You're better off moving this thread to the
Mining Support or
Altcoin Mining section for help with a PSU- this section is about services, but they're typically not mining-related here.
Do NOT replace the blown capacitors with random ones from a laptop charger. That can only cause more harm than good (to your PSU and possibly miner if it's hooked up to one). Following the troubleshooting guide won't do anything because you already know the cause of the PSU not working- you'll need to either replace the capacitors or buy a new PSU.
