I've had a look in the ATX12v 2.x spec too and can't find it. 😕

See under "5.1 Temperature" (pg. 37 in your link). So it says "recommended" & not a must like I said in my previous post. Not like I'm gonna remember every minute detail of that spec sheet & I did afterall say "if memory serves".

Since you're posting links, I'll provide a couple links of my own...


Notice "environmental" & what's listed under "temperature"

PC P&C (0°-50° C)
OCZ (0 to 50° C)

If you wanna ask ppl from OCZ (John & Ryder) what the 50° C applies to in that OCZ link, go here. Cause whatever I say, I doubt I'd be able to convince you otherwise.

Hardly conclusive evidence. Environmental temperature means the temperature the PSU can operate at. In other words the PSU should be able to operate in the range of 0 - 50°C. The spec says absolutely nothing about the PSU having to perform at it's rated wattage output at up to 50°C like you have said.

And that's the point I'm getting at, most PSUs can run up to 50°C no trouble, they are designed to. But most PSUs are rated at 25°C to inflate their wattage rating. So when they hit 40°C (typical power supply temp) then they will drop their wattage load.

Now so far you have not shown me any evidence to prove that an OCZ power supply will do a continuous 520W or 600W at typical PSU temperatures. So who knows how much they actually output when it gets hot inside the PSU?

We get a subtle clue from the OCZ spec sheet that they rated their MTBF @ 140,000hrs but at 25°C. Well it's highly doubtful that the PSU will always be at 25°C. You've got the PSU generating heat, the CPU, video card, everything else generating heat. So that MTBF failure rating is also misleading.

Anyway I have asked the OCZ guy the same question and we'll hope for a definitive answer. All I'm asking for is confirmation, but so far I'm getting none.

1) Remember that OCZ link stated "Operating temperature" between 0-50° C. Now if I'm wrong, so is SilentPCReview (#3 on the right). I'm pretty confident you'll get the same answer from them [OCZ] as well.

2) If that's so then why would Enermax rate their old PSUs operating temp at 25° C, while their newer PSUs are rated @ a much higher operating temp?

3) Happy?

4) MTBF = Mean Time Before Failure, it's an estimation of the longevity of a PSU @ those temps, not the capability of a PSU @ so & so temps.

5) Give 'em time. It's only 7:41 AM in the eastern seaboard, let alone the rest of the U.S.
