2500k+480 SLI with a 750 watt Silverstone Olympia

post #1 of 10
Thread Starter 
I picked up two 480s for a good price ($140ish each) and they should be here by early next week!

I currently have a 2500k and a Silverstone Olympia 750.

Ive done some research and have read mixed results. Some say 750 is fine some say you need 850+

Would like to hear some opinions before I get them smile.gif

I would say you're definitely going to be cutting it close. You won't have much room to add voltage for OCing at all. I have a 2500k and two 480's all overclocked heavily on a 1000w and ihad my doubts about it.

I wouldn't be overclocking the cards, if that helps.

You may be cutting it real close with the SLI 480s on the 750W. Though without overclocking them, and maybe a slight to no overclock on the CPU you should be under.

i wouldnt do it >.<. the 480s are gonna waste around 500w alone. and then the 120w on the proccessor, thats 620w, not including fans and hard drives, especially since power supplys lose wattage. and the 480s may pull off 300 each, so that would be around 720.... seems risky

You'll be fine, and you could even do a little overclocking, I wouldn't overvolt though. but that thing has 60A on the 12V which is plenty, and it has enough fixed cables. How much has the PSU been used?

With my old 480sli setup an 980x my 1000W would get pretty hot under gaming an benching. so i would say get a 875W min.

Thanks for the positivity! Haha

Ummm...Ive had it since last summer, its ran two 6950s rock solid with a previous build, and is currently powering a lowly 2120+6870.

I'm not going to over volt them, probably won't even overclock them, just the CPU!

Then you should be good to go! Just make sure it's cleaned out. I'm sure it's past its warranty so just crack it open and spray out all of the dust.

Should be fine, it's not like you're heavily clocking everything and overvolting it.
