Max Veteran Posted April 20, 2017 Veteran Share Posted April 20, 2017 (edited) If your computer components draw a total of 300w, then it will only draw 300w regardless of how many watts your PSU is able to supply. Your choice of components will affect how much power you use. What is your budget for a PSU? For your setup there, a decent branded 500/550w+ supply will be fine.

Jim K Global Moderator Posted April 20, 2017 Global Moderator Share Posted April 20, 2017 Forgot to include what price range you're looking for. Anyway ... I fill you'd be safe with anything over 500 watts for that particular system. 650 or higher for "future upgrades" ... and a little overhead "just in case." Gotta remember most components now are using the same (or less) energy than products they succeeded. Regarding higher wattage power supplies. If you bought a 3000 watt power supply but your computer only needs 300 watts ... you'll only be pulling around 300 watts from the wall (a little more due to efficiency). Speaking of efficiency ... get one with at least an 80 Plus Bronze (then Silver, then Gold, then Platinum, then Titanium) ... the higher you go the more efficient the power supply is at delivering you power. Higher the efficiency ... the less wattage is pulled from the wall. Regarding brands ... just stay away from unknown (or lesser known brands). eVGA, Seasonic, Corsair, etc., all make fine PSU's. Take a look at the warranty. Link to comment Share on other sites More sharing options...
