'I would stay as far away from the Founders Edition 5090 as I possibly can,' says one experienced re

Given the huge amount of heat that GeForce graphics cards can generate, it's no surprise that some PC enthusiasts turn to water blocks to tackle the blaze. However, one experienced repair technician has discovered that should you make a mistake during the process of disassembling the card and applying the water block, and damage an internal connector, the whole thing will be borked because there's no replacement for it.

That's according to (via ) in a recent YouTube video, covering a repair case it was hired to fix. A customer had sent in a non-functioning RTX 5090, which had failed after trying to apply a water block to it.

Unlike most graphics cards, Nvidia's comprises two circuit boards: the primary one, which houses the GPU, VRAM, and power delivery, and a smaller secondary board for the PCIe slot connector.

The two boards click together via a fixed mechanism, rather than a ribbon cable, a bit like a very small PCIe slot. In NorthridgeFix's own words, it is a "stupid design" because it is "very fragile". It's this particular connector that had broken when the customer had tried to put their RTX 5090 [[link]] FE back together after applying the water block.

Ordinarily, this wouldn't be a problem for a decent repair technician, because they can simply desolder the old one and slap on a new set. However, in the case of Nvidia's RTX 5090, there's just one teensy problem: you can't buy a replacement set, and because the connection system is proprietary to Nvidia, you can't swap it for a general connector either.

Cue several thousand dollars' worth of dead GPU, all for the sake of a single connector.

One might have little sympathy for the customer for not being careful enough when handling such an expensive piece of kit. Accidents happen, though, and I've permanently killed a [[link]] couple of high-end motherboards in the past 14 months, through very minor incidents that unfortunately resulted in them being permanently toast.

So, is NorthridgeFix correct? Should we avoid Nvidia's Founders Edition RTX 5090s at all costs? Well, there are some good reasons for doing so (outrageous cost, coil whine, dumps masses of heat inside your PC case), but if you never plan to open up the card, then you shouldn't experience any issues regarding said connector.

However, [[link]] what if you want to replace the thermal grease and pads at some point in the future? What if you accidentally drop it while doing a routine service of your gaming PC? In the case of the former, it would seem that you need to be extra careful in taking apart the FE RTX 5090, because if you do damage that board-to-board connector, it's unlikely it can ever be fixed.

You might think that the latter situation shouldn't be of any major concern, but should the drop results in an impact on the PCIe connector, there's a chance that the jolt causes the little connector to break.

Third-party RTX 5090 models are more expensive than Nvidia's design, but since they're all single-board internally, you shouldn't need to worry about breaking any special connector, which you can't replace, when it comes time to refresh the thermal grease on the GPU.

Nvidia's Founders Edition RTX 5090 is a beautiful-looking design, and I have one on my desk right now to remind me of just how superb it is. But it would seem that despite its enormous power and heft, it's quite a fragile little thing inside. Maybe a quick email to Foxconn (or whoever makes the FE cards) might be in order, so that repair shops can get hold of those connectors, yes?
