Seasonic M12II 500 review

[burebista]

by SKYMTL or Antec EA500 refined.

With the M12II 500W, Seasonic seems to have manufactured the perfect power supply for consumers looking for modularity without breaking the bank.

The only other area we found needed some improvement was with the +12V rail outputs. While a combination of 17A and 18A should be more than enough for anyone, we would have preferred to have seen either two 18A rails or a single, larger rail.

Thanks SKYMTL for another nice review.

Are these really multi 12V? Did you check the traces?

[jonnyGURU]

I'm pretty sure it's actually a single +12V rail.

Loading a heavily overclocked and water cooled HD2900XT shut the PSU down so I assume that it bumped into the OCP.....

And plus, I will not make assumptions based on tests I cannot back up with facts.

[Super Nade]

Still, it is worth checking the terminations to double confirm your test results.

I would be surprised if Seasonic all the sudden went back to separate OCP circuits.

[jonnyGURU]

A quick and easy way to check (skillful folks only, please).

Use a DMM, set to measure DC current. Most cheap units support up to 20A. Better units will support up to 40A. Put one probe in +12V and the other in ground. The Amps will click up and up and up. Eventually the PSU should shut down. If the PSU doesn't have OCP, you'll see the higher numbers on the DMM. Of course, the DMM should shut down if it hits it's limit, or blow it's fuse.

Whelp....unfortunately, I don't have the time to hook it back up and it is buried under a pile of other units. I will check again in about a week...
