Five Power Supplies Compared

EconolineCrush writes "Tech Report has done up a comparison of five high-end power supplies that looks at actual voltage levels and AC ripple content. The article also takes a look at environmental factors like noise levels and each power supply's impact on system temperatures. Think power supplies with like wattages are created equal? Think again."

I hear it'll show up if you eat a lot of beans...

Actually, in some cars like Porsches, gas is not just gas. Higher performance cars are going to run at a higher compression, which allows for more power. Higher octane gasoline will prevent premature detonation when running higher compression.

Someone else in this thread mentioned older cars pinging, which is a sign of premature detonation. Newer cars will not ping with low octane gas since their fuel management system will adjust for the crappy gas. As a result you will get no pinging, but the car will lose some of its power.

ObTopic: Anyone have specs on how the PS put in Macs are? How would they compare to these five PC power supplies?

Assuming...

1) Sufficient octane rating (and remember that higher octane ONLY EVER HELPS YOU if you advance your timing, or you engine has computer-controlled advance)

2) Sufficient quality

Then hell yeah! I'm continually amazed by people who don't understand that higher octane doesn't make them go faster. I guess the take-home lesson is that people are morons.

Anecdote time. About 15 years ago (ack!), a friend of mine spent a summer sampling gas for the government, here in Alberta (Canada, folks). What she found was that it was very typical for a Shell station to get Esso gas delivered in a Husky truck. The tank drivers would fill up with whoever had gas nearby, and sell it as demands required, and the gas companies had worked out some formal agreements along those lines.

She also found that there was absolutely no practical difference between any refinerys' gas at a given octane rating, with the ONE exception of a certain company's leaded gas, which had an unacceptable level of particulates in it. (Leaded gas was still available to farmers only back then. Don't know about now)

So find the octane you need, put it in, and run it.

I've heard from several mechanics that the mid-grade gas is much better for your car, and that you don't get much benefit when stepping up to the high stuff. Interestingly, some newer cars (my Mom's new minivan, for instance), are made for the cheap stuff. It even says so in the owner's manual!

Oh please. Offtopic? This whole thread from the parent I replied to on down is offtopic. Get a clue mods. Moderate everything or nothing.
