How to choose the right one
-
Check the efficiency rating
You should look for the 80 Plus Gold certification on both models. This rating indicates that the power supply converts at least 87% of AC power to DC power at typical loads. Higher efficiency means less wasted energy as heat and lower electricity bills over time. Both the 850W and 1000W units share this Gold rating. This ensures consistent performance regardless of which wattage you select for your build.
-
Verify ATX version support
Confirm that the unit supports ATX 3.1 standards. This version ensures compatibility with the latest motherboard power requirements and features. It provides a stable foundation for modern components. Both listed products meet this specification. Choosing a unit with ATX 3.1 compliance future-proofs your system against upcoming hardware changes. It also guarantees that the PSU meets current industry safety and performance benchmarks for desktop computers.
-
Match PCIe connector needs
Ensure the power supply includes a 12V-2x6 connector. This specific connector is required for new PCIe 5.1 graphics cards. It offers a secure connection that reduces the risk of melting or arcing. Both models feature this connector. If you plan to install a modern high-end GPU, this feature is essential. It allows you to plug directly into the graphics card without using multiple adapters or cables.
-
Select the right wattage
Choose between 850W and 1000W based on your GPU and CPU power draw. The 850W model suits mid-to-high-end builds with efficient components. The 1000W unit is better for extreme gaming rigs with power-hungry graphics cards. Consider future upgrades when deciding. A higher wattage provides more headroom for additional components or overclocking. Match the size to your actual system requirements to avoid unnecessary expense or space usage.
-
Prioritize full modularity
Look for fully modular designs to simplify cable management. This feature lets you connect only the cables you need. Unused cables are kept outside the case, improving airflow and aesthetics. Both Auotac models offer this flexibility. It makes building and maintaining your PC easier. You can replace individual cables if they fail without buying a new power supply. This modularity also reduces clutter inside your computer case significantly.
