Why you can trust Tom's Hardware
Performance, Value, Noise & Efficiency
The following graph shows the GX-F750'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.
Cougar's overall performance score is close to what the Seasonic Focus Plus Gold 750 achieves. That model shares the same ETA and LAMBDA scores, and is also 80 PLUS Gold-certified. Corsair's RM750x scores a lot higher, but also costs more.
Performance Per Dollar
The following chart may be the most interesting to many of you because it depicts the unit'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.
Although the GX-F750 isn't available yet in the U.S., we converted its price in EUR to see that it achieves a fairly high performance-per-dollar score.
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).
Cougar's offering barely beats Seasonic's Focus model when it comes to noise output measurements. The Antec and FSP PSUs land below 30 dB(A), while Corsair's RM750x plays alone under 20 dB(A).
The following graph shows the PSU's average efficiency throughout its operating range, with an ambient temperature close to 30°C.
The overall efficiency score from thousands of different load combinations puts the GX-F750 ahead of Seasonic's Focus platform and the RM750x.

Nice review! The platform's codename is TPK.Reply
Thanks Orion! Will update the part's table.Reply
All of Cougar's PSUs are made by HEC/Compucase, an OEM with many years of experience in this field.
HEC/Compucase, for at least the last decade hasn't been known to produce a single good unit. Cougar would do well to find a better OEM.
I'd love for HEC to have finally get a good platform though... AND never go back to less.
Not a FAN of HEC powere supplies , but a great review , Thanks Aris.Reply
Looking at the comparison products, are these numbers for the EVGA 750 G3 or the B3? If the everything is pointing to the G3 (including the cost), that definitely seems like the value leader. If the cost is pointing to the B3, then it could change the story quite a bit.Reply
However, I also see that the RM750x appears to have dropped in price, which would likely put it at the top of the value chart.
