AI Verdict
This non-modular 500W power supply delivers basic 80% efficiency for budget APU builds and office PCs, but lacks the internal component quality needed for dedicated gaming rigs.
This unit supplies 500W of continuous power at 40°C, making it perfectly adequate for web browsing and media playback. Pushing it with a modern dedicated GPU exposes its 80 PLUS White efficiency limits and budget internal components. You are trading modularity and high-end protections for a sub-$50 price tag.
If you are installing a dedicated graphics card like an RTX 4060 or RX 7600, step up to an 80 PLUS Bronze or Gold unit rated Tier C or higher.

Pros
- Maintains 80% efficiency under typical loads to meet basic 80 PLUS White certification
- 120mm cooling fan stays nearly silent during web browsing and light office tasks
- Includes a 5-year manufacturer warranty, which is rare for sub-$50 power supplies
- Single +12V rail design simplifies installation without needing to balance power distribution
Cons
- Ranked Tier D on the PSU Cultists list, meaning it is only recommended for iGPU systems
- Non-modular design forces you to hide thick, stiff unused cables inside your case shroud
- Fan noise ramps up significantly and becomes audible when pushing past 300W loads
- Lacks Under Voltage Protection (UVP) and Over Current Protection (OCP) found on higher-end units
Dimension Scores
80 PLUS White certification guarantees only 80% efficiency, wasting more power as heat than Bronze or Gold units.
The 120mm fan stays whisper-quiet during desktop tasks but becomes distinctly audible under gaming loads.
Classified as Tier D on enthusiast lists due to budget capacitors and missing OCP/UVP protections.
The non-modular, stiffly sleeved cables require a spacious case shroud to hide the excess bulk.
Best For
- Home office PCs running integrated graphics like the Ryzen 5600G
- Ultra-budget builds using sub-75W graphics cards like the GTX 1650
- Replacing a dead proprietary power supply in an older pre-built desktop
Not Recommended For
- Gaming rigs with discrete GPUs requiring more than one 8-pin PCIe power cable
- Mini-ITX cases where non-modular cable clutter blocks airflow
Watch Out For
- Tier D classification — PSU tier lists explicitly warn against using this unit with dedicated gaming GPUs due to lower-tier internal components.
- Non-modular cable mess — you will need a case with a dedicated PSU shroud or empty hard drive bays to stuff the unused PCIe and SATA cables.
- Stiff cable sleeves — routing the 24-pin motherboard connector around tight corners requires significant bending force.

What Buyers Say
The most consistent theme across thousands of reviews is that this unit survives for years in basic office PCs but struggles in gaming rigs. Builders frequently complain about the stiff, non-modular cables making clean builds nearly impossible in smaller cases. The 120mm fan earns praise for staying quiet during web browsing, but it ramps up aggressively under load. Enthusiasts strongly advise against pairing it with modern graphics cards due to its Tier D rating and basic 80% efficiency.
“bought this for a cheap ryzen 5600g build and it works fine but trying to shove all these extra stiff cables into my micro atx case made me want to scream.”
Common Praise
- Lasts 5+ years in basic home servers and office PCs
- 120mm fan is virtually silent during web browsing
- Includes all necessary connectors for older motherboards and SATA drives
- Fits perfectly into standard ATX cases with its 140mm length
Common Complaints
- Stiff cable sleeves make routing the 24-pin connector difficult
- Non-modular design leaves a massive bundle of unused cables to hide
- System crashes when paired with power-hungry GPUs like the RX 6700 XT
- Fan noise becomes intrusive when the PC pulls more than 300 watts
Ownership Tips
- Dust builds up quickly on the fan blades because the fan runs continuously rather than having a zero-RPM mode.
- The 80% efficiency rating means the unit exhausts noticeably warmer air than a Gold-rated equivalent.
- The 5-year warranty provides peace of mind, but the RMA shipping cost often equals half the price of the unit.
Frequently Asked Questions
Does this come with the power cord that plugs into the wall?
Yes, it includes a standard 3-prong AC power cable in the box. You do not need to buy one separately.
Are the cables modular?
No, all cables are permanently attached to the unit. You must hide any unused SATA or PCIe cables inside your case.
Will this fit in a micro-ATX case?
It uses the standard ATX form factor with a 140mm length. It fits most micro-ATX cases, but the non-modular cables will make cable management very tight.
Does it have PCIe cables for a graphics card?
It includes two 6+2 pin PCIe connectors on a single daisy-chained cable. This is enough for entry-level GPUs.
Is this power supply loud?
The 120mm fan is quiet under 200W loads but spins up aggressively and becomes noticeable when you push the system harder.
Buying Guide
You are buying a power supply designed for basic computing, not high-end gaming. The 80 PLUS White rating means it wastes more electricity as heat compared to modern standards. Because the cables are permanently attached, you need a case with extra space to hide the clutter. Check your graphics card's power requirements before buying, as this unit lacks the internal protections needed for sudden power spikes.
80 PLUS White Certification
This guarantees the unit converts at least 80% of the wall power into PC power. The other 20% turns into heat, like an old incandescent light bulb.
Non-Modular Cables
Every single cable is permanently wired into the metal box. If you only have one hard drive, you still have to find a place to stuff the other five unused SATA connectors.
Single +12V Rail
Think of this as a single large water pipe supplying your CPU and graphics card, rather than multiple smaller pipes. It prevents you from accidentally overloading one specific cable.
Alternatives
Search for an '80 PLUS Bronze semi-modular power supply' if you want better energy efficiency and the ability to detach unused cables for a cleaner build.
