52A should be enough right?

post #1 of 5
Thread Starter 
Building a friends new rig.

He's going to be using

X38 board
2 HD4850's in Crossfire
Q6600
1 WD 640GB HDD
1 Optical Drive
2x2GB of DDR2 ram

I calculated it in my head and i think a Xigmatek 650w should be enough to leave decent headroom for add-ons but i'm wondering if he needs the 750w with 8 more A

What do you mean? The rig i put together came to a total of $1350 based on what he wants. He's trying to keep it under 1400 and after shipping if i add the 750w it will be over. I figure i can remain under the budget if i only need that 650w.

The 4850s have a power envelope similar to the 3870. With a quad and 2 of them I think you would be around 400W (that's with everything OCed to the max, it would be closer to 300W without OCing). So there is plenty of headroom with the 650. I'm assuming you wanted the Xigmatek for the modular cables and if so, it's a good choice for that power range since the Corsair 620, Toughpower 650 and Seasonic M-12 are usually a little more expensive and the DA650 is usually a lot more expensive.

Yea i was figuring 430-450w at the absolute most with everything heavily overclocked which is still under 40A and theres 52A of power.

Yep your exactly right he preferred modular and since the 650tx and the xigmatek 650w are the exact same thing just about i choose the Xigmatek for him.
