[SOLVED] 750W PSU Enough?

[Vinty]

Hello,

I have a 3080 Suprim X arriving tomorrow and I currently only have a 750w power supply. Some websites online are recommending 850w but some say 750w minimum.

My PC has 2 NVME SSDs and 2 SATA SSDs and a Ryzen 3800x with 16gb of ram. If I don’t overclock the GPU, will 750w be enough? It is a Corsair RM750.
And what will happen if I don’t have enough power, will it damage the components?

TIA

You are fine.
Your psu is good enough to power it under heavy load.
"And what will happen if I don’t have enough power, will it damage the components? "
It'll bassically shut down (in best case xD ), with little chance to damage components.

I think 750 should be enough. NVidia recommends 750 and they tend to recommend on the high side. The RMX is a good unit and I would try it.

If it didn't have enough power...in general nothing gets damaged....it just may not boot...or may crash etc.

If it's not enough, the protection system on the PSU will shut the system down and reboots. Nothing will be damaged.

Don't listen to ones saying that you need an 850W PSU, they are obviously uninformed or too cautious.

The PS calcs I use show you need 613 watts. So I think you you will be ok, it looks like that card under max load could pull up to 420 watts. The Corsair RMX is very solid PS. I think you will be good to go.
