Possible to find new psu for Orion P03 640?

Hi.

I was thinking about a rtx 4070 later for this computer, but i see it require a minimum 750watt for this card.
Is it space enough to easily find a 750w that fit this model?

Also Wonder about the standard 500w that it comes with, this model have been delivered with rtx 3070 and nvidia say it require 650w? So seems like the stock one could be a bit underpowered for the 3070? :-)

The largest ATX12VO PSUs we know of currently are 500W, so the only option for a larger supply is a hack. There have been people who bought a larger old style ATX PSU that has a powerful single rail +12V, then modified the connectors to use only that voltage from the supply. There are adapters from the 24 pin ATX to the 6 pin 12VO available though you need to be careful to match the pinouts. Your system would need that 6 pin, two 4 pin and whatever the GPU needs, all 12V except the PS_On in the six pin.

Thanks for the information, sounds too advanced for me so i must just keep it as it is, working perfectly for me now in gaming but question would be for how long it last, how quick the gaming world goes up in requirements. Should get a couple good year out of it still i guess?

Likely by the time you really need a new GPU, you'll want to upgrade the system rather than just the GPU. I expect the 14th or 15th gen chipsets will be out by then. :)
