Specifications side by side

How to choose the right one

1. Check ATX Version Support

   Modern graphics cards often require specific power standards. The Lian Li EG1000G and SX1000P both support ATX 3.1. This standard ensures compatibility with newer NVIDIA RTX series cards. If you plan to use a high-end GPU, verify the PSU meets the latest spec. Older units may lack the necessary native cables. This prevents the need for risky adapters. Always match the version to your current or future GPU requirements for stable power delivery.

2. Evaluate Efficiency Ratings

   Efficiency ratings indicate how much power is wasted as heat. Most listed models carry an 80 Plus Gold certification. This means they convert at least 90% of AC power to DC at typical loads. The SX1000P reaches Platinum status for even lower waste. Higher efficiency reduces electricity costs and heat output. This is crucial for quiet operation in small cases. Gold is sufficient for most users, but Platinum offers better performance for high-wattage builds.

3. Verify Modularity Type

   Modularity affects cable management and airflow. The SP 750 Gold SFX is fully modular. This allows you to connect only the cables you need. Unused cables do not clutter the case. This improves air circulation and makes installation easier. Non-modular units require all cables to be routed, even if unused. For compact SFX builds, this extra space is valuable. Check if the unit offers fully modular connections for the cleanest possible setup.

4. Match Physical Dimensions

   Size constraints are critical for small form factor builds. The SP 750 SFX measures 4.13 by 7 inches. This fits into tight chassis where standard ATX units will not. The EG1000G ATX unit is 3.39 by 5.91 inches. Always measure your case interior before purchasing. An incorrect size will prevent installation. SFX units are smaller but may have different mounting hole patterns. Verify the physical footprint matches your case specifications exactly.

5. Assess Wattage Needs

   Select a wattage that supports your components without excessive overhead. The RS1200G offers 1200W for high-end systems. The SP 750 provides 750W for mid-range builds. Choose a unit that meets peak load requirements. Running a PSU near 100% capacity generates more heat. Aim for 50-80% load for optimal efficiency. Ensure the unit has enough headroom for future upgrades. This prevents system instability during heavy gaming or rendering tasks.
