Results

Well the test was a bit easier than I would have thought. I could not get the computer to even start using a 250W power supply and the MC1000. With the Enermax 431W powerhouse cpu temperatures hovered around 7.3 C using the MC1000 and a lapped Celeron 366.

In conclusion if you want to install one of the most powerful power supples out there, the Enermax EG451P-VE is an excellent solution. It's price is very reasonable, it is one of the quietest powersupplies we've seen anywhere, and it is packed full of features that will extend its life span for many years down the road. For the overclocker with multiple thermoelectric devices the high current of the Enermax may help you run your TEC's cooler if they had been starved for electricity before. All in all this is one damn good powersupply!

All that said, we give the Enermax 431watt PowerSupply the PCstats Editor's Choice Award! Congratulations, it's well earned.
