HP ProDesk 480 G1 Microtower vs. HP ProDesk 490 G1 Microtower

Differences between HP ProDesk 480 G1 Microtower and HP ProDesk 490 G1 Microtower

Both computers, the HP ProDesk 480 G1 Microtower and the HP ProDesk 490 G1 Microtower, were released during the same year - 2013.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

Processor

The two models have the same generation of Intel processors. We think that the 4 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The HP ProDesk 490 G1 Microtower has 4 RAM slots while the HP ProDesk 480 G1 Microtower has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.

None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 1600. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 490 G1 Microtower as it has the ability to run 32 GB of RAM. The HP ProDesk 480 G1 Microtower can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP ProDesk 490 G1 Microtower has 10 USB ports. The HP ProDesk 480 G1 Microtower is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.

Nowadays, almost every new computer comes equipped with a DisplayPort. However, none of the devices being compared here has one. Don't worry though, DisplayPort adapters are very cheap and you can get virtually any combination of conversion types.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.

SATA slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 480 G1 Microtower, nor the HP ProDesk 490 G1 Microtower has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!

Power Supply

Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 300 Watts. However be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU. This will potentially allow you to upgrade to a more powerful GPU for example.
