Hi All,
I thought I would do some testing with a plug power monitor to see my total system draw as I currently have a 650w PSU and was wondering if that would be enough in my current system to support a RTX 3080. So below is my spec and my various power measured at the wall during various tasks + stress tests:
Ryzen 3600 @ 4.4GHz - 1.26v
16GB 3600MHz CL16 - 1.42v
MSI B550M Mortar
2 x NVME 1 TB HD's
RX 5600XT (mild overclock as you can barely overclock them)
EVGA 650 GQ - 80+ Gold PSU
Below is the total systme draw from the wall/plug:
Idle - ~55W
Internet Browsing - 90W
Call Of Duty - Warzone - ~245W (Graphics card was 145W)
OCCT "Power" Stress (whole system) - ~ 360W (Graphics card was 190W)
So even looking at a worse case scenario with a 100% all core load on the CPU, it looks like my 650W CPU will be enough for an RTX 3080 assuming it consumes 200W extra and the measurements are at the wall so likely to be 10% lower load on the PSU.
So this post was not only to report my findings but also to get some clarification to confirm that my 650w power supply has sufficient headroom to cope with an RTX 3080 in the current system. Though I am planning to upgrade to a Ryzen 4000 most likely in the new year which may require a new PSU.
