Power supply for GTX980 SLI

Ruttiger · Oct 8, 2014

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.

michaelhall :

Agreed; a 750W power supply should be enough to run those parts.

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.

Can't really be sure, the PSU quality is averagish.
