Rtx 2080ti advice

Hi everyone, firstly apologies if this is in the wrong section of the forums. I have posted regarding this before I believe but was unsure on how to find the thread.

Onto my question. Will my 750w power supply support an upgrade to a 2080ti FE from a gtx 1080.

My system currently sits as the following except I've added the 2080ti inplace of the gtx 1080 on the power calculator link

Any reassurances in going ahead with this would be great or advice against if the case may be. Thanks.

Is it a PCS build with a Corsair PSU? If so, then yes.... it'll be fine.

Hi yep it's a PCS build currently using a Corsair 750w CS series 80 plus gold modular ultra quiet. CPU/RAM overclocked. Based on my power calculation (link above) not sure if overclocking the rtx is doable as well as at load it was already at 620w roughly out of 750w.

Spec is below

CORSAIR CARBIDE SERIES™ AIR 540 GAMING CASE
Overclocked CPU
Overclocked Intel® Six Core i7-6850K (3.6GHz @ up to 4.3GHz)

Memory (RAM)
16GB HyperX SAVAGE DDR4 3000MHz (4 x 4GB Kit)
Graphics Card
8GB EVGA GEFORCE GTX 1080 FTW GAMING - DVI, HDMI, 3x DP - GTX VR Ready!
1st Storage Drive
2TB Samsung 850 EVO 2.5" SSD, SATA 6Gb/s (upto 540MB/sR | 520MB/sW)
2nd Storage Drive
2TB WD BLACK 3.5" WD2003FZEX, SATA 6 Gb/s, 64MB CACHE (7200rpm)
1st M.2 SSD Drive
512GB SAMSUNG SM961 M.2, PCIe NVMe (up to 3200MB/R, 1700MB/W)
DVD/BLU-RAY Drive
NOT REQUIRED
Power Supply
CORSAIR 750W CS SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET
Power Cable
1 x 1 Metre UK Power Cable (Kettle Lead)
Processor Cooling
Corsair H100i V2 Hydro Series High Performance CPU Cooler
Thermal Paste

Thanks for both the replies so far. Thanks for pulling up the tech power article aswell. I suspected the overclock may push it a tad far. Looks like I'll stick to the founders edition and shall leave it at stock in this case until future upgrades. As everything including your recommendations suggests it'll run healthily.

Might depend a bit on the 2080 ti
https://www.techpowerup.com/reviews/MSI/GeForce_RTX_2080_Ti_Lightning_Z/30.html

If you're looking at overclocking an RTX 2080 ti with 3 8-pin power connectors it could get a bit dicey with CPU and GPU both under very heavy / torture loads. But a less extreme 2080 ti without overclocking would be easily fine in your current PSU.

Do you think minus overclocking at this current moment in time I could get away with going for a 3rd party card under the same PSU as they tend to draw a tad more power.

If I was to ask what would everyone else do go with a founders card or spend 50 pound more for this one.

Not sure how that calculator is working but I genuinely wouldn't worry about it. Even worst case scenario with 400w ripping through the GPU I would still stand by a 750W Corsair PSU doing fine and dandy.

GPU - 400w torture
CPU - 150w torture
HDDs, USB & Accessories - 70w with everything drawing the max current all at the same time
Cooling - 25w kicking the shirt out of it

Corsair PSUs will handle what they say (plus a margin I may add, they are fantastic PSUs) and the fact that you're never in a million years going to be running under those conditions, I would happily run even the craziest 2080ti in your system with a 750w PSU.

I'd have agreed entirely with the above, until I saw:
https://bit-tech.net/reviews/tech/intel-core-i7-6860k-broadwell-e-review/5/
apparently with a system with an OCed 6850k pulling near 300W in Prime95 (total system).

Usually the PSUs are more forgiving than the rating, but still, that'd be pushing it well past my comfort zone.

All synthetic loads ofc, Prime and Furmark, but I've seen AC Origins do some pretty brutal stuff in terms of CPU load so I wouldn't chance an OCed 2080 ti Lightning in there too personally.

Mind you if one were spending £1400 on a GPU or whatever the Lightning and EVGA Classified tier overclock-oriented GPUs cost, with an OCed HEDT platform, why don't have you have 1200W+ Platinum PSU anyway ;) That'd be kinda pocket change by that stage.

Plus the water/exotic cooling.

Anyway, the PSU shouldn't bat an eye at most 2080 tis at stock.

That's absolutely insane. I would never have thought that in a month of Sundays :D

I knew they could push 200w if really going for it but I never thought 300w was on the horizon, even with the other bits n bobs.

Still, that's just a crazy scenario and he would still have 50w up his cuff.

Wow, i knew once I'd purchased this system forum members pointed out the 6850k is on the toasty side and therefore pumps the wattage somewhat. Luckily I would of thought minus running benchmarks gaming should leave me in a strong position still.

Scotster earlier on you posted above with the 400w torture post and the CPU etc. Do you think knowing what oussebon has posted it would still be fine to pick any 2080ti at will? I was looking at the evga 2080ti ftw 3

I've also looked at some build guides from various YouTubers and they are using 750w PSU so this certainly backups everything that has been posted so far?

Personally I wouldn't worry at all. The situation where you would get near 700w power usage is going to be purely synthetic and you would need to be absolutely hammering everything. The 400W power usage was with a particularly high power 2080Ti, I've not actually seen anything higher than that (or approaching that figure). This is all completely worst case scenario and, coupled with the CPU, will not be close to normal gaming utilisation.

If, by some extreme circumstance, you found that the power utilisation was higher than expected, you could upgrade the PSU. Again IMO, the chances of this are nill.

Get it all together, max out the CPU/GPU with synthetic load testing and see what your power usage is with HWInfo. If you see 400w on the GPU and 300w on the CPU it's time to be concerned :D


Edit: FTW3 limit is 373w but you need to push REALLY hard to hit this figure. There's another 25w of headroom for you :D

Appreciate all the replies and reassurances. I notice scotster in your forum signature that you have a similar if not superior system setup and are running a 750w so seems like nothing to hestiate with regarding upgrading.

I don't have a Ti in place, which is considerably more powerful than my piddly 2080 :D

I wouldn't hesitate in putting one in my system though :)

Edit: IF you have any issues I'll swap you :D
