which psu should I buy...

I currently have a Acer Aspire M5500-1E77.
That means: q6600, 8600 gt and as psu: a ATX-250PA (1PF).
I'm planning to replace my 8600gt with a 8800GT 512MB.

I'm just wondering which PSU I should buy. I can't find any specifications on the internet of psu's and I don't really know much about computers. Could somebody help me with this?

CoolerMasters are great.

Cheap, reliable, quiet and efficent.

I have a Extreme Power Duo 650W, and its whisper quiet, and well ventillated - not to mention it was cheap.

The Corsair 620 watt is a great supply. I love mine.roulettethedog

Ill second that, mine is great.

And which specifications should the psu have, if I want an 8800gt 512MB to run at its full potential?

650w but 1000w so you wont have to buy a psu when a better compont comes out. i have a 8800gts + the new intel e8400.

I'm not planning to upgrade any further, so a 650W should be enough? And I read some stuff about 20+A on a 12V-rail or something like that. How many amps should that 12V-rail have for a 8800gt? And does it matter how I connect the components to the psu?

Corsair VX450W will be more than enough for your system and it has enough amps on +12V rail

sorry to butt in but what is the modular psu...:question: anyway i'll say corsair or silverstone is good 550w and abovexdeer

Modular means that you can remove the cable you don't use from the PSU

How much watt and amps should it have exactly? Because i just want to buy a psu that is available in one of the local stores. And here in Belgium, I can't get that Corsair VX450W...

Add up the watts all your components use, then add about 150 at least to that (I'd go higher), and select an 80 Plus rated PSU.

And make sure it has cables / connectors for any cards that need them.

Go to your store and tell us what do they have in stock for PSU > 400watt then we will see which one is better for you because we can keep you opinions and suggestions but you might find none !!

Quick question since its on this topic.

If you need 20 Amps on the +12V rail will a PSU with 2 +12V rails with 17 on each not work?
