DeepCool PL550D Non-Modular ATX 3.1 Power Supply

The DeepCool PL550D is a high-performance, budget-conscious 550W power supply unit (PSU) designed to bridge the gap between affordable entry-level components and modern hardware power standards. Boasting an 80 PLUS Bronze certification, this non-modular power supply guarantees a minimum of 85% energy efficiency under typical system loads, keeping power consumption and excess heat production to a minimum.

Engineered for longevity and safety, the unit features a highly reliable double-forward topology on its primary side, backed by DC-to-DC converters for rock-solid stability on the minor voltage rails. It comes fully equipped with a 120mm hydro-bearing fan that dynamically adjusts its speed based on system temperatures, ensuring whisper-quiet cooling during light web browsing and optimal thermal management during intense gaming sessions.

What sets the PL550D apart from traditional budget power supplies is its native support for the modern Intel ATX 3.1 architecture specification. It features an integrated, high-quality 16AWG 12V-2x6 (12VHPWR) PCIe cable, allowing it to safely deliver up to 300W of dedicated, continuous power to modern, demanding graphics cards without requiring messy or unreliable multi-cable adapter dongles. Built to withstand sudden system demands, the PSU is rated to safely absorb transient power excursions up to 200% of its capacity for brief intervals.

With a compact ATX depth of just 140mm, the PL550D easily slides into almost any standard mid-tower or mini-ITX PC chassis. For total peace of mind, the unit is backed by an industry-grade suite of electronic safeguards, including Over Power (OPP), Over Voltage (OVP), Short Circuit (SCP), Over Temperature (OTP), Over Current (OCP), and Under Voltage (UVP) protections, making it the ideal cornerstone for a safe, modern, and cost-efficient PC build.
