Given the unit’s high capacity, the OCP at 12V and OPP are reasonably set. On the other hand, the minor rails, especially the 3.3V rail, have highly set OCP triggering points. The rest of the essential protection features are present and operate correctly.

I just received my TT GF A3 1050W today and I was pretty surprised to see a TT-1225 fan inside it.
I got it on amazon.fr, sold by amazon itself.
What is your opinion on Stop-Fan features for powersupply ? Do you think it’s better to keep the fan running all the time for better cooling, or is it better to enable the stop-fan feature for less dust and less wear on the fan?
Thank you so much for your awesome reviews!
TT GF A3 1050 There are two production factories,hkc/China(ce link),TTP-1050FKG and TTP 1050FLG

Hi Aris! Am contemplating on buying the GF A3 1050W, but am not sure if it’s compliant with your advice here: https://hwbusters.com/psus/how-to-select-a-new-psu-now-with-the-12vhpwr-upcoming-change/
It has a 12VHPWR but what about 2×8 pin? It says 6+2 on the CPU/PCIE connectors. Is it the same as the 8pin you mention? Is this a future proof PSU for the 3.1 standard like you mention in your article?
Also, I would gladly buy from your eshop if you can suggest an 1000W+ silent PSU under 200eu that would be future proof for ATX 3.1.
Hi Thanos, the sockets on the PSU side are not the problem, but the ones on the GPU are usually the culprits behind melting connectors, etc.
The new connector is just safer, protecting from misuse. I have used 12VHPWR from day one and installed numerous PSUs and GPUs without any issues. From PSUs, I don’t even remember what we have on our site.

There is so much options I’m unsure which powersupply to buy around 130-160 euro, I want to avoid a direct 16 to 16pin connection also as I’d feel more secure with a 2×8 to 16 pin connection. I had the RM1000e but it had horrible knocking sounds from the fan so I returned it.
Corsair RMx Shift then
Would it be the best go to option do you think? I see also the NZXT c1000 but I’m unaware how well any of their products perform other than AIOs.
GF A3 is by HKC, using a rather new platform. The NZXT C1000 uses CWT CSZ platform, which has higher build quality (better caps), identical to the GF3 units. If the price difference is high, go for the GF A3, else C1000 or TT GF3 1000W which practically is the same as the NZXT.
