PSU 12v amperage - Page 3

post #21 of 30
40a on the 12v rail means it will deliver 480w on the 12v, which is what most components in your machine utilize.

I also have over a dozen other articles, follow the link in my signature.
I really didn't understand much of that. Amps must matter or they wouldn't have them. And if amps don't matter why do you have a 1200W PSU with 8 30A 12V rails? Could you not settle for a quality 800W or 1000W PSU?

Also amps do matter in the sense that if you have to many you can flip your breaker. Yours might do that..

My system would run on a quality 650W, and I have several decent 750Ws laying around that are adequate. I use the HCP-1200 because it's an engineering sample so I'm obliged to hang onto it indefinitely, so I'd rather use it than have it take up shelf space.

So, ok, let's try a different way of explaining it. Amperes (not amps, as that has too many other connotations)... Amperes = power. The higher the amperage, the higher the wattage, and the higher the wattage the higher the amperage. They are linked. Quality power supplies of similar wattage will have similar amperage ratings on the +12V rail. Most quality 500-550W power supplies have 40-45A on the +12V rail. Most quality 750W power supplies have 60-62A on the +12V rail. Etc. The only time looking at the amperage is more important than looking at the wattage is when a manufacturer is trying to cheat and inflate the wattage number to make the PSU look better. And I'll tell you when that's being done.

Is that easier to understand?

I would have to say that makes more sense. Maybe you should add that to the post I read.

So, based on what you said/know. What do you think of the antec PSU that was recommended earlier?

It and the SeaSonic are about equivalent on performance, quality, and power. Difference is that the SeaSonic has fewer hardwired cables (more modular), but the Antec is a little cheaper after that discount code. The SeaSonic may have shorter cables; I'm not sure.

The antec seems to have what look like longer cables. I think i'll go with it.

Not as good a performer, it's a lower end unit. Still solid though.
