Frequently Asked Questions
How much PSU wattage do I need?
Add up the power draw of your CPU and graphics card, add about 100 W for the rest of the system, then leave 20–30% headroom. Most mid-range gaming builds land at 750–850 W. High-end graphics cards often call for 1,000 W or more, so check the maker's recommended PSU wattage for your card.
What does ATX 3.1 mean on a power supply?
ATX 3.1 is Intel's current power supply standard. ATX 3.1 units handle the short power spikes that modern graphics cards create, and they use the 12V-2x6 connector for high-power cards. The C850 Gold Core, for example, is ATX 3.1 with a 600 W 12V-2x6 cable.
What do 80 PLUS Bronze, Gold and Platinum mean?
80 PLUS ratings measure how efficiently a power supply turns wall power into power your PC can use. Higher tiers waste less energy as heat. On 115 V, Gold units must be at least 87% efficient at 20% load, 90% at 50% and 87% at 100%. Platinum raises the bar to 90%, 92% and 89%.
What is a fully modular power supply?
With a fully modular PSU, every cable detaches, including the 24-pin motherboard cable. You connect only the cables your build needs, which cuts clutter and makes cable management and future upgrades easier. Gold Core power supplies such as the C850 Gold Core are fully modular.
Is a quiet power supply worth it?
If you care about noise, yes. Many PSUs have a zero-RPM fan mode that stops the fan at low loads, so the PSU is silent while you browse or work. The C850 Gold Core has a zero-RPM mode and a Cybenetics A++ noise rating.
