Question issue with 1660s

[mrcrabbydude]

Recently i change my gpu from gtx 950 to gtx 1660 super and I encountered weird problem. New card only works on "prefer maximum performance" in Nvidia control panel. I can run any game or benchmark without any problem, but when im trying to change it to "adaptive/optimal power" mode, then run any game or 3d program, my screen goes for one random colour and pc freezes after few seconds. I tried to unistall drivers with DDU in safe mode, but nothing helps, also i tried few different drivers. Idle temperature on "prefer maximum performance" are 50-52, and on adaptive/optimal 37-39, so i wish i could change it to lower ones. Does anyone have any suggestions?

CPU: i5-4460

GPU: Zotac 1660s

PSU: Cheftec 700w (changed from 450w few days ago)

Motherboard: Gigabyte h81m-s2h (latest BIOS, but still from 2015)

Got a link to the PSU you're working with now?

Might be an idea to change this particular PSU ? That's a poor quality power unit, and Chieftech is a horrible brand to begin with. Changing the wattage won't help much.

Get a high quality PSU. The older PSU models from Chieftech are bad. Which model do you have ? Newer ones might be worth looking into the model and reviews first, before passing any judgement.

I know it's not a masterpiece, but i needed a budget version, at least for now (still it has 80plus,AFC,OPP,OVP,SCP,SIP,UVP specs). Apart from that my setup needs way less then 700w. Should be ok for 1-2 years (till warranty expires). Anyway i plugged in my old PSU (corsair 450w, which should be minimum for 1660s) and same error appeared only in Nvidia control panel optimal/adaptive mode. So i assume it's not directly related to PSU.

Yes, definitely NOT a power supply issue then. Btw, I didn't say your PSU is the culprit though. Just pointing out the Chieftech PSU brand's reputation and quality.

There must be something else causing this NV control panel issue.
