So, What Did We Learn Today?
At the end of this little analysis, we can summarize our findings in five concise bullet points.
- Choosing the right capacity is often more effective than choosing the wrong PSU with a higher efficiency rating.
- Buying too big just to be on the safe side is counter-productive and only makes sense if you actually need the reserves.
- Affordable 80 PLUS Gold and Bronze power supplies make sense in systems with a large power window.
- Don’t blindly believe the wattage numbers on the box. Be smart, think logically, check the numbers and do the math yourself.
- 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.
Don't Say We Didn't Warn You!
Consider this image a warning that’s only partly tongue-in-cheek. We hope our analysis has helped clear up some common misconceptions and maybe even given you a new perspective on the mundane world of power supplies. It may be a component that gets less attention than CPUs and graphics cards. After all, it's a loss less visible, and its performance characteristics are not as impressive. 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.
