Can I replace a PSU with model PCA019 for an HP Compaq Pro 4300 sff with a PSU model PC9055 for HP Compaq 6200 sff? Both have similar DC output.

Hey Lala, It looks like as long as it physically fits it should be ok from a power stand point. The 6200 PSU is a bit more efficient, but that is never a problem haha. I hope this helps a bit.
