Other than its vast price tag, one thing that put off many people buying an RTX 4090 graphics card was the fact that it had a tendency to melt its power cable if not fully inserted.
The connector has been revised for the new RTX 50-series cards but MSI has taken a leaf from its own books and incorporated a new adapter cable for its Blackwell GPUs that takes all the guesswork out of wondering if you've clicked things in properly.
The melting connector problem with the RTX 4090 was down to a number of factors: the design of the 12VHPWR socket, the shoddy quality of some adapter cables, and the fact that it wasn't easy to tell if you had the cable fully inserted.
With the RTX 5090 using up 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.
