Choose Your Cables Wisely
As per Igor’s Lab, the RTX 4090 uses a cable manufactured by either Astron or NTK. The latter has a better latching system and an audible click after insertion. In contrast, Astron’s design differs from the specified standards. Igor claims this may be a production error thus explaining why such a case is rare but still possible. In fact, after rigorous testing, it was revealed that NTK adapters have lower resistance even after being plugged in and out 10 times. Don’t take our word for it, this has been showcased by NVIDIA themselves. Igor’s Lab posted an exclusive chart highlighting the difference between both brands. The test below basically shows the resistance after x number of cycles (connects/disconnects).
Who’s at Fault?
Many experts have given their opinion about this new adapter fiasco. JonnyGuru claims that this issue is due to the user’s own fault, although others have conflicting opinions. Gamer’s Nexus theorized that 150V cables, used by Igor’s Lab were the main cause. To prove this, he tested a 300V cable and could not reproduce the failures Igor’s Lab faced. (Chart via Igor’s Lab)
Conclusion
All in all, it’s high time for NVIDIA to step in and give an official clarification regarding this problem. Whether it be a slight modification or a new cable altogether, it is of utmost importance. Besides, to save itself from the hassle AMD decided to drop out of this new ‘Gen 5 power connector’ bandwagon. All such accusations are harming Ada’s sales because at the end of the day who would want a broken RTX 4090 and $1599 less in cash?
