Sorry, had a small case of dyslexia I guess....the old PSU was a X-Power 585.
Installed new PSU, now Desktop lights and fans turn on and off
Hi,
So far having a crappy weekend, my computer turned off yesterday after I started smelling a slight burning smell which seemed to be coming from the PSU (an X-Power 858 PSU). So being the weekend and probably not being able to get any technical support help from any big companies, I figured I would buy a new PSU and see if that would work. I purchased a Corsair TX850W PSU as a replacement, connected it up and powered it on and all I got was the fans and lights turn on for 3 seconds and then turn off. This is what is continually happening if I try to turn the computer on. Out of curiosity I even went back and reconnected the old PSU back on and it does the same thing the new one does. I need some help on what could be the issue that I'm not finding, and I really hope it is not anything more serious. Thanks. :upset: :4-dontkno

Welcome to TSF!
Can I ask of you to tell us your computer stats.Is it prebuilt or custom?How old is it?

It's a good possibility the old low quality PSU did some damage to other hardware when it failed.
A bench test is the best option to determine what was effected.
Remove EVERYTHING from the case
Set the motherboard on a non conductive surface. The motherboard box is perfect for this. DO NOT PLACE THE MOTHERBOARD ON THE STATIC BAG! It can actually conduct electricity! We are going to try and assemble a running system outside of the case.
Install the CPU and heat sink.
Install 1 stick of RAM.
Install the video card and attach the power supply connection(s) to the card if your card needs it.
Connect the monitor to the video card.
Connect the power supply to the motherboard with both the 24pin main ATX Power connection and the separate 4 or 8 pin power connection.
Connect power to the power supply.
Do NOT connect ANYTHING else. Make sure you have the power connector on the CPU fan connected.
Use a small screwdriver to momentarily short the power switch connector on the motherboard. Consult your motherboard manual to find which two pins connect to your case's power switch. Then touch both pins with a screwdriver to complete the circuit and boot the system.
If all is well, it should power up and you should get a display. Then assemble the parts into the case and try again. If the system now fails to boot, you have a short in the case and need to recheck your motherboard standoffs.
If the system does not boot after this process, then you most likely have a faulty component. You'll need to swap parts, start with the power supply, until you determine what is defective.

Thanks. My computer is not prebuilt (Dell, HP, etc.), it is custom (but not actually built by me, AVA). and it is about a little over a year old.

I would suggest not going back to the shop that sold you that Orion PSU.
