Well... I didn't expect that hot temps would affect this unit so significantly. I don't think that any other Seasonic AT based unit had similar problems.

XFX Core 850W @[H] had similar problems, maybe there IS something to it.

But given that most cases nowadays isolate PSU from case's airflow, it shouldn't be too bad.

For the record, NZXT tells me these are rated for 40 degrees at full power.

PS. TX850M goes for the same price @TD (it's less modular though)

TX850 v2 is MORE expensive now, which makes little sense.

One other thing - now that I've been in there and have re-soldered everything in the secondary, the unit is now back to the ripple suppression it had in the cold tests.

The results are not really a surprise as much as they are a bit of a let-down. As it seems a platform error, not really something that NZXT, XFX, or Corsair could control.

Though, it's definitely not a "huge" problem. As Raf said, almost any case isolates the PSU from the heated air of the CPU or other components in the system so the unit shouldn't warm up that much. More so, the given results are still a rather extreme condition.

None the less, it is something that should be adressed by a revision. So that this kind of issue doesn't actually occur in normal use.

I've got the 750W sitting right here, looks pretty similar at least as far as I can tell without desoldering things. Main difference is the second primary cap is about half the capacitance of the first cap and half as tall. Semiconductor parts are probably different too, but it's hard to tell on this unit without taking it apart, and the few parts where I could get a look at the printing it was worn to near-illegibility.

Oh. Like they say - you learn something new every day I was not expecting such a flop from Seasonic, though I do agree it's not that big deal.

IMO the 850W AT's are just pushing this design too far for comfort.
