jaclaz Posted December 15, 2020 Share Posted December 15, 2020 It depends. The connectors and rails are seemingly "normal" ones, but the overall power is on the low side, 305 W total, 150 W on 3.3/5 V and 264 W on 12 V is not that much. You need to calculate the power requirements of your motherboard+processor+other stuff, there are online calculator for this, examples: https://enermax.outervision.com/ https://www.asus.com/microsite/power_supply_calculator/ https://www.newegg.com/tools/power-supply-calculator/ The most complete/detailed should be: https://outervision.com/power-supply-calculator in "basic" mode should give you an idea, the "expert" mode is needed to have the details of the expected power requirements divided by voltage rails. jaclaz 1 Link to comment Share on other sites More sharing options...
