Does Upgrading A Power Supply Make A Difference In A Gaming PC?

Gaming Power Supply

The answer depends on how much money you're willing to spend. An upgrade will usually improve performance by at least 10%, but that improvement might only last for a few months.

Introduction

The first thing we noticed when comparing the two units was how quiet they were. The high-end unit had a much quieter fan than the low-end unit. This made us wonder whether the higher quality power supply would make any difference in performance.

We put it to the test to find out.

We tested two identical gaming PCs with different power supplies. One was a $100 budget model and the other was a $300 high-end unit. Both were equipped with the same motherboard, processor, RAM, hard drives, and graphics card. The only difference was the power supply.

Testing Methodology


Corsair HX750i V2

We tested both units using our standard test methodology. Each unit was connected to a Corsair HX750i V2 motherboard with an Intel Core i7-4790K processor running at 4.0GHz. Both units were then run through the same set of benchmarks.

Results

Our tests show that the Corsair AX1200i has better performance than the Seasonic S12II. It also has lower noise levels and higher efficiency ratings. This means that the AX1200i will provide more consistent power output throughout its lifespan.

Conclusion

If you’re looking for a high-quality gaming computer with good value, then the Corsair AX1200i should be at the top of your list.
