The YEYIAN YPA-YU84F0B-5601U is a prebuilt gaming desktop pairing a Ryzen 5 8400F with a GeForce RTX 5060 8GB GDDR7. This article works through the published specs and the retail listing to explain where the machine shines and where you have to compromise.

Overview

The YEYIAN YPA-YU84F0B-5601U is a mid-high gaming PC built around an AMD Ryzen 5 8400F (6 cores / 12 threads, up to 4.7GHz) and an NVIDIA GeForce RTX 5060 8GB GDDR7.

It ships with 16GB of DDR5-6000 memory, a 1TB NVMe SSD, a 650W 80+ Gold power supply and Windows 11 Home pre-installed, so it is usable the moment you attach a display and keyboard. Four RGB case fans handle airflow, aiming at stable behaviour during long sessions.

The short verdict: this configuration is happiest at high-refresh 1080p and at 1440p with high settings, using upscaling where needed. If your target is native 4K, VRAM-hungry flagship titles, or professional rendering, a higher tier will serve you better.

Think of it as a machine for someone who wants a complete gaming PC without picking parts.

Amazon.co.jp reviews stood at 17 ratings and 4.0 out of 5 stars (80% positive) when captured on 22 May 2026.

With only 17 data points, treat that as "no widely reported disasters" rather than proof of reliability.

Performance in Practice

The Ryzen 5 8400F has 6 cores and 12 threads, and as the F suffix indicates, it has no integrated graphics. The graphics card is therefore mandatory: pull it out or have it fail and you get no picture at all.

Six cores remain perfectly usable for gaming, but if you plan to stream and encode in the background while playing, higher-core CPUs pull ahead in exactly that scenario.

The RTX 5060 8GB GDDR7 comfortably drives most titles at high settings at 1080p. 1440p is well within reach with some setting adjustment and upscaling, but this is where the 8GB VRAM ceiling matters.

Recent games with high-resolution texture packs or ray tracing enabled can push VRAM usage sharply, and 8GB cards can show late-loading textures or brief stutter even while the frame rate looks fine. Getting comfortable with one notch lower texture quality is the realistic long-term approach here.

16GB of DDR5-6000 is enough for games alone. Keep dozens of browser tabs, Discord and streaming software open alongside, though, and 16GB fills faster than you expect.

DDR5 runs in dual channel pairs, so upgrading by swapping in a matched 32GB kit — or adding a matched pair — causes fewer problems than adding a single stick.

Compatibility Guide

The published compatibility data lists an ATX tower form factor, DDR5 memory support and a recommended 650W supply. Key points before you buy:

The most commonly missed detail is that Wi-Fi and Bluetooth are not built in — the manufacturer's compatibility note says so explicitly. If the PC will live away from your router, plan for an Ethernet run or a USB Wi-Fi adapter.

The same applies to wireless keyboards, mice and headsets that expect Bluetooth. "It arrived and could not get online" starts right here, so order the adapter alongside the machine.

The 650W 80+ Gold unit leaves real headroom for an RTX 5060-class build, and a future GPU upgrade probably would not force a PSU swap. That said, measure card length, in-case clearance and check the auxiliary power connector type (some recent cards expect a 12V-2x6 adapter cable) before any swap.

ATX tower or not, front fan interference does happen.

Connect displays to the graphics card outputs. Motherboard video ports are unusable with a graphics-less 8400F — this trips up almost every first-time builder.

Product Info

The configuration is model YPA-YU84F0B-5601U with an AMD Ryzen 5 8400F (6C/12T, up to 4.7GHz), 16GB DDR5-6000, a 1TB NVMe SSD, a 650W 80+ Gold PSU and Windows 11 Home.

The box contains mainly the power cable and documentation; keyboard, mouse and monitor are separate purchases. Warranty follows manufacturer terms, generally one year on parts — confirm the exact coverage with your seller.

The price was ￥352,247 on Amazon.co.jp as captured on 2 June 2026.

Prices move frequently and sales can cut them substantially, so always check the current figure on the product page before ordering. The overseas marketplace entry (an eBay search) showed no fixed price at capture time, and terms vary per listing.

