Are all power supplies the same size?

Jedicake

Or at least the vast majority? The crazy 1500w ones bigger?

Yes and no. The wattage it can deliver determines the size to an extent, but they will differ even at the same wattage rating.

1500w is much bigger than 500w

 

1500w is slightly bigger than other 1500w

No. There are different PSU form factors (ATX, SFX), modular power supplies tend to be slightly bigger than non-modular power supplies, and 1500W PSUs tend to be bigger as smaller wattages.

Most ATX PSUs are the same size though.

There are small form factor (SFX) power supplies measuring 125x100x65mm compared to the normal ATX 150x140x86mm (I think..). Silverstone is currently the leader of SFX PSUs.

 

There are also higher Wattage PSUs that are longer than lower Wattage units.

All ATX PSU's have the same height and width, but have different lengths
