Upgrading to a Core 2 Quad, Do I need a new PSU?

Ok right now, I have a Dynex 400W

http://www.amazon.com/Dynex-DX-400WPS-Watt-Power-Supply/dp/B000X1R5HM/ref=sr_1_1?s=pc&ie=UTF8&qid=1327449007&sr=1-1

I believe,

So I'm upgrading to a

Core 2 Quad Q6600

and a

Sapphire Radeon HD6850

Now, I really think I don't have a good enough psu, but I don't have too much money to spend. so Im looking for one around $50 that is compatible with my system(775 socket) does anyone know any good ones?

  1. In my opinion that psu is perfectly fine and will work fine with those two peices of hardware i have a Core 2 duo e6750 and a hd 5570 and a 330w cheap psu and it runs fine.
  2. no you need to get a new psu. That dynex psu is really crappy.

    you can get a cx430 for $40 on newegg which will work. something from corsair or antec is good for low end. get one above 300 watts.

    That's what i thought, is there any specs I should look out for, especially when it comes to my gpu? I want to make absolute sure it will be compatible.
  4. you should look for a psu from a good brand(antec, corsair, seasonic, ocz) with an 80+ certificate, also one that has a 6 pin connector for your 6850. Make sure the psu can deliver at least 30A down the 12V rail(s).

    as for the motherboard, any psu should work with the motherboard 775 socket motherboards are pretty standard.
  5. Oh i didnt look at the actual psu you had, yh as esrever said you will need a new one, that dynex one is a really poor quality psu
