Design & Build Quality

The SST‑SX500‑LG v2.1 UK showcases a robust black aluminum chassis that not only looks sleek but also aids in heat dissipation. The internal layout is meticulously engineered to keep airflow efficient, with a dedicated 120 mm fan positioned for optimal intake and exhaust paths.

Its compact dimensions make it an ideal choice for SFX‑L compatible cases, allowing builders to create ultra‑compact systems without compromising on power or reliability. The unit’s low profile also ensures that it fits comfortably behind a motherboard in tight spaces, providing flexibility in cable management and component placement.

Performance & Efficiency

The 80 Plus Gold certification guarantees high efficiency across the load range, reducing power loss and heat generation. At typical loads (30–70 % of rated capacity), users can expect efficiencies between 88 % and 90 %, translating to lower electricity bills and a cooler operating environment.

The active PFC feature further refines power delivery by converting the input AC voltage into a clean DC signal before it reaches the internal circuitry. This results in stable voltage rails, which is crucial for overclocking, high‑end GPUs, and demanding workloads.

Noise Management

The 120 mm fan employs PWM control to adjust speed based on load, ensuring that the unit remains quiet under light usage. Even at full load, the noise level stays below 30 dB(A), making it suitable for silent builds and home office setups where low acoustic output is a priority.

Modular Cable System

A fully modular design means that only the cables you need are connected, eliminating clutter and improving airflow inside the case. The included cable set features:

• 1× 20‑pin + 4‑pin ATX12V (CPU)
• 1× 8‑pin EPS12V (CPU)
• 2× 6‑pin PCIe (GPU)
• 2× SATA (storage)
• 3× Molex (legacy devices)
• 1× 4‑pin peripheral (USB, audio)

All cables are reinforced with high‑quality connectors and have a generous length to accommodate various case layouts.

Compatibility & Use Cases

• Mini‑ITX / Micro‑ATX builds: Perfect for compact gaming rigs, media centers, or home theater PCs.
• Workstations: Reliable power for CPU‑heavy tasks such as video editing, CAD, and scientific simulations.
• Silent systems: Low noise output makes it ideal for audio production studios and quiet office environments.
• Custom enclosures: The SFX‑L form factor allows integration into bespoke chassis or DIY projects where space is at a premium.

Installation & Setup

Installing the SST‑SX500‑LG v2.1 UK is straightforward:

1. Mount the unit in an SFX‑L compatible case using the provided screws.
2. Connect the 20+4 pin ATX12V and 8‑pin EPS12V cables to the motherboard.
3. Attach PCIe power cables to GPUs, SATA cables to storage devices, and Molex or peripheral cables as needed.
