Phaedrus PSU Q&A - August - Page 6

post #51 of 56
Two questions.
First, I realize it is september 1st, so will you be starting another one of these threads for this month?

Second, I have done a lot of reading in the last few months on different psu's and their respective manufacturers. I have found that some oems are very good(seasonic, delta, CWT etc.) and I know of others best avoided. I was wondering what the top 5 or 10 power supply oem companies are and which retail brands they supply. I feel this would be a very helpful tool in picking a quality psu.

Thanks!

Thread Starter 
I will be starting a new one, but I'm going out of town (have to wake up at 4 tomorrow... fun) so it might not be until next week.

Well good luck on your trip!

I guess try to answer the oem question when you get back.

What happens when you go over the specified amps for a single rail on a multi rail unit?

not sure, but if the other rails aren't being fully utilized, will there be some kind of compensation?

EDIT: am i correct with this: 12v, 30 amps = 360w?

Well, I mean, if you go far enough over the rated amperage for one of the rails, OCP trips and your PSU shuts off. The other rails can't compensate for the overloaded rail, each OCP rail is assigned a certain set of connectors to power.

And yes, your math is correct, but that math is really only good for calculating the maximum rated wattage on a single rail. The PSU label should contain information on the maximum combined rating for all available 12V rails.

OCP, usually isn't set to what's shown on the rail though.
Most of the time, it's 5-10A higher than what's shown on the rail.

To my knowledge, Antec is the only company that actively publishes OCP set points on their PSU's
