Its a stretch, but the 12v wire juuuuust makes it from the bottom of the case up to the very top of my motherboard where the connection is. Only problem is, its route up there has the wire resting on the XP90, which I assume gets pretty hot while the computer is running. Is it ok on there? Is it possible to get an extension cable for it so I can route it better?

I doubt that the xp-90 would get hot enough to damage the wire. When I touch my xp-90 it never seems very hot.

It's not the temperature I'm worried about - insulation is meant to take heat in excess of 100C I believe. Rather, I'd be worried about mechanical strain and obstruction to airflow (if any).

Conformance standards for the type of wiring and insulation that power supplies use demands a melting point of greater than 175F degrees. Long before you melt the insulation on your ATX12V line you'll have a much more painful problem, a toasted CPU. Actually, a good PSU would never let it happen, because it would throttle or shut down in any over-current or over-voltage condition that would generate that much heat. Even if the fan burned out on your XP90, the CPU might give up the ghost but it won't get to 175F before it does and shuts everything off.

Short answer, you're fine. I expect to see PSU makers noticing all of the new cases that mount the PSU in the bottom, and extending the cable length for the main power and ATX connectors.

Great, glad to hear I'm not gonna burn my house down :shock:

Lenny, about airflow and mechanical strain, they're not really an issue. The wire doesn't run across the top of the xp90 (like, along the top of the fan or something), so airflow is fine. It runs along the side of the cooler, and its not pressed up hard against it or anything, it just rests against it, there just isn't quite enough slack to route it any other way.
