Hi everyone

I would like to upgrade to GTX980 SLI (possibly with 2 ASUS Strix-GTX980, each with a power consumption of up to 300W according to ASUS's official website). I'm just wondering if my PSU wil be able to sustain it. My set up as follows:

PSU: Cooler Master Silent Pro Gold 850W
CPU: i7-4770K, at stock speed
MB: ASUS Maximus VI Formula ROG
Display: Inno3D iChill GTX780
RAM: Corsair Dominator 16GB
SSD: Samsung 840 Pro
HDD: Seagate ST2000D 2TB

Many thanks in advance for any advice.

Wattage wise, yes. Quality wise it'd be a bit too high, the PSU is average quality, known to fail on high loads, I'd upgrade for the sake of safety of the equipments.

If you are going to overclock the gpu, I suggest a 850w power supply so you will have more room.

This is a nice power supply for 115 dollars after rebate.

It is in top 1 tier in psu,
and

IT IS MADE FROM SUPER FLOWER.

(However, if you are not going to overclock, then I guess 750 w will be fine.)
This is a 750 w psu for 80 dollars after rebate.

Thanks everyone for the advice. So it appears that my existing PSU should be sufficient to handle GTX980 2-way SLi.
