Seasonic Focus Plus Gold 850W problems with dual gpu build?

Hello

 

I currently have a Seasonic Focus Plus Gold 850W with a very heavily overclocked 970. Im upgrading to R5 3600 and 3rd party 5700xt for 2k gaming. Because I use 2 monitors for GPU heavy work, I will keep the 970 and connect it to a 1080p monitor. Peak power should be around 650W so the 850W PSU shouldnt cause any problems. I read some articles about the Focus Plus Gold having problems with 2 GPUs, are these problems still occurring ?

Older SeaSonic Focus units are known for having issues with high-power graphics cards. When did you buy your PSU?

Keeping the 970 is likely to cause problems, not the power supply. Nvidia drivers are awful when they detect AMD drivers installed. Not to mention you will not be able to use cards from different manufacturers, generations and cores together. It simply wont work or the system will be a slow mess.

Why would you want to keep the GTX 970 on the system? what kind of heavy work?

 

You're only asking to have drivers issues with both nVidia and AMD running at the same time and I don't know why you need the GTX970 to drive the 1080p screen.

Newer ones too , if you,re talking about them shutting down under high gpu transient load , just that people will have to learn the hard way when ripple damages their gpu...

Blown out of proportion here. I've yet to see a Focus Plus damage a card or system.

Maybe , because the revision has only been out for a year?

You'd need absurd amounts of ripple to damage Vrms on a card..people forget we used to use diablotek quality power supplies 10 years ago without issue ?

Still yet to see a site test this with an oscilloscope. Mostly fan boyism at its worst.

2 k freesync gaming on the 5700 xt and moderately gpu dependant 3D rendering on the other. 970 can handle it. I probably just exchange cards with my collegue, he got a oc rx 470, should do the job as well.

About 4 months ago, so I'm clear then ?

Most likely, yes.
