Question Sapphire Nitro+ RX 7900 XTX PSU Requirements

[Mingusus]

Hi forum

What PSU do I need to run the Sapphire RX 7900 XTX Nitro+ with an i9 14900K?

Will my current Corsair RM1000i Gold from 2018 be sufficient?

For a high-end system and components, it is time to update your PSU. Do you have a budget in mind and source for making a purchase?

I was hoping that my current PSU would be sufficient (I am currently running my PC with a rtx 3080).
Would a Corsair HX1500i be a good PSU choice?

Yes, but really overkill, in terms of wattage.

Your current PSU would most likely power the system reliably, but I do feel that if you're spending this much on a new GPU, it may be worth upgrading to something new as age can derate PSUs.

Hx1500i will work fine if you can afford it

You don't need to replace your RM1000i that came with a 10 year warranty. That PSU is totally fine for your setup and you can use it for a couple of more years. Replacing about a year or 3 is early enough except if you upgrade the GPU to an upcoming high-end nVidia that needs two 12v-2x6 pin connectors.

Hello Mingusus. A seven year old 1,000 watt PSU is more than sufficient to power your 14900K build with a RX 7900 XTX. By the way, I also contacted Corsair support on behalf of your inquiry, and they agree with my statement above. Happy gaming my friend.

FYI: Your RM1000i appears to be covered by a 10 year warranty:

While @--SID-- and @rcald2000 may technically be correct, consider this. PSUs do degrade over time, that is a fact that none here will deny.

If you are spending the kind of money you are to build a high-end system with new components, one of those should be a current PSU.

You may be fine , as is, but why accept the risk? Keep your current PSU as a back-up device and get a new one would be my advice.

Thanks for all your replies .
I am not building an entire new PC BTW. I am just upgrading my GPU.
I think I will keep my current RM1000i PSU for now and replace it in a few years time.
