The year 2007 probably will be viewed as the year that people really got their eye up on the whole environmental issue, regardless if you believe in our impending doom or not. No one can deny that wasting energy is not exactly a good thing and if you, like me, live in a country where electricity comes at quite a high price you would want to keep the power usage down. Unfortunately it still seems that the price to pay for being at the technological bloody edge is that you consume electricity at the same rate as a small third-world nation.
When AMD released their HD2900XT's it was noted that you not only had to use 2 PCI-E connectors on it but even had to use a new 8-pin PCI-E connector if you wanted to overclock it. Combine one or two of these (or for that matter a couple of GeForce 8800 Ultra) with a Quad-Core CPU and a bunch of hard drives and your local power company will be able to afford yet another luxurious Christmas party this year.
Of course the PSU-makers have followed suit and are now offering even more powerful PSU's just to satisfy our need for power. Today I am testing the High Power 1000W PSU from Sirtec with the goal to find out whether it is any good and also if this kind of power is actually needed even on a high-end system.
