AC to DC

[Luke32800]

what is the cheapest ac to dc adapter that can output about 240 watts? 300 would be ideal, but 240 would still get the job done.

What kind of voltage are you wanting to produce?

im not sure...

im trying to power this power supply, which has two slots for ac-dc adapters: http://www.aliexpress.com/store/product/Free-Shipping-X7-ATX-400-400W-High-Power-24PIN-DC-ATX-Power-Supply/211500_747813627.html

Found this by typing 12v 240 watt into ebay:

I suppose you could wire something similar to that up to whatever you're powering. It shouldn't cost $90 though.

What are you wanting to power with it?!?

 

It's got a pretty nice input range, lots of laptop power supplies would work. I'd question that 500Watt rating, thankfully it's the Peak rating (still questionable). Let us know what you want to use it for and I'm sure we can find something to suit.

What's your PC got in it? Does it currently run a 500W PSU?

it could run on as low as 300w, according to pcpart picker

I mean, if that board can really take that much current, then by all means...

Just, what is stopping you from using a normal ATX power supply?

im trying to make my computer fanless, but the case is quite small.

Well you could've told me...

 

Just buy a normal power supply. You won't be able to power a computer without a lot of issues.

 

Buying a fanless power supply is expensive buy if you really want one, it might be worth it.

 

I'd just get one with a really quiet fan.

I can feel myself starting to cringe a little. I get where you're going with this now, just I'm not convinced that PSU (which admittedly isn't having to do the rectification from AC to DC, and large transformations) is really up to the task. Under general load, yeah.. But strain is going get that puppy hot with no cooling solution other than passive.

 

Talking fanless, what are you doing about the CPU?

wow... reminds of the Coolermaster V10 (without the fan of course). I guess you can give it a go - unfortunately the PSU I quoted above does have a fan in it - they aren't on continuously though, on when it gets hot. I'd still be a "fan" (get it) of moving air through the system though.
