Is 5 case fans too much for a 1050w psu?

post #1 of 10
Thread Starter 
Hey, i got the xfx black pro fully modular 1050w gold psu, but after i upgraded the fans, the pc has died several times due to power surges...

do i have too many powerfull fans in my case?

I have deactivated 4 of the door fans which is 120mm 2000 rpm dans with led connected to a fan control with led.
2 on the roof 1600rpm and 800rom led
one led 230mm in the front
and H60 fan and noctua NH-D14 fan onto the H60 for push and pull

What in this setup can cause the power surges? All fans exept the ones in the door is connected 2 on each on a molex

So what else can cause this?

1050 watts is more then enough power your system you could have much more hooked up to your PSU if you PC shuts down its not because of the PSU unless its broken

Sounds like either your PSU is broken or one of the fan is messing up your PSU

Yeah theres pretty much no reason for your psu to be overloaded. Fans are ussualy the lowest wattage component.

You also dont mention if this happens when your rig is being used under high load. Hlcheck to make sure the 12 volt rail isnt split into 2 rails. If it is, its likely your gpus overloading a rail

Ok, cause the exhaust fans on the top is not much important (want to revert to my old fan) but the front fans is crucial cause of the gpu's.

All your fans together use about 25w max.

It's not the issue.

You've got enough juice to handle as many fans as you want to install.

Check all of your fan connections and make sure they are secure and make sure that none of them are shorting out. Check the connectors and check for bare wires. Make sure that both the male and female connections are making good contact when connected.

I'm betting this is more the result of a bad fan, bad connector or bare wire shorting out somewhere.

The average 2000 rpm fan will use roughly 4 watts.

(watts = amps * volts)

Ok, so it has to be either a loose fan connector of the molex? or the fan control which has 1 dead and 1 loose connector?
