OCZ ModXStream 700w PSU xfire?

Thanks Johnny, sounds good. It just sucks that they're so expensive.

I'm not a gamer so I settled for one XFX version of the ATI Radeon HD 4770 video card. Got it for $109.00 and shipping was free.

That's not really expensive. That's about average for a good PSU in that capacity range. And even so, a 650 watt Corsair or Antec has more usable power (50 - 52 amps @ 12 volts compared to the OCZ's 46 amps).

I was talking about the 5870. Plus I would have to get a new mid to high end mobo. Pretty expensive haha

Ive been looking at this power supply as well, and while the wattage is enough i am fairly certain it cannot support Crossfire for two 5850/5870s due to each video card needing two PCIE connectors, so 4 in total with two cards. and this power supply only has two PCIE connectors... not 100% certain, but am I right?

Yeah it doesn't have enough. but molex is fine i think.

im a bit of a noob, not completely clear what you are referring to... are you saying you can convert the 4 molex connectors on the PSU to PCIE?

If yes, does the video card or the PSU come with adapters?

Yes, sometimes the video card will come with connectors but not always. You can get them at newegg.com. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

can anyone comment on the quality of the PSU?

there is a deal to get this for $50

but there was a link to a HardOCP review that gave it some bad reviews?

i am looking to get a PSU

Intel i7 920
2x ATI 5850 crossfire

i can't really comment on this PSU as I actually don't have it and also looking at for my build but HardOCP did re-review the power supply to "rectify" some issues with their original review

worth a look

an i7 plus xfire is pretty power consuming. You might have to bump up to an 800+w. Personally if I had the money with your setup I would go for the 850 corsair.
