Epilogue
Now that I have evaluated all Seasonic’s Focus V4 line members, I have the complete picture, which I can share with you. The new PCB design is interesting but doesn’t offer much in terms of performance and noise output. The small heatsinks undoubtedly play a significant role in this. Although the distance between parts is considerable to allow for adequate airflow, it still cannot compensate for the lack of large heatsinks. Moreover, don’t forget the extended warranty for this product. An extended warranty means that the manufacturer has to play it “safe” with the fan speed profile, or else the elevated operating temperatures can bring trouble in the long run. This is why I no longer care for the provided warranty, as long as it exceeds 2-3 years.
I would like to see the new Seasonic Focus GX units achieving notably higher performance than their predecessors, but this wasn’t the case. Moreover, the 750W model has misconfigured protection features, so my samples died during the evaluation. I am expecting new samples from Seasonic, which will hopefully operate properly. Because I will probably receive this question from readers, I cannot know if the products in stock have the correctly set protection features. Still, I did my part at least, informing Seasonic that it should look into this matter as soon as possible. Because of the not correctly set protection features, this unit cannot get an ATX v3.1 pass from my lab.
The Seasonic GX-750 V4 is expensive for a Gold unit, at $130. There are many offerings in the 850W category at lower prices and with better performance. For example, at the time of the review, the XPG Core Reactor II was at a crazy low price of $85!
Before investing in a new power supply, read my Best ATX v3.x PSUs article to check all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.

Any news about the 750w protection features?
I think you were right and a lot of people who read your review are wondering if the retail 750w model should be considered when making a purchase.
Thanks a lot for all the amazing work.
Would you consider testing the Super Flower Zillion FG ATX3.1/PCIe 5.0 power supplies? I’ve recently stumbled across them as they are currently on sale and was wondering if they were good.
Aris you should review the SuperFlower Leadex III ATX3.0
