Rosbjerg Posted April 17, 2007 Share Posted April 17, 2007 Well I've bought myself a new computer (not the best, but dirt cheap).. following a lot of the sound advice I got from this forum. Now all the remains is the power supply unit! I've been looking at the "NorthQ NQ-4775-400 Ultra Silent PSU" which delivers 400W with reduced noise (which I like), but I'm wondering if that's enough? My com is a: P4 650 3,4 Ghz 250 GB HDD ASrock 4CoreDual-VSTA, MOBO 1gb DDR2 Ram Geforce 7600 GT 256 mb. My question is simple - how much W do I need for this humble build? Fortune favors the bald.

Deraldin Posted April 17, 2007 Share Posted April 17, 2007 400W should be plenty. You don't have anything in there that should draw a lot of power. Link to comment Share on other sites More sharing options...
mkreku Posted April 17, 2007 Share Posted April 17, 2007 Since the PSU is a very vital and future-safe part of the configuration, I'd suggest you spend a little extra on it. I would recommend a bZerk 500W. It's extremely powerful and is sure to deliver those 500W for real. It has detachable wires so you won't have to assemble more than you need (good for the airflow in your case). It's also very silent (I have the more expensive version and the fan on it has never reached levels you can hear without putting your ear directly on the PSU) and great value for your money. It's actually pretty cheap, especially considering the quality of the build. It might be a little difficult to find in stores though. Swedes, go to: Spel2, for the latest game reviews in swedish!

WITHTEETH Posted April 17, 2007 Share Posted April 17, 2007 Check this Power Calculator out Rosbjerg. It should give you a decent number. I would always get a bit higher wattage then what you need because not all power supplies are 100% efficient and you don't want to burn them out. Also for upgrades sake.

Rosbjerg Posted April 17, 2007 Author Share Posted April 17, 2007 according to the calculator (with every single device connected and running) I need a minimum of 352 W.. so 400 would do, but 500 would be on the safe side.

I checked the same place and was getting a much lower rating, but that's probably because I was missing a lot of stuff. Link to comment Share on other sites More sharing options...

Rosbjerg Posted April 18, 2007 Author Share Posted April 18, 2007 (edited) according to the calculator (with every single device connected and running) I need a minimum of 352 W.. so 400 would do, but 500 would be on the safe side. I checked the same place and was getting a much lower rating, but that's probably because I was missing a lot of stuff. I have some additional devices - like for instance a soundcard, some extra USB slots and an additional HDD.. Which all put together gave a higher needed value.. @Bok: The 1kW would cost me about half of what I paid for the entire computer - so I think I'll go with a cheaper 500W for now.

Remember: the PSU only draws what it needs, and a less efficient PSU will have to draw more AC from the mains (costing you more) to supply the same power to your precious innards.

mkreku Posted April 18, 2007 Share Posted April 18, 2007 I can't find it anywhere in Denmark .. what is the pricerange in Sweden? It costs around 750-800 SEK. As a comparison: I paid 1200 SEK for my 600W PSU from the same factory as the bZerk. Swedes, go to: Spel2, for the latest game reviews in swedish!

Also, make sure you have enough Amperes on each 12v and 5v rail. If I remember correctly, mine manages 530W on four 20A 12v rails (plus a 25A 5v rail and 24A 3.3v rail). That's guaranteed. Also, it has an almost 85% power efficiency so my Papst fan almost never has to work audibly (<20 dB). There are a lot of hidden factors in a PSU that can be pretty difficult to get a grasp on. Which is why I usually read lots and lots of reviews on tech sites before I decide on a part like this.. Swedes, go to: Spel2, for the latest game reviews in swedish!

Rosbjerg Posted April 19, 2007 Author Share Posted April 19, 2007 (edited) There's just too much information these days.. But I'll remember that the next time I buy a computer. It's just easier to rely on someone who spents every waking hour working with computers. Edited April 19, 2007 by Rosbjerg Fortune favors the bald.
