Fantastic linear power supply from HDPLEX. I am the original owner and it is new/unused. I paid $868. I only took it out of the box to take pictures. Thought I would need to upgrade my LPS, but decided to keep my less powerful HDPLEX200 and sell this HDPLEX500 as it supplies more power than I currently need.

These are out of stock from the US distributor and have been for quite some time. Get this one while you still can. I don't foresee global supply of these increasing too soon.

HDPLEX 500W ATX Linear Power Supply Package Content:
1 x HDPLEX 500W Linear Power Supply
1 x ATX Bridge Modular Input Board with Internal and External ATX Cable set
Two XLR - 5.5/2.5mm and Two XLR-5.5/2.1mm Cable (3ft/1m)

The unit weighs 30 pounds so I am going to keep this sale limited to North America.
