pc4 8GB RAM and PC 3 8 GB?

Here are a few great options for 8GB RAM that should suit your needs: The CMK16GX4M2B3200C16 Vengeance DDR4 RAM kit is only R1005 and will provide fast 3200MHz speeds for your PC4 motherboard. For PC3, the Dominator Platinum CMD8GX3M2A2800C12 kit at R3280 runs at an even faster 2800MHz. Both of these kits include two sticks of 8GB each for dual channel support. Let me know if you need any other details on these performance memory options!

Here are a few good options for a Dell all-in-one power supply: The HP 1000W Flex Slot Titanium Hot Plug Power Supply Kit for R8219 would be a high-quality choice suitable for powerful Dell all-in-ones. As a flexible titanium supply, it will ensure efficient power delivery and low heat output. For smaller, more basic Dell all-in-ones, the Laptop Charger Ac Adapter Power Supply For Acer 65W 5.5X1.7MM for R279 or Laptop Charger Ac Adapter Power Supply For Acer 90W 5.5 1.7MM for R279 would work well. They are compact and inexpensive while providing adequate power for less demanding systems. My apologies but it seems the PriceCheck search results did not contain any power supplies specifically listed as being for Dell all-in-ones. The options I mentioned above should be compatible but always best to confirm specifications match your Dell system's requirements. Please let me know if you need any other recommendations.
