Marginal OEM Power Supply
Last summer I bought a box from a very big OEM at a good price.
The box would not boot on delivery because the RAM had been installed incorrectly, so it's clear that, if the box was tested, it was tested before the RAM was installed, and now I'm wondering at what stage of assembly the boxes are supposedly tested (not at all after assembly?). I increased the memory by 50%, reinstalled the incorrectly installed memory, and added a second HDD, and the machine did boot. I haven't used the machine much, and, in particular, I haven't used the video much, but this summer I started encountering video problems while trying to upgrade Fedora. Since I had an extra video card available, I tried changing video card. My replacement video card drew too much power and the machine would not even boot. The easy conclusion was that the power supply was either malfunctioning or marginal to begin with. The computer store is a fair drive, so I bought both a replacement power supply and a very low end video card. I don't like replacing power supplies, so I tried the video card. Works like magic. I'll replace the power supply if I get around to it. I mostly run the box remotely and I don't need fancy video. As far as warranties are concerned, I can't imagine what circumstances would make a warranty repair worth my time, so I don't worry about it. Maybe when you pay for installed upgrades, you pay for an upgraded power supply. Since the memory was added to this box with no further testing, it's easy to imagine that boxes might be shipped with upgrades such that the power supply is often marginal or inadequate. Anybody have any insight? Robert. |
