New graphics card doesn't work, could it be my power supply?

[f1rew0lf1]

Hi there,
So i recently bought a new GPU (see specs below) but it doesnt work.
When i start the pc the fans on the GPU start spinning, but the monitor gives "no signal".
My mouse and keyboard also do not light up when starting the pc, they used to light up
immediately after starting up the pc with my old GPU installed.

SPECS:
Prebuilt gaming pc
- Motherboard: MSI 760GA-P43 (fx)
- BIOS: AMI v1.3 (latest one available from MSI Live Update 6)
- CPU: AMD FX-6100 six core 3.3GHz
- Old GPU: EVGA E-geforce 9600 gt
- New problematic GPU: MSI Geforce GTX 1050 OC X2
- PSU: Cooler Master Inter ATX 12v v2.31 (600w)
- Operating system: Windows 10 64-bit

I already updated my BIOS to the latest version available. I uninstalled the driver of my old GPU.

So I tested out 4 video cards, here is what happens with each of em:
1: EVGA E-geforce 9600 gt, works perfectly
2: MSI AMD Radeon HD 7770, GPU fans start spinning, windows sound is hearable, keyboard and mouse light up, monitor gives no signal.
3: Gigabyte Geforce GTX 1050 Windforce OC 2g, GPU fans start spinning, no windows sound, keyboard and mouse do nothing, monitor gives no signal.
4: MSI Geforce GTX 1050 OC X2, GPU fans start spinning, no windows sound, keyboard and mouse do nothing, monitor gives no signal (same as #3).

I'm thinking there is something wrong with the power suppyly. Checked all the connectors and they are plugged in correctly (the pc is working with the old card).
Is it possible that my power supply has a small defect which makes it so the old card (which requires less power I think) works, but the 3 other, newer cards, don't work because there is not enough power to supply the whole machine.
I'm thinking this may be the problem because of the mouse/keyboard thing, they don't do a thing with the new power-hungry cards...

Thanks in advance!

Well
The 9600GT SHOULD take more power than the GTX 1050, but it does seem that version requires a PCI-E 6pin

600w is Plenty for those GPUs

What monitor connection are you using for the 1050's? HDMI or DVI?

It could be the PSU considering that the videocards with additional power supply don't tax the PCIe slot as much as those that don't.
It's quite possible that your PSU can't deal with the up to 75Watt power draw from the PCIe slot.

i was thinking that too, but that MSI card uses a 6pin.

Only way to find out if its the PSU OP is if you can try a different powersupply
even if a cheap one, as long as it has a proper PCI-E connector that any of those GPUs need.

I used monitors with both HDMI and DVI, all give no signal...

The strange thing is that all 4 cards require a 6pin and only the oldest card works...

What sequence of POST beeps are you getting

[˜lokkandload˜™]

The board only supports PCIe 2.0x16 and the card is rated for PCIe 3.0 x16..I wonder if this is the issue.

3.0 and 2.0 are backwards compatible, so that isnt the problem.

I suppose it could be the PSU..

[˜lokkandload˜™]

600 W PSU should be enough to drive all those cards tho.

Shut down and remove the dedicated GPU. Connect your monitor to the onboard GPU, boot up and uninstall any and all GPU drivers. Shut down and reinstall the card and boot up connected to the card, then DL a new driver specifically for that card from NVidia.
