CPU (Processor) : 

- Intel® Xeon® E5-2680 v4

• 14 cores / 28 threads — strong multi-core performance for pro tasks like rendering, simulation, CAD, video editing, virtual machines, etc.

• Up to ~3.20 GHz with Turbo Boost — excellent for threaded workloads.

Memory (RAM) : 

• Installed RAM (example typical config): 32 GB DDR4 ECC

• Type: ECC Registered DDR4 (error-correcting for stability)

• Slots: 8 DIMM slots total

• Max Supported: Up to 128 GB ECC registered

• Speed: Up to 2400 MT/s with E5-2600 v4 processors

ECC RAM helps catch memory errors automatically — useful in professional and critical workloads.

Storage : 

The Z440 supports a flexible mix of storage types:

Typical Installed Storage Example (varies by configuration):

• SSD: 240 GB (PCIe / SATA SSD — fast boot and app load)

• HDD: 1 TB SATA HDD (large media/data storage)

General Supported Storage Options:

• SATA SSDs and HDDs (standard 2.5″ / 3.5″)

• SAS HDD/SSDs (enterprise drives)

• HP Z Turbo Drive / Z Turbo Drive G2 NVMe SSD (PCIe SSD)

• Up to 4 drives total (with adapters)

You can mix SSD + HDD for speed + storage capacity.

Power Supply (PSU) :

• Standard PSU: ~700 W unit (typical in Z440 models)

• Efficiency and exact rating depend on configuration but most systems used a HP-branded 700 W PSU.

 A 700+W PSU is usually enough for the Xeon CPU and mid-range GPUs; bigger cards might push you toward a stronger PSU.
