Dual amperage rating "+12V @ 34A/38A" and other things

messiahnet · 04-01-2005, 08:59 PM

I was checking out some PSUs from PC P&C's website. When looking up specs, I took a look at the amps off the 12V rail and it read "+12V @ 34A/38A". Now, the 34A/38A part is the part I don't get. Is it 34 amps or is it 38? Also, I noticed a rating that read "-12V @ 2A". Now I'm really confused. I read your PSU 101, Praetor (if you're viewing this), and I'm really trying to understand all of this. NICE tutorial by the way. It's helped me out TONS!!! I don't know what amperage to accept as the true rating. Should I also add that 2A on the -12V to the 34A (or 38A). Confusing.

The 38A is the peak or max amperage (mentioned in PSU 101). The -12V only goes to powering the mobo (Praetor might be able to elaborate on that), so no, don't add that to the base 12V rail.

(really you should only be concerned with the +tive rails)
