new power supply

#1Sergei_DukanovPosted 10/12/2013 9:55:40 AM
looking to crossfire and my antec 750w just doesnt have enough juice. What would be a good power supply that can run a 2 way crossfire and possibly 3 way down the road. The specs are in the sig.

What Antec 750w PSU do you have? 750w should be plenty for CFX 7970.

I got the gamers series 750. But I coed my 8350 to 4.6ghz and might take it back to 4.8ghz when I get a better cooler. I also went ahead and got the MSI r9 280x last night. Thinking about doing at least a crossfire with 2 of them and maybe a 3 way crossfire later down the road. Unfortunately the 4 way is not available for my mobo. I know an 850 will be plenty for a crossfire, but im thinking about a 1000w to 1100w for a 3 way.

leaning more towards evga because I keep hearing of their awesome support, but everything I have gotten from nzxt so far has been awesome. Even the source 210 was much better than I expected.

Not sure what power consumption is on 3x7970 (or 7970 + 2x280x) would be, but I'll assume 1200w is sufficient, unless you are doing some serious OC'ing with the GPU's involving increases to stock voltage.

the 7970 is out of the equation. it will be 2 r9 280x or maybe 3 of them. I may oc them, but nothing like the msi afterburner. I also have to factor in my CPU alone taking almost 200 watts for being OC.

You should still be fine with 1200w.

Edit: And your 750w should still be sufficient for 2x280x.

I'm inclined to say that PCPartPicker is inflating the estimate a bit. But, it's your build. Between the 3 you listed, I'd say either the NZXT or the EVGA would be fine.

Edit: Also, if you're talking about the HCG-750, according to Hardware Secrets, they were able to pull almost 1000w from it.

thats the one I have. is there a way for me to test the wattage on it? Without buying a second card and possibly frying everything if something goes wrong?
