content: Image from Agilent webThere will be an auction locally here for this power suply with these following conditions :- Model N5745A DC System Power Supply, 30V, 25A, 750W with details -> (Agilent web)- New old stock, never used with the original box, printed cal certificate and standard accessories.- Even though in new condition, Agilent standard 3 years warranty is considered expired, since its a surplus unit from a finished big project years ago.- Allowed to test briefly after winning at the auction site only, once its out of the auction site, no more warranty what so ever.- Bidding price starts at $100.Questions :- Comments or opinions from experienced user/owner on this particular N5700 type or better this particular model please ?- Any potential issues or anything else that I should aware of ?- After watching one of Agilent demo videoHERE, just watch for the video background noise, is that loud & noisy fan sound from this PS is normal ? Will it be very annoying (yes, its subjective I know) if it will be used on a quite personal workbench at home ?- If you're going to bid, with above conditions, whats your max bid ?TIA

content: Those Blade type appliances have very small fans and tend to be noisy. They are designed to be rack mounted and the connections are in the back. It is a beautiful power supply but inconvenient to use as a bench power supply. I have the Agilent 6624A and 6627A and rarely use them for that reason.

content: Thanks, btw, does the fan throttle down if on light/no load ? From the video it seems like its on full speed all the time ?Thinking of possibilities of dismantling the top cover, put it into bigger enclosure like 2 or 3 U height close rack, and replace the fan with much less noise bigger fan ? Also I need to route that two giant terminals to the front anyway.Apart from the noise, any other potential or existing minor quirks ? Is it fiddly to use ?
