1000 G6 or 1600 P+ for 4090?

[mazeroth]

I have an EVGA 1000 G6 (Seasonic) I purchased about a year ago for my 3090 build. I'm in the process of piecing together a new build for a 4090 (waiting to see 13th gen Intel; i7 max) and I picked up an EVGA 1600 P+ about 2 months ago in anticipation of these 4090 monsters needing huge power supplies. EVGA had it for $199 - 10% associate code, so $180.

After seeing the reviews, how the transient spikes are less on a 4090 than a 3090 Ti, I'm contemplating selling the 1600 P+ and just sticking with my 1000 G6. I'm thinking I can at least break-even on the sale. If I were to use the 1600 P+, I'm thinking I could get $80 tops, locally, for the 1000 G6, so about $120 out of my pocket if I keep the 1600w monster. Or, keep the 1000 G6 and I have $120 more in my pocket.

The 1600 P+ seems to not rate as well as the Super Flower based P2's, being an FSP power supply, but I'm sure it's still fine.

What would you do?

Given the way things are heading, I'd personally keep the 1600w unit for peace of mind. On the other hand, if you want, you could wait for ATX3.0 version units and bypass all of the confusion regarding the new 12VHPWR connectors....

Sell what you have and buy an ATX 3.0 PSU. You'll thank me later when you see the lack of cables needing management.

I went this route myself, and will be installing my ATX 3.0 power supply when I get some free time.

1000W will be enough unless the rest of your system is power hungry. I wouldn't worry unless you're running a heavily OCd 13900k and also want to do a heavy OC on the 4090. But that's an edge case, most people will be fine with 1000W.
