A Dell power supply label can show three or four different codes, and customers often send us the wrong one. This guide explains which number matters, what the prefixes mean, and how to use them to order the right replacement PSU.
The Codes on a Typical Dell PSU Label
| Code type | Example | What it is | Use it to order? |
|---|---|---|---|
| Dell Part Number (DPN) | GRTNK or 0GRTNK | Dell’s own 5-character part number; often printed with a leading 0 | Yes, best choice |
| Full label (PPID) | CN-0GRTNK-xxxxx-xxx-xxxx-A00 | Country + DPN + supplier/date/serial + revision | Yes. Just read the middle part (0GRTNK) |
| Manufacturer model | L495E-S0, D495E-S0, DPS-495AB | The OEM factory’s model number for the same Dell part | Useful as a cross-check |
| Wattage | 495W | Output rating | Never on its own |
Reading the Dell Part Number
- The DPN is 5 alphanumeric characters, e.g. GRTNK, F9F51, VPR1M, 787J3.
- A leading 0 is commonly added: 0GRTNK = GRTNK. Both refer to the same part.
- On the full CN-0XXXXX-… label, “CN” is the country of manufacture (China). Other codes include MY (Malaysia), TW, MX and so on. The country code doesn’t affect compatibility.
- The last characters (e.g. A00, A01) are the revision. Revisions of the same DPN are normally interchangeable.
What DPS-, L- and D- Mean
Dell doesn’t build most of its PSUs itself. The manufacturer model tells you which factory made it:
- DPS-xxx / D-xxx: made by Delta Electronics
- L-xxx / PS-xxxx: made by Lite-On
- Other OEMs you may see include AcBel, Chicony and HiPro
One Dell part number can have several OEM versions. For example, the 495W GRTNK exists in both Lite-On (L495E-S0) and Delta (D495E-S0) versions, and both work in the same server. That’s why the Dell part number is the safer reference than the OEM model.
Multiple Dell Part Numbers for One PSU
Dell often issues several part numbers for functionally equivalent PSUs. This is why some of our listings show more than one number:
- Dell 750W PSU F9F51 / 6W2PW / YNCW3: PowerEdge R620 / R720 / T620
- Dell 570W PSU VPR1M / RXCPH: PowerEdge R610 / R710
- Dell 500W PSU 60FPK / H318J / MHD8J: PowerEdge R410
- Dell 240W PSU 0DN02 / JVW1K / DK87P: OptiPlex 3050 / 5050 / 7050 MT
If your label shows a number that isn’t in our listing title, send it to us anyway. It may be a cross-referenced equivalent.
Same Wattage, Different PSU
Here’s why wattage alone is risky. Both of these are Dell 250W server PSUs, but they are not interchangeable:
- Dell 250W C627N / V38RM: PowerEdge R210 / R220 (non hot-swap)
- Dell 250W P3G94: PowerEdge R240 (proprietary connector)
Desktop PSUs work the same way. OptiPlex SFF units from different generations use different connectors (for example, 24-pin vs 6-pin vs 4-pin motherboard power):
- Dell 240W J50TW: OptiPlex 390 / 790 / 990 / 3010 / 7010 / 9010 SFF (24+4 pin)
- Dell 200W K92TW: OptiPlex 3070 / 5070 / 7070 / 3080 SFF (6-pin)
- Dell 260W 7JGJF: OptiPlex 3090 / 5090 / 7090 SFF
Quick Checklist Before You Order
- Dell part number from the label (e.g. 0GRTNK)
- Server or PC model and form factor (MT / SFF / Micro / rack)
- A clear photo of the label and the connector: how to photograph an IT part
Frequently Asked Questions
Is 0GRTNK the same as GRTNK?
Yes. The leading zero is just padding on the label.
Can I use a Delta version to replace a Lite-On version?
Yes, if both carry the same Dell part number (or an official Dell equivalent).
Does revision A00 vs A02 matter?
Usually not. Revisions under the same DPN are designed to be interchangeable.
The label is worn out. What now?
Send us your server’s Service Tag or model and a photo of the PSU. We can usually identify it. See where to find a server PSU part number.
