As for the units you linked.. again, except for the M12II B which is well priced, there are better deals to be had on newegg, on equally good or better units, than everything else you listed.

Ok Im just gonna take your word for it as Im not a psu expert but from what Ive seen on power draw tests and such Ive seen otherwise. And I agree there are better deals I was merely linking him to quality power supplys.

Keep in mind that with the exception of TPU, every other VGA review site on the web reports power at the wall, not DC draw.

There's a sticky on this very section of the forum created by AMC and called "Real world power usage (User submitted values)", check it out, it might clear up some stuff for you.

However, even if the OP's system will draw about 450-500w, there's no reason not to buy a bit higher rated PSU. There's other thing to take into consideration since not every 500-600w PSU will be able to sustain that kind of power for long period of time. A top notch 550-650 is what is needed even if the system don't draw that much power.

In order to be a bit future proof my suggestion would be get a good 750 -800W PSU

My personal favorite it PC Power & Cooling 760W Silencer PSU, It can be had for about $100.
Its not modular but, that thing is a beast. I am pretty sure its 80+ silver

It has plenty of connection. And a 7 year warranty !! What more can you look for. smile.gif

Thread Starter 
Thanks very much everyone, i've taken everything everyone has said into consideration and i'll be buying a 550-650w PSU, whichever I can get for the cheapest that is a good brand like Corsair and 80+ bronze smile.gif --oh and the "Real world power usage (User submitted values)" thread is very helpful, so thanks again Unoriginal Sin for recommending it and Denial_ for having it in your sig so I didn't have to search for it biggrin.gif

EDIT: Oh yeah I added to your reps biggrin.gif

System spec in my sig pull about 428watts @ approx 83% rate on full load CPU and GPU. So that's about 515watts actual output from PSU. My GPU is requires 550watts.

 

@OP your system will not be as power hungry as mine anyway. 600-650w PSU is enough for single card. SLI 750-850 watts (assuming running only 2 GPU in the future + smaller die = less power consumption.)

Not really, every decent 550W unit on the market should be able to deal with that load quite comfortably.. if you're going into the high end segment.. then a 500W unit would be sufficient.
