AI Verdict
This 650W 80+ Gold non-modular power supply is a cheap, reliable engine for budget 1080p gaming builds where hiding extra cables in a PSU shroud isn't a problem.
The 650W capacity and 80+ Gold efficiency easily handle mid-range components like a Ryzen 5600X and RTX 3060. The non-modular design means you need a case with a PSU shroud to hide the unused cables, making it a poor choice for ultra-compact or glass-heavy builds.
If you are building in a tight case, upgrade to a fully modular PSU like the Corsair RM650 to only plug in the cables you actually need.

Pros
- Hits 80+ Gold efficiency levels for under $60, drawing less wall power than Bronze alternatives.
- 120mm hydraulic bearing fan stays virtually silent during desktop use and light gaming.
- Includes four 6+2 pin PCIe connectors, enough to power older power-hungry cards or mid-range RTX 30-series.
- Compact 140mm depth fits easily into smaller ATX and Micro-ATX cases.
Cons
- Non-modular design forces you to hide thick, unused SATA and Molex cables inside your case.
- Cables are on the shorter side, making clean routing difficult in full-tower cases.
- Lacks a native 12VHPWR cable, requiring bulky adapters for newer RTX 40-series GPUs.
- Only carries a 5-year warranty, which falls short of the 7-to-10 year guarantees from premium brands.
Dimension Scores
Delivers stable 80+ Gold efficiency and 54A on the 12V rail, but 650W limits future high-end GPU upgrades.
The 120mm hydraulic bearing fan is quiet at idle but gets noticeably loud when pushed past 500W.
Internal components are decent for the price, but the 5-year warranty trails the 10-year standard of premium competitors.
The non-modular design forces you to hide thick, permanently attached cables, and the CPU cable is too short for large cases.
Best For
- Budget 1080p or 1440p gaming builds using mid-range GPUs like the RTX 3060 Ti or RX 6700 XT.
- Micro-ATX cases with a dedicated PSU shroud to hide the permanently attached cables.
- Upgrading older pre-built office PCs like Dell Optiplexes to support dedicated graphics cards.
Not Recommended For
- High-end 4K gaming rigs with RTX 4080 or 4090 GPUs that demand native 12VHPWR cables and 850W+ headroom.
- Mini-ITX builds where stuffing non-modular cables will choke system airflow.
Watch Out For
- Non-modular cable clutter — you must have a case with a basement or PSU shroud, otherwise the unused Molex and SATA cables will sit in plain sight.
- Short CPU power cable — if you are building in a large mid-tower or full-tower case, the 8-pin EPS cable might not reach the top-left motherboard socket without an extension.
- Adapter required for RTX 40-series — despite the marketing mentioning 40-series support, it only has standard 6+2 pin PCIe cables, so you must use the ugly Nvidia adapter dongle.

What Buyers Say
This PSU punches above its weight class for budget builds, easily powering mid-range rigs like a Ryzen 7 5700X and RTX 3060 Ti without crashing. The non-modular design is a major pain point, forcing builders to cram thick bundles of unused SATA and Molex cables into their case basements. Several users noted the CPU power cable is frustratingly short, barely reaching the top of standard mid-tower cases. While the 120mm fan stays silent during web browsing, a few reviewers mentioned it develops a noticeable hum after months of heavy gaming. Buyers accept the cable clutter because getting 80+ Gold efficiency at this price point is rare.
“It powers my 3060ti just fine and the price was great, but trying to hide all these extra stiff cables in my micro ATX case was an absolute nightmare.”
Common Praise
- Easily handles power spikes from mid-range GPUs like the RTX 3060 Ti without system crashes.
- 80+ Gold efficiency noticeably lowers wall power draw compared to older Bronze units.
- 140mm compact depth leaves extra room in the PSU shroud for stuffing cables.
- Includes four 6+2 pin PCIe connectors, offering good flexibility for older power-hungry cards.
Common Complaints
- Non-modular cables are stiff and difficult to bend around tight case corners.
- CPU 8-pin cable is too short to comfortably route behind the motherboard tray in larger cases.
- Fan noise becomes highly noticeable when the system draws over 400 watts.
- Lack of a native 12VHPWR cable means using bulky adapters for newer Nvidia GPUs.
Ownership Tips
- The fan curve is aggressive, meaning the fan spins up suddenly rather than gradually when launching a game.
- Dust buildup on the 120mm fan blades can cause a slight rattling noise after 6-8 months of daily use.
- The flat black cables look decent through a glass side panel, unlike the ketchup-and-mustard cables on older budget PSUs.
Frequently Asked Questions
Does this power supply come with the cables I need?
Yes, all cables are permanently attached to the unit. It includes the 24-pin motherboard, CPU 4+4 pin, four PCIe 6+2 pin, and multiple SATA/Molex connectors.
Will this work with an RTX 4070?
Yes, but you will need to use the PCIe to 12VHPWR adapter dongle that comes with your GPU. This PSU does not have a native 12VHPWR cable.
Is the fan loud under heavy load?
Most users report the 120mm fan is quiet during normal gaming. If you push the unit near its 650W limit, the fan ramps up and becomes noticeably audible.
Can I use this in a Micro-ATX case?
Yes, the unit is only 140mm deep, which fits perfectly in smaller cases. Just make sure your case has room to stash the extra non-modular cables.
Does it support dual graphics cards?
It has four 6+2 pin PCIe connectors, which physically supports two lower-power GPUs. 650W is generally not enough total wattage for a modern multi-GPU setup.
Buying Guide
When buying a power supply, you are paying for the engine of your PC. A 650W unit like this is the sweet spot for budget to mid-range gaming, but it will bottleneck you if you ever upgrade to a flagship graphics card. Because this unit is non-modular, every single cable is permanently attached to the box. If your PC case doesn't have a hidden basement compartment (PSU shroud), you will have a messy nest of unused cables sitting in plain sight.
80+ Gold Certification
This is like your car's MPG. Gold means it converts wall power to PC power with 87%+ efficiency, wasting less energy as heat compared to cheaper Bronze units.
Non-Modular Design
Think of it like a multi-tool where all the blades are permanently folded out. You get every cable whether you need it or not, making cable management much harder.
650W Wattage
This is the maximum total power the unit can deliver. 650W is plenty for a standard CPU and a mid-range graphics card, but will shut down if you try to run a top-tier card like an RTX 4090.
Alternatives
If you want a cleaner build without cable clutter, search for a '650W fully modular power supply'. If you plan to upgrade to a high-end graphics card soon, look for an '850W ATX 3.0 power supply' with a native 12VHPWR cable.
