The Thermaltake GF3 model with 1000 W max power is a fully ATX v3.0 and PCIe 5.0 compatible PSU. These are its significant assets, with high build quality and good overall performance following. This unit doesn't pose a severe threat to the high-performing Corsair RM1000x and EVGA 1000 G7 models, but none of them feature a native 12VHPWR connector, nor are they ATX v3.0 ready. So far, there are not many Gold efficiency PSUs with 1000 W max power meeting the strict ATX v3.0 requirements for units with 12VHPWR connectors. The list is pretty short, and in my graphs, besides the GF3 1000, the only other PSUs that are ATX v3.0 compatible are the SilverStone DA1000 Gold and the Corsair RM1000e, which might offer ATX v3.0 compatibility. Still, the RM1000e doesn't come with a 12VHPWR cable, to lower the production cost. You have to purchase this cable from Corsair, should you need it.

Given that the NVIDIA Ada Lovelace GPUs don't require ATX v3.0 PSUs and the upcoming AMD GPUs won't even require 12VHPWR connectors, many users will prefer to keep their older PSUs, and use adapters in case they need 12+4 pin connectors. There were some issues with these adapters. You need to ensure the connection is secure and you hear the "click" before you power up the system and stress it. In some cases, I noticed that you don't hear this "click," so you have to ensure that the connector is all the way into the socket for optimal conductivity. I was always against the use of an adapter, especially for high-power applications, but if you own a be quiet!, Corsair or Seasonic PSU, you can order a native 12VHPWR cable, which will be able to deliver up to 600 W without any issues, assuming that the PSU you will use will be able to keep up. So, if you have a good PSU, there is no need to change it for the moment. On the other hand, if you are out searching for a future-proof PSU, you can get an ATX v3.0 and PCIe 5.0 ready one, since eventually, all graphics cards will use 12+4 pin connectors. The Thermaltake GF3 1000 W is a decent choice, and with a lower price of around 180 dollars, its performance per price ratio would get a nice boost.
