All this may be considered fluff to some of you who are just waiting to see the power outputs the EG451P-VE is capable of. This powersupply is capable of handling some pretty serious currents!

A peak inside the Enermax illustrates what goes into this little bundle of joy. Should you ever overload it, there is a fuse to protect the unit from any permanent damage.

The EG451P-VE is designed to incorporate several life saving features in the event anyone ever tried to hook up 34 RAID drives, and half-a-dozen 72watt TEC's. :) If the load on the power supply exceeds 130%-160% of the maximum output current it will shut down. Why the PSU chooses such a broad range is not really clear. Additionally if any of the DC outputs short, the PSU will shut down to hopefully save your but from being on the end of a large jolt. My guess is that the fuse inside of the PSU just blows, as opposed to some little bit of intelligent circuitry. But I'm not about to test the theory.

Damn this thing is powerful!

While we were hooking up our powersupply to the floppy drive we accidentally missed a pin, so the connector ended up being one down. If you ever had any doubts about the power the EG451P-VE is capable of putting out, then you would have been converted upon witnessing the fire and smoke instantly shooting out from the back of my A:\ drive. Power was on for about a second before I turned everything off rather quickly! The drive survived, but remains scarred.

What I am going to be testing is to see what kind of differences a 431W powersupply can bring to the performance of your computer if you happen to be cooling by Thermoelectric-based devices, like the MC1000, or MC2000. Can you get away with just using a 250watt-300watt powersupply? Or do you need something a bit more powerful? I'll let the results speak for themselves in case you have any doubts.
