Help Wanted With Psu


Recommended Posts

I'm in a little bit of a problem here guys.

Does anyone have any recommandation about how big ? what manufacter ?

 

Would appriciate any help aviable on this subject.

 

I thought of either the Antec TruePower 850 or the Zalman ZM850-HP would appriciate if anyone that got either would let me know of his personal expirience with them.

 

Thanks in advance. :)

^^ Thats a good choice.

 

But atm, the 750TX is one of the best bang for you buck power supplies out there..

 

either way, there are many many many choices and I really cannot reccomend one so many, But I would stay within the brands of:

PC Power and Cooling

Corsair

Seasonic

Silverstone

the PC power and cooling 610W only has two PCI-E connectors, in order to run two 4870's you need 4 PCI-E connectors.

Here are some good ones to choose from:

 

SeaSonic M12 700W - http://www.newegg.com/Product/Product.aspx...N82E16817151031

Corsair TX750W - http://www.newegg.com/Product/Product.aspx...N82E16817139006

PC: Power and Cooling 750W Crossfire Edition - http://www.newegg.com/Product/Product.aspx...N82E16817341011

Silverstone ST85F 850W - http://www.newegg.com/Product/Product.aspx...N82E16817256011

750W may work for you but anything below that size and you're doing nothing but wasting your money. ATI doesn't even list an approved PSU below 800W for dual 4870 cards. Makes no sense for most users to purchase a 1000W or higher power supply but makes even less sense to try to get by at a minimum.

Benchmarks show that a 4870 in crossfire is about 420W total.

Then maybe ATI should revise their specifications. On second thought they probably wouldn't as they use the proper equipment capable of showing instantaneous maximum loading. Unlike review sites using $12.00 watt meters.
