Question about Antec SL300S 300W Power Supply (045176) 300-Watt Power Supply

1 Answer

Diesel engine power supply

The fan on the power supply was making a loud noise like a diesel engine taking off...well now my computer won't start at all. I'm assuming it is the power supply that has finally broke. Do I have to put the same Antec SL300S power supply in? I've never changed it out before...are they all standard with the same cables? What do you recommend?

There are power supplies that will work with your machine made by other companies. The wattage is whats important.

Noisy


The noise could be from dust that gets in cpu fan or power supply fan. Clean them but do not open the power supply. Better replace your power supply.

Computer acts like it in standby mode will not power up, made a weird noise according to my daughter and quit


Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this will help

Alienware aurora desktop with 525 Watt Power Supply was working fine then all of sudden started making a loud noise like it was going into overdrive or something then emitted a horrible like burning...


The switch mode power supply in the desktop computer has failed. Most likely the capacitors in the power has exploded.
You need to open the desktop computer and remove the old power supply and replace it with a new one. Take the old power supply with you to your friendly computer shop and get a replacement power supply with the same wattage or greater wattage.

Need fan for Okia 350 ATX


its the bearings in the fan starting to pack up, best way is to stop the fan spinning when its on with a small pencil and this should re- align the bearings in the fan and stop the noise, you will need a new powersupply the fan is on the way out, just a temp. fix for you to stop the irritating noise

My computer is making a buzzing noise the fan is working and friend told me it was probably the power supply


I would first try cleaning the computer and removing as much dust as possible from your computer. Also clean the fans, this could be the reason why your fan is working so hard. Just make sure your computer isn't turned on and not plugged in.

Ultra 350 Power supply very loud fan


Hi,
It's not normal for the fan to be loud, what makes them loud is either a build up of dust on the fan blades or the bearings are going on the fan itself.
If the PSU is working fine then you can replace the fan itself from an identical PSU. It does mean taking the PSU out of the computer and fitting the fan yourself.
Alternatively you can purchase another PSU.



Regards.

Loud Humming Noise from P/Supply


Yes, it is time to replace it. Open the case and make sure it is a standard size before you buy another one. Just measure length, width & height. You can put a higher wattage supply in there, it just won't have to work as hard to power your computer.

My PSU model ATX-1956d is sick! Any natural remedies out there?


Hey Vrob,

Power supply fans rattle and vibrate when the fan bearing is worn out. They rattle even louder and harder when cool or cold, and quieten a little after warming up and expanding. I would get it out and seek a new one like it. From what you are saying, the computer is not a brand name, so it's probably a clown using standard power supply. take it out to the computer shop; they'll get you a new one. Fans can be changed but fan out is fan old is the rule.

Good luck

Loud fan and wont turn on


power supply is probably shot and you are feeding a voltage way over what is needed. I have a dell that refused to operate one day. I went to www dot affordablesurplus dot com and found a 350 watt power supply with all the RIGHT plugs. Never had a problem since.
