How much PSU watt?

[AncientBro]

Hey all,

I was wondering how much PSU watt is needed for this system (It's for heavy games)
My dad said that he wanted an as low as possible PSU because of the electricity bill.
So how much Watt is needed for this system to DON'T bottleneck when playing heavy games or heavy applications? (Like, Skyrim, Battlefield 3, Assassin's Creed 3)
Here's the PC:

550W should be plenty.

having more watts on the psu wont really increase the amount of wattage pulled from the wall

ie, if you have a 700 watt psu but the computer only uses 350 watts, you wont be drawing 700 watts from the wall. you will be drawing closer to 350 watts.

infact, there is something to be said about efficiency in this regard. a psu drawing only 60 percent of its max will actually draw less power from the wall than a psu running at 90 percent. ie, a 700 watt psu supplying power for a computer that requires 500 watts will typically draw less power from the wall than a 550 watt psu supplying 500 watts.

efficiency varies from model to model and the amount of power being drawn off of it though.

Make sure to get a reputable brand. Corsair, XFX, Seasonic, Antec, certain Rosewill

Any quality 500-550 should give you more then enough power for your system.

It is important to know that a pc power supply only takes as much power as it needs so even a 800 watt power supply would not waste much more power(maybe even less if it a higher efficiency one). Just for example, My media center has a 300 watt power supply and pulls about 40 watts idle(right now) and my gaming system has an 850 watt power supply that has yet to pull much over 350(and to get that I have to push it way harder then just gaming).

Now you also should know the biggest thing you want to see is how much power the unit can deliver on its 12 volt rail(combined[not just adding rails] rating for multi rail units.).

Well that moved quick

a 450watt+ quality powersupply would be good such as this.

59 euros high quality, made by seasonic and rebadged as xfx, cant go wrong with this.

I don't live in the USA, I'm trying to find that product on a Dutch webshop.

Thanks for your reply, but the link doesn't work

er ok here.

I'd recommend at 650W...costs the same as 550W...for the obvious reasons Neon sated above. I could not said it better Neon.

 

[iceclock]

the 550watts is fine.

but if the 660 is same price get that one.

 

[AncientBro]

Is 520 watt enough? Otherwise I'll take the 620 SeaSonic: http://azerty.nl/0-1073-280719/sea-sonic-m12ii-620bronze-.html

 

[AncientBro]

er ok here.

That one isn't modular, right? If so, that means that it will prevent full airflow because of the lots of cables.

Will that one do? It's Aztec

 

[maxinexus]

It does not mater if it is modular or not. I have a modular and I'm using all cables anyway.
Airflow should not be affected much. There are ways to micromanage the cables as well

Specs you provided show a 210-220 watt system, stated earlier; a quality 450 would be enough, 520w is a good deal more than enough
