When building or upgrading a PC, choosing the best power supply for PC is crucial. A power supply unit (PSU) is the backbone of your system, ensuring stable and efficient power delivery to all components. Whether you’re assembling a budget build or a high-end gaming rig, picking the right PSU enhances performance, efficiency, and longevity. In this guide, Newegg’s experts will help you understand the key factors in selecting the best power supply for PCs, including wattage, efficiency ratings, and form factors.
How to Pick the Best Power Supply for PC?
When selecting the best power supply for PCs, consider the following factors:
1. Wattage Requirements
Determine the total power consumption of your components. Use an online PSU calculator to estimate the wattage required based on your CPU, GPU, and peripherals. For example, high-end GPUs like the RTX 4090 demand the best power supply for RTX 4090 with at least 1000W for stable performance. You don’t want to end up buying a heavy power supply if your pc doesn’t carry that much weight.
2. Efficiency Ratings
A lot about the power supply revolves around the efficiency of your power supplier. So, look for the efficiency rating at all times. Look for an 80 PLUS certification, which ensures energy efficiency. The ratings range from Bronze, Silver, Gold, Platinum, and Titanium, with higher tiers offering better efficiency and reduced heat output.
3. Modular vs. Non-Modular
This is a common choice that any buyer should look out for when buying power supplies for their PCs. A modular power supply for a PC allows you to connect only the cables you need, reducing clutter and improving airflow. Fully modular PSUs are ideal for clean builds and cable management.
4. Form Factor and Compatibility
Ensure your PSU fits your PC case. Look for the model and size to make sure it will fit your PC. Some may have larger sizes and some smaller, which are all for different models. Standard ATX PSUs work for most builds, while compact cases may require SFX or SFX-L PSUs.
5. Connectivity and Future-Proofing
The latest models will have different connectivity ports and plug-ins. Check the description carefully when buying one. Make sure the PSU has enough PCIe, SATA, and EPS connectors for your components. If upgrading to high-power GPUs like the RTX 4090, choose an ATX 3.0 PSU with PCIe 5.0 support.
