AI Verdict
A 500W SFX power supply with 3 SATA and one 6/8pin PCIe, sized for compact builds, but user reports suggest reliability and noise issues.
This 500W SFX power supply is a situational fit for extremely budget-constrained small form factor builds due to its compact dimensions and low price. However, its non-modular cables, reported noise levels from the 80mm fan, and numerous user complaints about early failures make it a risky choice for anything beyond the most basic, non-critical systems.
If you need better reliability, quieter operation, or easier cable management, look for SFX power supplies with an 80 Plus Bronze or Gold certification and modular cabling.

Pros
- Compact 125mm x 100mm x 63.5mm dimensions fit well in small form factor cases.
- 500 watts of output power supports mid-range system components.
- Includes a 6/8pin PCIe connector for a single graphics card.
- Offers 3 SATA connectors for storage devices.
- Split 8pin CPU (4+4) and PCIe (6+2) connectors enhance motherboard and GPU compatibility.
Cons
- Non-modular cabling makes cable management difficult in tight enclosures.
- The 80mm cooling fan can generate significant noise under load.
- Multiple user reports indicate early failure, some within 5 months of use.
- Lacks an 80 Plus efficiency certification, suggesting lower power efficiency.
- No power switch on the unit, potentially causing sparks when plugging in.
Dimension Scores
The unit lacks an 80 Plus certification, and some users consider its effective 12V rail output closer to 400W, not 500W.
The 80mm fan is frequently cited by users as noisy, with one user describing it as 'the world's loudest power supply'.
Numerous user reports detail early failures, rattling internal components, and a 'cheap electronic smell,' indicating questionable manufacturing quality.
The non-modular cables are difficult to route and manage in the confined spaces of SFX cases, leading to clutter.
Best For
- Budget mini-ITX or Micro ATX builds with a single, mid-range GPU.
- Replacing a failing SFX power supply in an older, less demanding compact system.
- Small form factor office PCs or HTPCs where space is the primary constraint.
Not Recommended For
- High-performance gaming PCs with power-hungry GPUs or multiple storage drives.
- Quiet PC builds where fan noise is a critical concern.
- Systems requiring high reliability or long-term stability for critical tasks.
Watch Out For
- The 80mm fan can be 'the world's loudest power supply' under load, according to one user.
- Some units fail within 5 months, even in systems drawing only 250W-280W.
- Non-modular cables create a 'tangled mess' in compact cases, making clean builds challenging.
- One user reported receiving a unit with 'two broken pieces of plastic' rattling inside.
- The unit lacks a power switch, leading to sparks when plugged into an outlet.

What Buyers Say
The most striking finding from user feedback is the consistent concern about this power supply's reliability and noise, with multiple reports of units failing within months, even under moderate loads. Many users also struggle with the non-modular cables, which create significant clutter in the small form factor cases this unit is designed for. Despite its compact size and low price, the trade-offs in build quality and acoustic performance are frequently highlighted.
“Dude, this thing died on me after like 4 months, and the fan sounds like a jet engine when I'm just browsing. Don't cheap out, seriously.”
Common Praise
- Compact 125mm x 100mm x 63.5mm dimensions fit well in small form factor PC builds.
- 500 watts of power is sufficient for mid-range systems with moderate power needs.
- Includes a 6/8pin PCIe connector for single GPU support.
- The split 8pin CPU (4+4) and PCIe (6+2) connectors offer broad compatibility.
- Low purchase price makes it accessible for extremely tight budgets.
Common Complaints
- The 80mm cooling fan can become very loud under load.
- Units have failed prematurely, some within 5 months of use.
- Non-modular cables are difficult to route and manage in cramped cases.
- Some users received units with internal rattling or a 'cheap electronic smell'.
- Lack of a power switch on the unit can cause sparks when plugging it in.
Ownership Tips
- The non-modular cables are stiff and make closing the side panel of a mini-ITX case a real struggle.
- The fan noise is noticeable even when the system isn't under heavy load, making it unsuitable for a quiet desk setup.
- The lack of an 80 Plus rating means it runs hotter than expected, warming up the entire case.
- You'll need to be extra careful plugging it in since there's no power switch to prevent sparks.
- The limited 3 SATA connectors forced me to use an adapter for my extra SSD.
Frequently Asked Questions
Is this power supply modular?
No, this power supply has fixed, non-modular cables, which can make cable management challenging in small cases.
Does this power supply have an 80 Plus efficiency rating?
No, an 80 Plus certification is not listed for this model, suggesting it may not meet those efficiency standards.
What size is the fan in this power supply?
The power supply features an 80mm automatically thermal sensing fan.
Can this power supply handle a high-end graphics card?
It includes one 6/8pin PCIe connector, which is suitable for a single mid-range GPU, but not for high-end cards that require more power connectors.
Does this unit have a power on/off switch?
No, some users have reported that this power supply does not include a physical power switch.
Buying Guide
When you're looking at power supplies, especially for small computers, you need to think beyond just the wattage. You're trying to fit a lot of power into a tiny box, so cable management, noise, and how long it actually lasts are huge. Don't just grab the cheapest one; a failing power supply can take other components with it.
Wattage
This is how much power the unit can deliver. For SFX units, 500W is enough for a single mid-range graphics card and CPU, but it's not for high-end gaming. Think of it like the engine size in a small car – enough for daily driving, but not for racing.
Form Factor (SFX)
This refers to the physical size of the power supply. SFX units are much smaller than standard ATX power supplies, designed specifically for compact cases. It's like choosing a compact car for city driving versus a full-size SUV.
Modular vs. Non-Modular
Modular power supplies let you detach unused cables, making your build much cleaner and improving airflow. Non-modular, like this one, means all cables are permanently attached, which can be a nightmare in small cases. It's the difference between custom-cut cables for your setup or a tangled mess of spaghetti.
80 Plus Certification
This rating (Bronze, Gold, Platinum, Titanium) indicates how efficiently the power supply converts wall power to usable PC power, reducing waste heat and electricity bills. No rating means it's likely less efficient, like a car with poor gas mileage.
Alternatives
If this unit doesn't fit your needs, search for SFX power supplies with 80 Plus Gold certification, fully modular cabling, and a larger fan (120mm or 140mm) for quieter operation.
