380w for my setup ?

Post by acidoangel » Mon Nov 09, 2009 1:29 pm

Hello,

Actually I got a NSK3380 with 380w power supply.
The power supply is moded with swapped fan + 92mm fan on the top.

My current setup is :
-Phenom II X4 [email protected] (originaly 550 x2 with 4cores fully activated)
-SSD Crucial 64Go
-HDD 640go caviar blue
-Graphic card : HD4850 1go

But I want to change my graphic card for a new HD5850.

I don't know if the 380w will be enough.
If not, what power supply can I pick ? I have already tried : HX620 (wistle),HX750 (loud), MODU525+ (loud fan). Maybe the new HX650 ? or VX550 with swapped fan ? ...or OCZ Z series 550 ?
...I'm totaly lost...

Please, help me.

Thanks,

Acid

If the PSU is OK with your current card, I think it will be fine with the new one. The 5800 series seems to have lower idle and the max is only marginally higher.

Thanks for your response.

But maybe 380w is not enough in "long term" ?

Today, I'll try to take some watt measure of my current setup.

And I've another question which is the best between HX450w (with swapped silent fan) or Nexus Value 430w (or the new nexus NX5300R3) ?

I tested with my config and my new 5850 with oc 775/1000.
I've approxtively 220w (360w with occt power supplies test) during Risen game and 110w in idle.

So my 380w is enough...

What is occt? Why the 2 different w numbers?

OCCT is a app to stress both graphic card and CPU ( http://www.ocbase.com/perestroika/index.php?Download ).

It's can be useful (but dangerous) in order to test power supply to their maximum...

With some others test :
Oblivion : approx. 220W
Risen : approx. 225W
Grid : approx. 265W
Crysis : approx. 270W

I take this measures at the entrance of my power supply, so I need to remove (approx) 20% in order to got the true consumption of my PC.
