Description:
More reports of the cable melting on Nvidias flagship graphics card are rolling in, unfortunately for those owners.

FULL STORY ======================================================================

Nvidias RTX 4090 graphics card looks to be getting a third-party adapter which is built with a right-angled design well explain more in a moment
from a major power supply manufacturer, as the card suffers further reports
of melting cables .

Yes, unfortunately there have been another two reported cases of melted adapter cables with Nvidias official solution that hooks up the RTX 4090 to
an ATX 2.0 power supply, as Toms Hardware reports . Which brings the total up to four incidents, with Nvidia already having said its investigating the
first report which reached the companys ears.

The purported problem is with the 16-pin connector that needs an adapter (4 x 8-pin to 16-pin) to hook up the RTX 4090 to an ATX 2.0 PSU (as opposed to an ATX 3.0 product, models fresh on the scene which can directly use the 16-pin connector).

The problem is that its difficult to fit that adapter in many PC cases, with it having to be bent round at a sharp angle and the pins not being seated properly as a result has been seen as the most likely culprit for these alarming instances of cables melting.

The theory is that having a right-angled power connector one that can more easily fit in the PC case without having to be jammed up against the side panel (or close to it) will mean less strain on the connector, and less likelihood of it not being fitted properly to the 4090 graphics card .

This solution is what Seasonic is apparently ushering in, as seen on Chinese forum Bilibili, a post which HXL flagged up on Twitter (again via Toms Hardware ). Add your own seasoning as ever with sources like this. Seasonic

Seasonic isnt the first company to have had this particular brainwave, as you may be aware. Cablemod has already aired its 90-degree angled adapter solution, one thats supposed to be available for pre-order come the end of October.

We dont yet know when Seasonics take on the right-angled adapter for the RTX 4090 will arrive, or indeed if it will remember, this is info pulled from Bilibili, so we should regard it with a great deal of caution. And the Bilibili poster further notes that its just a sample product (in the comments), so we dont have any confirmation it will be realized.

There are other caveats here, too, with these kinds of third-party adapters. Remember that Nvidia does not allow for the use of anything but the official adapter with the RTX 4090 and turning to an alternative will void your warranty . Thats a serious issue right there, of course.

Some folks are also arguing that its not the cable angle, as much as the fundamental design of the connector itself which is the real problem in dealing with the wattage which can be gulped down by the RTX 4090. (Considerably more than 450W with spikes in power usage, particularly if
youre looking at overclocked custom models of the 4090, naturally). But if that connector isnt up to the job, surely that would be something Nvidias testing wouldve uncovered or wed hope so, anyway.

And if the problem is one of seating the connector, the most prominent
theory, surely a right-angled adapter would at least help somewhat in terms
of mitigating any tension caused by having to bend a stiff cable around?

All of this is speculation at the moment, though, and we need Nvidias
official word on whats going on with these worrying cases of cable melt, naturally. Hopefully thatll be forthcoming soon enough, and equally we can hope that we wont get more reports of this problem coming in from other RTX 4090 buyers as if that reality comes to fruition, well, obviously thatd be very disappointing.

Meanwhile, AMD has been quick to confirm that its next-gen RDNA 3 flagship, which is on the verge of being revealed, will not use the same style of power adapter as the RTX 4090.
