This is a condensed version of my power supply FAQ article, for those who want basic info on what to choose without being overly technical.
-
Don’t cheap out on the power supply but high-end isn’t 100% necessary.
-
Generally, around ~$50 is a good price range.
-
You want 80+ energy efficient, but Gold/Silver/Bronze etc. isn’t THAT important.
-
400-500w should be fine for most builds with entry and mid-range video cards.
-
Processors get more efficient over time (so no need to buy extra wattage).
-
SFX power supplies are compact, but double in price.
-
Modular or semi-modular is strongly recommended.
-
Generally avoid power supplies made over 5 years ago.
