I plan on running 2 EVGA GeForce GTX 770 ACX in SLI, but i dont know if my current power supply can handle it. It's a Tacens Valeo V 700W Plus silver, the one at the top: http://elchapuzasinformatico.com/wp-content/uploads/201...

Hi - The posted requirements for the gtx 770 are the same as for the gtx 780. However, the
gtx 770 requires less power. With that said, your PSU is probably insufficient for a dual 770 rig.

Taken directly from guru 3d's actual testing of the gtx 770:
"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"

So, I would say the 700w unit you have is risking it. It will prob work some of the time, but expect shutdowns.
If I were you, I'd upgrade the PSU, min 750w, but 850 if you ever plan on OC.

Estimated wattage would be around 650W so like the above suggests it's good to give yourself comfortable headroom.

EVGA 750W 80+ GOLD

It's all about what you're comfortable with, once you've cleared it. Always look at the +12v rails
