Hello I need a power supply for a Dell poweredge R640, but I mostly find power supplies for other models, such as the R620. Can somebody confirm if I need a specific PSU for the R640, or there are other PSUs compatible as long as the minimum wattage requirement for the R640 is met? (compatible regarding connections) Are the R620 power supplies compatible with the R640? Is there a way to know if a power supply is compatible by reading its model number? Or is there a document where all the compatible power supplies for the R640 are listed? Thanks
