassis. The 12+2 pin PCIe cable is set at 600W, which is insane given that the PSU’s max power is 550W. According to Intel’s guidelines, it should be set at 300W. Lastly, the distance between the peripheral connectors is short at 105mm, probably because each of the respective cables has five connectors, so the voltage drops on the last connectors would be increased with a longer distance.
