Maynuo M8811 power supply no-reserve auction
« on: September 11, 2013, 01:04:55 AM »

The story of this PSU is that a customer asked me to order one of these PSU's for him but unfortunately this one arrived (from China) with some physical damage. I could have returned it but I would still have to lose a lot of shipping fees on this heavy beast. I went ahead and ordered another one for the customer and he received that one safely a while ago. I thought about keeping this damaged one for myself but I don't really need another PSU on my bench at the moment so I'm now auctioning it off. The starting price is $125. Shipping (air parcel through Hong Kong Post) is already included in the auction, you won't have to pay any more than your bid (except potential import duty/tax which I have no control over).

As far as I can tell (by testing it with the Maynuo M9712 DC load I have), the unit is functioning correctly. Please see the numerous pictures I have attached on the auction page for the physical damage.  To me it seems like the unit somehow took a knock during its journey from the factory to my place and the very heavy transformer caused the base plate to bend.

These PSU's are usually selling for over $400 plus shipping so I'm fairly hopeful that it will at least get one bid and get sold! Happy bidding!

I have been using my new M8811 power supply quite a bit over the last couple of weeks.  I like it so far.
(I'm the customer referred to in the original post.)

Frankie did great getting the unit, finding the damage, reordering and then inspecting and testing the replacement unit before sending it on to me.

Here's an action shot of the M8811 driving a PIC32, set to 3.3000 volts, it's readback showing 3.2999 and the Agilent 34410A showing 3.2992 (some loss in the leads).

(edit) attached smaller image.
