Is my psu functioning properly?

[Auklin]

long story short. I have a corsair HX650 gold running an msi gaming mobo, gtx 780 and haswell 4670k cpu. 

nothing is overclocked right now, because I'm not running anything that requires me to yet.

 

when I turn on my pc, the psu fan spins for a moment, then stops.

 

I was told that the psu won't utilize the fan until the power load requires it.

 

quite simply, is their a test that you would recommend me perform to see if my psu is functioning properly.

 

Thanks everyone,

To put load on your PSU, just go ahead and launch a demanding game such as BF3. If your PSU is malfunctioning, your system would shut down due to not getting enough power, or you'll see that your PSU fan isn't on. According to this page:http://www.corsair.com/en/power-supply-units/hx-series-power-supply-units/hx-series-hx650-power-supply-650-watt-80-plus-gold-certified-modular-psu.html, your PSU fan won't turn on until 40% load, or 260W in your PSU, is drawn by the system.

Does your system boot up and work?

That actually sounds normal because I think mine does that too, I have a GS700. I think it's just because the initial startup requires a load therefore the PSU fan spins up. But yeah do what Target39 said and see what happens.

I thought quite a few PSU's now switch their fans off unless required. ?

I'm pretty sure it's because it doesn't need the cooling until it goes under load/reaches uncomfortable temperatures. It's fine.

I have an AX760 and have never seen the fan turn on. Even whilst all key components are under full load! 

 

So, fine I guess.

if I am understanding you correctly I have two tips

 

1. stick a paperclip in the black and green ports on the twenty pin on the psu and then power it on by it self ( not plugged into anything but the wall) this is to test if its COMPLETELY dead

 

2. (and this is what I did last week  :mellow:  ) but the twenty pin and the 12v were not both correctly plugged in ... so uh yeah

yes well the pc need full power when its starts. run prime95 and furmark and see if the fan spins. thats like 350W without OC.with oc ~400W. so it should spin
