Just replaced power supply, no video display and brief power to usb.

[theguy1991]

I just replaced my power supply because I just got a r9 280x. When I hit the power button, the fans run and it sounds normal, but there is no video signal to the monitor. Also I noticed that my mouse light lights up for about 1 seconds and then shuts off. There are no lights on my keyboard either. I did the "hold down power button" trick and that didn't work.

what power supply you got? did you connect all cables to the new psu?

I bought a Corsair CX600M. I have all connected cables plugged in.

Thanks. I've been planning to update it... don't mind the color scheme lol.

@OP Honestly any advice I give you will be covered on the link I was talking about earlier. If you ran through the checklist thoroughly then it's likely there is a problem with your hardware.

Ok I've put back in my old video card and everything worked fine. Mouse stayed on and I got a signal to my monitor. It has to be something with the R9 280X?? The fans run on the 280x so its getting power.Also I'm not getting a signal with HDMI or VGA.

Also my motherboard is an IPISB-CU(Carmel 2). Running 8 GB DDR3 memory. Core i5-2400 3.1 ghz.

Should I update the BIOS? Would that solve the problem? I don't understand why my mouse and keyboard wouldn't work either though with the R9 280x plugged in.

I've gone through the checklist and I've done everything I can think of, its something with the 280x. 600w should be plenty to power that card right? I'm not running a ton of stuff that would require a lot of power on my pc either.

Some prebuilt pc's motherboards have problems when trying to upgrade the graphics card due to BIOS restrictions. Was your old graphics card part of the original pc, or was it one which you bought separately?

The old graphics card (a 7770) was one I bought separately. I recently bought a new case. An NZXT Phantom 410 and moved all parts from my prebuilt HP H8-1114 into it and its been working perfectly. I bought the case because I needed room for the 12 inch 280x. But like I said I plugged back in my 7770 and everything worked perfectly, even with the new PSU. So I've narrowed it down to something wrong with the 280x.

Have you tried clearing the CMOS?

Have you tried clearing the CMOS?

I just did that too and its still doing the same thing.

sounds either the R9 or the psu is not working as it should. can you download HWmonitor and see what it says on Voltage for the 5V and 12V. but it sounds like your Radeon 280 is acting up.

Upgrading the motherboard solved everything. My outdated motherboard was the culprit
