Will a 850W PSU be enough for...

post #1 of 37
Thread Starter 
Hi everyone,

I am thinking of building a new computer. Here is what I'm thinking of:

CASE : Coolmaster HAF X
MOTHERBOARD : Gigabyte GA-X58A-UD3R
CPU : Intel i7 950
RAM : 6GB 1600Mhz
GRAPHICS CARD : Gigabyte GTX 580
PSU : 850W Antec ATX 80 PLUS
HDD : WD 2TB SATA HDD 64MB
DVD ROM : LG 22X DVD burner
CPU COOLER : Zalman CNPS9300AT

Should I add anything like a SSD or get rid of something? I don't really want to go up much in price.

Will that PSU handle all that? I might be overclocking in the future as well. Should I get a better PSU instead?

Easily,

If you're not going to SLi you can drop that to 650w, I'd go with a 750w to be sure though.

Check my rig, my PSU isn't really getting stressed at all.

550W for a single 580, 850w for SLI

I'd never do 550w for a single 580, i'm dubious about putting much more in my machine and i'm running 650w

So it's the graphics card that uses the most electricity?

And is it worth it to get a SSD?

Understandable, but over at anandtech they show a whole system drawing 450w from the wall. I personally wouldn't be afraid for it and some OC on a good unit.

And SSDs make good boot drives and I enjoy mine. If you want to save some cash it's optional and you can always upgrade down the line, and the small gains are nice.

Nice system, I would prob consider another harddrive, Especially if your gonna use one large drive an partition it...I would recommend two drives. 1 smaller faster drive like the SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM http://www.newegg.com/Product/Produc...82E16822152185

Then have a 2nd larger harddrive like the 2tb for all your "movies" / music / etc... enjoy the system. Its a good one
Also look into getting a better cooler for that CPU! If your going budget get the ARCTIC COOLING Freezer 7 Pro Rev.2
http://www.newegg.com/Product/Produc...82E16835186134

IF you have more money to spend I love the Corsair H70 W/C http://www.newegg.com/Product/Produc...82E16835181013

Lastly make sure that PSU your considering which is nice can support two gtx 580s. You never wanna be limited by something if you choose to upgrade in the future that you can prevent when building the computer for the first time.

Pretty much yeah. Well, it depends on the video card really. The most demanding items in a computer are the CPU and the GPU.

I think it's very much worth it but it also shouldn't be a priority. You'll probably get more out of a more powerful video card than out of a solid state drive. In other words, if you can fit one in your budget without sacrificing something else, then definitely go for it. If getting one means getting a less powerful video card, then you might want to hold off on the SSD and just get it later.

A single GTX580 runs fine on a 550W. Easily.
