Is a 600watt power supply good enough for sli 1080s and an i7 4790k? no overclock

currently I have a 600 Watts - Standard 80 Plus Certified Power Supply - SLI/CrossFireX Ready [+6]. I'm not sure if it's safe as of right now to put in my other 1080 because I do not want to fry anything. Any thoughts are really appreciated!

    Sounds like you are a victim of ibuypower or cyberpower. What you posted is not the make and model of a PSU it's marketing jargon that usually means "this is one of the cheapest 600w PSUs we could find and overcharge you for". Quality wise you'd be lucky if the unit is mediocre quality.

    To get the actual make and model of the PSU you need to open the case and look at the PSU.

    That said even a good quality 600w unit would not be recommended to power 2 1080s. Depending on the rest of the system specs you are likely going to want a 750w or larger PSU.

  2. I agree with nastyid, SLI'd 1080s on a 600W PSU is cutting it close even on a high quality unit, wouldn't recommend trying it on the likely PoS-quality PSU installed in many prebuilt PCs.

  3. The combined +12V rail capacity of a 600W PSU would be too weak to handle two GeForce GTX 1080 graphics cards in 2-way SLI mode.

    Depends on the PSU, though I wouldn't expect whatever Shenzhen special PSU may end up in pre-built systems to use DC-DC converters for secondary rails. Some PSU vendors do have such models all the way down to 300W.

  5. Isn't the CPU an Intel Core i7-4790K?

    I wouldn't even recommend trying it with a Seasonic PRIME 600 W Titanium PSU.

    SLI 1080 means 2 1080s and 550w is not enough for 2.

    You're ignoring the two GeForce GTX 1080 graphics cards in 2-way SLI mode that the OP is asking about.

  11. There are many good ones available, but which is best for you depends on your location(country) and how much you want to spend.
