DeepCool PL550D-V2 550W 80 Plus Bronze ATX 3.1 Power Supply – R-PL550D-FC0B-US-V2

Embrace the ATX 3.1 Standard for Ultimate Stability

The DeepCool PL550D-V2 represents a significant leap forward in non-modular power supply design, bringing your system into full compliance with Intel’s stringent ATX 3.1 architecture. Built to handle the rigorous demands of modern computing, this 550W powerhouse is engineered to effortlessly manage sudden electrical surges. Thanks to the native ATX 3.1 standard, the PL550D-V2 can safely provide up to twice your total system power for a duration of 0.1 milliseconds. This massive power excursion tolerance guarantees that random power spikes from high-performance processors or graphics cards will never compromise your system stability or cause unexpected shutdowns.

Native PCIe 5.1 Support Out of the Box

Prepare your rig for the future without the hassle of bulky adapters. The PL550D-V2 arrives equipped with a dedicated, native 12V-2×6 (PCIe 5.1) power cable constructed from heavy-duty 16AWG wire. This single, streamlined connector is conservatively rated to deliver up to 300 watts directly to next-generation graphics cards, ensuring clean, consistent, and safe power delivery. Alongside this modern connector, the unit maintains excellent backward compatibility with three standard PCIe connectors and two EPS CPU connectors, perfectly bridging the gap between legacy hardware and the future of PC gaming.

Rock-Solid Reliability and High-Grade Components

Efficiency and durability are at the core of the PL550D-V2’s design. It proudly boasts an 80 PLUS Bronze certification, verifying that it operates at a minimum of 85% efficiency under typical 50% system loads, reducing wasted energy and lowering heat output. The internal architecture utilizes a sophisticated dual-transistor forward topology combined with Active PFC and highly efficient DC-to-DC conversion. By integrating premium electrolytic capacitors, DeepCool ensures this power supply maintains a strict hold-up time of 16ms or greater—even when pushed to 100% full load—allowing your system to smoothly ride out minor power outages and voltage dips.

Whisper-Quiet Cooling and Comprehensive Protection

Thermal management is expertly handled by a high-quality 120mm hydro-bearing (HYB) fan. This specialized bearing design minimizes friction, resulting in exceptional airflow to keep internal components cool while maintaining a remarkably quiet acoustic profile. The build quality is so resilient that the PL550D-V2 is certified to operate flawlessly at extreme altitudes up to 5,000 meters above sea level. Total peace of mind is guaranteed by a full suite of industrial-grade electrical protections (including OPP, OVP, SCP, OTP, OCP, UVP, SIP, and NLO), all backed by DeepCool’s confident 5-year limited warranty.
