The MSI RTX 5090, one of the most powerful GPUs in the market, is facing an alarming problem: melting 12VHPWR connectors.
This issue, primarily due to a design flaw in the power delivery system, has been causing significant damage to both the GPU and the power supply unit (PSU). With the RTX 5090’s power consumption reaching nearly 600W under peak loads, this problem is intensifying, leaving many users concerned about the long-term reliability of their expensive hardware.
In this article, we’ll dive into the root cause of this issue, how it affects users, and what you need to know before investing in such high-end graphics cards. We will also provide practical advice on how to avoid this problem and what alternatives exist.

What’s causing the 12VHPWR connector to melt?
Many high-end GPUs now come with a 12VHPWR connector, which is meant to effectively transfer power from your PSU to the graphics card. It is not without problems, though.
One significant design issue in the connector is that it can only handle high power loads through a small number of contact points, which leads to overheating of the cable and connectors.
The plastic around the connector melts when the temperature rises above acceptable bounds, which can occasionally surpass 150°C. This could result in irreversible harm.
According to a recent user report, this connector issue caused serious damage to the MSI RTX 5090 and the PSU.
The wires melted, leaving noticeable bulges and charred pins on both ends of the connector, even though a high-quality Corsair SF1000L PSU was used.
Even if the GPU is not overclocked, this problem still occurs, which aggravates consumers who have spent hundreds of dollars on their setups.
What Effect Does This Have on Your Hardware?
Possibility of Long-Term Damage: Both the GPU and the PSU may sustain significant damage if the 12VHPWR connections melt.
Your components may sustain irreparable damage from the overheating, voiding warranties and raising the cost of replacements.
Safety Issues: These connectors’ excessive heat generation raises safety issues in addition to hardware ones. Plastic insulation melts at temperatures higher than 150°C, which may cause short circuits or, in the worst situations, fire dangers.
Financial Loss: Purchasing a top-tier GPU, such as the RTX 5090, is a significant outlay of funds for many users. A melted connector could cause a large financial loss because the GPU can cost up to $2,900, especially if the problem isn’t covered under warranty.
What’s causing the overheating of the 12VHPWR connector?
The connector’s design is the primary issue. The 12VHPWR connector is made to withstand a larger power load than earlier power cords.
However, excessive heat buildup results from the way electricity is channeled through a limited number of pins. The load transfers to a few contact points if the connector is not placed correctly, causing the wires to melt and overheat.
Ways to Prevent This Problem
Although the fundamental design flaw has not yet been officially fixed, users can reduce the risk by taking the following actions:
Use Higher Quality Cables: If at all possible, use third-party cables that are designed to more effectively manage larger power demands.
Keep an eye on the temperature to ensure that your system is properly cooled. Controlling the GPU and PSU’s temperatures is essential to preventing these kinds of problems.
Avoid Overclocking: While overclocking can boost performance, it can also increase the power load on the connector. Avoiding overclocking can reduce the risk of overheating and connector failure.
What Are the Options for MSI and Other Manufacturers?
This serious defect in the 12VHPWR connector must be fixed by the manufacturers.
They might, in particular, employ different techniques for power supply or modify the connector to better manage high power needs.
Although switching to a 12V-2×6 connector in more recent designs may be beneficial, it is not a comprehensive fix because the fundamental problem still concerns the cable’s capacity to support such large loads safely.
Does the MSI RTX 5090 Present a Danger?
Despite being a gaming and performance powerhouse, the MSI RTX 5090’s ongoing problem with melting connectors is cause for serious concern. It’s crucial to understand the hazards if you intend to purchase one of these GPUs.
Even if the issue might not impact every machine, it’s still a serious one that could result in major hardware malfunctions.
For the time being, users should think about improvinghttps://marcopolosports.com/whatsapps-latest-update-improving-user-experience-by-simplifying-chat-list-filters/ their cables, making sure their systems are sufficiently cooled, and refraining from overclocking.
For a possible solution, follow MSI and other manufacturers’ updates. The 12VHPWR connector’s future is still up in the air, and high-end graphics cards like the RTX 5090 may continue to suffer from this issue.
1. What is causing the RTX 5090’s 12VHPWR connection to melt?
The tremendous heat produced by the high power load, which is concentrated on a few pins, causes the 12VHPWR connector to melt. The GPU and PSU are harmed as a result of overheating and plastic insulation melting.
2. Is it possible to stop the RTX 5090 from melting?
Yes, you may lower the danger by using high-quality cables, making sure your system is properly cooled, and avoiding overclocking, which raises the temperature and power load.
3. Can the melting problem be resolved using the 12V-2×6 connector?
Better power distribution and more dependable contact are provided by the 12V-2×6 connector, but the design issue in the 12VHPWR connector is still there.
4. Will my damaged RTX 5090 be replaced by MSI under warranty?
If your RTX 5090 is damaged, MSI will often provide an RMA (Return Merchandise Authorization). However, if the design error is not fixed, the problem can return.
5. How can I keep an eye on my GPU and PSU’s temperatures?
To make sure your components stay within acceptable operating limits, you may monitor their temperature and power consumption using software such as MSI Afterburner or HWMonitor.
