• Manufacturers of computer power supply units (PSUs)
• Sites offering reviews and comparisons of PSUs.
• Sites offering technical information, industry news relating to PSUs
• Resellers/retailers* of PSUs which deliver worldwide.

Resellers that do not specialise mainly in PSUs, e.g. sell a wider range of computer products, should submit to the relevant alpha category of http://dmoz.org/Computers/Hardware/Retailers/

Companies which manufacture power supply units for other equipment/purposes than computers should be submitted to Business/Electronics_and_Electrical/Power_Supplies/ (or a relevant subcat.)
