Save a huge 47% off on this top-ranked EVGA 500W PSU for your ATX PC build

[Windows Central]

When it comes to power supplies for your PC, there are ones certified 80+ Gold, and then there's the rest. What's the point of 80+ Gold? It ensures the power supply unit (PSU) is up to snuff for output, making it much more efficient than other PSUs. That means, in the long run, you end up paying less money because the system uses that power instead of wasting it. With an 80+ rating, you're getting a PSU with an efficiency of at least 80% when at 20%, 50%, and 100% loads. More electricity routed to your hardware (instead of being turned into wasted heat) is an awesome thing.
