How safe is the 4*8-pin adapter for the RTX 5090

[loustan2000]

I just got my RTX 5090, but my HX1200i, although ATX3.1 certified, does have native 12vhpwr. The GPU came with a 4*8-pin adapter. I know that the RTX 4090 had problems with melting cables, so I'm wondering how safe the new adapters are with the new 50 series cards?

 

I've set the power limit to 90% on afterburner as a precaution, just to be on the safe side

Yes, it does? Just use the native cable. 

 

Or do you have the old HX1200i from 2013 with the blue label on the side?

The PSU came with this 12vhpwr 12+4-pin cable, but there's no 12vhpwr port on the PSU itself

How the PSU side of cables looks does not matter. By that logic, the PSU has no native SATA cables, native PCIe 8 pin cables, or a native 24 pin cable either. That cable is a native 12V 2x6 cable, regardless of how the PSU side looks.

So is the 12vhpwr cable provided by the PSU safe to use with the RTX 5090, or should I just continue using the adapter provided with the GPU?

Its safe.  Or, as safe as the 12vhpwr cable can be with a 5090.

This whole situation is just hilarious. People have been using official adapters and there has been melting, 3rd party PSU provided cables and there has been melting. We simply cannot tell you that you're not going to have a problem.

 

The risk is on you, the user, knowing full well the situation prior to making your purchase. If you're using a high quality PSU that provides 12VHPWR directly, that's an official and acceptable form of powering your card but that DOESN'T mean you're in the clear, that much is clear from the history on this topic.

Is the 12vhpwr PSU cable any safer in particular than the adapter that came with the GPU, or do they both carry pretty much the same risk? The adapter is a 4* PCIe - 12v2*6 I believe.

 

I'm going straight from a 2070 to a 5090, so haven't had to deal with any of the new cables/ power standards yet, so the information is much appreciated.

Is it a 5090 FE?

The connectors are most faulty on the FE cards, so this one should be fine as long as it's securely connected.

TL;DR, you're fine. Multiple people have said it's fine. 

 

[loustan2000]

OK, guys, thanks for the help and info. Much appreciated!

This is not accurate at all. Where are you hearing this?

Indeed I heard the opposite, its supposed to be the FE cards where the adapters were redesigned to put less stress on the socket.
