How's 9070 with 5700x3d? I'm planning to upgrade my 7700xt

u/Shaggy_One 5700x3D, 9070xt 4h ago

It's great. I play at 4k but it's not showing signs of aging. Pretty much all games run 60+ after some minor tweaks. Optiscaler makes it even better. With the recent Stalker 2 update it hits a respectable 80fps with dips to just below 60.

Once that special electrical smoke comes out, there's really no way to put it back in. They'll have to write it off as a loss

u/StreetCrzyBiteUrFace 16h ago

The smoke is the most expensive part. That plus the gasket bearings and yup, it's a complete write-off.

It worked on my machine.

What are you doing testing your code anywhere but production?

We run it on our machines!)

Worked on staging. Must be user error.

Was it local host?

u/falcrist2 7h ago

Looks like a software issue to me.

u/MarsD9376 23h ago

You don't say?

u/Cmdr_Nemo 22h ago

But hey, at least the whole front didn't fall off, because that would not be typical.

2

u/StevieMJH 16h ago

Well wasn't this power supply designed so it wouldn't burst into flames?

3

u/Cmdr_Nemo 16h ago

Well, obviously not.

Engineer here. That workbench should have a kill switch that doesn't require you to hold either end of an arc fault between your hands.

u/alokin-it 5h ago

It's shocking that he had to hold the arcing PSU to kill power....

u/davew999 21h ago

Pfft random guy on the internet here, what would you know? Put it in rice and it'll be fine.

u/123DanB 19h ago

Switch set to 120v while plugged into 220v?

Hobo here, I agree with you.

u/KGB_cutony Desktop | RTX3070 | i7 9700kF 19h ago

Can you put the smoke back in though?

u/FUS3N 19h ago

computer user here

yeah looks like it probably isn't supposed to happen

u/cyborgerian 19h ago

Hire this motherfucker right now

u/ahorsenamedjeff 18h ago

EE as well, can confirm. Isn't supposed to happen.

u/JayPeePee 15h ago

Not an electrical engineer, but I know that also isn't supposed to happen

Media designer here: I think you might be right.

u/henkheijmen 12h ago

Are you saying it isn't very typical for the front to burn off?

u/BrainYStormY 11h ago

Electrical engineer here.

I can confirm this information.

Electrical Engineer here.

Please don't grab and unplug the obviously shorting thing with your hands. Cut off electricity at the next level, e.g. power strip preferably, or if not, wall plug.

u/Debaser1990 7h ago

It's certainly not typical

u/_WillCAD_ 22h ago

You know, I don't know much about electricity, but I suspected that was a non-standard performance from that component.

It was the lights that gave it away. My lights are never that big.

u/Southern-March1522 22h ago

You mean my Exploder 4000 PSU wasn't supposed to do that? Wtf
