[SOLVED] GTX 560 not recognized by motherboard

[UriDubz]

Hi! Good evening, I have a Dell Optiplex 380 with BIOS A07. 4 days ago I bought an used ASUS GTX 560 from Amazon.
Since I plugged in the graphics card my PC couldn't even recognize it. Sometimes my integrated graphics works (meaning the graphics card isn't recognized) and sometimes not (it is somehow recognized but no signal) I'd appreciate if someone could help me, I'm going crazy ;s.

Dell Optiplex 380
Intel core 2 duo E7500
RAM: 8 GB
Graphics card: GTX 560
PSU: 500W

The GTX 560 usually needs additional power direct from the PSU via 2 x 6-pin cables.
Check the card to see if it has any 6-pin connectors on it. If it has, then you must supply power to them if you haven't done so already.

Thanks for replying, I have a 2 molex to 6 pin connector, which is connected only to 1 6 pin. I thought that it would have the 150 watts the fabricant says it needs (75W from PCI-EXPRESS, 75 W 6 pin= 150W).
just investigated and the problem here is that I only have 1 sata cable left, so I have 2 options;
1- Buy a Sata to 6 pin adapter to get additional energy to the GPU.
2- Use 2 separates molex to 6 pin cables.

Which option could be safer?

Oh yeah and a 4 pin cable for the fan... I dont know if a 4 pin to 6 pin exists

If you need to use adapters on your power supply you need a new power supply. Also for that old of a system make sure you have the latest BIOS on it.

None of them, you need a new power supply.
