I always wondered what the "HPC" was in the model numbers 🙂. I have yet to see a machine w/ one have any PSU troubles at all, and have messed with quite a few (they are suprisingly common in OEM machines that use standard PSUs), and they are cheap to boot. On the other hand, I do have a deer, and I wouldn't dare use it in anything, as it barely weighs 1 pound!
Edit: just checking High Power's site...the HPC-300-101 (standard Enlight 300w model) is going at $52 from them!!! When I replaced mine (had trouble w/ a Sparkle so gave a customer my PSU and ate the cost instead of doing the whole RMA mess) it was $34 with shipping (Newegg, of course).
Side note: having opened my PSU up (the whole controlled fan speed thing really is there, they just use loud fans 🙂), the switch contacts are there, but for some reason, Enlight doesn't like using a switch. Just an odd tidbit.
