[SOLVED] Sufficient power supply for system

[pcmate102]

I’m looking to be getting a GPU for my old pc and I don’t know if a 500 watt power supply would be sufficient, I have a i5 2500k, gtx 770 (soon to be) and I’m looking to get a used Seasonic PSU

Used PSUs are never a great idea... especially looking at the ad, that M12II looks pretty beat up. It's also not that great in terms of quality to begin with... add that was pretty heavily used and it's definitely a no-no from me.

I'll advise getting a new unit and just avoiding used PSUs(an exception might be that it's new and at a great value).
A Corsair CX(2017, grey label) would be a great budget option and 550W would be sufficient.
