Hello aubrey08;

What's the hurry? What PSU are you using now?
HD 7970 only needs a 650W PSU to be happy.

What case does the new 1000W PSU need to fit in?

Using 750w. nzxt phantom case comes tomarrow im gonna switch cases and current case only has 1 fan. By tomarrow i would be adding 100w of fans to power and i clueless what will happen once i even add the 7970 soon i have 2 hours to put in order so i have it when the case comes.

Five 20W per Channel fan control totaling 100W
It doesn't work that way.
Add the wattage of the fans. That fan controller could handle 100W's worth of fans. But that would be like 30+ 200MM led fans if they were the CM Megaflows.
Power supply Master

750W will be fine.

The controller will handle 100W (capability) - 20W on each of five channels. But it will only draw a small amount of power on it's own to light up the display.
The rest of the load is determined by the fan wattages involved.

Sorry i'm an idiot that why im here very new to pc and cautious. I will be switching cases tomm and im pretty scared cause i will be doing it on my own and never done it before. I have a 120cc liquid cooled cpu cooler attached to my board and wires bundled up and my psu sits uptop and this case has on bottom. Looking forward to the learning process. Thanks for your time

Your welcome.

Take your time and look over the layout till you have a clear understanding how everything needs to get routed.

What PSU are you working with? You might need to flip it 180 in that case.

I bought this pc from ibuypower last year, the cooler has no name on it. The PSU is standard xion 700w psu i found it on my paper order which it actually says 700w *** i always thought it was a 750

I like those newer psu that have the individual cords and slots, which make it easier for newcomers and alot more cord friendly/neat looking...mine is bunched and twistide together.....

I couldnt make a match on that number.

A XION 700W label as example:


It's got 46Amps of +12 power which puts it close to an premium 600W PSU.


Yea i have 2 six pin connectors on my 6870. And theres a 2 pin hanging not plugged into anything....plug that with it and i would hit the 8pin required mark correct? Sorry for any confusion
Power supply Master

Right - I was going off a spec sheet that said it only had 2x 6pin... when yours has 1x 6pin and 1x 6+2pin.
Your 7970 will be happy with that.

Best solution

I think you're good to go with what you have.
It would have been nice to find an indedpedent review for that PSU but google didnt turn up any.

The only reason to swap PSUs would be to get something to help with cable management.
But I think you'll find having the PSU on the bottom makes it easier to stuff the unused cables out of the way.
Power supply Master

I think you'll be able to do that. Just detach the cooler fan last and be sure to support it to keep the cable flex at a minimum. A 2nd pair of hands there would be a big help.
