CrossFire r9 280 Power Question
Hello,
I recently purchased a second MSI r9 280 and was wondering if my Tt 750w toughpower gold will be able to power both cards. I have an i7 4790k (auto OC 4.4ghz), msi gaming 7, 16gb ddr3 1600 ram, a dvd drive, an ssd, an HD, a cpu cooler with 1 fan, and 4 other fans. I do not run my LED lights. And I can always disconnect the dvd drive (after making a bootable usb or something in case windows error). I use a mouse and keyboard and a wired 360 controller at times. There are plenty of empty plugs on my power supply.
The min req for crossfire looks like 750, but I'm wondering if I'll run into errors overclocking? Am I forced to buy a new psu? I've looked at other threads and some say it's ok , others say 850 or higher. but I have a feeling some folks just say 850 just to say 850.
Is there a way to test my systems power consumption?
