[SOLVED] POWER SUPPLY REQUIREMENTS FOR EVGA RTX 3080 XC3

[jack.h.tierney]

So I was planning on upgrading to the RTX 3080. Here is my current system Here is my current system.

I5-9600K with an EVGA AIO Cooler 240mm
16 gigs DDR4 at 2400mhz
Samsung 970 EVO 500g NVME SSD
Samsung 860 EVO 500g SSD
EVGA RTX 2070
Asus Prime B360m-a motherboard
4 case fans
Case is a Cullinan MX so plenty of air flow

My power supply is only 650 watts but it is a good one. It is the seasonic focus gx-650, 80+ gold fully modular. I never overclock or anything like that. I know they recommend 750 watts but I feel like that might be overkill. Will I be ok with my current PSU if I upgrade to the 3080?

Overclocked 9600k = almost 200W@5ghz
3080 = around 350W
Other components =100W to be safe.
This makes peak usage around 650watts. So i don't think 750W is an overkill. Rather it's probably the safest minimum for overclocked systems.

But I will not be overclocking at all. The CPU or GPU

Still, unlocked i5 9600k can take upto about 120W. And even if you don't overclock the GPU, it'll come factory overclocked by EVGA and may take upto 320-350W.

RTX 3080 requires 100W more than the RTX2700 you're using. And you gotta leave a little headroom when buying PSUs. Seasonic 650w might be able to run it. But it'll be almost under full load while gaming.

Ok thanks! Maybe Ill save the 200$ on GPU and 100$ on PSU and just get a 3070. Then use the extra $ for a PS5 lol

Yeah. 3070 is safer to run on 650w PSU
