    Help Needed Diagnosing Startup Issue after Power Disconnect

    PSUs for electronics can continue outputting power after AC power is lost. For example, essential when a UPS spends significant time with neither AC power nor battery power as that UPS switches from one to another. This 'time' decreases as the load increases. That slowly decreasing power is...

    Again, this is why/how we learn - by making mistakes. Or as Tommy Smothers once said, "I'll never make that mistake again."

    Help Needed Diagnosing Startup Issue after Power Disconnect

    If that wire measures zero volts, then power could not turn on. However if that wire is actually the adjacent (other side) red wire, then it measures 5 volts only when powered on. By swapping your pin # 4 with 16 and pin # 9 with 21, then everything makes sense. +5VSB pin 9 is outputting...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    Confusion is created by using pin #s rather than wire colors. Apparently you have confused pin 21 (red wire) with pin 9 (purple wire). Measuring pin 9 at 3.74 is a defect. Original instructions called for measuring that purple wire when power was not on. If I remember, you did not do that...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    Just remember what has already been determined. If the PSU is a problem, then two problems exist: power supply and potentially harmful leakage into 3.3 volts. If reason for failure is only that leakage, then a PSU supply intermittently misbehaves because of that leakage. Either way, that...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    One who did this stuff for 40 years and who designed power supplies says a meter can identify ripple voltage and other problems. To know why (and what numbers are relevant) requires additional knowledge. Also known - big capacitors discharge quickly in seconds. This function, required in...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    You have clearly seen what the problem is. Capacitors that take too long to charge inside a power supply do not affect the Power Good signal. Since that signal stays and is suppose to stay in not Power Good until those capacitors charge. This is normal. Larger capacitors that take even...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    Those numbers are not taken as instructions requested. For example, a purple wire (+5VSB) is measured only with power off and power cord is connected. Green wire is measured before, monitored when, and measured after the power button is pressed. Gray wire is measured by the same before...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    Restore every connection as when the computer worked. AC power cord connected to a receptacle. Computer not on. Set a digital meter to 20 VDC. Attach its black probe to the chassis (bare metal; not paint). Locate a purple wire (pin 9) from PSU to where it attaches to the motherboard. Use a...

    Help Needed Diagnosing Startup Issue after Power Disconnect

    So much to address / correct. This will start with your power cycling issues. Normal is for a defective power system to boot and operate a computer. Often this defect becomes more obvious in a warm room (ie 100 degree F - a normal temperature for any properly functioning computer)...

    PSU vs UPS – Understanding and Matching Capacities

    First, as you have seen, if a computer might consumer as much as 300 watts, then computer assemblers are told to buy a 600 watt supply. Because these people typically do not know parameters necessary to select a supply. So they are told to buy double what is required - to keep help lines...

    Surge Protector vs Lightning Strike

    No. A number is one of many reasons why. Low impedance (ie 'less than 10 feet'). How many feet from appliance to that safety ground in a receptacle. That is safety ground; not earth ground. How many more feet inside walls? How many sharp bends? How many splices? Etc. All can result in...

    Surge Protector vs Lightning Strike

    Your telco's $multi-million switching computer connects to all other buildings. Therefore it will suffer about 100 surges with each storm. So they disconnect phone service before each storm? Of course not. Protection even from direct lightning strikes has been routinely done for well over...

    Computer randomly restarts while playing.

    First, those voltage numbers are so wrong that the computer could not even execute to report those numbers. Ataxie told you how to get replies from the fewer who know this stuff. For example, the surge protector obviously is unrelated to your symptoms. Second, a foundation of every computer...
