I am seeing no significant performance difference between the 750 sfx platinum and my new 1000 watt Seasonic Vertex atx 3.0 psu at default even with power slider set to maximum in EVGA precision although the PC cable management does look sleeker now. I would think the 7700x uses more power from what I recall it was constantly hovering around 90 to 95 watts of power during gameplay vs 7800X3D at 50 watts. The only reason I tried the 750 watt psu personally because it worked with my 3090 xc3 liquid since launch, and there were not too many atx 3.0 power supplies around when the 4090 launched. I had the Thermaltake atx 3.0 1000 watt supply in my possession when I bought the 4090 but ended up returning it because the 750 sfx worked at the time.Plugging in the 7700X to my Parts Picker build, the wattage goes down to 694W. Cutting it a little too thin for my liking, but probably fine with a good PSU that can actually deliver the wattage they advertised. Platinum doesn't hurt.
Update on the pricing the 7800X3D fell to as low as $381 with Starfield game at Newegg. FYI

You're right, but that's not the point. More cores (especially more E cores) will not help gaming performance, except possibly on the very bottom of the lineup where you're going from 4 cores to 6.No. I thought RL refresh will have more e-cores? The i3 is getting 6/12.
