I've had this card for a couple weeks now - feel free to ask me any questions. I use it to get as close as I can to 144fps@1440p at the games I play, and it's been pretty awesome at that. Heads up, this is a BIG card. The heatsink+fans take up 3 PCIE slots, and I did put a little piece of plastic in my case to prevent sag. PSA - I just noticed that MD has a note about 600w being enough for the PSU. After upgrading from my old 970 to this card, my (budget corsair) 600w PSU frequently shut off my computer during high load - switching from 1080p to 1440p was enough to do it in some games. Personally, I would recommend getting more wattage if you can spare it. I'm also going to post my specs to give some context to my power usage. Asus Maximus Hero 9 Intel i7 7700k overclocked @ 4.6 16gb G.skill @3200mhzThe GPU from this drop One m.2 drive, 2 sata HDDs, one sata SSD Two case fans, and two fans on an NZXT AIO pump. PCI soundcard I now have an 850w PSU. More edits - some have said that it could have been a faulty PSU, but the part was just over a year old, and only started shutting off after I put in the new card. Im no expert on this however, so take my recommendation for more watts with a grain of salt.

InfectedbushAny overheat issues? Also, did you OC this card and was it stable? Thank you in advance.

hozhuThe card has basically always stayed fairly cool, although I did go into the aorus software and change the cooling from 'passive' to 'active' as soon as I got it installed - I didn't buy the card for it try to stay quiet. I have not overclocked the card yet - I usually don't do too much overclocking on GPUs because I try to get as much longevity out of a card as possible, and let gigabytes "Extreme" factory overclock do some work for me. If I test it out though, I'll let you know.

InfectedbushJust curious, do you have a G-Sync or a FreeSync monitor?

NightFuryI have an Asus PG279Q, which is G-sync.

InfectedbushAny quality 600w PSU is enough for 1080ti but not all 600w PSU are made equal ;) In your case it's quite likely your PSU was low quality or caps were about to burst. I has this happen to my 4 year old 1000w PSU, it was working fine until I started getting random shutdowns. In the end, swapping out the PSU solved the problem.
That said, 700w or higher PSU is of course a good idea in any case, you never know if you might need extra power down the line.

AnzialI had a CX-600m from Corsair that was about a year and 4 months old. Based on the fact that if I lowered my power draw, the PSU handled ok, it seemed to me to be a power capacity problem. I'm not expert, and I certainly wasn't breaking out any actual measurements, so I can't be sure, but if you have the cash for a higher end 1080 ti, I would advise getting a little more in the wattage dept.

InfectedbushI still think your PSU is faulty. Pascal is quite energy efficient compared to Maxwell generation, it's quite possible the 1080ti was still drawing less than your 970 at full load. In other words, your troubles came from PSU, and the fact that you changed videocard was just a coincidence.
Once again, having said that- sure, a higher wattage PSU is always advisable but by no means necessary. 600w for 1080ti is sufficient, as it is recommended by nvidia itself, and they won't shoot themselves in the foot by recommending lesser PSU than necessary because it will cause them a heap of trouble otherwise.

InfectedbushCorsair CX series is a budget line--this PSU was realistically delivering 350-400 watt at "peak sustained" operation. Its 600 watt rating is instantaneous peak power.
Corsair doesn't even make their own. They use a number of OEMs to rebadge.
A quality 600 watt PSU made by Seasonic or Super Flower will beat the pants off of a budget PSU like the CX-600m.

pqt777Thanks, that's actually good to know. I'm definitely being more careful with PSU purchases from now on, and I'll keep those brands in mind!

InfectedbushIm curious as to what your idle temps are with the card? I have mine set to auto (20% fan speed at idle) and its idling at ~53C. That seems a bit hot to me as my previous gtx 780 twin frozr idled at around 35C. Obviously nothing to worry about but it still has me curious.

flatsodaI idle in the low 30's, using the customized fan curve. That being said, I'm not even hitting 1000rpm on the fans at idle. I run games pretty hot though, near 80ish.

InfectedbushSo if my games are running around 70-75 then i should be fine

flatsodaWhile 1080ti will be fine up to 84c, it does downclock and downvolt itself aggressively when approaching that threshold. So if it ramps up to 2ghz at around 50-60c, by the time it gets to 84c, you'll be sitting around 1600hz or so, basically costing you around 20% performance. Generally, you can avoid that by using a custom voltage curve which allows you to find a sweet spot between voltage (and therefore temperature) and highest clock possible. Pascal is quite good a holding high clocks even when downvolted, so the default 1.06v at highest speeds can be reduced to .95v or so, depending on how good your silicon is.
Bottomline: look up pascal undervolting. There's a ton of guides on how to do that, it's quite easy and very beneficial for keeping your brand new 1080 ti cool and quiet, and still delivering high performance.

AnzialThat was very informative thank you!
