HP7-1110 Help!

[sojubrewmaster]

Hopefully somebody can help with a issue I've been having. I have just purchased a HP 7-1110 desktop computer along with a Cooler Master eXtreme Power Plus Series 500w ATX12V 2.3 Power supply as well as a Galaxy GTX 560 2 GB graphics card in hopes of running Starcraft 2. I got all the cables connected but I was unable to get the graphics card to work. I would use the vga cable and it would give me a no signal on my monitor.

I tried connecting the VGA cable to the pc and it works so i figured the error was in the graphics card. However after shutting down the computer and trying to turn it back it doesn't even power on anymore! Can anybody help!

Hi,

It appears that something maybe has died.

The Cooler Master only has one 6 pin PCI-E power connector and the video card needs two. You need to use the molex Y adapter for the other PCI-E video card connection.  You might run into a 12+ volt balancing issue depending on which internal +12 rail the molex connectors are tied to. Try a different set of molex connectors from a different power cable if available.

If the above doesn't work then try the below suggestion.

Remove the new video card and connect the monitor to the motherboard port. See if the PC powers on.  If the PC powers on and works then the graphics card is the problem.  If the PC still doesn't power on then try the old PSU without the new video card.

I prefer a single rail PSU like the Corsair CX600.

Got to agree with the guru on Video Cards!!!

That card's TDP max is 150W. The PSU you selected is a dual rail, only supplying 12V @ 18A per rail. The challenge is the max wattage is 180W per rail.

Again, you need to have purchased that 2nd PCIE 6pin adapter, and balance the load.

So in the scenario that the PSU is causing problems would the  P7-1110, Corsair CX600PSU, and gtx 560 2gb able to work together? Would the Corsair CX600 have the 2x PCIE 6 pin adapters available?

Yes, the P7-1110, Corsair CX600PSU, and gtx 560 2gb should work together. Here are the specs for the Corsair Builder Series CX600 V2 80plus power supply. According to the specs, the CX600 has 2 PCIe connectors.

Please follow through with Big_Dave's suggested troubleshooting before moving forward with getting a new PSU.

So it appears that I had a faulty power supply as the stock PSU was able to power the computer. I am going to pick up the corsair 600 power supply. I was wondering how do you turn off the integrated graphics on the P7-1110 so that the graphics card can be used?

Hi,

When the graphics card is recognized by the bios, the on board video processor will automatically get disabled.

Some of the AMD based PCs can with the right processor, motherboard and video card run dual graphics mode without having the on board video processor disabled.

BTW-----It's possible that you could have a double problem. The wrong PSU and also bad video card.  I have seen cases where an undersized PSU caused the video card to fail.  I am hoping that you are not in this situation.
