Lian Li SP750 Power Supply Review High-Performance SFX PSU for Compact PCs

Description

Sleek Design and Compact Form Factor

I was immediately struck by the sleek black aluminum housing of the SP750 power supply. Its modern aesthetic is a standout feature, and it feels like it was designed specifically to complement high-end, small-form-factor PCs. The compact dimensions make it an ideal choice for SFX builds, especially when space is at a premium. It also comes in an all-white design option, which adds versatility for those aiming for a specific build theme. I appreciated how it blends seamlessly into my setup without drawing unnecessary attention.

Performance and Efficiency

Performance-wise, this power supply doesn’t disappoint. Boasting an 80 PLUS Gold certification, it delivers up to 92% efficiency, which means less power wastage during operation. I noticed that even under heavy load, the unit remained stable and consistent. For anyone using power-hungry components, such as high-end GPUs or overclocked CPUs, this PSU handles the demand without flinching. The efficiency rating is particularly impressive, as it directly translates to lower electricity bills and less heat being generated.

Cooling and Quiet Operation

One of the standout features is the 92mm hydraulic bearing fan, which operates in zero RPM mode under a 40% load. In my experience, the fan stayed completely silent during moderate workloads, which made my entire system whisper-quiet. Even during peak performance, the noise was barely noticeable. This feature is a game-changer for anyone who prioritizes a quiet workspace or gaming environment. The efficient cooling system ensures the PSU doesn’t overheat, even during extended usage.

Premium Components for Durability

Another aspect that stood out is the use of premium Japanese electrolytic capacitors. These components are known for their durability and reliability. They provide long-term stability, which is crucial for a power supply. I felt reassured knowing that the internal components are built to last, minimizing the risk of failure over time. This attention to detail is a strong selling point for anyone looking for a dependable PSU.

Fully Modular Design and Cable Management

Cable management is always a challenge, but the fully modular design of the SP750 makes it a breeze. It comes with braided cables, which not only look great but also feel sturdy and tangle-resistant. I loved how easy it was to connect only the cables I needed, reducing clutter inside my case. This feature not only improves aesthetics but also enhances airflow, which is a critical factor in small-form-factor builds. The thoughtful inclusion of these cables saved me from purchasing additional accessories.

Key Benefits

• Compact size perfect for small-form-factor PCs.
• 80 PLUS Gold certification ensures high efficiency and reduced energy costs.
• Silent operation with zero RPM fan mode under light loads.
• Premium Japanese capacitors for durability and long-term reliability.
• Fully modular design for excellent cable management.

Caveats

• Limited to 750W, which might not suffice for ultra-high-end systems with multiple GPUs.
• The price point may feel steep compared to non-modular or lower-rated PSUs.
• Availability can be an issue, as it’s not always in stock due to high demand.

Market Rivals

When comparing the SP750 to competitors like the Corsair SF750 and SilverStone SX750, a few things stood out. The Corsair SF750 offers similar performance and efficiency, but its fan noise is slightly more noticeable under load. On the other hand, the SilverStone SX750 provides excellent build quality but lacks the same level of modular cable management and aesthetic appeal. The SP750 excels in silent operation and design, making it a more attractive option for those prioritizing a quiet, visually cohesive build. However, for users who need more wattage or specific features like RGB lighting, rival brands might offer better alternatives.

Cost-Effectiveness

Considering the premium features and build quality, the SP750 offers excellent value for money. While it might be pricier than some budget options, the efficiency, durability, and aesthetics justify the investment. I found that its long-term reliability and reduced energy costs balance out the initial expense. If you’re building a compact PC and want a high-performance, stylish PSU, this model delivers on its promises without cutting corners.
