Question Power supply tester is -5v normal to not show up?

Power supply is "Thermaltake SMART 600W ATX 12V V2.3/EPS 12V 80 Plus Certified Active PFC Power" btw

This power supply?

According to the specs the PSU does not provide -5 volts.

And probably -5 volts is unnecessary.

However, that all said I would be remiss if I did not ask "do you need -5 volts?"

The -5V rail was deleted in the 1.3 version of the ATX spec. It was originally used for the ISA bus.

Yup, the two questions I have are:

• Do you actually need -5V power?
• Is this a cheap enough machine that you really want to use it with this power-supply-shaped object?
