12v AC/DC Transformer

gurusan · 14 Sep 2006 at 21:29

Does anyone know where to get one for a good price? I'm looking for one to power a few fans and a watercooling setup. What kind of amperage should I be looking for if everything will be using probably 30-40 watts?

To clarify...looking for a 240v AC to 12v DC transformer!

Are you on a mission?, try here

Why not just use the PSU?

Because I have quite a lot of components and I don't feel like upgrading my PSU.

And i don't see why I can't be shown somewhere else if OCuk doesn't even offer the product.

Something like a laptop PSU might be up to 30/40Ws and would be dead cheap to pick up.

You just have to be careful that any sites linked to don't sell things OcUK do too

The 500w PSU in your sig should handle the extra 20-30w load from a pump and a couple of fans, try this for quick check: http://extreme.outervision.com/psucalculator.jsp

Well is there any way to find out if your PSU is being stressed? I did the calculator and it goes slightly over 500 watts if I put my CPU to 3.2 ghz (allowing headroom)

I don't want to be pushing the PSU at full capacity obviously...so i figure offloading components onto a separate PSU would be a good idea.

BTW I will have 4 120mm fans, 1 80mm fan, 4 cold cathodes...an overclocked 7900GT, and I already have 3 hard drives, 2 in RAID 0....and a DVD burner.

Anyway the laptop adapter is a good idea i think I've found some suitable ones.

Thanks for all the help
