I'm planning on upgrading the case, maybe processor to 3rd gen ryzen once it comes out, so I was wondering If I need to upgrade the PSU to something more reliable.

Even with a CPU that has a TDP of 105, a 650 Watt PSU would be more than enough for the whole build + overclock.

And the estimated wattage usage from PCPP for your build, is too optimistic.

This build as it is, should not consume more than 300 watts from the mains.

And yes the CX650M from Corsair is a good power supply unit.

Thanks for the reply! I didn't think it would be close to 650w. While we're on the topic of the TDP do you know why the 3800x is 30w higher than the 3700x when it's only a few hundred megahurts difference? (I'm trying to decide which one to go for)

Yeah i have seen that too.

I can only speculate here. Maybe the 3800X is a better binned processor with a better OCing potential or it just has higher boost clocks across all cores vs the 3700X. And i think it may be the later.

Also take to account, that the 3800X has a higher stock clock speed as well.

And that's why it has a slightly higher prise as well.

Pcgamer lists the 3800X with a 300MHz higher stock speed than the 3700X.

Ryzen 7 3800X—8C/16T, 3.9GHz to 4.5GHz, 36MB cache, 105W TDP, $399

Ryzen 7 3700X—8C/16T, 3.6GHz to 4.4GHz, 36MB cache, 65W TDP, $329

And i say that, because the 3900X has the same TDP of 105 watts but more cores, and a higher stock and boost clock.

So yeah it's strange, isn't?

But the 3800X still hass the highest stock clock speed from all Ryzen 3000 CPUs so far.

Ryzen 9 3900X—12C/24T, 3.8GHz to 4.6GHz, 70MB cache, 105W TDP, $499

Ryzen 7 3800X—8C/16T, 3.9GHz to 4.5GHz, 36MB cache, 105W TDP, $399

Ryzen 7 3700X—8C/16T, 3.6GHz to 4.4GHz, 36MB cache, 65W TDP, $329

Ryzen 5 3600X—6C/12T, 3.8GHz to 4.4GHz, 35MB cache, 95W TDP, $249

Ryzen 5 3600—6C/12T, 3.6GHz to 4.2GHz, 35MB cache, 65W TDP, $199

I didn't even realize the 3900x had the same TDP. Its definitely strange, It will be interesting once more stuff on these chips come out and the reason for this is figured out.

Yes, there will be tests and more info about that matter for sure. :)

If it's one of the 105W CPUs, then likely yes.

If it's only a 65W one, then no need to.

thanks for the reply. Would you trust the CX650M with a 3rd gen ryzen and a 2070 as far a reliability goes?

  • 6 months ago

Yes, I would. The CX650M makes no pretense to be top of the line, but it's a very solid, well designed, mid-grade PSU.

Alright thx for the help!
