Corsair AX760 is a lot more expensive than CS750M. The 750M works in my case YMMV. The 750M is what a consider a bare minimum upgrade. If you are trying to use 2 X GTX 970 or 980 then the supply should be 1100W or more.
Is it necessary to upgrade the motherboard? I'm planning to get the same power supply however get a gtx950 instead. Will it still work?
I didn't change my mother board, and I don't think anybody else in this thread did either. That's part of the reason that were all asking which Motherboard Bios version worked successfully.
Philosophically: If you are changing out the mother board, PSU and GPU Video... you'll probably need a new processor (reusing existing can be tricky) and the memory may no longer be compatible. At that point, you might as well get a new case or just build a whole new PC from scratch.
Just my $0.02,
I'm planning too use the same 750W PSU as it fits into the dell xps8500. Instead of a 970 i'm planning to use a MSI GTX 960. Assuming I set it all up correctly, I wont run into any problems? Shall I follow your way and make changes to the motherboard?
It was my first time doing this but I had some purchasing guidance from one of the pros at microcenter and install seemed very straight forward based on what I read. Everything went in fine and fit properly. I followed the directions to uninstall the existing GPU driver before replacing and download the latest driver for the new card but not install it.
When I press the power button the boot screen loads (shows the Dell logo and blue progress bar, so I know the display works). Once the progress bar is full nothing happens and after about 30 seconds I get a beep from inside the case. Pressing F2 or F12 in the boot screen does nothing and makes ticking sounds if you press it after the beep starts. I did what trouble shooting I could but I am stumped. To me it seems like the OS isn't loading.
I checked all of the power connections, they are all correct and tight. All of the SATA cables and such are tight. I put my ear to the HD on power up and I can hear it wind up. The HD makes a slightly different sound when it starts spinning, I don't know if that means anything... Whats going on here??? I dont know what BIOS I have. Should I reinstall the old card and check the bios version?
BIOS is up to A12 on the 8500
* Download/Save the file to the windows desktop
* Before running A12, I would install the Prior Bios in order
* Disconnect any external hard drives, keys, printer, scanner, etc. You only want the USB mouse, USB keyboard, LAN, monitor connected
* Run the executable from Windows
* Allow the system to complete the installation and restart automatically. Do not force a restart or power off

Yes. Absoutly check the bios. You might have to switch back to the old video card to do it.
That's typically the first things folks do pre-upgrade. After that... (if that doesn't work)
I can only make educated guesses from years building PC's.
The beep and startup mean it probably isn't a powersupply issue.
The fact that you see a screen means it probably isn't an explicit motherboard hardware issue.
I'm guessing that it's a driver issue, and/or your video is switching to one of the other ports (HDMI, VGA, Display Port 1 or Display Port 2) -- a different one that you see during boot. There is also a possibility that the card is defaulting to a resolution that your monitor doesn't support (too high, to low, or just not accepted) and/or a format that is not accepted (such as HDMI that uses rgb vs ycbr and all the 4/4/4, 4/4/2 and 4/2/2 settins in 8-bit and 12bit).
I'd play with additional monitors and additional ports. Perhaps go back to the old video card and reset yourself to some generic 1280x720 and then switch hardware back to the new card. Perhaps remove all drivesr when you go back to the old card so that you boot the new card on generic video drives... and do the install of the video drivers when the new card is in on "generic Windows Drivers" at ugly 800x600 resolution.
Thats typically where I go from where you are.
And... once or twice (and this is an absolute longshot), I've bent a pin on a DVI or VGA cable while replacing a video card.... and fought this for hours before I realized a pin was broken or missing. I suspect you are using non-pinned cable like DisplayPort or HDMI... but trying different cables is a "Hail Mary" after you've done everything twice with two different monitors and every port out of the card.
Sometimes I never figure out what the actual issue was (I chance so much). It could be anything from one of the times I reseated the card, to who knows what.
There might even be a remote possibility that the card is under powered and you only see the consequence when it attempts to switch to a different resolution. That's more of a "conspiracy theory" level guess... if everything else fails.
