Dell PowerEdge R720 Parts Guide — Every Component You Need in 2026
Complete parts guide for the Dell PowerEdge R720 — motherboards, power supplies, RAID controllers, backplanes, rails, drives, fans, and cables. Compatible part numbers with pricing.
Why the Dell PowerEdge R720 is Still the King of Refurbished Servers
The Dell PowerEdge R720 is the most popular refurbished 2U rack server in the world. Released in 2012 as a 12th generation PowerEdge, it remains the go-to choice for homelabbers, MSPs, small businesses, and even production data centers in 2026. Why? Because it hits the sweet spot of performance, expandability, and price that no other used server can match.
With dual Intel Xeon E5-2600 v2 CPUs (up to 24 cores total), 768GB max RAM across 24 DIMM slots, and up to 16x 2.5" or 8x 3.5" drive bays, the R720 handles VMware ESXi, Proxmox, TrueNAS, Windows Server, and Docker workloads without breaking a sweat. And with used R720s selling for $150-400 on the secondary market, the main ongoing cost is replacement parts.
That is where Pro Disk Network comes in. We stock 513 Dell PowerEdge R720 parts — every component from motherboards to bezels — at 50-70% below Dell's pricing.

R720 Motherboard / System Board
The R720 motherboard is the most critical and expensive component. A failed system board means a dead server unless you have a replacement.
Compatible Part Numbers
| Dell Part # | Description | Price Range |
|---|---|---|
| 0X6H47 | R720/R720xd System Board (v1 - E5-2600) | $80-150 |
| 0C4Y3R | R720/R720xd System Board (v2 - E5-2600 v2) | $100-180 |
| 0JP31P | R720/R720xd System Board (v2) | $100-180 |
| 0M1GCR | R720 System Board | $80-150 |
| 0VWT90 | R720xd System Board | $100-180 |
Pro tip: The v1 boards (E5-2600 only) and v2 boards (E5-2600 + v2) look identical but have different BIOS. Always match the board revision to your CPU generation. v2 boards are backward-compatible with v1 CPUs but not vice versa.

R720 Power Supplies
The R720 uses hot-swap redundant PSUs — pull out the dead one, slide in the replacement, zero downtime. Two wattage options:
Compatible Part Numbers
| Dell Part # | Wattage | Price Range |
|---|---|---|
| D495E-S0 | 495W | $18 |
| D750E-S1 | 750W | $25 |
| E750E-S0 | 750W | $28 |
| F750E-S0 | 750W | $25-35 |
| F9F51 | 750W | $30-40 |
Which wattage? 495W is sufficient for a single CPU + 4 drives. 750W is recommended for dual CPU, full memory, and 8+ drives. Always install two identical PSUs for redundancy.

R720 RAID Controllers (PERC)
The PERC (PowerEdge RAID Controller) manages your drive array. The R720 supports:
Compatible Controllers
| Model | Cache | Interface | Best For | Price Range |
|---|---|---|---|---|
| PERC H310 Mini | None | 6Gb SAS | JBOD/passthrough (TrueNAS, ZFS) | $15-25 |
| PERC H710 Mini | 512MB | 6Gb SAS | RAID 0/1/5/6 (general use) | $30-50 |
| PERC H710P Mini | 1GB | 6Gb SAS | RAID 5/6 with large arrays | $40-70 |
| PERC H310 Adapter | None | 6Gb SAS | PCIe card version | $15-30 |
For homelab/TrueNAS users: Flash the H310 to IT mode for direct drive passthrough. This gives ZFS direct access to each drive without RAID abstraction.
For production RAID: The H710P with 1GB cache and battery backup is the best choice for RAID 5/6 arrays.
