How are people with 3000 series cards faring with PSU usage?

So, in the middle of a Doom session today and my PC froze for the first time since I got the 3090. No obvious reason but perhaps replacing the PSU is a sensible thing to do as it's 6 years old and it's probably on the limit in my system. Quite difficult to find a decent 850w PSU that isn't out of stock so went for this one as it gets decent reviews and is actually available to buy!

Did the Windows event log capture any sign of the issue?
 
Some PSUs are now so good they can output +135% power, meaning you don't have to have the headroom, it comes with headroom, and it delivers the power on the label forever* (*until it gracefully exits).

I expected a lot of blown psus with these cards

Not many PSUs would be "blown" if overloaded. Decent PSUs have overload protection which shuts down the power supply if it is loaded beyond safe limits. Obviously there will be a few cases of PSUs going "pop", simply because they develop a fault. It's true that a heavily loaded PSU is slightly more likely to fail, especially if it is old, or is poorly designed.
 
Have been tracking my new 3070's power consumption (Ventus 3x) - averaging about 220 - 230w. Only about 10 watts more than my OC'd 1070ti.
I was a little concerned as I only have a 600w power supply but its been absolutely fine, although I will probably leave it stock as I doubt I have much head room for over clocking.
 
My RTX 3090 FE is making my 3 year old HX1000i whine/buzz loudly under load. A 2 month old HX750i has the same problem.

Idle: 170W
Peak: 460W (SteamVR Performance Test)

CPU: i7-7700K (at 4.2GHz)

GPU configured as "Prefer maximum performance"

Google it. Seems like a common issue. I once used a (cheaper) Corsair PSU in a build for a customer. Had to replace it due to coil whine.
 
KFA2 SG 3090 + 3600x
PSU is a Corsair RM850 I've had since 2013.

Was drawing 510w at the wall when messing about on Watchdogs: Legion with everything on max. Nothing is OC'd.
Gaming at 1440.

As I type, 230w... I think people will be fine with a decent 650w PSU.

My 1080ti would draw 400w with everything maxed out (obvs no RT or DLSS)
 


OCCT burn on Power mode. CPU fully loaded + 3090 Fully loaded

MAX 560W psu is pulling

93% efficiency right in the sweet spot.

for refrence my old Vega56 with overclock on 64 bios would be in the same ballpark.
