How to minimize power consumption, while running vpn server?

Hello, this probably isn't a question that gets asked often in this forum, but I don't know where else to ask it.

I have VPN server installed on my home PC and VPN client on my laptop. I'd like to leave the server running while I'm away from home and connect to it from my laptop at any time. This would mean that my home PC would have to be on constantly, since its motherboard is an older model that does not support WOL (Wake-on-LAN)

My question is, what would be the most efficient way to run my home pc? I don't want to pay huge monthly electricity bills, just because I left it running for 2 weeks straight. I know I can't turn on sleep mode, because that would mean that the VPN server would stop functioning (as well as the remote desktop app). Are there any Windows settings I can configure for minimum power draw?
I've looked around the Windows 10 advanced power settings, and one setting in particular caught my attention: Minimum CPU power state, that defaulted to 5%. Are there any ill effects that would occur if I set this lower, say 1%, or even 0%? And would that help with the power consumption?

Thanks for reading, I'm anxious to hear your responses! :)

Easiest question ever!

Install it on raspberrypi or orangepizero. It takes less than 1W.
I reach 5Mbit/s up/down with orangepizero

I thought about this too, but how do I turn my main PC on without wake-on-lan?

Oh, sorry, I guess I omitted this detail in my post.
What I'm using the VPN for is to connect to my PC via remote desktop. So it will have to be on for that purpose.

then use old mobile phone to wake up your PC with server on it

just left it sleep and when you ring the number you turn it on for definite time...

Interesting, can you link me a guide as how to set this up? I tried to google it, but only found people using an android app and wake-on-lan.

If you are still not able to make it ask someone else to do it for you.
You need to interface ringing from mobile phone to push button on pc to wake up

It can be simple mobile phone, not android

Or use SIM800L module with arduino nano, when sim800 sends "RING" to arduino just close some relay paralell to the push button on pc

Total price well below 10usd
