I have a AP-MPS3ATX35, what is the replacement for this or do you have one to sell?

On a quick search the dimension of that model is 5.86" x 3.3" x 4" so this model (ATX300-PA) is not a compatible replacement. This power supply has the atx sized facing on the fan and plug end but the depth on the inside is shorter than a regular atx power supply so its an odd ball to find a replacement but a quick filter on newegg site with micro-atx power supplies shows BESTEC ATX-1956 and Enhance ATX-1125BTA-R300 as a viable replacements. A quick google search also gave me result to same model to buy if you don't want something different. Good luck

does fsp atx-300pa replace fsp atx-250pa(1)?

The only diffrence is the wattage output. The atx300 is 300w and the atx250 is 250w. I prefer to use at least a 300w power supply with basic machines.

Does anyone have the dimensions on this unit? I must be getting old, I didn't see them in the description or specs.

Product Type ATX12V & EPS12V Power Supply Dimensions 5.90" Height x 5.50" Width x 3.40" Depth all power supplies are standard sized just like motherboards are i did check to see if the specs are correct i own one of these

What are the dimension of this?

As listed in the specifications tab, '5.75”(W) x 3.25”(H) x 5.5”(D)'.
