Quick Specs Summary
Correction (September 2026): this page previously described a “Dell Inspiron 14 Plus 5430” with two DDR5-5200 SO-DIMM slots and user-replaceable memory, and recommended SO-DIMM kits to go with it. There is no Inspiron 14 Plus 5430 — Dell’s Plus models are the 7000 series — and the machine it described is the Inspiron 14 Plus 7430, whose memory is soldered to the board and cannot be upgraded at all. The RAM recommendations have been removed and the charger corrected. If you bought SO-DIMMs on the strength of the old page, they will not fit this laptop.
| Spec | Details |
|---|---|
| Display | 14″ 16:10 (1920×1200 or 2240×1400) |
| CPU | Intel Core i5-1340P / i7-1360P (13th Gen) |
| RAM Type | LPDDR5 / LPDDR5x 4800MHz — soldered to the system board |
| RAM Slots | None — there are no SO-DIMM sockets |
| Max RAM | 32GB, fixed at purchase (16GB or 32GB configurations) |
| Storage | 1 × M.2 2230 or 2280 PCIe NVMe (user-replaceable) |
| Charger | 90W or 130W barrel (4.5 × 2.9mm, 19.5V), or 100W USB-C |
Can You Upgrade the Dell Inspiron 14 Plus 7430?
Partly. The storage can be replaced; the memory cannot. Dell’s owner’s manual for this model states the memory is integrated on the system board, and there are no memory sockets inside the chassis to populate. Whatever you specified at purchase is what the machine will have for its life.
That makes the buying decision the important one. If you are choosing a unit now, take 32GB — the upgrade path that exists on most laptops does not exist here.
RAM: Soldered, Not Upgradeable
Do not buy SO-DIMM memory for this laptop. The Dell Inspiron 14 Plus 7430 uses LPDDR5 or LPDDR5x at 4800MHz, soldered in two integrated modules, in 16GB (2×8GB) or 32GB (2×16GB) configurations. There is no socket to fit a module into. Any listing offering a “RAM upgrade kit” for this model is selling you something that cannot be installed.
Because both channels are populated by design, the machine always runs dual-channel, so there is no single-stick penalty to fix either. If 16GB is proving tight, the realistic options are closing background applications, increasing the page file, or replacing the laptop — not a memory purchase.
SSD and Storage Compatibility
This is where the machine is upgradeable. There is one M.2 slot that accepts either a 2230 or a 2280 drive, running PCIe NVMe. The 2280 option is the useful one — longer drives are cheaper per terabyte and far more widely stocked than 2230 drives.
Check which length is fitted before you order. If yours came with a short 2230 drive, you will need to move the mounting standoff to the 2280 position, which is a single screw. A second M.2 2230 slot exists but is occupied by the Wi-Fi and Bluetooth card — it is not a storage slot.

Charger Compatibility
Dell offers three adapters for the Dell Inspiron 14 Plus 7430, and which one your laptop shipped with depends on its configuration:
- 90W barrel — 19.5V, 4.5mm outer / 2.9mm inner connector
- 130W barrel — 19.5V, same 4.5 × 2.9mm connector
- 100W USB-C — 20V/5A, with 15V, 9V and 5V fallbacks
So USB-C charging is genuinely supported on this model, which is not true of every Dell. If you are buying a replacement, match what is printed on your original: a 90W barrel unit will run a 90W machine but will undercharge a 130W configuration under load, and the two barrel sizes Dell uses across its range are not interchangeable.

Upgradeability Summary
| Component | Rating | Notes |
|---|---|---|
| RAM | None | Soldered LPDDR5/LPDDR5x; no sockets; specify 32GB at purchase |
| SSD | Good | One M.2 slot taking 2230 or 2280 NVMe |
| Charger | Good | Barrel or USB-C supported; 100W USB-C option is a real one |
| Overall | Limited | Storage only — buy the memory you need up front |
How to Upgrade the SSD
Power off, unplug, and remove the bottom cover screws. Lift the cover from the hinge side. The M.2 drive sits under a small thermal pad or shield; remove the single retaining screw, lift the drive out at about 30 degrees, and seat the replacement the same way. If you are changing from a 2230 drive to a 2280, move the standoff to the far mounting hole first. Refit the screw finger-tight.
Back up before you start, and read Dell’s service manual for your exact service tag — it will confirm which drive length your unit shipped with.
Frequently Asked Questions
Can I upgrade the RAM in the Dell Inspiron 14 Plus 7430?
No. Dell’s own documentation states the memory is integrated on the system board and cannot be upgraded. There are no SO-DIMM slots.
How much RAM can it have?
16GB or 32GB of LPDDR5/LPDDR5x at 4800MHz, decided when the laptop is built.
What SSD fits it?
One M.2 NVMe drive, either 2230 or 2280 — the slot supports both lengths. Check which is fitted before ordering.
Can I charge it over USB-C?
Yes. Dell offers a 100W USB-C adapter for this model alongside 90W and 130W barrel adapters. Match the rating on your original.
Is there a Dell Inspiron 14 Plus 5430?
No. Dell’s “Plus” laptops are 7000-series, so the Plus model of this generation is the 7430. There is a plain Inspiron 14 5430, but it is a different machine with a lower 16GB memory ceiling — also soldered.
