Performance, Performance Per Dollar, Noise & Efficiency Ratings
Performance Rating
The following graph shows the XP1200M's total performance, comparing it to other units we have reviewed. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.
The XP1200M shows poorly overall, mainly because of its not-so-tight load regulation and lousy efficiency levels under light loads. On top of that, most of the competition in this category offers even better ripple suppression. Gigabyte should either use another platform or drop this model's price if it wants to be more competitive.
Performance Per Dollar
The following chart may be the most interesting to many of you because it depicts the XP1200M's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.
The performance per dollar score is naturally fairly low since a high price tag puts the XP1200M in a very competitive space, where you'll easily find another PSU with better benchmark results.
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 28 °C and 30 °C (82 °F to 86 °F).
The XP1200M's overall noise output is very high, so steer clear if you're trying to build a quiet PC.
Efficiency Rating
The following graph shows the PSU's average efficiency throughout its operating range, with an ambient temperature between 28 °C and 30 °C.
In the overall efficiency chart, Gigabyte's XP1200M fails to impress once again. We do have to admit, though, that the difference between Platinum-rated PSUs isn't large at all.
