The following graph shows the TPG-750AH3FSGR’s total performance rating, comparing it to other units we have tested. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.
The overall performance is not that high, with the RM750x and the SSR-750FX being far away. The 650W model follows closely the 750W unit.
Performance Per Dollar
The following chart may be the most interesting to many of you because it depicts the product’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. Note that all of the numbers in the following graphs are normalized by the rated power of each unit.
The lower capacity model achieves a higher price per buck score, thanks to its lower price.
Normally the smaller unit should be 2-3 dB(A) quieter.
Almost the same overall efficiency for both units.
