[SOLVED] PSU for 3080

[Misiekq]

Hi, I have a 700W 80+ bronze PSU with power efiiciency higher than 85%. Will it work for cheaper versions of 3080 like Ventus 3X?

What is the exact make/model of that powersupply?

The psu is meh, not the best, but not the worst.
MSI recommends a 750W powersupply, but you could probably get away with a good 700W good one.
Hmmm.
Idk what to tell you.
The psu isnt bad, but its not a top of the line one, its on tier C on this list, which doesnt mean it should be really paired with a 3080.
What is your budget for a new one?
Dont expect to buy a good one below $100-$125.
I heard about SilentiumPC, i've been eyeing their Signum SG1V EVO TG ARGB case for a while.

Well, my friend is using exactly the same PSU for Gigabyte 3080 without any problems. I think I'll buy 3080 and not use 100% of it because I dont need it. Do you think 700W will be enough for arround 80% usage of 3080 power?

The fact that your friend uses it with a 3080 with no problems, means nothing. It can fail at any time.
If you can afford a 3080 you can afford a decent psu to pair it. I would not trust a mid tier PSU with a top of the line gpu.

If you plan on undervolting the 3080, why even buy it?

I found that out the hard way : )

As you're asserting that the 3080 is running on the PSU without any problems, could you share the readouts you and/or your friend got with a 3080 at load, which are necessary to make such a determination? The 3070/3080 can be very power spike-y, to a degree that otherwise OK PSUs can sometimes fail (like the FSP-made EVGA PSUs). It would be useful to have information if this PSU is handling the transients well.
