Ok,
I've wated to build my own computer with a while (primarily for gaming but overall just to improve performance)

So far I've come up with this.

CPU: Q6600
Mobo: EVGA nForce 780i SLI
Case: Antec 900
Graphics card: XFX 9800 GTX+ (& with its price comes the potential for 2 more)
oh and a: Microsoft HABU Gaming Mouse

Im goin to reuse my old hard drive (Samsung SP2504c (250GB, 7200rpm)) and reuse my keyboard aswell as my monitor, 19" (will probably reconsider that though )
as far as OS goes ive convinced myself to get Vista ultimate 64 bit and a hefty amount of RAM to complement it

and i havent decided on a power supply yet.


So what does the internets infinite knowledge have to say about this spec?
any great value for money doo daa's im missing out on! or incompatibilitiyness i've overlooked?!
suggestion for power supply? (when i would actually end up with 3 graphics cards is uncertain so, get a big lump o wattage now or later or )
all your replies are appreciated!

You should get the antec 1200 if your heart is set on that type of
case. It will get real cramped in there, especially with two vid
cards. For power, I would be looking at something around 1000watts.
The last build I did was almost exactly what you are planning.
I think we used a thermaltake 1200watt psu., cant remember. But
I do know he used the antec 900, not enough room, very cramped,
and it go very hot with the power supply heating up the video
cards. Power supply directly underneath the cards. With a 1200
you should have ample room, but you still have the psu on the bottom
with heat rising....

G_Mach234

Is there no way around the heat issues? fan settings? extra fans.
i had my heart set on the 900, its cheaper than the 1200 and is a damn sexy case

manic

That case comes with alot of fans, looks real cool, but when you
cram 2 vid cards in there with all the cables coming out of the psu
it is a tangled mess. I was able to hide about everything, very compact,
but still hot. The psu is about 3 inches away from the bottom of the
bottom vid card. You need the 1200, if you like that style of case.
I just dont like the psu being on the bottom. Doesnt make sense,
we all know heat rises.

G_Mach234

Ahright, the 1200 is now under serious Deliberation

Any other pointers?
what do you think of my choice of graphics card etc.
also i forgot to mention i havent picked an optical drive.
any suggestions?

manic

You will like the 9800's but they do get hot. They all get hot,,lol
As far as optical drives , I usually use sony, not real picky bout those
drives, as long as they work. But if I buy one, I look for a sony, had
good luck with them over the years.
ps. I will tell you this, for the type of build you are doing you cant
go wrong with the thermaltake armor, not the small one the big one.
I think its a 6000, that was one sweet case, biggest case Ive ever
worked on. It was sweet. Plenty of room...Was a pleasure to work
on and in.....

G_Mach234

Thanks for the advice.
im now focusing on the power supply aspect.
would i be looking at 1000 watt?
3 GTX+ = around 700 maybe 750. ive nothing particualry interesting so 250 watt would be enough to cover everything else right?

manic

You will need around 1000watt. Especially if you plan on 3 in sli.
You will also have to pay attention to how many pci-e leads you
get with the psu. You cant plug just any connector to your video
cards, they have to be pci-e. Be it 6 pin or 8 pin. Those cards require
2 6pin pci-e connectors per card. The new cards ie, any of the dual
gpu cards require a 8pin, and a 6pin per card, all pci-e. The adapters
dont work most of the time, but keep in mind, even if you use a
converter, it has to be on the pci-e line. Ive been there done that.
You have to pay attention to this. Or else you will be on hold when
your system will not post, and you get to wait on a real power supply
that will power your system...

G_Mach234

thanks. so if im lookin for a future proof PSU then it should have at least 6, 6 pin PCI express connectors.
since youve been there, done that, can you give me a brand name maybe to go buy while browsing for Power supplies?
also im in ireland and am limited to 3 decent online reatilers (aswell as ebay) and they all dont have the very best stock. so the more mainstream and well known the product the higher the chance of it being available to me... all this help -> mucha appreciated btw.

manic

To be honest I cant remember the psu I used on the last high end
build I did. Customer provided all parts. But I do remember it was
a 1250watt. I think it was a thermaltake. Maybe someone else
will chime in, with a good solution. You also have to keep in mind
the 8pin connectors. The 9800gx2 requires a six pin and eight pin.
So do the nvidia 280's, and the 260's. So that looks like the way
the wind is blowing as far as power. I just dont want you buying
something that is not future proof, and lacking.....Research man!
lol
These connectors have to be pci-e!!!

G_Mach234

YES SIR!!!
lol but not now, its almost midnight.
ill spend tomorrow filterin through PSU's. researchin i spent 24 hours on that mobo, a WEEK on that graphics card and a couple hours on the CPU
(budget started to kick in then )

still though the threads open for suggestions concernin a PSU for moi

G_Mach234

So any suggestions for a PSU for my new build.
3 graphics cards in SLI. =P
so............ powerful :P

I'm getting a Corsair 750w PSU to run a HD 4870 1GB.. im sure thats plently.. but i plan on adding a second HD4870 in the near future, would i need a higher PSU for that?

G_Mach234

couldnt tell ya. probably but you also have to consider what else you have in your computer.

but anyway: PSU for tri sli quad core system! suggestions anyone!?

That's going to take a big bite from the wallet> http://www.pcpower.com/power-supply/...cool-1200.html

I don't really like the rest on the list except the Corsair 1000hx and I think you would be pushing it too hard.
