Which one should you choose?
Choose EVGA SuperNOVA 750W Bronze Power Supply if
- You have a standard ATX mid-tower or full-tower case that requires a larger power supply.
- You prefer a hybrid modular design where some cables remain permanently attached to reduce clutter.
- You want a power supply that operates with a standard 120mm fan for consistent airflow.
Choose Lian Li 750W SFX Gold Power Supply if
- You are building in a small form factor case that strictly requires an SFX power supply.
- You prioritize higher energy efficiency ratings to reduce heat generation and power waste.
- You want a fully modular setup with braided cables for a cleaner interior appearance.
Verdict: Choose the EVGA SuperNOVA if you are building a standard-sized PC and need a robust, proven ATX power supply. The Lian Li SP 750 is the better choice for small form factor builds where space and higher efficiency are critical. Both options provide reliable power delivery, so your decision should be driven by your case dimensions.
Efficiency and Form Factor
efficiency rating
The Lian Li SP 750 carries an 80 PLUS Gold certification, which indicates higher energy conversion efficiency under typical loads compared to the EVGA SuperNOVA NEX750B. The EVGA unit holds an 80 PLUS Bronze rating, achieving up to 85% efficiency. For users who prioritize reducing electricity waste and heat generation, the Gold standard offers a clear performance advantage. This difference matters most in systems that run continuously or under heavy sustained loads. You save more energy with the Lian Li unit over time.
form factor
Physical size dictates which cases these units can fit into. The Lian Li SP 750 uses the compact SFX form factor, measuring 4.13 inches in width and 7 inches in height. This allows it to fit into small form factor cases designed for mini-ITX builds. The EVGA SuperNOVA NEX750B follows the standard ATX size, with dimensions of 5.9 inches by 3.4 inches by 7.1 inches. It is built for standard mid-tower and full-tower cases. Your choice depends entirely on the chassis you have selected for your build.
modularity
Cable management affects airflow and aesthetics inside your case. The Lian Li unit features fully modular cabling, meaning you connect only the cables you need. This reduces clutter significantly. The EVGA SuperNOVA NEX750B utilizes a hybrid modular design. This setup typically leaves the main ATX power cables permanently attached while allowing peripheral cables to be detached. Both approaches help reduce internal clutter, but the fully modular Lian Li offers the most flexibility for tight spaces.
fan operation
Noise levels vary based on how each fan operates. The Lian Li SP 750 includes a ZERO RPM mode that keeps the fan completely off when the load is below 40%. This ensures silent operation during light tasks like web browsing or office work. The EVGA SuperNOVA NEX750B uses a quiet 2-ball bearing fan but does not list a zero-RPM feature. It likely spins continuously to maintain cooling. If silence is your priority during low-load activities, the Lian Li design is superior.
protections
Both units include comprehensive safety mechanisms to protect your components. The EVGA SuperNOVA lists specific protections including Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP). The Lian Li data confirms Japanese electrolytic capacitors for durability but does not explicitly list these specific protection types. While both are reliable, the EVGA provides more detailed transparency regarding its safety features.
Which PSU fits your build needs
SFF builders needing compact power
The Lian Li SP 750 uses an SFX form factor, measuring 4.13 by 7 inches. This small size fits tight cases better than the larger ATX unit. You get fully modular braided cables for clean management. The zero RPM mode keeps noise down under light loads, which is ideal for small builds.
Standard ATX cases seeking reliability
The EVGA SuperNOVA NEX750B follows the standard ATX layout. Its hybrid modular design reduces clutter while keeping essential cables attached. You get a 2-ball bearing fan for quiet operation. The high amperage multi-rail design ensures stable power delivery. This unit is built for traditional mid-tower or full-tower PC cases.
Users prioritizing high efficiency
The Lian Li unit holds an 80 PLUS Gold certification. This rating indicates higher energy conversion efficiency compared to the EVGA’s Bronze rating. You save more power during typical loads. The Gold standard means less wasted energy as heat. This makes the Lian Li a better choice for efficiency-focused builds.
