Guys, my friend is having this mobo.
*h10025.www1.hp.com/ewfrf/wc/document?docname=c00783614&lc=en&dlc=en&cc=in&lang=en&product=3349175

He wanted to buy a GFX card and I adviced HD4870. He bought and first it showed "less power" or something like that error (I've not seen, heard from him). So he changed his SMPS to (Corsair 650Watt).
Now his mobo is not getting power.

What might be the issue and solution?

Bond, Desi Bond!
Did he put all the power connectors properly and did he turn on the switch on the back of UPS?

1) power connector for CPU socket
2) 24pin power connector
3) on/off button on the back of PSU
4) lose contact with the power socket.

As he says, he has done all this. And even followed the manual while doing this.

B/W, there is no issue with his mobo right? means its capable of holding HD4870??

but some PSUs get damaged if set to 110 and connected to Indian 230v plugs.
My frend fried his CM EP.

While some goos quality PSUs just dun run if wrongly set. look for a changeable switch at back of PSU.

It seems the motherboard..has onboard graphics.
Has that been disabled from the bios.
Also try to reseat the GPU once again.
Has he put in both 6 pin power connectors which the GPU needs.
His new powersupply is good, it should support it. Also there is no switch on the Corsair 650W for power selection. It auto programs as per the input..110V or 220V.

Also do one more thing....remove the GPU, and reset the CMOS. Pull the battery out..and let the system wait for 2-3 minutes, with all power disconnected, then put in the battery, go into the bios, enable onboard graphics, and boot into the desktop. Then shut down, plug in the GPU, and goto bio (restart)..and disable onboard graphics, and make it PIC-E....
