MasterWatt Semi-fanless Modular Power Supply
Power On With The MasterWatt
The MasterWatt is an 80 Plus Bronze power supply with an innovative semi-fanless mode. Under 15% load, the MasterWatt fan remains idle, offering zero dBA. When demand for power increases, a gradual fan curve provides measured cooling with little to no noise at any output level. Dual forward / DC-to-DC topology is employed to keep the voltage stable in all conditions. For increased performance, MasterWatt is equipped with 16 AWG power cables, which reduces resistance, thereby increasing efficiency.
- Semi-Fanless up till 15% load
- Dual Forward and DC-to-DC Circuit Design
- 5 years warranty
- More Conductive PCI-e Cables
- 80 PLUS Bronze Certified
- Durable LDB bearing
Dustproof and Silent fan
The MasterWatt has been equiped with the Cooler Master developed Silencio FP fan. This fan comes with the LDB bearing design with sealed construction features the highest dustproof level of IP6X and longer lifespan of up to 160,000 hours. The semi-fanless mode makes sure the fan operates at 0dB under 15% load. This means you can start to experience noise-free computing when doing regular PC work or when your surfing on web.
80 PLUS Bronze Certified
The independently tested 80 PLUS Bronze certification guarantees that MasterWatt delivers a typical efficiency of 85%.
Dual Forward and DC-to-DC Circuit Design
The Dual Forward and DC-to-DC circuit design offers reliability and stability. This is especially significant in +3.3V and +5V outputs.
More Conductive PCI-e Cables
The MasterWatt uses thicker 16AWG PCI-e cables. They provide less resistance increasing efficiency and safety.

Looks very sleek in the case, and the cables are all black. Semi-modular is perfect. Running an RX580 GPU, 2700X Ryzen 7 CPU, and ASUS ROG Hero Crosshair VII mobo, no issues.
Very quiet, haven't heard the fan yet, even under moderate gaming loads.
Also, the major differences between power supplies boil down to this...and these specs can be hard to find:
1) Built-in over temp, over current, over voltage, under voltage, short circuit, etc....many power supplies skimp on these and you risk frying your mobo or CPU if/when the PSU malfunctions (read about it, happens more often than mfrs care to admit)
2) Quality of electronic components and design....look for reviews that mention "coil whine" and avoid those unless you are deaf to frequencies above 10kHz
3) Quality/type of cooling fan (noise, reliability)
4) Rated efficiency
6) Cable management/modularity
...and of course, cost.
This PSU has all the protection features, a decent fan, a decent warranty, a decent fan, is quiet (large fan with a thermal control circuit...fan is actually OFF when under lighter loads...fan blades are designed to minimize noise), is 80+ rated for efficiency (close to 90% in fact), and the semi-modular cables do the job.
I shopped around for quite a bit, this particular series of power supplies hits the sweet spot for me for features and quality, vs. value.
It has a very annoying buzzing sound on load. Looked up the entire internet for a fix, and tried every missing piece (Add UPS, change cable, insulate screw-place contact with case.. etc), no success. Will update review based on customer service.
Update: The other one worked for two days then shut off and never ran again.
This product failed me twice now, and I just noticed it increased $22 in price from when I bought it (it was $50 and now it is $72)

Es un buen psu para alimentar tu pc, cabe mencionar que es un psu de rendimiento medio pero logra alimentar bien tu pc, siempre y cuando hagas un calculo de los componentes que requieren cierta energia.
Es de materiales de alta calidad, pero tiene unos cable muy gruesos y no te dejan maniobrar bien en el gabinete, sobre todo los de 24 pines que van a la mother y los 4+4 pines que alimentan el procesador (cpu).
Cuanto a ruido, es poco perceptible lo que genera, sin duda es un buen psu, pero ojo, no recomiendo hacer overclock al cpu o al gpu con esta fuente, aunque tengas watts de sobra, no esta diseñada para ese uso agresivo.
Only the 2nd or 3rd time I ever have changed a PSU myself. Not that difficult to accomplish. Very quiet.
Overall I am very satisfied with the product, if the 80+ gold version wasnt out of stock i would probably spend the extra $20 and get that instead though...
edit 04/06/20. i was happy too soon, very very bad coil whine when under psu load. I will probably return this for the MWE gold and see how that goes instead.
Cómo experiencia del reembolso pongo esta calificación porque lo regrese un jueves y literal al día siguiente, viernes, ya estaba mi reembolso por la tarde (eligiendo el reembolso en dinero para gastar en la app de Amazon) cómo iba a comprar otra vez otra fuente elegí ese método si no decía que podía tardar más tiempo
