So I have a quick question for other owners of the 3080 ti (not the xc3). From reviews it was pulling 4-500w but mine only goes to 360w in furmark, games and other tests. The tdp is 350 and it runs great so I'm not worried, just curious as to what's going on. I'm not daisy chaining cables, I have three separate evga ones plugged in to the card. They are the Y cables but I'm not sure if that matters. I also have a 1000w evga psu and if it matters the oc switch is on. Any ideas?

1) Have you switched to the OC BIOS, and 2) have you maxed out the power slider in either PX1 or MSI Afterburner?

At max power limit, the card will typically draw about 25w under that limit. Or 425w. This is about what all the high power cards do under a good 4K load. It takes a Furmark type load to average near or at the full card power limit of 450w. Peaks can be over 450w but you need GPU-Z on .1s refresh and run for a while to detect them. If you aren't seeing this, you may be cpu limited gaming at a lower res, lighter games, or have a power imbalance issue. Stock TDP on the 3080 Ti FTW3 is 400w and max is 450w, btw. I like using Furmark at 2X MSAA and a +90 or +120 overclock to get a good power draw. You can check for power imbalance with HWiNFO. Make sure to run X1 and get firmware update on a new card.

To me it sounds like your OC PL is NOT being applied. Do you have a spare HDD or SSD you can throw windows on to test?

It's more efficient to use clean power and not daisy chain your cables especially on the 3000 series GPU's. On previous generation cards it was doable because there wasn't such a huge power draw. There is a risk of daisy chaining with the 3080/TI/90. I've read that some of them can fry the card and your PSU.
MY OC was excellent on my 3080ti FTW. +130 on the core, but the power draw was ridiculous going over 450w under load at times but it was stable. The fans were running around 85% which is too annoying. I decided to under-volt because that much power makes me nervous. I'm getting nearly the same performance under 300w under load, far cooler temps, very low noise levels, peace of mind and the bios switch is set to OC. Use clean power by not daisy-chaining.

Actually it's more dangerous to daisy chain the two plugs on a 2080 Ti FTW3, as they can easily pull 300w combined and sustain it. If you daisy #1 and #3 on a 3080 Ti or 3080, it will be under 250w, peak.

A PCI-E connector that follows the basic standards with 18 AWG wiring should safely be able to take 288W at a minimum, no problem. https://forums.evga.com/FindPost/3165934 As for what you can daisy chain, the answer is a little more complicated than that. - 2-Pin card with TDP at 350W and under, you'll probably be fine daisy chaining assuming you didn't screw up any contact
- 2-pin card with TDP greater than 350W (375), two deidcated
- 3-pin card, one dedicated, two daisy chained is fine
- Avoid all the above, dedicated for each plug always and you won't have to worry about anything
There are people with certain power supplies where I understand they don't have a choice but to daisy chain a 3rd pin. As long as the wiring is 18 AWG or larger, you should be fine. Lastly, go visit the 3090 threads where they talk about their cards dying. Many of them are "but I had dedicated cables to each pin!" I haven't seen any correlation with higher failures daisy chaining 2 pins on a 3 pin card. I've seen many 3090s with 3 dedicated die also.

How do you undervolt this card? Had an issue where the system powered itself completely off mid gaming. Was pulling 375 watts. Must have been a power spike because I have a 1000kw Seasonic Prime. Thanks

lol, nope! There was already a super long thread trying to find causality. No correlation to the number of connectors/daisy-chain and card death. The majority of responders did nothing 'wrong'. We know the cause. Cheap parts, bad design, and high power limit. EVGA and NVIDIA share blame, but it's EVGA's fault for trusting that the cheapest design allowed by NVIDIA pushed to the highest power limit allowed by NVIDIA (and above), would survive. Average-based power limits ensure current spikes will occur. The majority of deaths occured between menus and cut scenes and real load. Zap those weak VRM with a spike, and dead. No amount of PSU cables will change that. Don't you have something better to do with your time? How many more posts do you need to make before you can put that link in your signature that you are just itching for?
