dual PSU power

[AleXXL]

I was wondering. I have a Gigabyte G292-Z20 server with 2 2200W PSU on it. I plan to use it for AI work, so I will put some RTX 3090 GPUs on risers and use it like this. Can I count the PSUs as 2x2200W, meaning 4400W in total or they work togather just for redundancy and I should count them as just 2200W?

if run with redundancy no. without, yes.
if you can't configure the PSU unit to non.redundancy mode, you have max. 2200W because one PSU may fail without shutdown.

I do not think there is an option for configuring PSUs. They are already configured, I assume. This is what that say on their web page: G292-Z20 (rev. 100) | GPU Servers - GIGABYTE Global

not the PSU itself, the whole unit.

not the PSU itself, the whole unit.

of course, I checked in bios and BMC and there is no such thing.

yes. it is redundant only. 1200W( 100-127V ) / 2200W( 200-240V ) max.
