Honor 9 Lite review
For the past week when I start up my main computer in the morning it takes between 20-40 presses of the power button before it will start,
I have checked the wires from the power button to the motherboard and they are OK, I have also checked the power button and that is OK.
Once I have started it up I can shut it down and it will start first time then, but if I leave it for a couple of hours the same problem occurs.
Any suggestions as to what could cause this would and how to cure it would be appreciated.
Agree PSU is on its way out.
If renewing a PSU check:
1. The physical size of your PSU, some are hard to replace due to being a non standard size.
2. The amount of power need from the PSU don't skimp
1. Physical Dimensions
Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:
# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
# Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
# MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
# Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.
Use the data above to determine if a particular power supply would fit your case.
The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.

Guide to changing PSU
My PSU is an Antec 480 watt modular unit and is about 18 months old, as I do not have another to try your theory out, it is going top be expensive to replace if that is not the problem.
Is there any way to check out the PSU before I buy another one.
Fruit Bat /\0/\ thanks for all those links, they may be useful, but as I build my own computers may I just point you in the direction of this link for PSU calculation as it is more up to date and includes all the new processors.
