| 240874 | 2004-06-01 22:08:00 | It could be worth checking with a meter kiki, unless of course you really do want the justification to upgrade.:D The difference between boot and no boot on my faulty PSU was around 0.25 volts on the 5 volt standby rail. It was down to 3.46 volts but would still start OK at that level. It varied intermittently as well, and if it dropped to 3.2 volts it wouldn't start up. Fitting an external cap raised the output to 3.8 volts which is still 1.2v below the spec but enough to make it start every time. Incidentally, it had been making an annoyingly loud sizzling noise from the PSU when switched off, which my son complained about because the box is less than a metre from the head of his bed. Fitting the cap stopped the noise which was an added bonus. Cheers Billy 8-{) |
