Spending a thousand bucks or more on a graphics card only to see it burst into flames is a rightful nightmare. The 12VHPWR and 12V-2×6 connectors on the last two generations of Nvidia GPUs have been a constant source of anxiety for PC gamers—and not just gamers, it would seem. A recent Dell teardown shows a custom-made connection that helps secure the power rail in place.
When reviewing the Dell Tower Plus EBT2250 workstation PC, Japanese site Chimolog.co spotted something very interesting when it pulled out the RTX 5070 Ti graphics card: a custom bracket on the power connection, with a logo identifying it as a part from a company called Amphenol, holds the 12V-2×6 firmly to the graphics card. According to machine translation of the exhaustive review, this plastic bracket makes it so that the power connection is “completely fixed [in place] so it cannot come off on its own.”
The 16-pin connectors, which can deliver up to 600 watts of power to a graphics card and more effectively communicate with a sophisticated power supply, have been a source of woe for PC builders. The evidence suggests that it’s easy to install them incorrectly (such that the pins aren’t quite touching), leading to shorts and melted connections. And that’s being generous, assuming that the issues are with the physical design and/or user error, not structural issues with the connectors. The basic design was already revised once, in addition to various enhancements like color-coded slots for a visual indicator of full insertion.
Dell sells the Tower Plus EBT2250 in plenty of markets—heck, it’s not even restricted to business sales, as you can pick one up at Amazon or Micro Center. But the Chimolog review (spotted by Tom’s Hardware) seems to be the first to make note of custom hardware designed specifically to secure the 12V-2×6 connector.
That’s not shocking, as these pre-built desktops aren’t aimed at gamers or DIY types (though it certainly has enough power to be a pretty good gaming PC!). I wonder how many other pre-builts are shipping with extra clips and clamps for peace of mind, and if there might be a market for selling directly to PC builders like me.
