I fixed mine once. I lived in a university town, which caused the small unusual circumstance that no local store had a 700W power supply in stock, but there was a electronic parts store that had the capacitor I needed to replace. Besides the capacitor only costing 10 cents and a new one around a hundred bucks the advantage for me was that I had fixed the whole thing within na hour or two including diagnosing the issue and the bike ride to the shop. I was back on my PC that same night, and 5 years later that same PSU now well over ten years old is still going strong.
