What's going wrong and what can I fix it?
It feels like recently to me. The cost gap between a solid 750-watt unit and an 850-watt one can be around $40 to $50. That's not a huge deal by the numbers, but it adds up for many people buying budget gear. Mid-range power supplies and high-end low-wattage options have more of a similar area of overlap than before. My main problem with current advice is all the new ATX 3.1 power supplies that still don't have reviews or teardowns yet. It's like walking into a minefield where you can't tell which model names are real and which ones aren't. Regarding short bursts of extra power, relying on protection might be okay? Letting the PSU dip slightly below 100% duty cycle could handle those spikes safely. Choosing a unit that is bigger than any possible spike means you risk getting less efficient during normal use because you're just sitting in the idle space. I've never heard anyone investigate this from that angle before. Older power supplies did allow for short excursions beyond 100%, but they couldn't handle the longer runs required by new large GPUs. Seasonic Platinum units had serious problems with RTX 3080 and 3090 cards, even though those were often 850W or 1000W models. The Overcurrent Protection (OCP) kicked in way too soon, causing the power supply to shut down unexpectedly.
No other PCIe slot to try, so that is about it. If you can get ahold of another GPU to test with, you can confirm the CPU/Board are working correctly. Particularly if the 1080 Ti works in another system.
I had the same thing happen before. It turned out to be a faulty video cable.
Thanks for the suggestion! But I've checked the HDMI cable too (and tried another one with my laptop acting as a second screen). No weird stuff happened during those tests either. Since different cables and monitors gave me the same result, it's likely not about the monitor or the connection/ports on either side of them.
Yes, I tested the system with another, already working GPU, and everything ran perfectly. That means the problem is definitely not my GTX 1080 Ti. Thanks for the great advice on the PSU too! I'm going to swap this power supply now for a Super Flower Leadex VII before trying other GPUs. This should make sure my system stays cool in the future. Thank you again! Finally, could you recommend a good card to replace the GTX 1080 Ti? I don't want something super new or very hot; I just need a card with similar performance that's already here, needs less cooling, and won't slow down my CPU. Here are your computer specs: CPU: Intel Core i5-12400F Motherboard: MSI Pro H610M E RAM: Corsair Vengeance LPX 32GB (2×16GB) at 3200MHz Storage: WD Black SN770 1TB NVMe SSD Monitor: Samsung Odyssey G3 24-inch
Money is your biggest limit. Those cards are about the same speed: RTX 4060, RX 7600, or RX 6600 XT.
If you can find an Intel B580 for around $300 or less, what do you think?
