Out-of-touch old gamer looking for 3090-compatible components (self.pcmasterrace)

Title pretty much tells you all you need to know about my situation. In a turn of events tonight I've been gifted a used but working EVGA 3090 card to replace my seven year old 1070.

My current system hardware specs are:

CPU: AMD Ryzen 9 5900X 12-Core (upgraded from Ryzen 5 last year)

GPU: MSI 1070

MoBo: MSI MAG B550 TOMAHAWK

PSU - Corsair CX-550 550 Watt

x4 8GB Installed Memory

I also have a 2tb SSD drive with my OS and games installed, and 4 8tb HDD for media.

My main concern is with needing to replace my MoBo with a x3 PCi board and worries about my PSU not being powerful enough. I'm not particularly worried about my tower is a Phanteks Enthoo Pro PH-ES614PC_BK.

Thanks in advance!

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.

Personally, Seasonic is the PSU manufacturer I generally recommend. Especially when you start getting over a kilowatt of rated power delivery.

The only issues I’ve had with Seasonic have been related to OCP, which just kills power to the system and then resets. Unlike some other manufacturers like Rosewill, Silverstone, or the generic manufacturers that used to be included with cases where a power spike on either end has killed a number of other components, including my Pentium 4.

But my Seasonic PSUs have generally held up fine, even during XOC type situations. Such as a modded GTX 780ti and an FX-9590 with LN2 pots.

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.

the corsair power supplies are built by seasonic- at least the higher spec ones.

if you had a 500w or lower unit though you might have gotten some of their older import junk.

[–] Kumabear 3 points 11 months ago (1 children)

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.
