Thank you for your prompt response. I grasp your explanation regarding the VRM and concur with your assessment. While they should handle elevated temperatures, I'll bear that in mind. Unfortunately, I cannot acquire the heatsinks—Amazon doesn’t ship to my location, and a courier would be necessary. Tomorrow, I will utilize an alternative power supply and provide an update afterward.
However, there’s a concern I have. I believe the graphics card is experiencing excessive heat and that it may be transferring this warmth to the Northbridge (I believe this component, based on online research, is located at this point: https://imgur.com/cxBnqkK). Given the size of the 1080 Ti and the minor protrusion on the Northbridge's heatsink, I worry that contact between the card’s backplate and this component could cause temperatures to rise rapidly, potentially reaching 120°C. As far as I understand, the Northbridge is involved in communication with graphics and PCI-E interfaces. Do you believe this could be the source of the black screen issue? Could it even be that the Northbridge is the cause of this problem?
I’ve located a motherboard with a compatible socket (1155) – the Gigabyte P67X-UD3-B3 – which I intend to use to investigate whether my current board has any underlying issues.
This appears to be an exaggeration, but as I mentioned previously, the simplest method for pinpointing the source of that 120°C temperature is to allow it to reach its maximum heat and then assess the warmth of different components by touch. You should be able to identify which areas are hottest. However, I would recommend performing this check only after replacing the power supply unit.
A GPU backplate functions as both a heat dissipation device and a strengthening element; furthermore, the perimeter of this plate is rarely the warmest area. In fact, if it were to contact the Northbridge heatsink, it would primarily function as a supplementary heat spreader for removing warmth from that component. I believe your concerns about this are excessive.
I apologize for the delay in responding. After replacing my motherboard, which proved ineffective, I shut down my computer and removed the power supply unit. Now, I’m seeking your guidance once more. There are two sellers offering two suitable power supplies in my area—both are brand new and unopened. I’m uncertain which one to select, particularly given your expertise with gaming power supplies. I have a slight preference for the EVGA model, but I’m still unsure.
-Thermaltake Toughpower Grand RGB 850w 80+ Gold
-EVGA Supernova 750w G3
I would strongly recommend the EVGA Supernova. It received a high rating of 9.8/10 from JonnyGURU, based on his review located at https://www.jonnyguru.com/blog/2016/12/2...-supply/6/.
I appreciate that. I will retrieve it and investigate to see if the problem continues.
If virtualization technology - display driver is activated within the BIOS, it should be deactivated to resolve the issue of persistent black screens.
This is because enabling vt-d can cause drivers to unexpectedly shut off the monitor.
The system information indicates an Intel Core i5 2400 processor.
I installed the power supply unit today, and the issue hasn't reappeared yet – thank you all for your assistance. I believe the primary cause was consistently the power supply unit itself. The persistent blank display has now been successfully fixed.
I’m uncertain of your location, but Newegg recently emailed me about the 650 and 750 Supernova power supplies, priced at $67 and $87 respectively. That’s a reasonable deal considering they are gold-rated PSUs with a 10-year guarantee. Joining their email list to receive promotional offers is highly recommended.
