Microsoft Windows 10 (32-bit)

hey all i bought this pc on assumption that hp rep at my local store said i can upgrade the pcu as i want to put low profile graphics card if possible in it or upgrade to 32 gigs of ram like states it can handle and possibly ryzen 5 or 7 what are my options thanks looks like power supply uses 4 pin but im not sure

The spec page for the motherboard indicates the AMD Ryzen 5 3400G, 3.7 GHz Base frequency, up to 4.2 GHz burst frequency, 4 MB cache, Quad core (Picasso) to be the Ryzen 5 choice.


That would also upgrade the graphics as it is part of the CPU.

No Ryzen 7 options.

The spec page for the whole PC


For the memory, it states it can support 2 - 16 GB DDR4 UDIMMs

Believe it or not the PSU in all HP desktop computers is more than adequate. It may seem anemic in comparison to the numbers "recommended" by the graphics card vendors, but rest assured the stock PSU is adequate and good quality.


The reason HP and other manufacturers offer lower wattage PSU is for efficiency. It is more efficient to run a 300W PSU at 90% load than to run a 500W PSU at 55% load. This example is not intended to demonstrate actual usage but is intended to show relationship of efficiency. Efficiency is important when running 25 to 50 to 500 desktops in a work or class environment. 

This is why they are designed as they are and of high quality for trouble free use. 


The rep who sold you your computer did not lie but as many sales people do, did not tell you the whole truth. HP desktops require a proprietary adapter to allow a "generic" PSU to operate within the HP motherboard environment. The design is intentional and not meant to frustrate the customer but to prevent accidents which could damage the entire unit or worse cause a fire. HP is not the only company to do this. 


Memory minimum, maximum, and standards for your specific model are outlined in your HP support documents.

thanks for reply i appreciate it im happy with my pc purchase i just want to make it last as only games i play are older ones and low spec ones such as world of warcraft but ive read  that vega graphics eats ram when i look at spec sheet for my pc it says 16 gig supported and then says 32 gigs supported unbuffered which would be smarter to go with thanks i never knew there was difference in ram lol

The old adage about RAM was you can not have too much is no longer true. 

Non gamer 8GB is plenty

Gamer 16GB is plenty

Artist, Video, Engineer 32GB is plenty

Of course there are extremes in both directions but above is a rule of thumb.


If there are two DIMM slots then 16GB would be max size per slot with a maximum support for 32Gb


Have fun with your new computer!

The HP M01 series can use a full height graphic card.  The PSU is actually a proprietary design, and has two 2x2 power plug (main power and CPU power), and an inline 7 pin stated as Fan power.  All power for DVD or hard drive (3.5 or 2.5) is supplied from the motherboard.  You can not adapt an ATX PSU to work with those units.  It is a fire hazard according to HP.  Others attempted it,, and there was 2 major issues. The adapted PSU refused to start via the power button, and shutdown was not enabled. The OP had to pull the power cord.  That discussion has been flagged.

Your unit has the Erica2 motherboard.  There are no pictures of the Erica or Erica2, or Milton boards.  I was able to get some pictures of the Baker board, so now I can describe it in an article.  Do you think you can do that for the Erica2  ??

Here is my spreadsheet on these issues. Your HP M01 series is there. Little is known about that series. Here is what I have:
