I am having an issue with my power supply. Every time I start up a virtual machine after a while my computer shuts off.

The power supply that I have is a Corsair CX750M.

My Specs:
  • 1 SSD
  • 2 Sata HDD (RAID 1)
  • 1 CPU AMD FX(tm)-6300 six-Core Processor, 3500 Mhz
  • 1 Nvidia Geforce GTX 680
  • 1 Gigabyte Motherboard
  • 2 Acer 19" Monitors

You sure it's the power supply? Theoretically a PSU shouldn't have a clue you're running a VM. I'd suspect a mobo/driver issue.
 
I agree with Darren Highly doubt this is a psu issue. Has to something to do with the vm. Check bios to see if there is any virtualization settings that need to be changed.
 
Well let me rephrase that, it seems like it happens more often when a VM is running. I could just be type on a forum like I am now and it will just shut off.

I think the Power Supply is slowly dieing.
 
Well, all you can try doing is replace it with a different power supply and see what happens. You can also check event viewer for any signs of errors.
 
I highly doubt it's the damn PSU. You have a driver conflict with the VM and your host. It's causing the shut down. I can bet 50 smackers that is the case. That PSU should be of high quality. Never the less, if the PSU is about 7 years old it should be replaced.

What VM software are you using? If it isn't VMware Workstation Player, then it's more than likely the VM software. I found that other VM software just wasn't up to par.
 
Agreed, but all components suffer failures no matter the manufacture.

Failing psu's usually cause intermittent problems, one component will seem to causing an issue and then all of a sudden another. You should first try to check your temperatures, as this is easy to do, have a look at your heatsinks, are they full of dust? You could try removing ram sticks next, just leave one stick in and see if the problem returns, alternate between the sticks.

I'm sorry but you are so atrociously bad at reading threads you should really reconsider responding if you haven't actually read everything.

I believe you owe me 50 smackers.

If the PSU is that old it's worth a replacement. Give the machine a good dusting too while you're in there.
 
A computer just shutting down in my experience has been motherboard failure, graphics card failure, processor reaching it's thermal limits, or bad drivers.

As was stated, probably a bad driver.
Maybe a video card driver.

...and I said if the PSU is over 7 years old it should be replaced.

A PSU won't be a factor with a VM. A VM is not going to magically pull in tons of amps. It's a driver conflict with the guest and host. That's what I'm thinking.

Are you actually incapable of reading? He said it happens outside the VM too.
 
I did replace the PSU.

The problem seems to have gone away but I also don't run it as often anymore (My power bill was a little high last couple of months).

Thanks for the help guys.

High quality? LMAO! No CX are high quality.

My extensive use of them and their overall high reviews on Newegg suggest otherwise. Every single CX model on Newegg is 4 stars. They're not top of the line by any means but they're definitely of good quality.
 
That's a shocker. CWT had a record of cutting corners. Maybe they cleaned up but still I don't trust em.
 
I've put over 10 of them in builds, most about 5 years old and only issue I've had was a noisy fan, and that ended up fixing itself.
 
I agree, I always use the cx430 in my client builds and have had no problem. It's better then any OEM psu they use today. And its not like they need to run SLI/Crossfire or have a single high end GPU.
 
That's what I've had in my build since 2011 and I'd say its somewhat on the high end these days... :rolleyes:
