This power supply is a cool find - just ordered, as it was the last item needed for my build - banggood are out of stock for the 30A ... this will be here before all the other gear!! well stoked - thanks Artur
Thought I would add an update - with a years worth of use from this PSU, seeing as its a server power supply I expected the fan to be very noisy, and I still think it would be - if it ever started running! These HP units are very smart and the fan is only used when the supply needs cooling, the up shot of this is that in my year of testing on a Hevo the fan has never kicked in, print runs of 48hrs just dont load the power supply enough. Also because this unit is so overrated the heatbed gets all the power it needs and heats up in a very short time, my original printer an Anet A8 takes three times longer to reach temp, this is going to get the HP upgrade when I get around to it.
Thank you Artur for a great build videos on the XL build!!! I plan on buildings 2 versions 1 small Fabricator mini size and then 1 like you built. Thanks again, these really are an amazing resource for people just starting out. AWESOME WORK!!!
Thanks! I really appreciate your support! And I'm glad I could help. For your mini build, you might want to take a look at my Printrbot to hypercube conversion videos.
Delta power supplies are considered most reliable. You could probably mod the cooling on it a bit to run quieter. Consider that it comes from a server, so the air intake in its natural environment is often going to be too hot to even hold your hand in, but you're running it cool. The HP server power supply that you have is made by... E132068? That would be Lite-On. I'm surprised that it's THIS quiet, noise pollution is rarely a consideration with servers. Not convinced on the utter awesomeness of it, but likely no cause for concern either.
Good point about the first power supply. Might be worth replacing fans with something quieter. For the second power supply - it also has a fan which looks quite beefy as well but it only comes on under load, possibly once temperature inside enclosure raises. I'll see how noisy it gets once I hook up my heatbed in my printer. That will be a serious load. I wish the first power supply also adjusted it's fan speed depending on load/temperature
The heater I'm using in this printer was designed to be powered from 12V. Powering it from 24V would not be a good idea. And no, as far as I know there are no 24V server power supplies. But generally, yes I would advocate 24V for this bed size or larger.

I would recommend 24V for 3D printers bigger than 20x20 cm bed. 24V is also better for the TMC stepper drivers.
EVGA computer power supplies also usually have one big 12V rail.

Not sure if you noticed but green led lights up when you power up the 2nd ps.
Yes, I've noticed that later. Thanks for the tip
Hi sir, thank you for your video. (I understand nothing but no matters).
Are you happy with your Aneng multimeter?
Yes, I actually prefer it over some more expensive meters. Please see my multimeter videos if you're interested in that.
wouldn't you want a 24v power supply with such a large build volume... do they make those power supplies in 24v?

Do you have a link to this power supply?

Artur's Lab thankyou
Artur's Lab I purchased one, currently waiting for it to use in my build, thanks again for the link!
