So, What Did We Learn Today?

At the end of this little analysis, we can summarize our findings in five concise bullet points.

  1. Choosing the right capacity is often more effective than choosing the wrong PSU with a higher efficiency rating.
  2. Buying too big just to be on the safe side is counter-productive and only makes sense if you actually need the reserves.
  3. Affordable 80 PLUS Gold and Bronze power supplies make sense in systems with a large power window.
  4. Don’t blindly believe the wattage numbers on the box. Be smart, think logically, check the numbers and do the math yourself.
  5. Stay away from offers that are too good to be true. You can’t get a good 500 W power supply for 40 bucks. That “bargain” might just blow up in your face. Literally.

But that doesn’t mean it’s unimportant, and cutting corners to save money may end up costing you a lot more in the long run.
