Performance Rating
The following graph shows the HX750’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.
As you can see in the graph above, the HX750 achieves a higher overall performance score compared to the HX750i, mostly thanks to the Type-4 cables that it uses which feature extra ripple filtering caps. In general this is a very good performing PSU, meeting eye-to-eye the performance of some fresh platforms.
Performance Per Dollar/Buck
The following charts may be the most interesting to many of you because they depict the product’s performance-per-dollar and performance-per-pound scores. 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 PSU.
With a 150 bucks price tag, this is not an affordable 750W PSU, so inevitable its performance per buck score is not that high.
In the UK the HX750 is sold for 160 pounds in Overclockers UK, so it is quite expensive.
Noise Rating
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).
If you need a silent operating system, then this is the suitable power supply.
Efficiency Rating
The following graph shows the PSU's average efficiency throughout its operating range, with an ambient temperature close to 30°C.
Efficiency wise the HX750 goes well, given its official efficiency certifications.
