Re: blows fuse with no load

Sure sounds like your power supply has a short and should be replaced.

Is there any fuse inside the KH624 power supply?

Typically, there are no fuses inside these devices. You'd think that there should be - but it's not the case. Most of the time, power supply units (PSU) begin to overheat and ever so slowly die. Replacement PSU have dropped in price - like everything else. Your best bet is to replace it and maintain it from here on in to ensure a long life.

PSU's overheat and fail because of dust. Lots of it. The fan inside blows air into the PSU case to help keep the component cool. Unfortunately, dust gets blown in at the same time - and slowly builds up on all surfaces and components. The dust build up acts as a thermal insulator that prevents the air from removing the heat. A PC on the floor will have a great deal more dust build up inside than if it were on a desk top. Oh, and the fans in the PC (not just the PSU) blow dust all over the motherboard components and expansion cards inside it, too. The most expensive components are the CPU and video card(s).

Move the PC to the desk and regularly clean the components that have fans on or near them ideally with a vacuum or if unable to vacuum - blow out with compressed air to keep them running reliably.

Dear Guru my power supply of my computer with model enp-2120d doesnt work no power output so please gave me some idea or schematic diagram,thank you.

Do not try to fix this power supply. Better to replace with new or good used. I see many on ebay from 13.50 to 25.00. Also google that model for other options. Most likely fuse on the power supply has failed but if you bypass the fuse, with jumper wire or another fuse, will blow again. Probably capacitors. Good luck

Power inverters can do this if they are internally shorted or they are being over loaded. If you are just using it to charge a phone or a computer it should not be over loaded. Now if you are charging a computer and running a small cooler at the same time, that may be real close to max which may blow a fuse. Have you tried hooking it straight to the battery to see if it will run what ever you are running. It has it's own fuse so if it has an internal short it will blow that fuse. It if works hooked to the battery and is just blowing the cig lighter or acc. fuse it can be a weak socket. If the socket is hot it may have a loose wire on the back side causing low voltage which can blow a fuse. So hook it to the battery direct, if it works ok there, reconnect it to your acc port and if it is getting hot it may be the weak socket. If it will not run hooked to the battery, it has an internal short and it would be better to buy new than try and fix. Sorry.

450W ATX SMPS of Intex

sir all smps can be reapired using indian jugar technique. first of all see twi diods under the burnt transistors check them they are short then check the capacitors if they are not leaky or pregnant then see bridge reactifier change all that looks short or open then replace all and the transistors with 13007 transistors(jugad) be careful that 13007 must be isolated from heat sink that means metal part must be fixed to them but not short to them . replace the fuse with 2 ampere fuse (for safety) ..... have fun

Computer wont turn on

big blue flash! I would say one or more of the filter capacitors just blew up! time for a new power supply. the AC goes into the unit and a surge suppressor is across the line - looks like an orange colored disk - from there it goes to a step down transformer to a multiple output secondary. on the secondary there are numerous "bridge rectifier" circuits that take the AC and change it to usable
dc. That DC is filtered with large capacitance capacitors. I have a site if I can still find it that has large wattage power supplies. I'll find it and get back to you.

A new power supply will fix your problem, and when the fuse blows do not replace it. It blows to protect your computer. please replace with a new power supply.
