ASUS RADEON R7 250 power issues?

Cameron Elwell · Feb 20, 2014

I have recently purchased both a Seasonic S12II PSU and a Radeon R7 250 GPU and for some reason the PC won't boot with the graphics card installed? I thought it might have had something to do with the amperage of the PSU but it says it has 10 AMPS more than the minimum but what I think could be wrong is that it has 2 12V+ Rails... Any help would be greatly appreciated as it is for my grandmother's PC that was supposed to be a Christmas present but for the life of me I can't figure out what's wrong.

Thanks in advance.

Pl provide the system specs. Pl confirm if this is the model you are talking about: SeaSonic S12II 520 Bronze 520W?

It has 40Amps on +12V rail which is sufficient for your system and it is one rail.

Pl provide complete description of the problem. Any beeps, any display,

Plug in the on board card run this program and remove all drivers restart go into the bios switch the graphics from iDE to PEG (If you have the option it should be under under integrated peripherals) plug in the new card re install the drivers and it should work

Sorry EasyLover its the S12II 430W psu. Sorry can't go into great detail with the system specs it is my grandmother's PC, but from memory:

Intel i5 2400
8GB RAM
ASRock Motherboard (not too sure of the specs, yet)
The Seasonic PSU
and trying to Asus Radeon R7 250 graphics card

Once plugged into the system the unit powers on, but no display, in both the GPU and onboard graphics. No beeps but once powered, doesnt display anything. Unplugged runs like normal.
Thanks for the help.

pfunkmd will try what you said tomorrow, and post results. Thanks for the help.

GPU is properly fitted, fan is running and in northbridge configuration it has been set to use PCI express as main graphics but still NOTHING.

Running out of ideas ..
Motherboard is an AsRock H61

if you have more than PCIe slots pl try to plugin GPU in any other slot and try to boot the system. Also check the slot with voltmeter.
