Is this PSU enough

CORSAIR CMPSU-550VX

 

with...

 

• BIOSTAR TA785G3 AM3 AMD 785G Micro ATX AMD Motherboard
  
• HIS H575FN1GD Radeon HD 5750
  
• AMD Athlon II X4 620 Propus 2.6GHz Socket AM3
  
• Western Digital Caviar Blue WD5000AAKS
  
• Sony Optiarc 24X DVD/CD Rewritable Drive
  

 

I'm just concerned because the CPU is 95W, the graphics card is 450W, and the PSU is 550W, leaving only 5W for the rest of the thing.

 

Well this is what it says on newegg for the graphics:

450 Watt or greater power supply with one 75W 6-pin PCI Express power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX technology in dual mode)

Which one of those (450W, 75W, 600W, 2x 75W) is the actual drain on the power supply? And is my PSU good enough?

 

 

Side note: what is crossfire?

Ah, my recommendation.

 

Yes. The Corsair VX550 is easily enough for that, you could use an i9+GTX260 without fuss with that psu.

The graphics card does not suck up 450w. AMD states 450w for graphics card+whole build so it works with crap psu's aswell.

 

Crossfire (SLI - Nvidia) is when you use dual gpu's.

PSU will be fine, easily.

Not quite, you can use two graphics cards at the same time and still not use Crossfire or SLI, I do this so I can support three monitors. Crossfire or SLI combine the processing power of multiple graphics cards, using only the ports of only one of the cards. This means you can have two cards processing the images on one monitor, with nearly twice the processing speed.

You don't think i know this?

Maybe you did, but using two GPUs isn't the same thing as SLI. All I'm saying.

Hah.

I think most people understand what i mean. So i forgot a couple of words... Blabla.

And twice the speed, not really for the majority of the games. Even tho it's soon 2010, dual gpu's are still badly optimized in games. Some games you can almost get x2 the power, but on most, no (modern games).
