I'm looking to do SLI, but I'm afraid I don't have enough watts. I have 2 questions. First being, How do I find out how many watts I have I've looked at my PSU and I don't see any stickers or numbers referring to watts. (12V1 Not sure what it means) Secondly, I currently have a GTX 760, and instead of buying a really high end graphics card I was thinking about getting two of the same, I'm all ready my motherboard supports it and everything. I just need to find out where I can find my watts, and if I need to upgrade my PSU, for SLI.

Thanks!

Maybe it's the fact that I don't know how to read wattage. It says 12V4 if that means anything. It's a black box but all I see is the model number and the 12v4 and 12v1...

EDIT: Alright I found it out finally! I currently have a PSU ANTEC|EA750 750WRT, So I'm assuming that means 750 wattage. Do you recommend getting a better PSU? I don't really know how good the model is.

Only way is to find the sticker on your PSU! and you will need 700watts based on the recommendation.

760's in sli would require at least a 700 watt power supply, but you should probably go for 750 if you are planning to kinda cheap out on the power supply. Typically if the power supply is older and doesnt have the wattage listed, it is 600 or below. Very rarely will an older psu that isn't labelled well have above 600 watts

Try pcpartpicket.com it will note what does your current parts use with regards to wattage and will auto suggest what psu watt you may need

see sample. This is a plain vanilla build. If you chosed a 600w power supply you would only have a 11% room (this system uses would use an avg of 533 depending the task), a 700W or more like rollis59 mention would increase the breathing room (and the chances of tripping a breaker :)

You won't ever tip a breaker with an inadequate psu, it will just fail to output the proper wattage to your system. Your 100% safe bet would be to splurge for a 850 watt psu from either corsair, antec or any of the more popular brands on the pc part sites.

Do you have a model of your PSU? we can look it up online and get you the exact information.

Edit, I just saw your edit. I didn't refresh the page before I posted this. haha

Yes that's a 750W psu, So, i'd say you are good to go with that particular one.
