The ultimate PSU chart I have ever seen....

[Duvie]

Thought I would share a link with you guys.....

My systems even calculating OC'd cpu was 388 watts...

cpu was 153 wwatts....

Edit: side rant...

temporarily removed cause I mistakenly thought a 520 OCZ was dual rail....I will find new proof...

 

[Duvie]

Also keep in mind those are all max loads so the wattage would be if you were using everything or basically worse case scenario.....

Good find ! My X2 system needs 332 watts. I think my 380 true power is fine.

 

[brikis98]

nice tool. my system needs 332W, the True 430W should be fine

btw, i wish there was a similar tool that could tell you what kind of drain you could expect on the +12V line(s). i think that would be more useful, since many ppl neglect the +12V line and focus too much on a high overall wattage PSU.

I have my main computer Over clocked at 30% over the normal clock speed with no issues!!

Personally I don`t use dual 12v and I don`t buy into any arguments for or against the dual 12v!!

When it comes to over clocking you have alot of people who go both ways concerning dual vs single 12v PSU`s!!

Then you have those who insist that dual is the absolute 100% wave of the future!!

I have read nothing stating as an absolute fact that dual is the wave of the future....

Then again we saw how RDRam came belly up.
Was`nt that also suppose to be the wave of the future??

heheee

hey, shuddup, i once bought RDRAM!

as for dual (multi) +12v rail, it does seem like a good idea in that it prevents any one rail from being overloaded. as for actual performance, don't know, never used one.

while i agree with you on the dual rails, isn't the powerstream 520 single rail?

 

[Bona Fide]

According to that, I'm going to need 435W. Will an Antec Smartpower 2.0 450W be enough? Or is that too tight?

Yes it is.

how many people are actually going to use over 200w on the cpu 12v rail though?

 

[Duvie]

If it is I am shocked....I thought it was dual 12v rails....

Edit: you are right...it says 33a on the 12v...I guess I should STFU....I will go to extreme and bring back 3-4 of some of the top OCs and many are using 600watt OCZ like mine which has dua power rails....

You can see if my load is 153watts and my 12v1 rails is 20A that is 240 watts delivered on that rail...even with efficiency levels I should still deliver a minimum of 168-192watts....my vid card according to that chart is only 80watts so I dont see it overwhelming the second rail either....

 

[Diasper]

Pretty good although it could benefit from estimated Amps on each rail. Of course some motherboards do things different eg RAM on the +5 or +3.3

maybe i'm misunderstanding this stuff as i'm certainly no expert.

i thought efficiency was from ac->dc. for instance, if you're pulling 500w from the wall and you have an efficeincy of 75% you psu would supply 375w of power. or in order to supply 500w to your system, it will draw 625w from the wall.

i think what you mean is the heat loss or whatever it is called.

my max 12v's if each were fully loaded is rated at 18a each at 25c. so if i lose 2.5w/c above that and my psu is operating at 50c i would lose 62.5w per rail. so 216w - 62.5= 153w available for my cpu 12v.

according to the calculator, my sandy at 2750 would draw 115w, obviously plenty left over.

maybe john can help us out here.
