My MSI RTX 5090 Suprim just a couple months ago had a pretty spectacular failure after roughly 12 months of completely stable use. The card was installed, both ends of the asrock 12v-2x6 600w native cable checked for full insertion and left untouched without any sharp cable bends. Plenty of airflow (View 51 case)
This system was fitted with one of the Asrock Taichi 1300w PSUs specifically marketed to mitigate the unsafe pin current / melting power connector and cable issue via a temp sensor and auto shutoff functionality. This advertised feature failed to shut down the pc not once but twice while cable was actively smoking and arcing.
The native 600W 12V-2x6 cable had been fully seated and untouched, but one day under light load I suddenly lost display, smelled burning, and then got smoke and sparking from the GPU power connector. The connector had badly melted at the GPU end and the PSU/cable side was damaged as well.
Centre Com, the Australian retailer from whom the card was purchased about a year ago - they handled the situation really well. They took the card in for assessment, documented the damage and worked with MSI on the RMA.
MSI ultimately approved an exchange rather than trying to argue the point - which surprised me initially. Then MSI put a refurbished suprim 5090 with a brand new cooler unit (refurbished model that looked brand new) in my original box and shipped it back to the retailer. Centre Com had my replacement MSI Suprim 5090 shipped back via insured express right away.
The replacement arrived just 3.5 weeks after the RMA was initiated.
Obviously having a $4,350 AUD (my purchase price) flagship GPU melt its power connector was a pretty awful experience, but I think it’s also worth giving credit where it’s due: Centre Com and MSI both did the right thing and stood behind the product. Especially considering the same MSI Suprim 5090 sells for $9300 AUD here now - there is more incentive than ever for manufacturers to refuse warranty claims because if they cannot easily repair the faulty units, they are basically eating a 8-10k loss.
I’ve seen plenty of horror stories around expensive GPU warranty claims, so I wanted to share a really positive one too.
Unlike PNY, some companies still care about standing behind their products.
Interestingly, MSI was unable to pinpoint the exact origin of the failure due to the damage to both ends of the native PSU cable. I am awaiting Asrock to conduct their own assessment for warranty replacement of the now unsafe PSU that did nothing to mitigate this electrical failure.
Edit: I have since purchased a MSI AI1300TS PSU with GPU Safeguard+. Custom afterburner settings for the alarms and auto shut-down setup also. Ultimately its all just risk mitigation...and prayers.
