Got a 490W or 650W PSU. Looks like the CPU is probably around 9-10 years. I'd say probably not much. I bet it's idling would be around 120-200W depending on # of disks, disk type, and if your using the PCI slots.
For reference I'm running 4 Intel NUC11i7s, $400/unit bare metal, 64GB ram (2x32) $120-$130, and the most expensive part is the flash storage I am buying to fit my needs. Power on these are like 10W idle and max is like 60W each when using turbo.
do you think that this thing would be around 150W?? I think more about 50W Max, for example the cpu is relatively low-power
For comparison, I run a thinkstation p300 with i7-4790 (TDP 84W) 24/7 and the power usage looks like this:
Even when idling this old processor still guzzles 45W. Certainly not as nice as GP's that only use 10W during idle.
hummm... yeah that's a bit power hungry

They have some measurements from their machine though depending on GPU and CPU at least it'll probably be higher. Also, if your hosting stuff 24/7 your CPU load won't be 100% idle so you certainly would be higher than it depending on what you host.
Do you think it would be better to go to an consumer cpu instead of a xeon?
Server CPUs are built for the workload (hosting / background services) rather than desktop applications for consumer PCs. That being said generally your going to be more limited in disk / ram than CPU unless if you have some specific needs.
In my setup, my server resources are averaging 10% cpu, 54% memory, and ~70% storage. I'm running 4 PCs, 8 cores each so 32 cores, currently on memory I got 2x64GB and 2x16GB so 160GB ram. Between CPU and RAM I am utilizing basically 3.2 cores worth of processing and 86GB of ram. Most of my ram is going to postgres databases for speed improvement and it takes off load from the CPU.
ok
I am not the best at estimating power usage but like I said depends on the configuration it has. That's just CPU, not including powering everything else so it's idle load will be higher. RAM, disks, type of disk, amount of disks, GPU or other PCI cards, etc every additional component adds to the idle watt usage.
for sure but even with all my stuff I think that something like that would draw around 40-50W idle and up to 90W running
