The Lian Li SP750 power supply case is painted in black with the company and product name.
A 92x92mm fan is responsible for cooling, and the Lian Li logo has been milled into aluminum above it.
The Lian Li SP750 has a silent mode, so the fan only starts spinning at 40% or 300W load.
The fan in this case is a Yate Loon D92LH-12B. This fan is not the best that Yate Loon has to offer, but it serves its purpose.
The power supply is fully modular and offers all the connections you need. These are of course also coded, marked and thus protected from confusion.
By the way, the LianLi SP750 doesn’t have a switch on the back to change the voltage from 115/230V, so you can’t go wrong here.
Let’s take a look inside the power supply, which shows a high quality of the SP750. High quality Japanese capacitors, also everything is very cleanly finished. The black hot glue ensures that the user is not bothered by coil whine. By the way, the power supply is manufactured by Helly Technology OEM Manufacture.
Here you can see the large Japanese bulk capacitor.
And here you can see a picture of the ANPEC APW7159B PWM controller.
Of course, the power supply also has all the protection circuits that should be standard nowadays. With overload protection (OPP), overcurrent protection (OCP), overtemperature protection (OTP), undervoltage protection (UVP), overvoltage protection (OVP) and short-circuit protection (SCP), you are on the safe side here. The certification logos on the casing show that all safety standards are met.
The efficiency curve here shows how well the power supply works at the respective load condition. As usual, the efficiency is always slightly better with a 230V load than with 115V.
The cable length should also be sufficient for larger cases. The PCIe cables for the graphics card as well as the ATX cable and the CPU cable are sleeved individually, the remaining cables are designed as flat ribbon cables.
