First build.. What PSU should i get?

[FunkyFresh]

Hello. 

For ryzen 5600x and rx 6800 xt <or> rtx 3080 build..

If i'm looking right at psu list they are from "A" list, one of the best psu's?

What psu would be better? I'm looking at Gold or Platinum from "Be Quiet Straight Power 11"

Is there big difference in gold versus plat?

And what wattage sould be safe to use?

Thanks for helping. <3<3

Moved into its own topic, you can edit the title if you'd prefer something else.

Thanks. I simply din't want to make another "will or will not" post. But hey it's alright.

I would say they’re both pretty good if they’re on the A list. A platinum PSU will use less power when on idle. When you say 5600 & 6800xt do you mean both at the same time?  Depending on the price difference and how long the thing spends idle you may actually make up the additional cost in power savings over time.  As to what the differences are between the two as to its internal structure I don’t know.  If it’s going to spend a long time with the 5600 alone but be big enough for a 3080, I might go for the platinum just to waste less power while I wait.  Again depends on the power cost, PSU price difference, and time spent with only the smaller GPU.

I have had good luck with Corsair and EVGA PSUs.

From the A list a Corsair RMx model in the wattage range you need (850?)  is a good choice.

I have a 750W RM from about 8 years ago still going strong in a build my daughter is now using.

cpu - 5600x

gpu - 6800xt

I just don't know which psu would be better over all. I wan't the best of best.. My old pc is ~8 years old fx8120 gtx 660..

Im finnaly upgrading and with PSU i'm stuck. I don't know which would be best and what Wattage should i get.. I don't plan upgrading for atleast 8 years..

Where i read people say 750w also? Isn't it overkill?

Ah.  My understanding is that power efficiency rating has little to do with quality, so being platinum doesn’t make the second PSU more reliable, just more efficient. I don’t know what they did inside the thing to make one gold and one platinum.  My suspicion is the designs are fairly similar, but I know nothing.  With an 8 year life cycle the power savings of the platinum amortized over that amount of time could be significant though. 
 

My move given available data would be see what the price difference between the two is, divide that by 8, see how much power that buys, and see if the more expensive one might actually be cheaper over time.  There is also the possibility that power prices will increase in the next 8 years so there’s that to consider as well.

30$ difference. Not much in 3000$ Build.

Corsair RM750X also has two different models.. One with 135 fan, other with 140 fan? Which is better?

Black/white vs Fully black label.

They're both excellent, still the one on the left (2018 version) is better (significantly quieter than the 2021 version on the right).

To break even the platinum would have to save $3.75 a year in electrical costs. Seems doable, which would make the platinum one perhaps fractionally cheaper over time. Suspecting the 2018 is the gold and the 2021 is the platinum which would make the gold one quieter.  A bit strange, because that electrical efficiency difference would change to heat making the gold one fractionally warmer.

Apparently, the Gold and Platinum PSUs OP was referring to are bequiet's Straight Power 11 Gold and Platinum.
(All versions of Corsair's RMx are 80+Gold)

Since you're planning to keep your system for the next 8 years, you don't need to oversize the PSU for future upgrades.
Efficiency is irrelevant, as it does not indicate how good the PSU actually is.

For a 5600x+3080 combo, a high end 750W PSU should be more than enough.
The RM750x is a great one, and usually one of the best bang for the buck units out there.

Let us know your budget and where you will be buying from (U.S.?), so that we can help you choose the best available option.

I live in EU. Can get any psu.. Price wise by wattage (750w), most units - same price. Gold ~150 Plat ~170-200 Euro

Isn't 750w like i said overkill? My plan was getting 650w originally.

Where exactly? Or can you point me to the store link where you want to buy the PSU?

This is the best value for money.

Okey, i selected 3 that i like the best. And are from "A" tier. (Made voting poll)

Be quiet beeing cheapest.

If you put a 3080 in it? imho no.  I don’t know what suggested power is for a 6800.  What gpu you have has a very large effect on what wattage you need.  

[FunkyFresh]

Will go Be Quiet.. They got better looking GPU wires. Each plug has own wire..

Not like Corsair who has two plugs on one wire.. Making big loop of fat wire next to GPU to connect next plug in.

The two plug system can work as well IF the cable is thick enough to handle double the draw.  You may or may not be getting anything with the be quiet as the two cables could both be connected behind the wall of the box.  Would just effectively mean the extension wire was longer.  I don’t see how it could be worse though so you may have a point. 

[FunkyFresh]

They are connected at PSU side, simply "longer" extension for each plug. No loop at gpu.

So potato potato (or tomato tomato? ‘Potato’ has a tech meaning these days).  The question then is is there enough power at the base?

Yes thats where im not good at.. You tell me.

Will 750w do for 3080 or 6800xt (same power draw ~300-350w)

If i use one plug that goes > to two plugs at gpu

[Bombastinator]

Tempted to go 850w and use only 3&4 for the gpu.  1&2 have the same output as 3&4 on the 550w for the 750.  Possible that if the 750 works on 1&2 you could use the 550.  It’s not the only thing that uses power so there could be other problems.  What I don’t know is how many amps are actually needed per though.  That’s the big question and one I don’t have an answer for.  Someone else might though
