my dell dimension 5150 was correctly powered down and when i re-powered up it went to blinking amber on the power switch. took the side panel off and saw the green light on the mother board but nothing happening, i.e psu not kicking into life
any suggestions, i think possibly psu has maybe had a bit of a power surge ? and blown something in itself
if so where the heck can i get another, dell web site is not very helpfull
the machine is a dell 5150 and about 16 mobths old
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.
I replaced a PSU on a Dell Dimension 5150 yesterday which was having the same issue. I installed a standard 600W PSU, screw fixings are in the standard place and the main board is a standard ATX form factor. The fit is slightly off due to the fact dell have put in a sliding bracket just to be difficult and charge you twice as much.
