AI Verdict
A 500W fully modular Mini ITX/Flex ATX power supply for compact builds where budget and small size are the top priorities.
This 500W fully modular Flex ATX PSU is a strong contender if you absolutely need its specific compact dimensions and modularity for a tight small form factor build. However, its 40mm fan is a known source of noise, and there are user reports of questionable build quality, making it a compromise for budget-conscious builders. It's a fit if you understand and accept these trade-offs.
If noise is a concern, look for Flex ATX PSUs with larger fans (e.g., 80mm) or those specifically marketed as low-noise, often at a higher price point.

Pros
- Fully modular design allows for using only necessary cables, reducing clutter in small cases.
- Compact dimensions of 160mm x 73.66mm x 35.5mm fit Mini ITX/Flex ATX form factor cases.
- Provides 500W maximum power, suitable for many small form factor systems.
- Includes 2x 6+2 PCIE connectors, supporting modern graphics cards.
- Features Overvoltage, Overload, Overcurrent, Heating, and Short Circuit Protections.
- Full Range Active PFC (90-264V) contributes to stable power delivery.
Cons
- The 40mm double ball bearing fan generates significant noise, especially under load.
- Some units arrive with rattling components inside, indicating potential manufacturing inconsistencies.
- Users have reported a distinct "cheap electronic smell" upon unboxing.
- Lacks a physical power switch, meaning it's always 'on' when plugged in and connected to a PC.
- Cable lengths, while suitable for most compact builds, may be too short for ultra-tight cases.
Dimension Scores
The 500W maximum power with Full Range Active PFC and specified outputs (+12V@33A) is standard for its class.
The 40mm double ball bearing fan is consistently reported by users as loud, particularly under load.
Reports of rattling components and a 'cheap electronic smell' upon arrival suggest inconsistent manufacturing quality, despite listed protections.
The fully modular design is a significant advantage for cable management in small form factor cases, allowing for cleaner builds.
Best For
- Small form factor PC builds where space is extremely limited
- Point-of-sale (POS) systems requiring compact power solutions
- Entry-level compact gaming rigs with lower power draw GPUs
- Small server builds that prioritize a tiny footprint
Not Recommended For
- High-performance gaming PCs with power-hungry components
- Noise-sensitive environments where quiet operation is critical
- Users prioritizing long-term reliability and premium component quality
Watch Out For
- Rattling sounds from inside the unit have been reported immediately after unboxing.
- The 40mm fan can be "crazy loud" even with systems pulling only 140W, making it unsuitable for quiet builds.
- Some users experienced a "cheap electronic smell" similar to low-quality imported electronics upon opening the package.
- The power supply does not have an on/off switch, so it powers on immediately when connected to a PC and wall outlet.
- One user reported multiple units failing, with one burning a hole in a carpet after three months of use, though this was for a different Apevia model, it highlights brand concerns.

What Buyers Say
The biggest thing users talk about is the noise from that tiny 40mm fan; it's not quiet, especially when your system is actually doing something. Some folks even got units with loose bits rattling around inside right out of the box, and a few mentioned a strong 'cheap electronics' smell. While it's fully modular and fits into super small cases, there's a real trade-off on the noise and perceived quality front. It seems to work for many in lower-power setups, but don't expect a premium experience or silent operation.
“Look, it's cheap and it's modular for my tiny case, but man, that fan sounds like a jet engine taking off when I'm just browsing, and I swear I heard something rattling when I shook the box.”
Common Praise
- Fully modular cable design simplifies installation and reduces clutter in tight spaces.
- Compact Mini ITX/Flex ATX form factor fits into very small cases.
- 500W power output is sufficient for many small form factor builds.
- Includes dual 6+2 PCIE connectors for graphics card compatibility.
- Affordable price point compared to other modular Flex ATX PSUs.
Common Complaints
- The 40mm fan is very loud, even under moderate system loads.
- Units sometimes arrive with internal components rattling loose.
- A noticeable "cheap electronic smell" is present upon initial unboxing.
- Concerns about long-term reliability and potential for failure have been raised by users.
- Lack of a physical power switch is an inconvenience for some users.
Ownership Tips
- The 40mm fan's noise becomes very apparent after a few days of use, especially if the system draws more than minimal power.
- The absence of a power switch means you have to unplug the system or use a switched power strip to fully cut power.
- Some users report it working fine for months in low-power systems, suggesting reliability might be load-dependent.
- The 'cheap electronic smell' tends to dissipate after a few days of operation.
- Cable lengths, while modular, can still be a challenge in extremely compact or custom-designed cases.

Buying Guide
When you're looking at power supplies for tiny PCs, the form factor is everything. Mini ITX/Flex ATX PSUs like this one are designed to squeeze into cases where standard ATX or SFX units just won't fit. You're often trading off noise levels and sometimes component quality for that small size. Also, modularity is a huge deal in these cramped builds because it lets you ditch unused cables, making cable management way easier and improving airflow.

Alternatives
If this doesn't quite fit, look for Flex ATX PSUs with a larger fan size (e.g., 80mm) for quieter operation, or a higher 80 Plus efficiency rating for potentially better internal components and reliability.
