Overview

The ouquckl 250AB-24 is a 1U form-factor switching power supply unit designed for space-constrained server chassis and compact desktop PCs. It supports a wide input voltage range of 100-240V AC and is available in four output variants: 200W, 250W, 400W, and 500W. The metal casing provides durability and adequate heat dissipation. Built-in short-circuit and over-current protection ensure safe operation for connected components. This PSU is a practical choice for budget-conscious users building entry-level servers, NAS systems, or small form-factor desktops.

Key Features

Multiple wattage options: Choose from 200W, 250W, 400W, or 500W to match your system's power requirements. The 500W model can comfortably power entry-to-mid-range server builds or integrated-graphics desktops. Ultra-compact 1U size: Measuring approximately 150x80x40mm, this PSU fits perfectly into 1U rack-mount chassis and Mini-ITX cases where internal space is at a premium. Comprehensive protection: Short-circuit protection (SCP) and over-current protection (OCP) are included as standard, safeguarding your hardware against electrical faults. Wide voltage compatibility: Accepts 100-240V AC input, making it suitable for international use or regions with unstable power grids. * Standard motherboard connectors: Features a 20+4PIN main connector and an 8PIN (4+4PIN) CPU connector, ensuring broad compatibility with modern ATX and Micro-ATX motherboards.

Compatibility Guide

This PSU is exclusively designed for 1U form-factor chassis. It is not compatible with standard ATX power supply mounting points. The 20+4PIN main connector and 8PIN CPU connector work with most ATX and Micro-ATX motherboards. However, there are no dedicated PCIe power connectors for graphics cards. If you plan to use a discrete GPU, you will need to purchase a separate adapter or use an external power source. The 500W model is sufficient for CPUs with up to 95W TDP and integrated graphics, but high-end gaming GPUs will exceed its capacity.

Best Use Cases

Building a 1U rack-mount server: The compact size and stable power delivery make it ideal for home labs or small business servers. Constructing a compact Mini-ITX desktop: When paired with a 1U-compatible case, this PSU saves valuable internal space while providing reliable power. * Budget-friendly NAS or firewall appliance: The 500W model offers enough headroom for low-power builds without breaking the bank.

Things to Consider

This PSU is strictly for 1U chassis; it will not fit standard ATX cases. Verify your case compatibility before purchase. The lack of PCIe power connectors means it is not suitable for gaming PCs with discrete graphics cards unless you use adapters (which may not be ideal for high-power GPUs). The 500W model is adequate for entry-level to mid-range systems, but high-end components will require a more powerful unit. Additionally, ouquckl is a lesser-known brand, so warranty and support may be limited compared to established PSU manufacturers like Seasonic or Corsair.
