Depending on how adept you are at dealing with electronics, you might consider popping the power supply open and looking for burnt NTC thermistors. An NTC thermistor is a device that is used as a current inrush limiter. When you plug 120V devices into 230V outlets that is often what goes first. If there is a fuse that may have gone as well.
NTC thermistors are both common and cheap and if you have an old dead
ATX PC power supply you probably have one in there already.
But yeah, the power supply is most likely the problem and a replacement is definitely worth a shot. It's possible you can fix the power supply yourself too though if you want to take a look. In these cases it's often possible to see parts which have literally burnt making it easier to identify the problem.
EDIT: (A disclaimer of sorts)
And please remember to use common safety guidelines when working with AC connected devices. A new power supply is probably the cheap and fast way to go for most people and almost certainly reasonably priced on-line but if you're interested in learning about power supply repair I recommend the topic and the NTC trick is one that has saved me a few times. I learned about stuff like that from resources like DiodiesGoneWild, (Amazing!) ElectroBoom, BigClive, PostApocalyptic Inventor etc. There are so many great electronics resource out there these days and that's more the nature of this question than for an electrician. Good luck and play safe.
Here is a typical-looking one in a photo on Amazon

On an ATX power supply you will often find them near the part where the AC lines are going into the board before the big capacitors.
In this photo you can see a pair of blue NTCs on the bottom left corner right between the fan and the bridge diode.
