AI Verdict
This non-modular 600W power supply is a basic option strictly for low-power office PCs or budget APU builds, but it's too risky for modern gaming rigs.
While it advertises 600W, the 80 PLUS White efficiency and weak 12V rail performance make it unsuitable for high-end gaming hardware. It works perfectly fine for a 250W office PC or a basic home server, but pushing it past 400W risks instability. Building a rig with a dedicated mid-range GPU requires a more reliable power delivery system.
Step up to an 80 PLUS Bronze or Gold certified unit with a modular cable design for better efficiency and cleaner cable management.

Chance this product isn't for you
Pros
- Includes two 6+2 pin PCIe connectors for entry-level graphics cards
- 120mm cooling fan stays quiet under typical desktop web browsing loads
- Backed by a 5-year manufacturer warranty
- Provides a single +12V rail design for basic component compatibility
Cons
- Non-modular design leaves you stuffing unused cables into your case
- Only carries an 80 PLUS White certification, meaning lower power efficiency
- Voltage on the 12V rail drops significantly under heavy gaming loads according to independent testing
- Exposed multi-colored wires look messy in windowed cases
Dimension Scores
Struggles to maintain 12V voltage under heavy loads and only meets basic 80 PLUS White standards.
The 120mm fan is quiet at idle, but users report it gets loud and sometimes develops a rattle under load.
Internal components are budget-tier, and the unit lacks reliable over-power protection when pushed to its limits.
Non-modular design with stiff, unsleeved multi-colored wires makes routing a nightmare.
Best For
- Basic home office PCs running integrated graphics
- Reviving a 5-to-10-year-old desktop for web browsing
- Ultra-budget builds drawing under 300 watts total
Not Recommended For
- Gaming rigs with modern, power-hungry GPUs like the RTX 4070 or RX 7800 XT
- Compact Mini-ITX cases where hiding extra non-modular cables is impossible
Watch Out For
- Voltage drops under load — independent testers found the 12V rail can dip below 9V when pushed near its 600W limit, causing system crashes.
- Ugly cable aesthetics — the wires are exposed 'ketchup and mustard' colors without full black sleeving, which looks terrible in cases with glass side panels.
- Non-modular clutter — you cannot detach the extra Molex or SATA cables you aren't using, requiring a case with a large PSU shroud to hide the mess.
- Coil whine and static noises — multiple owners report hearing a buzzing or static sound from the unit after a few months of daily use.

What Buyers Say
The massive divide between the 4.6-star Amazon rating and the harsh criticism from PC building communities is the most striking thing about this power supply. Everyday buyers love it for reviving dead office PCs or powering basic APU builds where it barely breaks a sweat. Enthusiasts warn that pushing this unit anywhere near its advertised 600W limit causes severe voltage drops on the 12V rail. The non-modular, multi-colored cables are a frequent pain point for anyone trying to build a clean-looking system. It survives on its accessibility rather than its technical merits.
“Bought this to replace a dead PSU in my old rig, it works fine but trying to hide all these stiff ketchup and mustard cables was a total nightmare.”
Common Praise
- Revives dead office PCs without requiring a massive investment
- 120mm fan is virtually silent when browsing the web or watching videos
- Includes plenty of SATA and Molex connectors for older hard drives
- Fits perfectly into standard ATX cases without clearance issues
Common Complaints
- System crashes and reboots when running demanding games on mid-tier GPUs
- Exposed red and yellow wires ruin the look of windowed PC builds
- Unused cables are stiff and hard to stuff behind the motherboard tray
- Fan develops a clicking or static noise after several months
Ownership Tips
- The fan curve is aggressive, meaning it ramps up audibly as soon as you launch a game.
- Dust buildup inside the unit is noticeable after a few months because the fan intake lacks a dedicated filter.
- Upgrading your graphics card later usually means throwing this PSU away to prevent system crashes.
Frequently Asked Questions
Does this come with the power cord that plugs into the wall?
Yes, it includes a standard AC power cable in the box. You don't need to source one separately.
Will this power an RTX 3060 or 4060?
Technically yes, as it has the required 6+2 pin PCIe connectors. That said, due to voltage drop issues under load, using a higher-tier PSU for modern GPUs is highly recommended to prevent crashes.
Are the cables modular?
No, all cables are permanently attached to the power supply. You will need to find a place to hide any unused SATA or Molex connectors inside your case.
Will this fit in a micro-ATX case?
It uses the standard ATX form factor measuring 150mm x 86mm x 140mm. It fits most micro-ATX cases, but check your specific case's PSU length clearance first.
Does it have an 8-pin connector for the motherboard CPU power?
Yes, it has a 4+4 pin EPS connector. It splits apart if your older motherboard only needs 4 pins, or stays together for modern 8-pin CPU sockets.
Buying Guide
When buying a budget power supply, the wattage on the box rarely tells the whole story. A basic 600W unit like this one is built with lower-quality internal components, meaning it can't safely deliver that full 600W to power-hungry parts like your graphics card. If you are just building a basic computer for emails and YouTube, this will do the job perfectly. If you are installing a dedicated gaming graphics card, do not risk destroying it with a bottom-tier power supply.
80 PLUS Certification
This is like a car's gas mileage. This unit has the basic 'White' rating, meaning it wastes more electricity as heat compared to Gold or Platinum units, which can slightly raise your power bill and case temperatures.
Non-Modular Cables
Imagine a power strip where every single cord is permanently glued in. You have to find a place to hide all the extra cables you aren't using, which clutters up your PC case and blocks airflow.
12V Rail
This is the specific power line that feeds your processor and graphics card. On budget units, this line can lose voltage when you play heavy games, causing your computer to suddenly shut off.
Alternatives
Look for an '80 PLUS Bronze' or 'Gold' certified power supply with a 'Semi-Modular' or 'Fully Modular' cable design to ensure stable gaming performance and a cleaner build.
