Question Seasonic psu's and rtx3000 series cards question

I just got a 3070ti and am needing a psu upgrade. I'm looking to go 850w to be plenty safe. I've seen alot of people saying stay away from any seasonic made psu with the rtx 3000 series due to shut offs randomly. I see nzxt makes some nice psu but I guess there seasonic as well, and evga I guess uses superflower on some of there psu.. anyone got a suggestion for an A tier 850w psu that plays well with rtx3000 series. Thanks

You don't need an 850W for the 3070ti. a 750w would be plenty. Even a 650W would probably be fine.

I don't know who those people are, seasonic is one of the best PSU makers. I've owned a bunch now and rarely had issues.

Asus and Phanteks are re-branded Seasonic. Some EVGA are too.
 
Yea idk who they are either but it's all over the net about seasonic and rtx 3000 cards but whatever I guess. I know the nzxt c and e series are seasonic made if I'm correct .. would one of those be ok?
 
I don't know about all this "don't use Seasonic with RTX 3000" business. In regards to wattage, I've seen a lot of stuff saying that you should get 100w more than traditionally suggested because the 3000 series tend to "spike" their power demands. I think the suggestions were 750w for the 3070, 850w for the 3080, 1000w for the 3090.

Since the 3070Ti is closer to a 3080, 850w is probably a good choice.

I have a Seasonic Prime Titanium 750w. Looks like they are called "Prime TX" now.


Here are all the Seasonic PSUs with 850w variants.

 
Yeah, I think this is related to rapid power spikes that would trigger OCP in some Seasonic PSUs. Seasonic had the same situation with smaller PSUs with the release of Vega 56 / 64.

It seems like their OCP continues to be very sensitive compared to some of the other industry PSUs, but personally I continue to use them with confidence. If there's an issue, you can always RMA.
 
I have a 850W and a 1000W Seasonic Prime power supplies. They've both got 12 year warranties. Probably will never need to use it. I've still got a 7 year old 860W Platinum and a 12 year old 850W Silver. All going strong.
 
My PC Power @Cooling 500 watt just is like the eveready Bunny -- it keeps on tiocking...going on over 15 years...lolol

The only reason I retired my Seasonic designed and built PC Power & Cooling 750W PSU was because I moved to a smallish ATX case and needed a shorter, modular PSU. But it lives on in a friend's PC. 13 years and going. 11 of them in my PC.
 
I'll take a seasonic any day. Still have a 1kw seasonic platinum that I'm using in a spare system. PSU is pushing close to a decade, still going strong.

Just built a new rig, got a phanteks revolt dual system psu now, seasonic made. Honestly, will probably use seasonic for life, as long as they aren't sold to a third rate company that destroys the brand =P.
 
Its an old thread but I wanted to add that the RTX 3000 cards especially the 3080/3090 cards seems to have high transient spikes in power consumption which caused psus to shutdown even in good Seasonic/EVGA models >=750W.
Nvidia seems to have fixed the problem with a new driver since last year.

Nvidia RTX 3080 crashes are reportedly fixed as new GPU driver lowers boost speeds

But the drop in speed is a very minor one you won’t realistically notice

+1

i have a 1200W Prime Seasonic, and a RTX 3090 + 1070 GTX as a secondary display.
I have no random shut off's.

Seasonic makes one of the best PSU's.
The only other brand i would even consider over my Prime is the Corsair AX which is also made by seasonic, unless its the 1200W version made by flextronic.
 
I want to make an update...
I have random shutdowns in Amazon's New World.

Here is my post over at EVGA forums:

EVGA 3090 FTW3 Ultra
Seasonic Platinum 1200W SS-1200P3

Everything works fine until i open new world, and put settings to medium.
Once i have it on medium, the PSU trips overvoltage protection, system reboots.
I can not get into the game anymore after that.
Each time i load the game, the GPU will trip my PSU's over volt protection.
It ONLY happens when i lower the settings, and not keep them on VERY HIGH. (i know its irony here)
I need to use EVGA Precision to lower the power to 50% reduce my core clock -200 and ram -600 to get back into the game.
Then i need to set the game back to VERY HIGH on all settings, and then i can reset the gpu back to default.

So i am wanting to put this PSU on the do not buy list, or caution list, unless someone else who has this psu can comment that its just mine.

I ended up getting a EVGA SuperNova 1300W P+ today.
I will swap out PSU's and see if it solves this issue.
But it also seems that @sze5003 also has the same issues with a seasonic.

If your running a higher end 30 series, i would not recommend seasonic psu's at this moment.
