Other than its vast price tag, one thing that put off many people buying an Blackwell GPUs that takes all the guesswork out of wondering if you've clicked things in properly.
The RTX 5090 u to 150 W more power than the RTX 4090, concerns of a repeat of meltgate are more than understandable.
Fortunately, there's good news on that front. First of all, all of the new RTX 50-series cards use the revised 12V-2x6 connector, which has adjusted pin lengths to ensure that the GPU can only draw full power if the cable is pushed all the way into the socket. But if that's not enough for you, then you might want to take a nosey at what MSI's offering with its new Blackwell graphics cards (via Videocardz).
Its RTX 5090, RTX 5080, and RTX 5070 Ti cards all come with adapter cables (8-pin sockets to a 12V-2x6 connector) that sport a system that MSI has used before with some of its PSUs. Essentially, the plastic around the 12V-2x6 pins is bright yellow, so if you can see any hint of the colour after you've jammed the cable into the card, you know it's not seated correctly.
The RTX 5090 is a whopping 575 W.
Many of MSI's latest PSUs already sport this feature on the dedicated 12VHPWR/12V-2x6 cable so it's good that it's brought the system across to the adapter cables. Other manufacturers have taken more complex approaches to combating melty-there-goes-$2,000, such as warning lights for an incorrect connection, but I much prefer MSI's 'if you can see yellow, it ain't gonna be mellow' simplicity.
Whether it's enough to allay fears of pulling almost 50 A of current with an RTX 5090, through such a small connector, is another matter entirely.
