Do you think 750W would be enough? and do u need a dual rail psu?

I thought the same thing but it runs fine with just 1 monitor. soon as i put the 3 on it cuts out, but not all games has this effect. Ive just been playing dishonored and it didnt crash. But with crysis 3 and mechwarrior online it does. Same with kombuster. Thats why i mentioned BIOS update?

ive just gone SLI with my 660 ti and i have a 3 way monitor surround setup. But my computer just shut off as if someone has pulled the power plug out. But if i go SLI with just one monitor it doesnt. Is this a PSU problem or maybe a bois upgrade issue?

i have a MSI 660 TI PE. and i want to go SLI. Ive came across a cheap ASUS 660 ti (only 915mhz compared to my 1019)

Now i know its not a good idea to mix cards. but would it really cause my issues?
