DeepCool PL550D at a Glance
Introduction
The DeepCool PL550D V2 550W 80 PLUS Bronze Power Supply (R-PL550D-FC0B-IN-V2) is a non-modular ATX power supply designed for compatible everyday desktops, home PCs and entry-level gaming systems. Its ATX12V 3.1 design brings support for the latest power-supply standard to a budget-conscious build.
The PL550D V2 includes a native 12V-2x6 GPU power cable rated for up to 300W, alongside traditional PCIe 6+2-pin connectors and two CPU/EPS connectors. This combination supports a range of compatible configurations, provided the complete system's power requirements remain within the PSU's capabilities.
An 80 PLUS Bronze certification, 120mm hydro-bearing fan, active PFC and DC-to-DC conversion help deliver practical efficiency and cooling. The unit also specifies a minimum 16ms hold-up time at full load and a range of electrical protection features.
This listing is for the exact Indian V2 SKU. Check the complete part number before purchase because older PL550D listings may describe the earlier ATX 3.0 revision.
Key Features
550W Power Output
Provides 550W of rated power for compatible desktop configurations. Check the CPU and GPU requirements before choosing this capacity for a gaming system.
80 PLUS Bronze Efficiency
DeepCool specifies at least 85% efficiency at a typical 50% load, helping reduce conversion losses under the stated test conditions.
Native 12V-2x6 GPU Cable
Includes a native 16-pin PCIe 5.1 GPU power cable rated for up to 300W, for graphics cards that support this connection and fit the PSU's capacity.
ATX 3.1 Compliance
Designed to meet ATX12V 3.1 requirements, including the specified ability to handle power excursions up to twice total rated system power for 0.1ms.
120mm Hydro-Bearing Fan
A hydro-bearing fan provides airflow to cool the internal components during operation.
Multiple Protection Features
Includes over-power, over-voltage, short-circuit, over-temperature, over-current and under-voltage protection, plus surge/inrush and no-load operation protections.
Power Delivery and Cooling Technology
The PL550D uses active power factor correction (PFC) and DC-to-DC conversion. DeepCool also specifies a dual-transistor forward topology for power conversion.
ATX 3.1 compliance and the native 12V-2x6 connector support compatible modern GPU power configurations. The included 16AWG GPU cable is rated for up to 300W, so this PSU should not be treated as suitable for every graphics card that uses a 16-pin connector.
The manufacturer specifies a hold-up time of at least 16ms at full load and a 100–150ms Power Good signal. These are PSU electrical characteristics, not a replacement for a UPS during a mains outage.
The listed operating temperature range is 0–40°C, and the manufacturer gives a mean time between failures (MTBF) rating of 100,000 hours. MTBF is a statistical reliability figure, not a guaranteed service life for an individual unit.
Technical Specifications
Specifications are based primarily on DeepCool's official PL550D V2 product page. The manufacturer lists the native 12V-2x6 cable as rated up to 300W. Confirm the exact SKU and included cable set on the product packaging.
Ideal Use Cases
Everyday Desktop PCs
A practical option for compatible home, office and study computers used for daily productivity and general computing.
Entry-Level Gaming
Suitable for selected gaming builds with power requirements and GPU connectors compatible with a 550W PSU and its 300W-rated native GPU cable.
Home and Office Workstations
Provides power for compatible productivity systems, including configurations with multiple storage devices and standard peripherals.
Budget ATX Builds
Combines a standard ATX form factor with Bronze efficiency and current-generation power-connector support at a budget-oriented power level.
Before You Build
- Confirm the complete PC's power demand and the graphics-card manufacturer's recommended PSU wattage before purchase.
- The native 12V-2x6 GPU cable is rated for up to 300W. A 16-pin connector alone does not mean the PSU is suitable for every 16-pin graphics card.
- This is a non-modular PSU, so its cables are permanently attached. Plan cable management around the available case space.
- Check the cabinet for ATX PSU clearance and room for cable routing. The PSU measures 150 × 140 × 86mm.
- For higher-power graphics cards, overclocking or substantial future upgrades, consider a higher-capacity PSU with the appropriate GPU connector and power headroom.
Frequently Asked Questions
1. Is the DeepCool PL550D V2 an ATX 3.1 power supply?
Yes. The exact Indian model R-PL550D-FC0B-IN-V2 is listed by DeepCool as an ATX12V 3.1 power supply. Check the full part number because older PL550D versions use the earlier ATX 3.0 specification.
2. Is the PL550D V2 modular?
