AI Verdict
A solid 750W Gold modular power supply for builders who want a 10-year warranty and actually have a case with a PSU cutout to show off the RGB fan.
This PSU delivers reliable 750W power with excellent ripple suppression under 30mV, but the main selling point is the RGB fan. If your case has a solid PSU shroud, you are buying a lighting feature you will never see.
If your case hides the power supply, get a non-RGB unit with dual EPS connectors like the Corsair RM750x.

Pros
- Hits 80+ Gold efficiency with a peak 90% electrical efficiency rating
- Smart Zero Fan switch keeps the 140mm fan completely off when system load is under 20%
- Uses 100% Japanese 105°C capacitors for long-term reliability
- Built-in memory chip remembers your last RGB color setting after a reboot
- Backed by a massive 10-year manufacturer warranty
Cons
- Only includes a single 4+4 pin EPS CPU connector, limiting compatibility with high-end motherboards
- The RGB control button is on the back panel, making it annoying to reach once installed
- The Sirfa-built platform struggles with 3.3V load regulation compared to top-tier rivals
- Fan bearing rattles when spinning up in zero-RPM mode if mounted face-down
Dimension Scores
Achieves 80+ Gold and <30mV ripple noise, but 3.3V load regulation is mediocre on this Sirfa platform.
Smart Zero mode keeps it dead silent under 150W load, though the fan can rattle on spin-up.
Features 100% Japanese capacitors and a 10-year warranty, but the primary FETs are from a lesser-known Chinese brand.
Fully modular with flexible, flat black ribbon cables that are easy to route.
Best For
- Mid-range gaming builds using cases with exposed PSU cutouts or tempered glass basements
- Users who want a semi-passive silent PC for web browsing and light workloads
- Builders who prefer flat, ribbon-style black cables for tight cable management
Not Recommended For
- Modern cases with solid PSU shrouds that completely hide the RGB fan
- High-end CPU overclockers who need dual 8-pin EPS connectors
Watch Out For
- The RGB fan is practically invisible in 90% of modern PC cases because of solid PSU shrouds.
- If you mount the PSU with the fan facing down, the fan bearing often rattles every time it spins up from zero-RPM mode.
- Thermaltake requires you to cover return shipping costs for RMAs, which users report runs around $40 out of pocket.
- There is no software control for the RGB lighting on this specific model—you have to physically press the button on the back.

What Buyers Say
The 10-year warranty and stable power delivery win points, but the RGB feature causes immediate buyer's remorse for many. Users frequently realize their PC case's PSU shroud completely blocks the light show. A recurring mechanical complaint is a distinct rattling noise when the fan transitions from 0 RPM to spinning. Owners discovered this rattle can be fixed by mounting the PSU with the fan facing up. The flat modular cables get high marks for easy routing in tight spaces.
“Great power supply and the flat cables are awesome, but the RGB is completely pointless since my case has a shroud covering it up.”
Common Praise
- The zero-RPM fan mode keeps the PC completely silent during web browsing and video playback
- Flat, ribbon-style black cables are highly flexible and easy to route behind the motherboard tray
- The built-in memory chip successfully remembers the last RGB color after a reboot
- Handles power spikes from mid-range GPUs without tripping OCP or shutting down
Common Complaints
- The fan bearing rattles annoyingly every time it spins up if the PSU is mounted fan-down
- The physical RGB button is on the rear exhaust panel, making it a pain to reach
- Only includes one EPS CPU cable, which limits motherboard compatibility
- RMA shipping costs are high if the unit fails, forcing buyers to pay around $40 out of pocket
Ownership Tips
- The fan rattling issue in Smart Zero mode goes away entirely if you flip the PSU so the fan faces upward.
- Dust builds up quickly on the fan blades if mounted face-up, requiring more frequent compressed air cleanings.
- The 3.3V rail can cause slight stability issues with multiple high-draw storage drives over time.
Frequently Asked Questions
Can I turn the RGB lights off completely?
Yes. You can cycle through the colors using the button on the back of the power supply until the LEDs turn off.
Does the fan spin all the time?
No, it features a Smart Zero Fan mode that keeps the fan off under 20% load. You can toggle this feature using a switch on the back.
Will this sync with my motherboard's RGB software?
Not this exact model. This version relies on the physical hardware button, though Thermaltake does sell a separate 'Sync Edition' if you need motherboard control.
Does it come with two CPU power cables?
No, it only includes a single 4+4 pin EPS connector. You cannot use this with motherboards that require dual 8-pin CPU power.
Are the cables braided or flat?
The included modular cables are flat, low-profile black ribbons, which makes them easier to route behind the motherboard tray.
Buying Guide
When buying an RGB power supply, your PC case dictates whether it makes sense. Most modern cases feature a solid metal shroud at the bottom that completely hides the power supply, rendering the RGB fan invisible. You also need to check your motherboard's CPU power requirements; this unit only has one CPU power cable, while many modern boards require two. Decide if you want the fan to stay off during light use, as the physical switch for this is on the back and hard to reach later.
80 PLUS Gold
This is like a car's MPG rating. It means the power supply wastes very little electricity as heat, converting up to 90% of the power from your wall directly to your PC components.
Fully Modular
Instead of a permanent octopus of cables, you only plug in the exact wires you need. It keeps the inside of your PC looking clean and improves airflow.
Smart Zero Fan
The cooling fan stays completely off when you are just browsing the web or watching YouTube, making your computer dead silent until you start playing a game.
Alternatives
If your case hides the power supply, look for a non-RGB 750W Gold fully modular unit with dual EPS connectors.
