Can I SLI?

[Bozzz]

Hi, I am thinking about buying another graphics card for my pc and sli with my current one, but I fear I may need to buy another psu with more wattage to supply enough power. Can you take a look at my build and tell me what you think? Thanks for any and all help.

Yeah, you'll need a different PSU, something like 750-850w would be good.

This would be a fantastic choice:

Here is Guru3D's power supply recommendation:

GeForce GTX 770 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 770 2-way SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.
GeForce GTX 770 3-way SLI - On your average system the cards require you to have a 1000 Watt power supply unit as minimum.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.

Not Overclocking - 750 watter
Overclocking - 850 watter.
