Naah, ik ben een Surinamer. 250km is quite a distance for sure. And gas ain't cheap either.

Okay just realized that it is the GX I need to be looking at. The ones I linked to are of okay wattage but I don't know that they will be as easily converted.

Yesterday evening I bought myself 3 of these, they shipped this morning.

They look pretty identical to the one in this thread BUT I've just found that the one in this topic has model nr : 321632-001 and the ones I've bought are : 338022-001. Hopefully it will work *fingers crossed*. I will let you know :)

Nice. I did the same with two old server power supplies I got free from work. They're only 32a, but I only need one to get max wattage to my 208B.

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.

I got mine up and running last week... Thing sounds like a hair dryer! Prank your roommate by putting it in the bathroom for awhile!

It would probably be possible to open it up a little bit and use multiple quieter fans.. I might have a go at it.

Thanks for the post snellemin!!

The three victims:



Opening it up:



The noisemaker:


Possible solution?




I tested the PSU's shortly with my EOS0615i Duo2. When charging a 4S 5A pack with 5A/1C the voltage is at ~12.35, when I put it at 10A/2C the voltage drops down to ~12.17v and I will only charge at ~9.75A, any ideas? I saw snellemin's stay at 12.8v @ 25.4A:

I will ask at work if boosting the voltage is even feasible with this PSU. I have no schematic of what the other pins do. I was pulling 25A last nite out of the PSU and the charger stated 12.8V@25A. When I get a few more, I'll open one up.

Mine might be a fluke man. As long as it works right.

True, but I though it was strange that it only charged at 9.75A and not 10A ... Oh well I will empty some packs soon and try charging two 4s 5a both at 10A/2C.

Pardon me if I seem ignorant, but is there any way to use those power supplies to build something as powerful as this.

http://www.rivergatedist.com/bulldog_90.htm

I had a Rivergate PS years ago and I loved it. It was a 30 amp model which was perfect at the time. But although they are really good and powerful from what I remember, they are way too pricey.

Sure you can, but you will have to wire them up in series, which is dangerous if you don't know what you are doing.

You can also look at one of these - HP DL580/ML570 G3 Power Supply 1300W Watts Power Supply

I don't know what I'm doing so I won't go that route

I was thinking of wiring 2 of the 47amp power supply's up. I'm no electrical engineer, so how would your house hold 120 volt circuit handle almost 100amps of power? arnt most circuits in a house only 15amps?
