I'm pretty sure I don't have a good enough psu to supply 2 ATi Radeon gc's.

I'm most likely to open my case tomorrow to figure out my mobo and psu, but anyway I was wondering what kind of recommended psu would be good for gaming.

Does it matter what kind of motherboard I have in order to select the most appropriate psu ?

Is this system a prebuilt or did you build it?

As for a PSU, I have heard only good things about the Corsair brand.

You need to know if you have a crossfire motherboard first. Download in install PC Wizard and it will give you your info. on your whole setup.

Okie Dokie.

Havn't built a pc myself yet. Seen fragments myself, and i've only upgraded a Graphic Card and Added more RAM into my old computer. This is still freash out the box, waiting for UPGRADE STAGE 1 which im hoping to accomplish before Febuary.

EDIT

I'm guessing that mainboard is the same as motherboard.

Gateway TBGMO1

& my Bios is AMI

BTW thanks for the download

kk hold on i'm going to rephrase that, because I was researching the mobo and I figured out some of the missing pieces

Mainboard ~~~~~ I don't know this part ~~~~~ Chipset

TBGM-01 ~~~~~~~~~~ **** ? ~~~~~~~ X58


This is what I find

The model on my dxdiag & pc wizard indicates that its an FX6800-01e But on my chassis it clearly says Model : Gateway FX6800-03h

Thanks for the source.

It recommended a 600W psu

But it depends on the typical game etc.

Battlefield Bad Company 2 requires a minimum of a Quad Core Processor with other specs. So i'm hoping to have a stable psu that will allow the video card to run at appropriate work. Since OC and Adding an extra GC i guess i should plan ahead on getting some kind of advanced cooling system ?

So im wondering in term of high end quality games like Crysis and the upcoming BF : BC 2 would a psu from W700-W850 do the job ?
 
So the type of mobo I get has influence on the type of PSU I get. Is this correct, because it sure does seem like it just because I know of my ATi Radeon graphic, it just tellls me that I can't get an SLi Nvidia PSU... Is this correct. And I'm wondering if anyone know where I can be explained the process of the mobo and how it relates to certain compoents such as the gsu psu and pro ?
 
For 2 GPUs 700W will be definately enough. 650W can be alright but system can go unstable if you have a PC that is in your signature

If your talking about my sig. then im 100% about my rig. Did all the possible research on odel number's and checked through pictures on other websites.

But i'm still confussed about what kind of psu's I cant add to my MOBO due to restrictions. And how the system work with restrictions.

*** So I got the pre-built cooling system*** in another post I was recommended to upgrade my cooling system(this is if I upgrade another gsu). Due to heat and noise levels of the 2 gsu's. I've heard that corsiar is able to keep its own psu's temper down with it huge oem fan. But would upgrade the psu and psu lead me into buying a cooling system aswell ?

Not all PSus are the same.

Something like that just opens my mind into the world of confussion. I will post the psu be4 I go into Upgrade Stage 1 with my psu and and gc. But from reading reply's and other thread's W700-750 is my range

that wattage is good. just stick to a brand like : corsair, silverstone, pc power and cooling, seasonic, OCZ, BFG, coolermaster, xfx, zalman,
 
seems to big fella there are other key components that my psu should have. Any type of obvious things that I should look at when observing psu's ? Almost everything he listed I dont even know what it is, or how to tell if it is solid quality, instead from comparing psu's.
 
Just a comment, many of the brands listed above make rubbish units so watch out!

The main points are:

  • EPS 2.91 cert
  • +80% efficiency
  • 50 amps or greater on the 12V rail (btw you cannot add multi rails up unless they have EPS. If not deduct rail 1 off the total)
  • MTFB at 40oC +100,000 hours (note the temp)
  • Solid state capacitors (they will say if they have it)

Look, essentially, you have a great system. The PSU however is probably the most important (and overlooked) component. Get yourself a Corsair 650W or greater. I would probably go with a 750W (i did) if you have the cash. http://www.newegg.com/product/product.aspx?item=n82e16817139006

Hello again. Gotta rebump this thread. But i've gotta say i havn't put much time on research or dedication into my computer because i've been really busy with my education & sport life.

Sorta wanna feed off peoples time so they can help me find the most appropriate psu for my system. I've got a couple already on this thread. So I was wondering If some1 could post some of there top 3 or 5 psu's that they'd use for my computer.
