Re: EnerMax Galaxy 1000Watt DxX

Glad to hear it worked. Funny thing is I replied to this thread last on 3/20/12 it's 3/20/13 today.

Hooked to your computer??

Re: EnerMax Galaxy 1000Watt DxX

I plugged it in and nothing blew up! HAAA............

Thanks guys!
I'm gonna hook up and old dual core with a couple old video cards, see wat happens

Re: EnerMax Galaxy 1000Watt DxX

That's exactly what I thought when I saw that PS-ON switch

That one is actually quite OK, but the inner +12 V switches (for them four bulbs) or the +5 V switches for the resistors there, thats some challenge with all the fans and 200°C light bulbs

Another way is with several 12V to 120 VAC inverters. There's plenty of "power-hungry" devices to hook up on 120 VAC. However, building or buying an adequate inverter to handle that power is not as easy either. But that's probably beyond the scope of this thread anyways .

I do not want to use any active devices, it may further interfere with ripple measurements. I have enough problems with that even now

But it think it belongs here just fine, we needs to load this PSU with 1000 watts don't we?

Re: EnerMax Galaxy 1000Watt DxX

For example it is NOT good idea to place any switches inside, it's horror to switch them

That's exactly what I thought when I saw that PS-ON switch

Yeah. For that reason I am planning to use resistors in TP247 (or similar) package mounted to heatsinks on my next generation load. You can pretty easily waste around 100 watts at very small space consumed here if you keep them cool.

Re: EnerMax Galaxy 1000Watt DxX

Is that the load-tester with the NTC thermistors you made? If so, it looks pretty nice.

Yep and thanks Got some feedback of how not to do things when I'll make it next time. For example it is NOT good idea to place any switches inside, it's horror to switch them

I was going to suggest an old Pentium 4 computer, but I see I already made that suggestion on page 1. Another alternative to that could be this:

2 or 3 of these on the 12V rail should load the PSU quite nicely. If the PSU makes it alive with this load, it should be fine with any computer then since even most high-end computers won't use more than 400W on the 12V rail.

The only possible problem with the above PTC heater is that the cold resistance is not stated. If it's too low, it may trip the short-circuit/over-current protection on the PSU.

ADD// or maybe some babies like these http://www.digikey.com/product-detai...R00-ND/1743008 They are very precise and with this exact model, you can leave it up to arround 130 °C and it will still dissipate the heat (144 W) fine. So you don't need that big heatsink and/or fans if it can cope with 144 W at 130 °C (taking it from derating curve)

Re: EnerMax Galaxy 1000Watt DxX

I am using halogen lamps for +12 V and resistors for other rails. Made it a little bit more mobile.

Is that the load-tester with the NTC thermistors you made? If so, it looks pretty nice.

So its all buttoned up and I wanna test it, But do not wanna lose my socket 2011 board on it. I wanna test this THOROUGHLY as I will be using my own stuff with it, and I'd rather melt it down now then with a good build computer.

Problem is for 1 kW you'd need way too many such components and also fans so I am afrraid you won't be able to load this thing to 100 %.

Re: EnerMax Galaxy 1000Watt DxX

Hello All!

Long time, do to personal issue's (my ex girlfriend) I didn't have a chance to finish this thread...........

So anyway a few months latter, I had finished the unit before I moved. I'm fairly confident in my workmanship, though a few of the traces seemed VERY close to one another. I used Petroleum Jelly to make my solider flow, had to use a heat gun to make the solider melt on the BIG connections.

So its all buttoned up and I wanna test it, But do not wanna lose my socket 2011 board on it. I wanna test this THOROUGHLY as I will be using my own stuff with it, and I'd rather melt it down now then with a good build computer.

So please a GOOD Test procedure for this beast, I'm scared to even pull it in!!!

I'll b doing that right after posting this,
Again Thank you all for your help!!!

Re: EnerMax Galaxy 1000Watt DxX

Yes Panasonic is definitely good but you could also consider Nichicon and UCC (United Chemi-Con)/ NCC(Nippon Chemi-Con) [same company 2 names].

For those CEC TULs I'd go probably with the following for replacements.

Nichicon: PW/HE
UCC: KY/KZE
Panasonic: FC/FR

All of these are good long life low impedance caps. There are few specs available on the CEC caps that the Enermax came with but from what I have heard the TUL series is entry level low impedance specs wise either equivalent to or slightly worse than something like Nichicon PW, any of the above listed caps should meet or exceed the specs of the caps you are replacing. I usually use UCC caps for PSUs since they tend to be lower priced than Nichicons or Panasonics but on a small order (enough to do one PSU) the price difference will be minimal

Thank you dmill89!

2 16v 3300uf - these (if you can't squeeze 12.5mm dia caps in) or otherwise, these
2 10v 4700uf - these if you can use 12.5mm, otherwise, these (Yes, I know they are 3300uF, it will work fine - the 4700uF rating on the originals is bogus if they are 10mm diameter)
2 10v 2200uf - these
4 16v 1500uf these
2 10v 100uf - these or these

Cool cool!
Ordered, got to wait it out.
Thank you C_hegge!

Re: EnerMax Galaxy 1000Watt DxX

Cool!
yeah these are the caps:
2 16v 3300uf
2 10v 4700uf
2 10v 2200uf
4 16v 1500uf
2 10v 100uf

That transistor did have marks on it they are : FOR3G then under that it has "7.C" I assume that's not to hard to find. So Panasonic is good, will it be OK for all of them if they are Panasonic? I want to use this on my stuff for a few more years, also I over clock too so if need be I'd like to beef it up a bit even if that means replacing other parts, so long as I don't lose more stuff to it again.....................
Thank you hegge!
Update here's my shopping cart wanted to make sure it looks good, I'll get the transistor from digiKey.

Re: EnerMax Galaxy 1000Watt DxX

Try http://search.digikey.com/us/en/prod...OSCT-ND/964539

It's not hte same model, but I think it will work as a replacment.

Re: EnerMax Galaxy 1000Watt DxX

Hegge,
Can you link me to a transistor at DigiKey, I have a hard time finding anything there the markings are " FOR3G 7.C" on the resistor.
Thank you!

[Philly Cheese Steak]

Re: EnerMax Galaxy 1000Watt DxX

Those caps look like either 3300uF or 2200uF 16V in 10mm diameter (at least some of them do). If they are 3300uF, then these (https://www.badcaps.net/store/produc...products_id=56) are the only reliable caps which will fit.

If you have 2200uF 16V or 3300uF 10V or 6.3V in 10mm diameter, then I usually use Panasonic FK series (which I think are available from digikey)

Cool!

Cool,
I'll try, got sick today plus work, so not had a chance to mess with it. Can you suggest good caps, I lost the link I had for them?

Thanks guys!

Re: EnerMax Galaxy 1000Watt DxX

ahh, well you will need to read the numbers off it so we can actually tell what it is.
