Ryzen Zen4: Are both CPU power plugs required now?

That's total system power.

Thanks for clarifying that.

Yep I realized my mistake.

GamersNexus did the same measuring 12V EPS 8-pin connector(s) and find 250W. If you ditch VRM losses from that Its below 250W actual CPU package power.
I estimate around 220W for CPU PPT at around 90~95C.

This is really neat what can be done lowering wattage and curve optimizer.

nice find. this is fucking amazing. 30 celsius saved, and basically no performance difference, at least not noticeable in real world usage.

absolutely insane.

This has been sort of the thing with most desktop processors since 8700K really. People just don't bother power optimizing their stuff

@freeagent I don't know mate, I think you should do the 7700x now after watching that video. to late to cancel your 5800x 3d order?

It’s big bucks just to slide into one.. I needed another cpu anyways for another build coming up. I will wait a bit and see what both companies do.

someone wanting to run a 7600x on the $299 steel legend mobo and a 6800 xt (entire system would pull around 550 watts) my psu is 700w evga gold rated and it is a great psu B-Tier list last I checked. got a great deal on it when it launched and only has 1 8 pin for cpu.

I could upgrade my psu sure, but if there is no need there is no need.



I must not have misread then, I remember Actually Hardcore Overclocking on yuotube on the x570 tomahawk making a comment about how nice it was that board only needed one 8 pin plugged in. so i guess i just misread his tone

700w gold evga is very good. but running 7600x with 6800xt out from 550w psu is terrible idea, just don't use psu at max output, i don't tell the 50% is a must because it's pure $$$ waste but something between 70-80% is perfect.

the 5800X3D platform overall would be still much more economically beneficial. if you are all into performance then you could get a server perhaps..

AMD blew it the moment they dropped DDR4 support from Zen 4. We're going to need DDR5 8400 kits before anything touches Bdie DDR4 in the latency department. If Raptor Lake can do 4400 bus speeds 1:1 with Bdie then the memory latency will get down to 40ns and embarrass DDR5. Samsung Bdie is literally the greatest memory ever created for enthusiasts (IMHO).
