PSU Noob - Build Help

ok here are a few choices that will get u ur bang for ur buck and get u peace of mind,

NZXT HALE90-750-M 140$ smackers,

COOLER MASTER Silent Pro Gold Series RS800-80GAD3-US 160$

SILVERSTONE ST75F-P 750W ATX 130$

XFX Black Edition P1-750B-CAG9 130$

Seasonic SS-850HT 850W ATX 130$

thats a good start  

i second that if on a budget, dadiggles choices are quite good, it all depends if ur willing to spend a little more, for a gold or silver rated ps

I like the Corsairs.

You can go for a 650tx if you plan to stick with the one 5850.

If you're looking into adding 5850s in the future, I'd go with the 950tx (I have this - see signature). Yeah. I'd just skip right over the ones in between. Once you add another 5850, you'll want to add another. That's my reasoning for the skip-over.

The 950tx ($150-$10rebate=$140 on newegg these days) has 3 pairs of 6-pin PCIe connectors. Each pair can power one 5850, 5870, 580, etc... The lesser wattage supplies have two pairs of these connectors. I am really liking the 3 5850s. If you ever want to add on, plan for it.

The PSU is the easiest component to take for granted, yet the most important in my opinion. It's a great feeling when you know you don't have to worry about the power and that you have sufficient wattage for just about anything.

i second ubercakes suggestion  

A good quality 650W unit will run 2x5850 no problem.
A 750W gives you piece of mind.
Two great deals on modular Antec TP's.

Personally i'd buy the 750 it's a powerhouse that cranks out over 900W and comes with 3D MARK Advanced.
Nice!
