500 Watt Power Supplies

Key takeaways

• 1,901 listings match this collection right now.
• At 500 watts, server and desktop units deliver their full rated output on a standard 100 to 240 volt input, unlike the 1400 and 1600 watt classes.
• 500 watts covers a single entry-tier processor and a handful of drives, but pairing two mid-range processors pushes combined draw past this class, into 750 watt territory.
• This wattage covers single-socket servers and light multi-drive towers without headroom for a GPU or a high-TDP dual-socket build, sitting at the low end of the server lineup.
