The Enermax PlatiGemini 1200W is the first PSU I have ever evaluated supporting both ATX12V and ATX12VO standards, making it as future proof as possible. At the same time is is ATX v3.1 compliant, meaning that it can deliver 200% of its max power for short periods (0.1ms).
The Enermax PlatiGemini 1200W will be included in my best ATX v3.x & PCIe 5.x PSU picks article.
An interesting article about ATX v3.0 and v3.1 PSUs:
It was about time for something exciting to happen in the PSU market. After Corsair’s RMx Shift models, with the side modular panel, nothing new appeared on the market. This changes with the Enermax PlatiGemini 1200W, which might have a conventional exterior design (with extra compact dimensions, given its capacity). Still, it is the first PSU supporting the ATX12V (ATX v3.1) and ATX12VO standards without additional adapters, just through a simple cable change.
Thanks to an intelligent design, this PSU can output 5VSB and 12VSB, and thanks to the ATX cables provided, it supports 12VO and ATX12V mainboards. Admittedly, the ATX12VO standard doesn’t go as Intel planned, with very few mainboards supporting it, and its future doesn’t seem to be bright. Still, Enermax decided to offer a PSU compatible with it while retaining compatibility with the widely known ATX12V.
Another unique characteristic of the Enermax PSUs, which works pretty well, is the patented Dust-free Rotation (D.F.R) function, where the fan operates reversely during the start-up phase to remove the dust outside of the PSU’s internals. There is also a DFR switch button if you want to do that manually. The PlatiGemini 1200W features Cybenetics Platinum certification at 115V and a Cybenetics Standard++ (30-35 dB[A]) noise certification. Its cables are modular, and with only 150mm depth, it is among the smallest in size, 1200W PSUs. The cooling fan uses a double-ball bearing for increased tolerance to high temperatures, and the provided warranty is ten years long.

This seems like a great choice for a PSU, but the underperforming OPP and OCP protections are holding me back from buying it. Have there been any known updates to address this? Since I am not an electrical engineer, I am left wondering what the worst case scenario is for these shortcomings- i.e., damaged pc components, house burns down, etc… Thanks in advance for any update.
