Do I need to upgrade my psu?

Do I need to upgrade my PSU for the new 2080, I currently have an EVGA 550w G3 PSU

[JoshCanHearYou]

Yes you would have to, unless you are using like a cpu that is superlow power but considering its a 2080 probably not. I got 550w on psu calc so you should prbably go for 650-750w

It's dependent on your CPU as well as the RTX 2080, assuming a 2080 will do 250W TDP.

I'm using an i7-8700k not overclocked

Weak.

 

Just kidding, 8700K + 2080 seems like you would need 650W at least, but don't quote me on that since I'm not the greatest at estimating PSU sizes.

I wouldn't necessarily say you HAVE to, but its probably advisable.

 

They always recommend a higher PSU than strictly necessary to account for the fact there are good PSUs and bad PSUs that can't reliable operate at their supposed rating.

I'll just wait until they come out to see what will be best to upgrade to

No. Like every single GPU/CPU computers ever, you will be fine with a 450W PSU. You don't need to upgrade.

Wait and see.  If the card uses about the same as a 10-series card, I doubt you'll draw more than 450W from the wall.

 

My overclocked 5930K and 1080Ti draw just a little over 400W when I stress them both at the same time, and I can imagine that my old CPU is a lot more power-hungry than a stock 8700K

You could power a GTX 580 and 1920X on a 550W PSU. OP is fine. Unless the RTX uses triple the power of the 1080 then OP will be fine.

Don't upgrade. Your 550G3 is what I would recommend to someone shopping for a PSU for a 2080 and 8700K that they plan to overclock.

 

An 8700K and 1080 would use about 350W overclocked.
