I have a 3090.

Don’t get a seasonic to run it.

Most especially if it’s a duel 8 pin 3090.

I went through a prime ultra 850 (fair as it was being pushed)

Then I got a prime 1300w and it still had issues in very high gpu power use games like metro exodus.

In the end they had a sale on Corsair axi1600 and I got that and it’s been stable ever since.

This is incorrect.

I believe this was true far in the past.

Most of the high end stuff from Corsair are OEM,d by flextronics.

You are absolutely fine except for the power supply.

I’d recommend avoiding a seasonic as I had issues with their OCP on two of their power supply.

I like the Corsair AXi series. They allow you to adjust the OCP if needed.

If games apply it in context as an immersive effect I’m ok with it if it’s not over done.

Like when I’m looking down a scope or something, or through binoculars.

Games that apply it as a full screen effect I turn it off immediately.

The game I have found that pushes power use the hardest for testing real world cooling and power on video cards, is Metro exodus enhanced. (Awesome game also which is worth the bug anyway)

It consistently uses nearly 80-100w more than anything else I have seen.

Pushed my modded and watercooled 3090 to 600w at which point the power limit I set there held it. Even at 600w it’s power limiting down nearly 80mhz below normal full load clocks.

If the card pulls more than 300w I personally wouldn’t be using a daisy chain.

You will probably still be fine on a card with three plugs across two cables.

It’s worse on cards with two plugs, like some of the 3090 and 3080 cards. That use 400+ w of power.

Please as much as your power supply allows you to do so, do NOT daisy chain them on a high end modern GPU.

Use dedicated cables from the power supply for each of the 8 pins where ever possible even if it means a little more cable clutter.

Also not to scare you or whatever but I would personally avoid using a gigabyte power supply if you can at all avoid it.

Power supplies are the heart of your computer, while I understand it can be a sad thing to have to spend good money on, potentially limiting the amount you have to spend on more fun parts like cpus and gpus. It really is worth it in the long run. A good power supply will usually get me through 3 seperate builds and still be under warranty for the start of the third one.

I’d recommend something from be-quiet or from superflower as good options that are fairly affordable at least in my market tho mileage might vary.

Other good choices are Seasonic, and the upper mid range and higher Corsair (HX and up)

it’s a thing.

Yes I hate it.

I think it can be disabled in bios.

Everything is probably fine.
