The total output was thus 64 kilowatts and had required an up-rated power supply to be laid to the ground.
2.
The power connectors on the back of these systems incorporate a " keying " system that will prevent plugging a ( newer ) lower-rated power supply into an older system ( which needs more power ).
3.
Ultimately though, subject to the provision of appropriately rated power supplies, air cored systems can operate with much greater magnetic field strengths than " iron cored " systems, so that, ultimately, much higher accelerations and forces should be possible.
4.
A hard disk could not be installed into the 5150's system unit without changing to a higher-rated power supply ( although later drives with lower power consumption have been known to work with the standard 63.5 Watt unit ).

Samples of PSE approved power supplies and PSE certificates can be found here, PSE rated power supplies are characterized by classes and ratings ranges rather than specific model numbers : http : / / en . globtek . com / news / pse-approved-power-supply-ac-adapters-meet-japan-denan-regulations-for-import-and-sale-in-japan

Why I consider this odd / interesting, is that I assume the rest of the PC must vary in how much power it consumes, therefore for a given rated power supply, I would have assumed that given a particular power supply, the amount of spare power left over for the graphics board would vary from one pc to another, but ? ? talk ) 15 : 58, 18 March 2013 ( UTC)
