and 500watt PSU

Would the GPU be compatible, the specs say that the PCI Bus is a PCI x 16. Does that mean its a PCI-E?

450 is the minimum requirement for the 660, so you would be better off with a 500W one

Links aren't working btw.

ugg, I copied off another post that I accidentally made that was a tutorial instead of a forum discussion XD. It's fixed now

Yeah the power supply link still doesn't work , it says access denied. Just give me the module or manufacturer

its the CX 500. Also, someone pmed me telling me that HP pcs usually locked their BIOS so that non pre approved GPUs cannot be used. Is this true?

I've seen your exact same PC with GPU upgrades, with the 660 too and it was working fine.
You should be fine with the CX500 as long as you don't over clock

Yeah gtx 660 with cx 500 works fine.

If you were worried about the locked bios situation, don't be. I just recently upgraded my hp pc and put a GTX 600 in it with the Cooler Master V550 power supply. It works well, the only issues I ran into were: 1. It was an incredibly tight fit getting that card in my case and 2. when I plugged the card into my motherboard and powered it on, the motherboard gave me the "error" beeping noise. It, of course rejected the card. There's a simple fix for this that involves disabling secure boot.

Here's the link to my source in case you want to see the full article, or read the short version below.
http://

1. Take the card out and open up the BIOS (button mash the f10 key when the pc starts)
2. From there, navigate to the Computer Setup option
3. Navigate to the security menu and go down and select Secure Boot Configuration
4. If a warning menu appears, just press f10
5. In the Secure Boot Config menu, navigate down to the line that says legacy support and change that to Enable (using the right/left arrow keys)
6. Then go down to the Secure Boot option and change that to disable.
7. Press f10 to accept changes
8. Navigate to file on the top and go to Save Changes and Exit.

Happy Upgrading!
