TX750M and GTX 780 SLI

post #1 of 8
Thread Starter 
Hello!

I have a Corsair TX750M PSU

At the moment, I have 6 USB peripherals connected to the computer, a single reference GTX 780 (stock clocks), an i7-3770K ( stock clocks atm and voltage with turbo boost and voltage set to auto), an H100i with the 2 stock fans, 2x4GB 1600Mhz Corsair Vengeance Low Profile white RAM, one 120GB SSD, one 250GB SSD, one 1TB HDD, and CM Storm Stryker front panel connectors all connected, a Gigabyte Z77X-D3H motherboard, and like 4 LED case fans.

If I add a second GTX 780, will I ever face ANY power throttling?

I plan on playing on either 3 1080p monitors or one 1440p monitor

Ok. I've seen varying opinions about needing 800w minimum

750w would be fine if you are doing light overclocking. Hell, I think you can run 650w on 780 sli. Someone correct me if I am wrong.
I would start looking into a beefier psu if you want to push the voltages and go for some big overclocks though.

I'll be adding a 780 to my rig in the future for a similar purpose OP. I have a TX750. It did sweat a little when I ran SLI 470's but those things loved power.

You'd be totally fine. It's really rare I see power draw on my rig hit the 750W+ mark, and that's just from the wall and I also have a sizeable overclock on my 2600k.
