My current Slot Athlon + Voodoo 5 is running with a 20 year old, no-name power supply. I would hate for it to destroy my precious hardware.
So I bought 2 Enermax ATX power supplies. They have decent 3.3V and 5V rails for older machines. But most important, decent failsafe mechanisms to minimize chances of damage from failing PSU.
Besides having laid around a warehouse for 13 years, they are brand new (I broke the seal myself to inspect the inside). The weird thing is that the label with the specifications is missing. The factory packaging, all test stickers and seals are present, also case badges and screws. My best guess is that they are old distributer stock and that different labels are applied by the distributer for different regions or retail/OEM. There is a chance that they are rejects, but why apply all quality stickers and include case badges in the package then. Anyway, I will test them thoroughly before installing one in my most valued machine.
I had to use the internet archive to determine the exact type. Also the date stamp inside the PSU housing and the fuse type helped in the determination. It turns out that they are EG425AX-VE(W) ATX2.2 (there is a slight possibility that it is the EG495, but it was sold as EG425). It is a 420Watt PSU, rated for 30A on 3.3V and 30A on 5.0V together at max 160W. This should be the equivalent of a decent quality 300W-350W oldschool ATX power supply. Enough for most retro systems.
