The following graph shows the GP-AP850GM’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.
This is a highly capable platform, able to meet eye-to-eye strong opponents like the RM850x, HCG850 and the HX850.
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.
For an 80 PLUS Platinum and ETA-A unit the GP-AP850GM has a fair price tag. A bit lower price though it would surely help.
The graph below depicts the cooling fan’s average noise over the PSU’s operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).
Under normal operating conditions the fan profile is not aggressive, however if you push the unit the fan will make its presence felt. This is not a noisy 850W PSU, however it is not among the most silent either.
The following graph shows the PSU’s average efficiency throughout its operating range, with an ambient temperature close to 30°C.
The overall efficiency is up to the expected levels, given this platform’s certifications (Platinum and ETA-A).
