Power supply Match for 3080

[FAHEYGF87]

I'm looking to upgrade from a 3060 to a 3080(non Ti), I'm sure my current 550w isn't going to be enough, but how much do I really need?

 

Current Specs:

3060(Non Ti)

2600x(OC'd to 4.0)

Noctua NH D15

16gb 3600

(1) M.2 SSD

(1) 200mm case fan

(4) 140mm case fans

I usually reccommend a quality 850 watt psu for a 3080 for 100 guarantee that there won't be a power off due to transient spikes.

Something like this would be a good option

Run my 3090 with an evga 850. Only see 550 from the wall. Gpu isn’t fully utilized with the cpu being subpar.

What CPU are you running? Maybe I can keep my 550w for a while and upgrade later.

9900k. Doubt a 550 has the amperage needed on the rail to support the card at anything more than idle.

In terms of minimum, I'd say a quality 850W that can handle the spikes properly. That said, I would probably at least get a 1000W just so you are in the higher part of the efficiency curve more during load + having a bit more wiggle room.

 

But you don't have to do that.

Some 3080s draw more power than 3080 tis so it is best to get to know the difference in the cards. 

The range is from 320 to 400 watts stock so what card you pick may influence your PSU choice.

I like these videos for comparing cards.

 

I picked 1000 since I had issues with my 2080 tis and 850 PSUs. Using 1000 watt PSUs fixed the problem. 

I am sure that it was something to do with the motherboard, GPU combination but it was cheaper to replace the PSU than the other parts.
