Corsair hx650 fan powers on briefly then stops

As the title states.

I bought a powersupply on ebay listed as 'new' but it turns out to be faulty.
Is this an easy fix or should I return it to the seller?

I've already tried jumping it*

  1. If the fan is not needed several of the newer ones dont' spin. Try using the thing and seeing if it will start to spin when its under load. You've already opened it. I suspect its just turning off the fan when its not under load/warm to keep the noise down and total usage on the barrings down.
  2. The PSU fan on Corsair PSUs only turns on when the PSU needs to be cooled, it will spin up right in the beginning until the PSU's fan controller kicks in.
  3. That's the thing.
    It spins and stops but when I power it off and on again, the fan no longer spins at the beginning.

    Do you guys reckon it's the mobo then?
  4. I don't think there is a problem at all. I think you need to run a stress test or something on your computer with the case open and see if it spins up when needed. and if by "power it off and on again" you mean turn the computer on and off again with the power button, or restart then it wouldn't affect the powersupply...


    The mobo has nothing to do with the powersupply it absolutely can not cause this this issue. The power supply decides for itself when to spin the fan.

    I meant do you think it's the mobos fault the pc doesn't boot up*

    I can't run a stress test or anything because the pc won't boot up at all
  6. Oh hell... from the way you wrote you title me, and I assume Pinnacle both assumed you meant you turned on the power supply, the fan on the power supply spun, and then the fan on the power supply stopped. You never mentioned that your entire computer wasn't working in the mean time so we focused on the power supply fan... yes that is a much bigger issue lol.


    Does it ever boot up? or is it a 100% failure? Has this computer ever worked as a whole prior to the power supply? and if so why did you change supplies? If the old supply died, how? (did it just stop working or go with a lightshow?)

    Some PSUs will spin the first time it's plugged in but not after that. If it spins under load you're fine.

    I bought it 'new' for first ever computer build. I haven't ever changed supplies or anything
  9. Okay so it still may or may not be the power supply. Guessing you don't have another power supply handy so try this... unplug all optical drives, unplug the hard drive, take out the GPU (assuming you have one), only use 1 stick of memory and the processor on the board. Double check the 24 pin power connector is plugged in properly and the 4+4pin connector next to the CPU is also properly installed, and then try to power on the computer.

    I don't have any ram atm, I was only hoping for a bios boot

    The 24 and 4 pin are plugged in but still nothing

    *Don't know if it's worth noting but the psu fan doesn't run on start now
  11. Well, it's either a bad power supply or bad motherboard, I'd look at the power supply first.

    How do I check then since the fans keeps turning off

    Worst components to have to check, you need a second board or PSU you can switch out. There is no easy way to test if you don't have a stockpile of components.
  14. UPDATE!!!!

    So I dont know what this means. I got the PSU to supply power-ish to the mobo. The power LED turns on and the cpu fan spins but I can get the bios to appear on screen. Also, the LED turns off and on every 10 seconds or so in which I assume is perma restarting?

    Does the screen turn off when the LEDs do?
  16. Heck I guess I'll ask since we dont' know mind telling us what your current build is? perhaps there is some sort of issue with compatability

    The screen doesn't turn on at all. This might be because I have no RAM? But I did some reading, the mobo should beep if theres an error right? I get no beeps

    This assumes you plugged the speaker into the area where the front panel header is that came in some tiny bag that you hope you haven't thrown away right now :)

    Oh, I thought it's buuilt in to the motherboard :l
  20. lol nope, looks kind of like a tiny microphone usually, two wires coming off plugs in same general area as the power connector for your case.

    Alright.

    Thanks for your help Supahod, P1nnacle. Hopefully it's only the RAM thats the issue now. I need to find some ram before my buyers protection runs out
  22. If you're not on a laptop right now, and its DDR3 ram, steal it out of whatever you're talking to us now one (of course its probably a phone so it wont' matter lol)
