Epilogue
I don’t have any MSRP information on the Asus Rog Strix 1000W Platinum, which would help me determine if the lack of a totem-pole APFC converter is justified. If the MSRP is high, Great Wall, the OEM of this unit, would have the required headroom to provide a more advanced design and not a plain one, with the only difference with the competition that it uses GaN MODFETs, whose unique features are not exploited. Without having the appropriate design and controller, there is no point in using GaN MODFETs since you cannot increase the switching frequencies high enough to make a real difference from the other platforms using “plain” MOSFETs. A clear example of a PSU fully exploiting the GaN MODFETs is the Corsair AX1600i, which, although it is aged, still is among the best-performing PSUs in today’s market, with its only downside the lack of ATX v3.1 compliance.
The Asus Rog Strix 1000W Platinum achieves a high enough overall performance, is efficient, and has a low overall noise output. Still, if you look at the corresponding Cybenetics report, you will notice a mention of the fan-bearing noise at low fan speeds. The bearing noise might be low regarding dBA, but it is still annoying. This is why I conducted extended noise measurements in this unit, including a frequency analysis. Double ball-bearing fans might have many advantages but have a crucial disadvantage: the bearing noise at low speeds. This is why most brands avoid using them in PSUs, where the fan has to spin at low speeds under light loads, and in most systems, PSUs operate in such conditions. Asus informed me that they would change the fan to another brand, but still to a double-ball bearing model, so until I get a new sample, I cannot be sure whether the terrible fan-bearing noise at low fan speeds will be fixed.
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.

Does anyone know when Asus Thor III 1000w will be released?
I have been using asus thor 1000w p2 for about 1 month. coil whine sound is coming regardless of whether the computer is off or on. the computer case is on my desk 60-70cm away from my ear distance.
coil whine can be from the hardware combination, not only from the PSU. Please note that.
Hi Aris,
Are you going to test the new Asus Thor III 1000w? I ordered the Asus strix ATX3.1 1000w Platinum, but I’m wondering if it’s better to go with the new Thor that was announced today.
In your experience, Great wall vs CWT, which one is better? (As I understood the new Thor is manufactured by CWT)
Hi! Unfortunately Asus marketing doesn’t know my existance. They don’t consider me a KOL (key opinion leader)

aris did u tested some einarex psu, because i’ve seen one of them certified by cybenetics gold, i was wonder about the internals of these psu because my fellow worries about it because it’s not listed at the cybenetics websites, would you review it on hwbusters too ?
Hi! We tested them but have not issued the official certs yet.
I have an insider tip that the Rog Thor III 1200W Platinum is also based on the Enchance (a more advanced platform), so you shouldn’t expect much better performance (+ they replaced the fancy fabric-braided cables with mediocre PVC-braided ones, exactly the same as this one Strix).
In general, we can say that Thor III Platinum has achieved the status of a premium power supply.

Thor III Platinum has lost the status of a premium power supply)
Sad that the GaN mosfets was just a marketing gimmick here. Now I wonder if you can check if this is also the case with the ROG Thor 1200W Platinum III which is, supposedly a more premium plat PSU or if there is no point in it compared to the Strix plat in performance. But also the ROG THOR 1600W Titanium III when compared to the previous Thor Titanium.
