Nvidia’s flagship RTX 4090 has a problem beyond simply scaling its large dimensions and rugged nature, with one company producing a custom connector to bypass a related gremlin by squeezing the adapter cable out of the PSU.
Okay, let’s start from the beginning here. The RTX 4090 is known for being a graphics beast, and prospective buyers need to consider several factors: not just the massive cost of the GPU, but other elements as well, like having enough space to fit the thing into a computer case.
Now this might seem like a matter of checking your PC case dimensions against the measurements of the RTX 4090 graphics card you intend to buy – which is quite long and wide no matter which way you cut it – but there is another consideration. which comes into play if you need to use a power adapter.
This applies to many people who don’t have an ATX 3.0 (16-pin) power supply and therefore need to use an 8-pin to 16-pin adapter and cable setup to make the GPU work with their ATX 2.0 PSU. The problem is that the adapter cable can be pretty stiff, so plugging it into the side of the board and bending it to fit inside the case can be tricky (with the RTX 4090 being so wide in the first place, and not leaving much slack in some cases).
This led to some posts on Twitter (noted by Sebastião Castellanos (opens in new tab)) showing frustrated RTX 4090 owners who can’t really fit the adapter without leaving the side panel of the case. This isn’t a great situation, of course, as it leaves the PC exposed to dust and perhaps worse, vulnerable to some sort of spill, or an object thrown out of the way as another example. (It also looks bad, on top of that).
Advance CableMod (as seen by Wccftech (opens in new tab)) common 16-pin connector with 90 degree angle (opens in new tab) which allows the adapter configuration to fit snugly at a right angle, removing the hard cable that doesn’t bend and allowing the side panel to be placed back for affected users.
Review: A lot of considerations for a modern flagship
It’s nice to see a solution quickly appear, though note that you can’t buy the accessory just yet (it’s on pre-order at the end of October).
This entire episode just underlines the problems of large, power-sucking GPUs that leave buyers with much more to consider than the simple cost of the product.
There’s a growing checklist of things like having a power supply powerful enough to run the RTX 4090 (and its other components), fitting it into your case, making sure the adapter fits like we see here, as well as considering the case thermals with the heat the GPU kicks in. And, of course, another potential gremlin is the card’s downfall – the weight of the RTX 4090 pulling down on the PCIe slot it’s installed in.
The last issue is something a European graphics card maker recently addressed with its Gallardo RTX 4090, with a very new solution: a bubble level built into the side of the card to show whether it’s flush in the slot or not. Before long, we’ll have an entire niche industry dedicated to ensuring that high-end GPUs fit and work well in your PC case (well, maybe not, but you get the idea).
