AI Verdict
A solid 650W Gold modular unit with a 10-year warranty, but the RGB fan is a pointless gimmick if your case has a PSU shroud.
This is a reliable 80+ Gold power supply with high-quality Japanese capacitors, but you are paying a premium for an RGB fan. If your PC case has a basement shroud that covers the power supply, that extra money is completely wasted. It only makes sense for open-air chassis or older cases with exposed PSU slots.
If your case hides the power supply, skip the RGB and buy the Thermaltake Toughpower GF1 650W instead for better electrical performance at a similar price.

Pros
- 10-year warranty provides long-term peace of mind for a mid-tier unit
- Fully modular design with flat black cables makes routing behind the motherboard tray easier
- Smart Zero Fan mode keeps the 140mm fan completely silent when system load is under 130W
- Uses 100% 105°C Japanese capacitors for better long-term reliability than cheaper Taiwanese alternatives
Cons
- The RGB fan is completely hidden in 90% of modern cases that use a bottom PSU shroud
- Worse transient response and load regulation compared to Thermaltake's own GF1 series
- The physical RGB button on the back is annoying to reach if your PC is pushed against a wall
- Some users report noticeable coil whine when pushing the unit near its limits
Dimension Scores
80+ Gold certified and handles mid-range hardware fine, but transient response lags behind top-tier competitors.
The Smart Zero mode keeps it dead silent at idle, though the 140mm fan gets audible under heavy gaming loads.
Features 100% Japanese 105°C capacitors and carries a massive 10-year warranty.
Fully modular with flat black cables, meaning you only plug in exactly what you need.
Best For
- Mid-range gaming builds with an RTX 3060 or RX 6700 XT in cases with exposed PSU mounting
- Older case designs where the power supply mounts at the top and the fan is visible
- Builders who want hardware-controlled lighting without installing extra motherboard RGB software
Not Recommended For
- Modern cases with solid PSU shrouds that will completely block the RGB fan
- High-end systems with power-hungry GPUs like the RTX 4080 that need higher wattage and better transient response
Watch Out For
- The RGB lighting is controlled by a physical button on the back of the unit, not your motherboard software, meaning you have to reach behind your desk to change colors.
- If you mount this fan-down to pull fresh air from the bottom of your case, you won't see the RGB lighting at all.
- The Smart Zero Fan switch is right next to the power switch—accidentally flipping it will make the fan spin constantly instead of turning off at idle.

What Buyers Say
The most common realization buyers have is that they paid extra for RGB they can't even see. Because most modern PC cases have a metal shroud covering the bottom-mounted power supply, the 140mm Riing fan ends up facing the floor or hidden behind steel. Beyond the lighting gimmick, builders praise the unit's reliability and the flat modular cables that make routing easy. PSU enthusiasts on forums frequently point out that Thermaltake's non-RGB GF1 model offers better internal components for roughly the same price. The Smart Zero fan feature is a massive hit for keeping systems dead silent while browsing the web.
“Great power supply and the flat cables are awesome, but I feel like an idiot paying for RGB when my case completely covers the PSU basement.”
Common Praise
- Smart Zero switch keeps the PC completely silent during desktop use and web browsing
- Flat ribbon cables are much easier to route behind the motherboard tray than thick braided ones
- 10-year warranty gives massive peace of mind compared to standard 3- or 5-year guarantees
- Hardware RGB button is great for people who refuse to install bloated lighting software
Common Complaints
- RGB fan is completely invisible in cases with a PSU shroud
- Physical button on the back is annoying to reach if you want to change colors frequently
- Some units exhibit noticeable coil whine when the GPU pulls heavy wattage
- Electrical performance and load regulation are slightly worse than the cheaper Thermaltake GF1
Ownership Tips
- The RGB defaults to its last setting when you turn the PC on, so you don't have to reset it every time
- Dust builds up quickly if mounted fan-down, requiring you to clean the bottom case filter monthly
- The flat 24-pin motherboard cable can be stiff and requires some aggressive bending to plug in cleanly
Frequently Asked Questions
Can I control the RGB with my motherboard software like Aura Sync or Mystic Light?
No. This specific model only uses the physical button on the back of the power supply to cycle through 5 preset modes. You need the 'Sync Edition' for motherboard control.
Are the cables braided or flat?
They are flat, ribbon-style black cables. They don't have nylon sleeving, which makes them easier to bend behind tight motherboard trays.
Does the fan spin all the time?
Not unless you want it to. There is a 'Smart Zero Fan' switch on the back; when turned on, the fan stays off until the PC draws more than 20% load.
Will this fit in a micro-ATX case?
It is a standard ATX form factor at 160mm long. It will fit most micro-ATX cases, but you should measure your case's PSU clearance first, especially if you have a hard drive cage installed.
Does it come with the power cord for the wall?
Yes, it includes a standard heavy-duty AC power cable in the box, along with a storage bag for the extra modular cables.
Buying Guide
When buying a power supply, you are paying for reliability and clean power delivery, not just wattage. This 650W unit is plenty for a mid-range CPU and a graphics card like an RTX 4070, but you shouldn't buy it for the lights. Look at your PC case right now—if there is a metal box covering where the power supply goes, do not buy an RGB power supply. You are literally paying for a lightbulb you will lock in a closet.
80+ Gold
This is an efficiency rating. It means the unit wastes less power as heat compared to a Bronze unit, which lowers your electric bill slightly and keeps your room cooler.
Fully Modular
Instead of a permanent octopus of cables permanently attached to the box, you only plug in the exact cables your PC needs. It makes your build look infinitely cleaner.
Smart Zero Fan
Like a hybrid car turning off its engine at a stoplight, the fan completely stops spinning when you aren't doing heavy gaming, eliminating background noise.
Alternatives
If your case hides the power supply, search for a '650W 80+ Gold fully modular' unit without RGB to get better internal components for the same money.
