I've got a 1.6 with good traces that won't power on. If I hold the power button in I can hear the HDD spinning but nothing else happens, no video output, the led's don't light up, nothing.. Before I go about ordering the replacement transistor for the mb, I'd like to test the psu to make sure it's working, and I don't have any other 1.6's around to try it out in. I've been looking around online for 45 mins and can't find anything specific to testing the psu for correct voltage (it's a Delta if that matters, and everything looks flawless on it, no obvious problems.) If anyone can help me out with this, or has another idea of what may be the problem, I'd appreciate it immensely (and yes I have a multimeter handy :P) Cheers, Jim
After cable recall, Xbox's still frying The fix isn't in By Andrew Orlowski, 19 Mar 2005 (TheRegister) 14 million games console owners are still at risk of waking up to find their Xbox has become an ex-box. For when Microsoft issued a safety advisory for Xbox customers last month, it failed to address the underlying problem. After several reports of consoles catching fire, Microsoft urged 14 million console owners to send in their old power leads for a replacement. But hardware experts point out that the power cable was never at root of the problem: it simply made the existing problem worse. The meltdown, and subsequent fire risk was actually caused by wear and tear on the power supply used in early models of the Xbox. The replacement cable featured a trip, which cut down the risk of your house catching fire, but left unfortunate gamers with a fried console. The cord has an interrupter switch that acts like a conventional fuse, tripping power to the unit. Microsoft's decision to limit its liabilities, rather than address the root of the problem, has led to a particularly bizarre situation. Customers who don't need to participate in the program are being shipped an identical cable to the one they've got. Microsoft last month advised console owners to unplug the Xbox from the mains, and claimed the risk is only 1 in 10,000. Ryan, an Xbox modder in Northern California who has disassembled the console, confirms that solder on two prongs holding the Foxlink power supply in place wear out. The problem affects versions 1.0 and 1.1 of the power supply. The design flaw was fixed in subsequent power supplies. I will pop open my case when I can, I know i have a Foxlink PSU
Finally found the time to test the Adapter PCBs i built to use an ATX Psu to power an Xbox. They are plug and play to easily switch between the original psu and an atx-psu.Might be usable for casemods or laptop builds. The adapter is built around the following basic schematic. It properly convert the Standby voltage from 5v to 3,3v and also shifts the power_ok and power_good signals to the correct levels. Also built a small version that can be used to build an extension cord style adapter to save some more space. Just let me know if you have any questions about them
