Question RTX 3070 my screen turns off and on

[Mielo45]

Hello,

I have encountered a problem since purchasing my RTX 3070 FE. I currently have two screens plugged in, one in display port and the other in hdmi.
Sometimes one of the screens turns off unexpectedly and then turns on again.

• CPU : i5 2500k + Noctua NF-P12
• GPU : RTX 3070 FE
• MotherBoard : ASUS P8Z68-V PRO
• Memory : G Skill F3-12800CL9 4x4Go (16Go)
• PSU : FSP hydro G Pro 750w
• Case : Cooler master Masterbox MB520
• Storage : BX500 480Go + 1To HDD
• Monitor : Dell S2721D 1440p 75hz

Do you think this is due to the new graphics card or rather the fact that my motherboard is old?

the 3070 can draw up to 400 watts, so your psu might not be giving it enough power. If you can, borrow a friends psu if you can, swap it out and diagnose

I bought my psu earlier this month so I hope I don't have a problem with it. On the other hand I do not have the problem in play but rather when I am on the desktop or when my screens go to sleep one of the screens no longer seems to be recognized I have to turn it off and on again. With an FSP Hydro G pro 750w even with a peak consumption at 450w I should not have any worries

do you have other cables that you can swap out and use?

 

[Mielo45]

Yes the power supply is modular I have other cables. What is weird is the fact that it is systematic during standby and random during use

 

[AlexTheFern]

no, i mean the dp and hdmi cables

Sorry, I did not understand. No I don't have a spare display port but I have an hdmi on the other hand. I will try to use my PC with a single display port screen to see if I have the problem and if I have no problem I will connect the second screen with another HDMI cable. I was currently watching a video the cut looks like a change in resolution or the absence of detection of one of the screens like when one of the two screens is suddenly unplugged.
