Bad PSU?

post #1 of 8
Thread Starter 
Whenever I started my file "server" today it was making weird electrical noises from the psu.

I've had this system for a couple months now and haven't noticed this. It only happens at start up. I'm afraid it's going to kill my hard drives devil.gif

System: AMD A-10 5800k
8 3TB Seagate 7200 RPM hard drives
Rosewill Fortress 450W platinum power supply

Could be coming from the fan but I wouldn't have risked in this situation since it can also be some bad wiring. Don't know how good that particular model of Rosewill is but if its faulty then it could damage pretty much everything on your pc.

Its very good and well build

In fact its almost overbuilt

It could be a one off bad unit or as you said the fan

Could it just be from my hard drives spinning up and causing too much of a load on the psu?

I can't imagine it being anything but arcing or fan noise, and I seriously doubt it's arcing, unless the AC power cord isn't plugged in firmly.

Stick some plastic straws through the fan blades and then turn it on. It won't hurt to do this for just a minute or two. No noise = fan problem. Be sure to use only plastic straws or soft plastic tubing because you want something that does not conduct electricity (there can be over 300 volts on some metal parts in the PSU, including heatsinks) and that can't break off inside the PSU.

Are the fan blades hitting any wiring? The buzzing sound can be from that, but generally any sharper sound is from inside the fan, and a few days ago I had an Antec fan that would sound wierd in a certain orientation until I took it apart to clean and relube it.

What else is hooked up on that psu? I mean list everything including any fans, led and other devices.
Shilka said it is very well built so if you're not using 2 video cards or 1 really power hungry card, then I doubt that pc would be able to put much load on a very well built 450w psu.
Well list the other parts for now but I think it is the fan if not a bad unit. Its only been months so RMA it.

Don't think that psu will have any problem powering that. It's either the fan or a bad build if you're sure that the sound is coming from the psu and not the HDD itself.
As I said earlier, RMA as soon as possible.
