LIAN LI SP750 750W 80+ GOLD SFX — Black

The LIAN LI SP750 is a 750 W fully modular SFX power supply designed for compact and small-form-factor PC systems. It features 80 PLUS Gold certification, an active PFC design, a high-power +12 V rail rated at 744 W, and a 92 mm FDB fan with a fanless mode up to 40% load.

Product Information

Power Specifications

The 744 W combined +12 V capacity allows the SP750 to deliver the majority of its rated power through the +12 V rail for CPU and graphics-related loads.

Cooling System

• Fan size: 92 mm
• Bearing type: Fluid Dynamic Bearing (FDB)
• Fan speed: 1,000–2,800 RPM
• Fanless mode: 0 RPM operation up to approximately 40% load
• Noise level: 17.1–43.1 dBA
• Operating temperature for the published noise figures: 25°C ambient

The fanless operating mode is designed to reduce acoustic output during lower-load operation, while the FDB fan increases its speed as PSU load rises.

Protection Features

The SP750 incorporates the following protection circuits:

• OCP — Over Current Protection
• OPP — Over Power Protection
• UVP — Under Voltage Protection
• OVP — Over Voltage Protection
• OTP — Over Temperature Protection
• SCP — Short Circuit Protection
