Question Best/Cheapest quality 850w platinum PSU for RTX 3080?

[Fallengod]

Looking for good quality reliable 850 watt PSU in the gold+ or platinum area for an RTX 3080.

What are the good oems these days? Super flower? Seasonic? Something under $160 would be great.

The one I wanted was the Evga P2 850 but its like $230. I am thinking SuperFlower?

From what ive heard/read the older leadex were better though anyways. Not true?

Each generation has things where the newer unit does better/worse than the prior generation.

The Leadex III has a much better fan profile, and the overall efficiency is close to what came before it.

Just my thoughts here. Reading the techpowerup review, it says it does worse in performance compared to seasonic/corsair units in similar wattage. It also has high OCP. So my thoughts, the EVGA P2 850w is older and perhaps doesnt have that because I know older superflower units were rock solid(not saying new ones arnt). And EVGA(most likely) has better customer service for RMA's and such or any issues down the line, where are SuperFlower doesnt have the best customer service.

So my thoughts were maybe go with the company I know and the SuperFlower III's are 130mm fans where as the P2 850w has 140mm double ball bearing fan. Though, I dont know what type of fan profile the Evga P2 850 has which is a wild card.

But like you said, It does say the SuperFlower III 850 gold has a pretty passive fan profile which means it would definitely be very quiet, but high OCP.

I would keep that seasonic focus plat you have FS. Should have no problem with the 3080.

I know, it just worries me a little. My logic is, I like to run power supplies close to the middle of wattage needed which is the optimal operating efficiency level normally. This helps reduce heat and enables me to hit the best efficiency levels. Even at 850, I dont think I am at 50% with an RTX 3080. My system is kind of built for silence, so operating significantly below rated wattage means it should produce less heat and not require fan to come on, like ever, which is what I am after. So I was a bit stupid buying a 750 watt without thinking first because it had a rebate at the time... and I had not planned to run an RTX 3080 either so...

That depends on what else you're running. I am going to test what my wattage is on my 3080 but on the 2080 ti it stayed below 500W for the vast majority of the time under heavier loads. That was with an OC'd 8700K.

Do you think there is any real world benefit or reason to go with a Platinum or Titanium unit over a 80+ Gold? There is definitely a price difference, I just dont know how much real world cost is saved over a year by going with platinum or titanium. Probably not much?


And thanks for the input man.

I have some Seasonic Prime Titanium PSUs. The main reason I went with Titanium is they are rated 90%+ all the way down to 10% load - others are only rated down to 50%. I have some computers that are always on and spend a lot of time at idle or low power draw.

Yeah. Smart. I want one, I just dont want to pay double the price for Titanium efficiency levels. heh.

My 750W was $170, 850W was $200 (2017). Don't recall what my 1300W platinum cost. EVGA 1600W was about $450 back then - miners were grabbing high wattage PSUs.
