Rtx 5090

[Xj2000]

Hello everyone,

I have an RTX 3090 GPU and was hoping to upgrade to an RTX 5090 for 4K gaming. However, I was about to order one (stock is slowly appearing), and I came across an article about the melting connector. After researching online, I'm quite concerned. I upgraded my power supply in February to a Corsair HX1200 ATX 3.1 in anticipation of the upgrade (the card isn't cheap; some saving time was needed). I'd like to know everyone's opinions on the issue. Is it likely I might be affected, or has this been blown out of proportion, with factors like third-party cables not being considered? I would be using either the Corsair connector or the 4x 8-pin adapter included with the graphics card. I was looking at the Zotac 5090 Solid as it seems more reasonably priced and is in stock. I'm seeking something that can play games comfortably and hassle-free at 4K with the highest possible settings.

The 12HPVR/12v6 standard isnt great as there is a low (1.1 to 1.14) power tolerance for headroom compared to other standards.

On top of this from the 3090>40/50 series the card bundle multiple power inputs into a single output and this means the card - through design decisions - cant really tell natively if one of the wires is passing more current than another to compensate (in the event of one random factors like wear and tear, basic oxidation on the connector or actual user error). Actually Hardcore Overclocking has a great video explain the nuance of this.

For most people they will plug it in and they will never have an issue until they replace the card/cable but others might find issues that should never exist in consumer electronics - include some wires getting hotter than others because of the above. Debauer EN has several videos on how this can occur.

Ultimately, if you are undervolting your card you are less likely to get to a scenario where the sustained amps on one wire will ever be concerning enough to cause heat enough to begin melting but at same time JayzTwoCents showed plugging in a brand new cable perfectly can somehow still result in less even amp distribution that if you intentionally tugged it so it wasn't tugged it half way out...

You milleage will totally vary...

You're not going to get anything other than our opinion/hearsay here I'm afraid. Only the PSU & graphics card manufacturers know and they're not going to tell us.

I'd have a watch of the videos suggested above, der8auer and buildzoid (Actually Hardware Overclocking).

As @Tetras says, have a look at the investigative videos on YouTube and make up your own mind in relation to the perceived risk. Personally, I think the design of the 5090 is flawed ( wrt power handling ) so I've decided to sit this generation out. For the price they're demanding I expect better engineering. But I already have a 4090 FE so I'm not exactly struggling with performance in 4K.
