I was wondering if a 500w psu would be enough for this build http://pcpartpicker.com/uk/p/o1KE (Forget the gpu in this link)




This is the actual gpu ill be using http://www.scan.co.uk/products/3gb-xfx-radeon-hd-7950-d...


One last question is this all i would need to build a gaming pc?

And is all of it compatible with the other parts in the rig.




Thanks in advance guys :)

Eh, 500W is pushing boundaries. I'd get 550W or above just to be sure.

Can you recommend one that will work with that build?

http://www.newegg.com/Product/Product.aspx?Item=N82E168... This should be good. Not that 500W isn't enough, it's just that you always want to have an extra amount of watts that you aren't using. 50 extra watts is also good for if you upgrade CPU to a "K" series CPU (overclockable) and when overclocking your GPU, as I would recommend you do. Radeon video cards overclock like mad. Wouldn't be surprised if you squeeze 1.25 GHz speed core clock.

He did but it's in your other thread in International Forum. He was - erm - sort of - asking a question. :D

Yes that was a mystery. Since you came and got me though, here I am.

I would take the XFX over the Corsair in this case, but ideally if you spent a bit more you could get this Antec

I'm not quite sure why you would ever need more than a 500 watt power supply for a single GPU setup these days. Take for instance this chart:

http://www.anandtech.com/bench/Product/550?i=413.412.41...

It shows that under the most consuming possible power state the test machine was drawing 353 watts from the wall. If the power supply was 80% efficient it would mean it has to be rated to deliver 282 watts to the machine, which is only 56% of a 500 watt power supplies rated capacity. This leaves lots of head room for future needs as long as you don't want to do SLI/Crossfire in the future (in which case you probably want a 600w or higher to have similar head room in that build).

As long as it's not a 15 dollar "super ultra awesome high capacity 500w mega great" power supply, it should be fine.

so from what you can see is this a complete build and all compatible http://www.amazon.co.uk/registry/wishlist/3L467UJUOAWH4 (EXCLUDING RAM) still looking for decent ram on amazon :)

Why are you bumping things when they haven't even been posted for an hour yet?

Also, yes, that machine should go together just fine. I've never been a big fan of MicroATX boards unless you are specifically building a small-ish computer, but that's more a personal preference. I would have also chosen a board that support SRT, since I've been pretty impressed by the snappiness once it figures out your usage patterns . . . but again, mostly personal preference, and you don't even have an SSD to use it with.

On Amazon.co.uk it says the graphics card i want needs 500W :S

There is a PSU guide linked in my signature. I suggest you read it.

The XFX and the Antec are made by the same company and have similar designs. The Antec is perhaps a little quieter and more efficient, but the XFX has a longer warranty.
