Older psu

[bris]

I am about to built a new comp in the near future. I will be using an X570 motherboard with a ryzen 5 3600, 16gig 3600 ram and at first will have my rx 580 in it until I can get a rx5700x eventually.

I currently have two slightly older power supplies one of which I am hoping to use.
One is a Cooler Master 600 watt green power RS-600-ASAA currently in use now
the other is a very little used Cooler Master G650M which has basically been unused pretty much since it was bought.

Would either be suitable for a new build of today.
Thanks

1st is 15 years old antique with more like 450W rating by modern standards.
It also has those artificial current limiters in 12V making it bad fit for power hungry graphics cards...
Even if lack of 8 pin PCIe power wouldnt' be problem.

While definitely not good that G650M is at least better than first.
Though capacitors are from cheap grab bag and wouldn't consider it long endurance PSU.
