Possible to use 7 year old PSU to check new components?

I am building a new gaming PC and I am still yet to receive a PSU (M12 EVO 750W). Tomorrow, I am going to buy a cabinet from my nearby computer market which is actually not so nearby. There is also a MSI service centre in that market and I have bought a MSI H81M-P33 motherboard with i7-4790k. But I do not hope that the motherboard will be able to run a hashwell refresh processor out of the box as it will need its bios to be updated. So I can take this motherboard to the service centre and ask them to update the bios, if needed.

I have a Core 2 quad system which is being powered by a local made PSU from 6 years without any issues.

So my question is, can I use that PSU to just check whether this motherboard can run i7 4790k or not? So that I can take this motherboard to the service centre.

(I know the answer would be no, but just confirming) :P

These are the output ratings.

    Just took a snap. These are the specs (in the OP) and yes, it has a 24-pin connector for mobo and a 4-pin connector for processor.

    that should work fine. the voltages are all good and it should have plenty of watts

    I just don't wanna fry any of the new components. Although the PSU has not given issues in its life. I hope it works fine for just an hour or two on a 4790k.

    if the psu works there is almost no chance of hurting your components
