PSU - i5 2500/cf 6950 all OC

post #1 of 8
Thread Starter 
So basically new build planned.
Will either be BD or SB, along with CF 6950s or similar, RAM, hdd, WC loop and fans.
What is the lowest wattage i can get away with? Even if its under 90% + load the whole time? Needs to be 100% modular and good quality.
Im assuming ill need around 650w.
Recommendations please?

Decent 650w should be fine, 750w if you want a little room to move.

Personally I would recommend either of these;

Seasonic X650 - http://www.newegg.com/Product/Produc...-088-_-Product

Seasonic X750 - http://www.newegg.com/Product/Produc...51087&Tpk=X750

They are probably the 2 best PSU's on the market at their respective outputs.

I am pretty sure they are 100% modular (I know the X650 is and going by that logic the X750 would be as well)

I know they are pricey, but they are amazing units

EDIT: Yep, the X750 is indeed 100% modular;

They were my first 2 choices anyway and was hoping for alternatives due to being like £120+ GBP.

In that case, what is your budget?

Will make it easier to find a PSU to suit.

EDIT: Maybe have a look at this unit from Silverstone;

http://www.newegg.com/Product/Produc...82E16817256059

It's $30 cheaper than the Seasonic X750, hopefully thats closer to your budget

No budget as such but would rather spend less.
I can get an Ultra X4 1000w very cheap atm. I know its way overkill but its much cheaper than anything new. Is it any good?

Don't get such a large power supply. While it might be cheaper, they may not be as effective as some more expensive, lower wattage. That way they'll pull more power from the wall just to deliver the same amount to your computer. IMO go with a decent 750w or 850w and you'll be good to go. If budget is no problem, go seasonic. Very quality units and modular. This is something you shouldn't skimp on.

Also wrong forum, this is for monitors just a heads up.

My sig rig pulls ~415 watts from the wall while running witcher 2.

The gpu's are wide open, but the cpu, of course is not.

Just get a 750W.

That system will put a lot of strain on a 650W, which isn't too nice.
