Probably Buying a Radeon 7870. Questions.

Hi.

For a system using a single AMD Reference Design Radeon HD 7870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 27 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

It would be nice to know what mobo you have before we can say anything about it . . .

you mean 2. only the 7850 uses one in the pitcairn series

I've looked everywhere to find my MOBO, but can't find. I tried opening up my pc, but I have no idea how to locate the name or id of it :3

Found my Mobo modal, it is a H77 Chipset.

Is your computer an OEM computer or a home/custom-built computer?

EDIT: H77 simply tells the chipset, not the motherboard model.

It's an OEM.

EDIT: My computer model is Asus CM6870

What is the model of your computer? A web search for its specifications should give the motherboard model and/or specifications.

if its h77, it most likely has a pci-e 3.0 slot and is comparable with all gpus. the only thing stopping it is really PSU and Case(gpu length room requirement)

The computer modal is Asus CM6870. Won't any video card fit aslong as it's pcie?

yes pci-e cards are universally fit. but its not motherboard to video card compatability one should look at. its case to video card, as pci-e isnt going away for a long time.

a very crude analogy is like an engine is compatable with all the right mechanical parts, which are universal to some extent. the problem isnt the engine to like wheel compatability, its the engine to frame compatability, and the frame is the computer case.

It can fit I believe. If not, worst case scenario.. I'll buy a new case.

is this http://www.newegg.com/Product/Product.aspx?Item=N82E168... the best cost efficient psu I could buy?

PSU's with promos would be most cost efficient
