Lian Li SP750 SFX PSU Review: Powering Your Compact Builds with Gold Efficiency
Table of Contents
Building a small form factor (SFF) PC doesn’t mean you have to compromise on power. The Lian Li SP750 750W SFX PSU proves that, delivering robust and efficient power in a compact package. If you’re planning a high-performance build, especially one utilizing the latest GPUs like the RTX 5070 or RTX 5070 Ti (and you’re wisely avoiding power-hungry processors like the Intel i9-14900KS!), this PSU deserves a serious look. let’s dive into what makes the Lian Li SP750 a standout choice.
Why Choose an SFX Power Supply?
Before we get into the specifics of the SP750, let’s quickly cover why you might need an SFX PSU in the first place. Standard ATX power supplies are… well, standard-sized. That’s great for roomy cases, but in smaller builds, they simply won’t fit. SFX (Small Form Factor) PSUs are designed to maximize space efficiency, allowing you to pack serious hardware into a much smaller chassis. This is crucial for builds prioritizing portability, aesthetics, or simply minimizing desk footprint.
Lian Li SP750: A Deep Dive
The Lian Li SP750 is a fully modular 750W power supply, meaning you only connect the cables you need, reducing clutter and improving airflow within your case. It’s 80+ gold certified, guaranteeing excellent efficiency, and packed with protective circuitry to keep your components safe. Let’s break down the key features:
Compact SFX Form Factor: Designed specifically for small form factor builds.
750W Power Output: Plenty of headroom for modern CPUs and GPUs, including the upcoming RTX 50 series. 80+ Gold Certification: Ensures high energy efficiency,saving you money on your electricity bill and reducing heat output.
Fully Modular Design: Clean up your build and improve airflow by only using the cables you need.
Complete Protection: OCP (over current protection),OPP (over power),UVP (under voltage),OVP (over voltage),OTP (thermal) and SCP (short circuit) provide peace of mind.
Inside the SP750: Quality Components
Lian Li didn’t cut corners when it comes to the SP750’s internals. A key component is the high-quality Nippon Chemi-con 470uF 420 VDC filter capacitor.This contributes to excellent ripple suppression and a decent transient response - meaning stable power delivery even under heavy load. Stable power is critical for the longevity and performance of your components.
Cable Configuration
The SP750 comes with a practical selection of cables:
ATX12V Connector x1
2 x 8 PIN PCIe Connector x1
1 x 8 PIN PCIe Connector x1
* 24-pin Motherboard Connector x1
This configuration should cover most mainstream builds. Always double-check compatibility with your specific components before purchasing.
Performance and Efficiency
Autonomous reviews from reputable sources like AnandTech and TechPowerUp confirm the SP750’s notable performance. It demonstrates great efficiency, notably at around 300-500 watts, and especially when operating at 230 volts AC. While in-rush current is higher at 230V, the overall efficiency and stability are commendable. The ripple suppression is also well-managed, ensuring clean power delivery to your sensitive components.
