It would be somewhat helpful if you stated what model that EVGA 650 watt is with the number they have it could be 10 or more models for all we know
if its rubbish like an NEX, G1 or GT then no its not good enough

It's a "GD" version.

 

I have 3080 suprim x 10GB i was have 650 seasonic focus gx 80 gold he normally turn of on gpu OC i change for 1300 seasonic prime 100MHz more OC on GPU.

 

My friend was testing 3080 and here is real power draw in game

if those numbers are from the wall you need to take the rated efficiency of the PSU off those numbers
556 watts minus 8% is 511,5 watts

 

Ftr if it was a "normal setup" I would have realised it was only a 600w PSU lol. But it was a build done with the Lian Li 011 dynamic case which I'm not very familiar with and the psu was tucked away where it wasn't easily visible and I had no reason to question it. I could get the compressed air in there with no need to look further when cleaning out the dust. But yeah. Pretty decent oversight on my part.

 

I'm guessing it will work if you keep the power target for the 3080 at stock levels, but you're going to want to get it out of there soon. 600W isn't going to get the job done for the next few years.

 

I was able to initially run a 3080 Ti with a Corsair RM650w when using a low power 12600 non K, but as I hadn't realized it had locked SA voltage that build didn't last long.

When going onto a 12600K I added a top tier 750w, still have use for the RM650 for my test bench which is still using a crappy CV550.

When factoring in what PSU you need for the GPU, you also need to keep in mind the power draw of the CPU, my 12600 non K I could get down to 40-45w during games with its 4.4 all core boost and a small undervolt ... if it hadn't lacked SA voltage control I'd still be using it and would have waited for 13th gen non K next.

But as it turns out I need 600Ks for the memory overclocking, which pushes up wattage, my current 13600K with overclock uses 210w in cinebench, but its using my 1000w PSU for that as it will also use whichever GPU I get next, 12600K & 1080 Ti for second system with the 750w bequiet which I still need to get around to setting up next.

 

But I'm assuming it's not a great idea to run it on a 650w due to possible momentary spikes?

Yes and it's also redlined. 3080s will go a bit over 400 W, the 3700X will get close to 100 W, and 150 W is plausible for the rest of the system. 750's the minimum I'd consider with 850 or maybe 1000 making more sense if noise is much of a concern (850+ I'd go platinum rather than gold on a noise basis). If you expect to change to higher power parts within the supply's working life that's also an argument for 1000+.

Efficiency at the operating point. Not that, for these types of questions, it tends to be all that far from rated efficiency.

Yup same thing I was thinking.. 750w min on a well made psu...

 

I know not to mix and match the cables with different power supplies but I'm not sure if I would be able to possibly keep the cables from the evga 600w + gold gd power supply, and use one of the current evga power supplies and just swap out the power supply unit while keeping all the current cables plugged in and reconnecting them to the new power supply.

I was looking at anything from the supernova g5 , p+ , ga , GM , G1 , T2 and g+

Does anyone know an official support channel where I could confirm that, or is that just more drama than it's worth?

EVGA uses many OEM´s and there is little to no cable compatibility between them
The G5 is not worth buying either its not bad just a total ripoff compared to how average it is

If you want a good EVGA unit the G6 and G7 are the best everything else other than the older G2 and G3 are not worth buying
You should replace both the PSU and its cables even if its a hassle

 

Is the Silverstone 1000w decathlon any good?

Edit : Nvm. Looks like it's ****.

A look on google came back with a result from 2008

 

I am looking at getting 1 today before everything shuts down before the Xmas period and nearly all the ones recommended are out of stock. There's a variation of the seasonic in stock but I'm guessing it's not as good? It has fdb if that's important?

There are no reviews of the FM that have done any full load testing that i have been able to find so no idea how it compares to the GX

 

I've actually found the Antec high current gamer gold 850w in stock for $204 and the MSI mpg a850gf for $174 or the MSI mpg a850G for $299. I'm guessing there's a fair difference between the 2 MSI PSU's? Does the Antec slot in between those 2 for quality?

 

The Antec is another Seasonic Focus rebrand from what i recall
As for the A850GF its not a bad option at all the OEM is CWT the same OEM that makes most of the stuff Corsair sells

The A850G is a newer ATX 3,0 compatible PSU which is why it cost so much more
Pick the cheapest option which in this case is the A850GF i have already said more than once its a good option

 

Why you search for 850W it is too expensive for you buy 1300W Seasonic PRIME 1300W 80+ Gold .From my siede its 3 wery good thing about this power supply 13900K can be OC, any gpu you buy you can use.12 years warranity.

 

seems where he is buying from cost a ton more... That would be part of the issue...

Yeah nice choice. Seems you won't go wrong with it basically being a Seasonic. I got one running now and it's almost 13 yrs old. Still going strong. About to power on my brand new 850w also. Have fun!

 

MSI uses CWT as their OEM not Seasonic
