Dell's new prebuilt PC has special custom power connector for Nvidia GPU — even large OEMs apparently fear the 16-pin power connector meltdowns

It seems that even an OEM as large as Dell isn't safe from the incendiary woes of the 16-pin connector, as it's taking extra measures to ensure safety. In a Japanese review of the company's "EBT2250" prebuilt by Chimorogu, the teardown reveals a rather interesting approach to supplying power to the GPU inside. The connector is permanently bolted on so it doesn't move even a bit.
DELLのパソコンおもしろい変換使うな、至近距離で曲げるな、とか言われる某コネクタをこういう扱いしてるでも自作PCと違うのはAmphenol製の純正金具を使って強制的に固定してるところ「12V-2x6はしっかり挿し込め」が現状の正解なんでしょう pic.twitter.com/YHgSAgfO1d February 20, 2026
As the picture above shows, Dell uses genuine Amphenol metal fittings to make sure the 12V-2x6 connector is completely fixed in place, unable to accidentally come loose. Amphenol is one of the world's biggest manufacturers of interconnect products. The cable actually plugging into this female connector isn't even a native 16-pin one; rather, it's an adapter that terminates in 2x standard 8-pin PCIe plugs.
For years at this point, we've seen how the 12VHPWR and now the 12V-2x6 connectors are prone to overheating. Countless stories of meltdowns and even the GPU catching on fire are on record, and that's just the documented cases. Different companies have tried different solutions, including active monitoring tools or even building protection right into the power supply. Everything is an effort to fix an issue that simply shouldn't exist.
It's clear that if even Dell has to make sure there's not an ounce of leeway in the 16-pin connection, it's perhaps too fragile or reactive or a connector to begin with. If any of the pins inside stop making proper contact, the other pins become overloaded and start overheating. In a prebuilt that's otherwise completely shut off and has no see-through panels, this is even more of a fire hazard.
The power supply fueling this card is a proprietary unit made by LITEON, a manufacturer in Taiwan. It's a 1000W 80+ Platinum unit with standard connectors, so there's plenty of room for future upgrades. It's likely not a native ATX 3.0/3.1 power supply since it's lacking the 16-pin connectors, forcing Dell to bolt on that adapter. Speaking of which, the GPU is also a Dell-branded version of the RTX 5070 Ti, but its performance is not hindered by its OEM nature.
You can check out the original review if you're interested in the system itself — it's actually a great deal — but the main takeaway was the metal fitting on the 12V-2x6 connector. The funny thing is that the 5070 Ti doesn't even have a large enough power appetite to really require that connector, but you can't really be too cautious. Hence, Dell has also set the GPU on a sag bracket to support its weight. The prebuilt is otherwise fitted with a Core Ultra 275K and 32 GB of DDR5-5600 RAM.
