How to build a $20 47A power supply

[kazuaki]

Thanks for the info. I've got mine up and running.

I soldered on some power leads and made a jumper from servo leads to short out pins 6, 8, and 10. This jumper stays in place all the time.




The reason I can leave the jumper in place is because I added a power switch to the input side.



So far, it seems to work well...

Any pics on how you did that?

I received my three PSU's today. All three work flawlessly. :)

How do you shut down the PSU, just by pulling out the power cable? The fan makes a noice that is freaky loud ... definately need a solution for that. The PSU itself is also WAY smaller than I expected, even when I knew the dimensions...

Will post a pic tomorrow, going to solder some leads and stuff now. Thanks for the tip, this saved me a nice buck.

Man those output cables look massive!

Q: the input power = a US connector?

If I would buy one I would need to get myself a converter, or a cable like that.

The power supply supports 240AC. You just need to get the proper cable for it. I have some laying around here.

To those that have been using this a while...is heat even a concern the way we are using these? I'm just wondering about stepping down to a slower fan. The one in this thing is insane, super loud.

[ANGRY-ALIEN]

Yeah... that fan screams man... i think the design and layout of the cooling system was really because of its intended use... stuck inside a hot blade server running for countless
hours allowing them to get a little warm... I am guessing since we have them out of those hot, cramped spaces they are 'use to', they'll run much cooler... so if you have a fan that will be
quieter and can still move a good volume of air through PS... it should be fine... run some tests and make some comparisons with temps...

These PSU's are nice, easy & cheap! Thanks Snellemin!

That is what I was going for.

Here's a pic of the Europlugs that I have laying around.

[Nard Cox]

Yeah, stupid question. Shouldn't known it's just a normal plug, those things are universal. That's indeed the euro plug like we have.

Concerning the fan. Perhaps make a air-conduct and mount a 120mm fan on it. They can run slow (be quiet) and still move massive amounts of air.

OK, I've ordered myself a new Hyperion EOS0615i Duo3 for 170 euro / $225 shipped (not a bad price, not even compared to US prices).

So I'm looking into a PSU again and I typed this model into ebay.de and voila.
But it's more than four times as expensive and it's a USED model.
$65 incl. shipping to NL and $50 to Germany.

So if anyone has some cheaper suggestions let me know.

Nardos! You bought yourself a Hyperion Nice!

Someone from the States could bring it to Holland en dan kan jij het dan ophalen.

[Nard Cox]

Sounds like a good plan, wanneer kom je naar Nederland?

Just found this used one, $41 shipped to the Netherlands. The prices they ask are suprisingly far apart. I found a Dutch shop who charged $250 for this PSU.

Mijn schoonmoeder is hier, maar ze gaat pas eind van deze maand terug. Ze woont in Breda.

$41 isn't so bad though, compared to some power supply's that get sold here for 150 http://www.amainhobbies.com/product_...-138V-40A-520W
