hi, im about to order a new system and wondering if the antec smart power 450 that comes with the sonata II will b okay 4 this stuff

evga sli motherboard
evga 7800 gt (not co)
1gb crucial ram (going 2 oc a little)
3800+ x2 (going 2 oc a little)
zalman cnps7000b hsf
nec dvd burner
western digital ide hdd
 
Marginal at best, but it won't hurt to try it.

If you are considering SLI in the future then the TP II 550W is for you. ;)

I think all you need is about 380wtts to run that system. You can even add another optical drive and hard drive in there and still be fine with 380wtts.

Check this website out.
 
If you want to over-clock and run SLI; you should look into a beefier PSU.

If you want to run with only one graphics card, you are fine.
 
Really?

I would have guessed that the 12V capacity of his ps would be well within what he intends to run on it. How did you figure that?

X2 & 7800GT + OC'ing = needs more room on the +12V.

It will probably work, but it is marginal & may limit his OC'ing. ;)
 
yea I noticed that he wrote a little oc next to the ram and cpu but not the videocard.

I meant numbers not like subjective terms...
 
We want a min of +12V@26A,
this PSU may not supply that based on the incomplete specs on the Antec website. :rolleyes:
OUTPUT
+3.3V +5V +12V1 +12V2 +5V SB -12V
Max. Load 32.0A* 30A* 15A* 17A 2.0A 0.3A
Min. Load 0.5A 0.5A 0.4A 0.4A 0A 0A
Load Reg. ±5% ±5% ±5% ±5% ±5% ±5%
Ripple V(p-p) 50mV 50mV 120mV 120mV 50mV 120mV
* +5V, +12V1, 12V2 and +3.3V maximum output: 440 Watts max
* +5V and +3.3V combined output: 150Watts

Also his mobo is SLI & there is no way this can power a highend SLI system.

and the reason you want that minimum is...

I think the guy just wants to know if it will work not if it meets some internet dudes check list of stuff you want in a powersupply.

How many watts (and on what rails) do you think his setup will use?

He hasn't ordered yet, he is seeking pre-purchase advice & that is exactly what I'm giving him.

I do not believe it is in his best interst to get a "marginal for specs" PSU,
that may require upgrading soon after purchase.

Now, I have no time to teach you PSU 101, please read the stickies.
I am here to help people, I have no idea why you are here. :rolleyes:

I'm here cause I sense that there are some people giving poor advice

Show us the numbers that prove this is a "marginal for specs psu"

(I'm not talking about repeating your minimum 12V claim, I'm talking about showing us how much those components draw and how their large draw pushes the limits of that powersupply)

What "good" advice would you give him?
 
I would read his post and answer his question according to the critieria that he picked instead of just making up stuff...

Please do just exactly that. Give him some "good" advice.
 
sure why not

ampedxc27, that ps should handle what you are considering

The "marginal at best" claim above has no foundation in reality and even the original poster has failed to provide any proof to back it up so don't worry about your current setup.

As for a second card, it may or may not work. You can search around and see actual numbers of SLI setups and user reports if you choose to
 
well i bought the system and if i want sli ill upgrade 2 a beefier psu in the future. thanks 4 the advice all :D
 
GeForce 7800 GTX (G70) Specs Updated:
Single card requires min. 400W PSU with 12V rating of 26A
SLI configuration requires min. 500W PSU with 12V rating of 34A
http://www.vr-zone.com/?i=2206&s=1
Click to expand...
Then updated:
Nvidia has lower the requirement for highend SLI to +12V@30A:
http://www.slizone.com/object/slizone_howtobuild_2.html
However, since we will be over-clocking, we will continue to recommend +12V@34A.

Here are the most accurate & respected PSU Calculators on the web &
they allow for OVER CLOCKING which greatly increases the power demands.

So when OC'ing is considered, we want a min of +12V@26A for non-SLI & +12V@34A for highend SLI.

so since vr-zone says that a single card requires a 26A rating on the 12V line means that it is true

interesting kind of logic you are showing us here

We both know what "requires" means so if I were to show you examples of that video card working with a psu that is rated lower than that the statement would be proven untrue

You are not here to help anyone, just to argue!

If you were at DFI-Street I would ban you!

Dave :mad:
 
hey

sorry you feel that way guy

its just that I saw you giving advice that wasn't correct and I called you on it. I don't see why you should get so upset over it. Why do you care about it anyways?

If you really want to help others here than you should be open to valid criticisms as that would help you/others find out what really is true or not. It doesn't help anyone when someone just clings onto one belief without being able to support it when someone points out an error.

I don't think banning would help either because then people who understand this stuff would leave the forum cause they would think that it is just to stoke the egos of those who run the forum versus trying to learn
 
You education or lack there of, isn't or atleast shouldn't be my problem.

My advice was the best possible & I stand by it.

You need alot more experience & knowledge. I hope others don't suffer while you get it.
 
thanks for throwing in the insults while making assumptions about by education

I'm sure everyone is impressed with how you handled yourself in this thread...

You consider this to be good pre-purchase advice to someone with a dual core CPU,
7800GT, an SLI mobo, who says they are going to OC?

An "economy" Antec SP II 450W is not a good place to start given the above system,
which will become a highend & OC'ed SLI rig.

If you think it is, you are entitled to your opinion.

Good Luck,
Dave ;)
