Any standard size atx power supply will fit.
Top brands are, corsair, antec, ocz
Go to power supplies section on retailers websites like newegg etc, look through reviews from buyers.
Narrow down a few power supplies you like and google for professional reviews on them.

Corsair/PC Power&Cooling/XFX/Seasonic/Antec/Silverstone/NZXT a few others depending on the model.
Offtopic, but somewhere I saw that real values r these, is it true?
430W @80%efficiency = 344W
450W @80%efficiency = 360W
500W @80%efficiency = 400W
550W @80%efficiency = 440W
600W @80%efficiency = 480W
650W @80%efficiency = 520W
700W @80%efficiency = 560W
750W @80%efficiency = 600W
800W @80%efficiency = 640W
850W @80%efficiency = 680W
900W @80%efficiency = 720W
950W @80%efficiency = 760W
1000W @80%efficiency = 800W
430W @80%efficiency = 344W
450W @80%efficiency = 360W
500W @80%efficiency = 400W

Havent we already discussed this????
No this isn't true. Efficiency doesn't work that way.
A PSU rated at 500W continuous @ 80% will still provide 500W but will draw 600W AC from the wall to provide the 500W DC.
Ive already explained this to you in detail here http://www.computerforum.com/223798-card-psu.html#post1886578 so please read the responses to your questions and when providing nonsense like the above can you please at least provide a link.
Sheesh - off topic and already answered = slightly frustrating.
Exactly. What hardware is this machine running which warrants an 800W PSU? Chances are a good 600 or 650W unit would suffice perfectly.
This was the first time I posted this board.
I dont remember the link. It was just a poster.
Exept u, no one else exist here? I heard your answer but lets hear other people as well.

I gave you the link, you asked exactly the same question, which was answered not only by me but others, and its not an opinon, its fact, science and unrefutable. So please, don't hijack this person's thread with questions you have had answered. If you don't believe me, then go back to your thread, and ask someone else there.

Oke is right....your efficiency is the power you pull from the wall vs the power you pull from the supply. Its not a opinion, its fact.
Which link u gave me? I repeat that this was the first time I posted that board. I dont hijack, I support the thread with similar question. It would be a good idea to support it too, instead of useless blabla about my other thread. I believe u but I also believe other people too. U r not the only truth in this planet, u know.
So, any noname psu which call itself f.e. 700W is always 700W?
Which is the reason for someone to buy a well known firm instead of a noname?

Nobody is questioning that its not a good idea to get a noname power supply.
Its your chart above thats incorrect. The amount of wattage and the efficiency has nothing to do with each other.

You have 146 posts. I put the link in my response where is says card+psu. But if you didn't see it here it is again:

You asked the same question in that thread and it was answered.
Regardless, your suggestion regarding efficiency is wrong. Fact, and has nothing to do with the OPs question in this post, so yes, its highjacking. You even started it with "offtopic". If its offtopic, and already answered, you're either trolling or hijacking.

You mean that its a good idea to get a noname psu? U prefer to get a noname psu instead of a well known firm, with the same money?
Hey, whats the matter with u? U insist to make useless posts about other threads. In the other thread I did not post that board, its the 3rd time I mention it.
My question is similar to op's question. I m supporting the thread. I m afraid u need support to your brain

and now this
You asked this previously (AS LINKED). What the hell are you on about? You have asked if efficiency works the way you proposed here http://www.computerforum.com/223810-new-power-supply.html#post1888949
SAME BLOODY QUESTION!
NO, THE ANSWER IS NO! OK? EFFICIENCY DOESNT WORK THIS WAY AND NEVER HAS!
So stick to the OPs question which HAS NOTHING WHATSOVER TO DO WITH YOUR MEANINGLESS DRIBBLE AND EPICALLY POOR ENGLISH>
Please, pull your head in and stop asking (frankly) stupid questions.
I'm beginning to think you're a troll.
If you read what I said, its not a good idea to get a crap PSU.

I dont really know why your not getting this. Will say it again, the amount of wattage on a rail and the PSU efficiency has nothing to do with each other, nothing.
OkedoNkey, u became really annoying and boring.
I asked u several times to stop that useless blablabla about other threads. U insist...
I wont waste more of my time with u.
PS.
First of all, its your honor that I accept talk in your language.
Second, I dont need to use Oxford's english to talk with people like u.

Wow...I came here to read the thread "new Power Supply" and found a big fight between you people.
Everyone shut up and calm down lol.
Come on lol.
Dasos if you have ANY questions,you can always make your own thread.But as Okeydokey already said...he gave you an answer on your questions...one more time here is a link (the one he already gave you):

Also a no-name power supplies are not always bad.I bought a no-name power supplies few times for JUST 26.12 dollars.They were 420W and had up to 25 A on 5V rail and 15 A on 12V rail.I was able to connect ALL my hardware and add up to 8 hard drives.It ALL worked perfectly with no problems.Not bad at all for just 26.12 dollars!
Not to mention that it had PASSIVE PFC.The ones with ACTIVE PFC are better of course.
That PSU was used on my new second computer which has a LOT stronger hardware than my main computer so that no-name PSU for just 26.12 dollars did one hell of a job.
What I am trying to say is that if THAT cheap no-name PSU did such a great job then I am pretty sure that a good brand name PSU of let's say 650 or 700 W will be more than enough for you if not even too much.
Just take note that WATTAGE is NOT THE ONLY thing which is important when buying PSU.If you are (for example...) going to use your PSU to connect let's say...10 hard drives on 420W PSU...420W seems MORE THAN ENOUGH for just 10 hard drives if each one needs let's say...6.19 watts.
HOWEVER if each one of them needs 3 amperes to work properly and the 420W PSU offers 15 amperes on 12V rail then all 10 hard drives will NOT work.
So if the PSU is even 800 W but with only 15 amperes on 12V rail then the result will still be the same.
Hard drives have platters which spin at BIG speed such as 5400 RPM or 7200 RPM or even up to 10000 to 15000 RPM.And motors which spin those platters need POWER in order to work.This is where 12V rail comes to do the job.If that 12V rail has enough amperes for all 10 hard drives then all 10 hard drives will spin and work okay.Otherwise you will experience a power issue.
Then we have a 5V rail.That one is used for the HDD logic and does not need SO MUCH power like the 12V rail since it doesn't use those motors which spin the hard drives at huge speeds.
So if you want a good PSU,you MUST pay attention on everything and not just the WATTAGE.
I noticed that Ralfo is the original poster and still haven't answered lol.
Ralfo my man you there?!