Bluntly, that captured price is not cheap for a Ryzen 5 8400F plus RTX 5060 build. It is well worth quoting an equivalent configuration from a domestic system builder before committing.

What you are paying for is the convenience of a finished machine, a single warranty contact and the finished look including RGB fans. During a meaningful sale, the value equation changes considerably.

Competitive Comparison

If you are cross-shopping at this price, narrow the decision to two axes: VRAM capacity and CPU core count. Prioritise VRAM and an RTX 5070 12GB class build gives breathing room exactly where 8GB struggles.

Prioritise CPU headroom and an 8-core Ryzen 7 build handles streaming and video editing alongside gaming far more gracefully.

The YEYIAN's position becomes genuinely strong when three things are true: you only play at 1080p–1440p, you want it working out of the box, and you have no interest in debugging part compatibility or driver setup. With those constraints, the premium for a higher tier is hard to feel.

Best Use Cases

Good fits:

• First-time gaming PC buyers — a complete build with no part-selection or assembly risk.
• High-refresh 1080p players — competitive titles like Fortnite and Apex Legends are this build's sweet spot.
• 1440p players willing to tune settings — with upscaling, demanding titles remain very playable.
• Hobbyist creators — 16GB DDR5 and the RTX 5060's encode/CUDA capability cover short-form editing and learning projects.
• Buyers who care about looks — a finished RGB build without doing the work yourself.

Poor fits: native 4K play, permanent streaming plus local recording, professional rendering, or running large local models. Those users should start at 12GB+ VRAM and 8+ CPU cores and will spend less overall by doing so.

Before You Buy

1. 8GB VRAM is the first wall you hit. The RTX 5060's GDDR7 bandwidth is fast, but capacity is 8GB.

Stack high-resolution texture packs and ray tracing and you run out of VRAM before you run out of frame rate, which shows up as late texture loads and stutter. If "everything on maximum" is your goal, accept this compromise up front.

2. No wireless. Wi-Fi and Bluetooth are absent. Depending on placement, sort out an adapter or Ethernet cable before the PC arrives.

3. No peripherals included. Keyboard, mouse and monitor are extra.

A high-refresh monitor in particular is what unlocks this build, so budget beyond the sticker price.

4. 16GB is an obvious future upgrade. Fine for games alone; less so once streaming software and browsers run alongside.

Replace as a matched kit to preserve dual-channel operation.

5. The captured price is on the high side. ￥352,247 as of 2 June 2026 is an ambitious number for this configuration.

Compare it directly against equivalent domestic builder quotes, and consider waiting for a sale.

6. Do not take the listing metadata at face value. Retail product-information fields — manufacturer, model number, included accessories — are sometimes registered incorrectly and do not always match the actual item.

This article covers model YPA-YU84F0B-5601U; before ordering, confirm from the product images and title that you are looking at the Ryzen 5 8400F / RTX 5060 configuration rather than relying on the spec table alone.

7. The review sample is small. Seventeen ratings is not enough to judge failure rates or long-term durability.

Test thoroughly on arrival — load-test games, check temperatures, verify storage detection — while you are still inside the return window.

FAQ

Q. Can it game at 4K? A.

Some titles, yes, but comfort is not realistic. You would be lowering settings and leaning on upscaling to reach 60fps.

Choose a higher tier if 4K is the goal.

Q. Does it have Wi-Fi?
A. Not as shipped. Add a USB Wi-Fi adapter or use wired Ethernet. Bluetooth is likewise absent.

Q. Can I add memory or storage? A.

As a DDR5 ATX tower build, upgrades are generally possible, but the number of free slots depends on the board — verify on the product page. Memory upgrades must be DDR5.

Q. Nothing appears on the motherboard HDMI port. A.

The Ryzen 5 8400F carries the F suffix and has no integrated graphics. Always connect displays to the graphics card.

Q. Can I upgrade the GPU on a 650W supply? A.

Capacity-wise there is room for a tier up. Check card length, thickness, connector type and in-case clearance first.

Q. Are a keyboard and mouse included?
A. No. Expect mainly the power cable and documentation. A monitor is also required separately.
