# PSA: Acer Nitro 5 AN515-58 (i7-12650H + RTX 4050) ships with an undersized charger — and it will slowly kill it
**TL;DR:** My Acer Nitro 5 started flickering LEDs and beeping on boot after 2 years. Turned out the stock 230W adapter was degraded. Replaced it with the 280W OEM unit. Problem gone. But here's the thing — it probably shouldn't have been 230W in the first place.

## The symptom
One day my laptop started doing something weird on startup: both LEDs would flicker, a short beep would sound (like the charger got unplugged), and the network card wouldn't initialize. Unplugging the adapter from the wall and plugging it back in usually fixed it — but not always on the first try.
During actual use? Perfectly fine. Games, heavy loads, long sessions — no issues whatsoever. Only on cold boot.
Wiggling the DC jack did nothing. The click-lock connector felt solid. No signs of physical damage.

## The diagnosis
The cold boot behavior was the key clue. When a laptop powers on, it draws a spike of current during POST. If the adapter can't handle that spike — voltage drops, and the system interprets it as "charger disconnected."
Why would a 2-year-old OEM adapter suddenly struggle? Because electrolytic capacitors inside power bricks degrade over time, especially if the unit runs hot regularly. And mine ran hot. A lot.
Which brings us to the real problem.

## Why the stock 230W adapter was always the wrong choice
My colleague has a Nitro 5 too — i5 10th gen, RTX 3050. Same 230W adapter. His runs fine.
Mine has an i7-12650H and RTX 4050. Also 230W.
The i7-12650H has a higher TDP than the i5 10th gen. The RTX 4050 draws more than the 3050. Combined peak consumption on my config can approach — and briefly exceed — 200W under full load. That leaves the 230W adapter with almost no headroom.
Running a power supply near its maximum rated output continuously causes two things:
- It runs hotter
- Its capacitors age faster
Acer's service manual actually lists 280W as an official adapter option for the AN515-58. The part exists. They just didn't ship it with i7/RTX 4050 configurations. Whether that's a cost-cutting decision or an oversight in the product spec sheet — you decide.

## The fix
Replaced the stock Delta ADP-230JB D (230W) with the OEM Chicony A21-280P1A (280W).
Part numbers to look for: **KP.28001.001** or **KP.2800H.001**
Same 19.5V, same 5.5×1.7mm locking connector with the click. Drop-in replacement.
Result:
- Zero boot issues since
- Adapter runs at ~40°C under load vs noticeably hotter before
- Working well within its rated capacity now (~65-70% load instead of 85-90%)

## What you should check
If you have an **AN515-58 with i7-12650H** (or any higher-TDP variant of this laptop):
Check your adapter model — if it's 230W, it's undersized for your config
If you're experiencing intermittent boot issues, LED flickering, or single beep on startup — your adapter is likely degrading
Don't just replace it with another 230W unit. You'll be back in the same situation in 12-18 months
Get the 280W OEM (KP.28001.001) — it's the right spec for this hardware
The 230W might work fine for lighter Nitro 5 configs (i5, RTX 3050). But if you're running the heavier silicon, your charger has been quietly suffering since day one.
