Psu Watts Usage

[CYBERSPACE]

How do you workout how much power you need for a computer.The mobo i will be buying is A8N-SLI PREMIUM i will be using 2 graphics cards when the price comes down.I was thinking of buying a SEASONIC S-12 600W i have tryed the calculator websites but still not sure which to buy,i would like to do some modding,and do 2 graphics cards use the same amount of power or twice the amount. THANKYOU CYBERSPACE

Take a look at this thread, as it has some good info and a calculator link in it

What is 230v equivalent to in watts??

 

[Me__2001]

you want 500W+ with about 35A on the 12V rail

 

[ChristopherP]

600w PSU should power most things

anyone know? on the back of my pc it says 230v.

Sorry I didn't read the first thread properly and see that you have already used the calculators, I'm with the rest and would go for 500W plus on a GOOD power supply (Tagan, Antec, etc...).

stuartw101, 235 Volts can't be directly equated to Power (Watts), but you can use P = V * I to calculate them if you know "I" (current).

230V is just the operating voltage, but there will also be a Power - normally, 250, 300, 350, 400, 500, 550, 600W depending on the unit.

 

[stuartw101]

So where would it say the power supply?

open up your case there should be a label on it with the rating

 

[stuartw101]

max dc output = 200w is what it says on the side of the PSU so i suppose thats right?

What do you think to this psu Enermax (eps 12v 660w)for this mobo A8N PREMIUM SLI NFORCE btw, do 2 SLI graphics use 2 lots of power or just one.

 

[Me__2001]

each graphics card needs its own power so adding a second card will be 2 times the amount one card needs

the enermax PSU's are good and that one should have plenty of power

Edit: ok just checked the specs and that has a total of 35 A across 4 12V rails which should be moe than enough

Could i use the Seasonic s12 600w if i wanted too i think it has 36A but not sure is this correct?..though it isn't 660w like the Enermax.

 

[PotGuy]

which cards are you planning on using?

nvidia geforce 6800gt or ultra, audigy xf1 fatal 1ty fsp edition sound card hi end or xfi platinum sound card, maybe a tv card, hope this helps.

yes, that will be able to supply more than enough power

 

[CYBERSPACE]

Thanks for that,im i right thinking the seasonic s-12 600w is 36A?and which brand and power do you recommend, thanks again for the help.
