Power supply sizes?

[MintPaw]

So I've just picked up a Radeon HD 6850, and I hadn't checked the watts of my power supply, I look (before I put the card in thankfully) and saw that it was a terrible 300W, after researching a bit I see that this simply won't cut it, so I'm looking to get a new one.

I was look at this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817339009 (585W Two independent +12v rails)
But it doesn't give any kind of dimensions. My case form factor is "Micro Tower", would the power supply above fit? Do would anyone fit? Any comment on the quality of the power supply?

Not a good choice on PSU this 380watt Antec http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033 or this Corsair http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 are better and will run your card. If you can fit the card in the tower then the PSU will fit.

380W lolwut? I'm by no means an expert, but that seems awful, the card looks like it needs to have a min of 500W from what I can see. What am I missing?

Both those PSU's are quality which can not be said about the one you linked to. Here is another bigger option but more money http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
Here is a link to a build where Toms used the 380watt with HD6850 http://www.tomshardware.com/reviews/diy-gaming-pc,2970.html

Hmm, I must be misunderstanding how power supply works, can I run that card in this system: http://www.newegg.com/Product/Product.aspx?Item=N82E16883113175

 

[rolli59]

I can see in the pictures in the link that there is a sticker on the PSU and that it is a FSP unit. What I can not see is how many amps or watts it has available on the +12 volt rail.

Oh, well then can you pretty much confirm that I can run a Radeon 6850 and a 6-core 2.9ghz on this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&AID=10440897&PID=3332167&SID=u00000626

Because that would be awesome.

If you want to know how to objectively determine the power in watts and 12v rail amps. that are required for your Vid card and PC system, then the link below will show you. Then you can shop for a reliable PSU based on objective test reviews of a variety of PSUs. BTW, a $25 PSU IMO is a paperweight not a reliable PSU.

Ok, so I've pretty much resolved to go with one of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182199
or
http://www.newegg.com/Product/Product.aspx?Item=N82E16817170027

What do ya guys think? After I get a suggestion I'll measure for it and buy.

 

[rolli59]

I would get neither of those, but out of two evils the Rosewill is better and notice the short 2 year warranty!
