This article covers 24PIn HK300.

Overview

The ouquckl HK300-41GP is a 250W silent power supply unit designed for small ITX desktop systems. It features a 24-pin ATX motherboard connector, a 4-pin CPU power connector, and one IDE connector. The unit delivers 250W continuous output at 40°C operating temperature and includes overcurrent, overvoltage, and short-circuit protection. Its compact dimensions (approx. 12.5×10×6.5 cm) make it suitable for space-constrained builds. This PSU is ideal for point-of-sale (POS) systems, embedded applications, or low-power ITX DIY PCs. With 250W capacity, it pairs well with CPUs that have integrated graphics or low TDP (e.g., Intel N-series, AMD Athlon). However, it is not suitable for gaming GPUs or high-performance CPUs, so clear use-case planning is essential.

Key Features

250W continuous output (at 40°C): Provides stable power for small systems, suitable for 24/7 operation. 24-pin ATX + 4-pin CPU + IDE x1: Compatible with standard ITX motherboards and legacy IDE storage. Overcurrent, overvoltage, short-circuit protection: Multiple safeguards protect your system from electrical faults. Silent cooling fan: Low-noise fan keeps operation quiet while maintaining thermal performance. * Compact size (12.5×10×6.5 cm): Fits easily into tight ITX cases, offering flexible cable routing.

Compatibility Guide

Form factor: Designed for ITX desktop cases. May not fit standard ATX cases; verify PSU mounting holes beforehand. Motherboard power: 24-pin ATX connector works with most ITX motherboards. CPU power: 4-pin CPU connector supports entry to mid-range CPUs (up to ~65W TDP). Not compatible with motherboards requiring 8-pin CPU power. Storage: One IDE connector. No SATA power connectors included; use adapters for SATA drives. * Graphics: No GPU power connectors. Only integrated graphics configurations are supported.

Product Info

Model: HK300-41GP Brand: ouquckl Output: 250W (also listed as 200W; actual rating 250W) Input voltage: 220V (check if 100V operation is supported for Japan use; a step-down transformer may be needed) Protection: Overcurrent, overvoltage, short-circuit Cooling: Internal silent fan Connectors: 24-pin ATX x1, 4-pin CPU x1, IDE x1 Dimensions: Approx. 12.5×10×6.5 cm * Warranty: Manufacturer-dependent (check product page)

Best Use Cases

Low-power ITX DIY PC builders: Ideal for office PCs, media servers, or NAS systems that draw under 250W. POS or embedded system PSU replacement: High compatibility with existing POS machines and industrial PCs. * Users prioritizing silence: The silent fan makes it suitable for noise-sensitive environments like bedrooms or libraries.

Things to Consider

This PSU's 250W capacity is insufficient for gaming PCs or high-performance workstations. The lack of SATA power connectors means you'll need adapters for modern SATA SSDs/HDDs. Additionally, the 220V input rating may require a step-down transformer for use in Japan (100V) unless the unit supports a wide voltage range—verify before purchase. The brand ouquckl is relatively unknown, which may raise concerns about long-term reliability and support. If budget allows, consider established brands like Seasonic or Corsair for similar low-wattage PSUs.
