AI Verdict
This is a barebones, $30 power supply meant strictly for basic office PCs and retro revivals, but the lack of PCIe cables makes it useless for modern gaming.
This unit only makes sense if you are fixing an old office PC or building a retro rig that requires Molex connectors. The absolute lack of PCIe power cables and 80 PLUS certification disqualifies it for any modern gaming build. It delivers 450W, but you can only use that power for motherboards, SATA drives, and integrated graphics.
If you have a dedicated graphics card, upgrade to an 80 PLUS Bronze unit with at least one 6+2 pin PCIe connector.

Pros
- Costs under $30, making it one of the cheapest ATX replacements available
- Compact 5.9 x 5.5 x 3.4 inch footprint fits easily into older prebuilt cases
- 120mm auto-thermally controlled fan stays quiet under basic web-browsing loads
- Includes legacy connectors like 3x Molex and 1x Floppy for retro hardware
Cons
- Zero PCIe power connectors means you cannot plug in a dedicated graphics card
- Cables are unsleeved red and yellow wires that look terrible in windowed cases
- Lacks any 80 PLUS efficiency certification, drawing more power from the wall
- Uses an outdated manual 115/230V voltage switch instead of modern Active PFC
Dimension Scores
Lacks 80 PLUS certification and relies on an outdated manual voltage switch.
The 120mm thermally controlled fan is reasonably quiet under the sub-300W loads this unit can handle.
Features exposed colored wires, thin metal housing, and reports of units failing under sustained loads.
Non-modular design with very short cables makes clean routing nearly impossible in modern cases.
Best For
- Reviving a 10-year-old Dell or HP office tower
- Building a retro Windows XP machine that needs Molex and Floppy power
- Ultra-budget web browsing PCs using integrated graphics
Not Recommended For
- Any gaming PC with a dedicated graphics card
- Modern mid-tower cases where the short cables won't reach the CPU power slot
- Systems running high-end CPUs like Ryzen 7 or Intel Core i7
Watch Out For
- No PCIe cables — you literally cannot connect a modern graphics card unless it runs entirely off motherboard slot power.
- The cables are notoriously short, meaning you will struggle to route the 4+4 pin CPU power behind the motherboard tray in standard ATX cases.
- It lacks an 80 PLUS efficiency rating, so it runs hotter and costs slightly more on your electric bill over time compared to modern units.
- The manual 115/230V switch on the back means if you accidentally flip it to the wrong voltage for your region, you will fry the unit instantly.

What Buyers Say
The most critical detail buyers miss is the complete lack of PCIe power connectors, which instantly ruins the plans of budget gamers trying to power a dedicated GPU. Most positive reviews come from people fixing old office PCs or building retro rigs where the included Molex and Floppy connectors are actually useful. Complaints heavily focus on the short, unsleeved cables that make cable management a nightmare in anything larger than a basic micro-ATX case. While it functions fine for low-wattage web browsing machines, users pushing it near its 450W limit report loud fan noise and occasional system shut-offs.
“Bought this to build a cheap gaming pc for my son but it doesnt even have the plug for the graphics card, totally useless for modern parts but works fine in my old dell.”
Common Praise
- Perfect drop-in replacement for dead power supplies in 10-year-old office PCs
- The 120mm fan is surprisingly quiet when just browsing the web or watching YouTube
- Includes legacy Molex and Floppy connectors for older hard drives and accessories
- Extremely cheap way to test if a motherboard is dead
Common Complaints
- Zero PCIe cables to plug into a graphics card
- The 4+4 CPU cable is too short to route behind the motherboard tray
- Ugly red and yellow cables ruin the look of cases with glass side panels
- Unit runs hot and smells like burning plastic if pushed past 300 watts
Ownership Tips
- Users report the unit can emit a burning plastic smell if pushed near its 450W limit.
- The lack of an 80 PLUS efficiency rating means the metal casing gets noticeably warm to the touch after a few hours of use.
- Several buyers experienced popping sounds and electrical flashes after a few months of daily use.
Frequently Asked Questions
Can this power a gaming PC with an RTX or GTX graphics card?
No. This power supply does not have any PCIe power cables. It can only run graphics cards that draw all their power directly from the motherboard slot, like a GTX 1650.
Does it come with the power cord that plugs into the wall?
Yes, it includes the standard 3-prong AC power cord and four mounting screws in the box.
Will this fit in a micro-ATX case?
Yes, it uses the standard ATX form factor measuring 5.9 x 5.5 x 3.4 inches, which fits in almost all micro-ATX and standard ATX cases.
Are the cables black or colored?
They are unsleeved, exposed red, yellow, and black wires. They are not braided or blacked out.
Is this power supply modular?
No, it is completely non-modular. All the cables are permanently attached, so you will have to tuck the unused Molex and SATA cables into the empty spaces of your case.
Why won't my PC turn on after plugging it in?
Make sure the red voltage switch on the back is set to 115V if you are in North America. Ensure the 24-pin and 4+4 pin CPU cables are fully seated.
Buying Guide
When buying a budget power supply, you need to check the exact cables it comes with, not just the wattage. A 450W rating sounds like enough for a budget gaming PC, but without the specific PCIe cables required by graphics cards, that wattage is useless to you. You also need to measure your case — cheap power supplies have very short cables that won't reach the top of a standard mid-tower case. Look for an '80 PLUS' sticker; units without it draw more electricity and generate more heat.
Non-Modular
All the cables are permanently attached like a squid. You can't unplug the ones you don't need, so you have to stuff the extra wires into the bottom of your PC case.
No PCIe Connectors
PCIe cables are the dedicated power lines for graphics cards. Without them, you can only use integrated graphics or very weak GPUs that pull power straight from the motherboard.
115/230V Switch
Modern power supplies detect your wall voltage automatically. This older design requires you to manually flip a red switch to match your country's voltage, or it will explode.
Alternatives
Look for an 80 PLUS Bronze certified power supply with at least one 6+2 pin PCIe connector and black sleeved cables if you plan to install a graphics card or want a clean-looking build.
