I manage a couple of somewhat out of date HP Servers. They are so old I am worried about the power supplies. The power supplies are still working OK. It will take me 2 to 4 months to replace these servers with new Servers. I found replacement power supplies online but the vendor shows two models: standard efficiency and high efficiency. I don't know what I have now unless I pull one to look at it, but I want to avoid pulling one. Here are the vendor product links: https://www.harddrivesdirect.com/product_info.php?products_id=455417 https://www.harddrivesdirect.com/product_info.php?products_id=45740 The Server Make/Model Numbers are listed in the compatible list for both of the Power Supplies, above. I want to buy a pair. Do they have to be matching pairs? Do you think that they will both work for my servers? Thanks in Advance.
