Cooler Master MasterWatt 750W Semi-Fanless Modular PSU

Good product

Tengo una computadora que requiere bastante energia, con un i5-12400F y una 3070 ti que requiere una fuente que no cause problemas. Consistentemente nunca he tenido problemas con la fuente. Puede que en algun punto la cambiaria por una con una eficiencia más alta, pero hasta ahora no necesito hacerle nada. La tengo desde el 2022 y ya estamos en junio del 2024. Ha durado mucho, y realmente nunca me he dado cuenta del ruido, porque no suena nada.
La recomendaria si quieres una buena fuente, sin necesidad de gastar tanto, pero si puedes invertir en una con un mejor rating de eficiencia como podria ser una de nivel Gold o hasta Titanium, invierte, es para la seguridad de tus piezas. Yo que no tuve la oportunidad, aun asi no me dio ningun inconveniente.

The very reason I bought this PSU was because of the Gamers Nexus review that found it half decent and I can confirm it indeed is a decent cheap power supply.

Plenty of power, good efficiency, build quality is fantastic.

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
5) Warranty
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.

I got a new system (Lenovo Legion T5), but also a new graphics card (RTX 4060 Ti) that required a little more power. With help from a YouTube video as it’s been a while since I’ve tackled hardware and it’s always better to double-check, I was able to swap out this supply in about 10 minutes. It powers my graphics card, a DJ controller, a game pad, and my various USB devices just fine. Even when I’m gaming, I haven’t heard a peep out of the new box, noise-wise, and it’s about a foot from my head. I’ve never swapped out a power supply before. I’ve never specifically needed more wattage. I usually buy a new case with the power supply already in-place. So I don’t really have much of a comparison to offer with other supplies or ease of installation as compared to other units. All I know is this product met my needs and exceeded my expectations, both for ease of installation and performance.

EDIT NOV 2022:
Its still running! 24hr/365days full time security system w/9 cameras; 2 cctv & 7 wifi/ip type, all showing on two displays cloned (separate rooms) as a 9 camera grid. Still an early generation i5 cpu, 12gig memory, OS drive is 250gb SSD, plus two other conventional drives, and a bigger case, many 140mm fans, and two cctv to usb converters, bluetooth dongles and wifi input devices. all powered by this PSU!
Still winning. 😉

Original:
Mine is installed in a PC that runs a home security system w/9 cams, wifi & cctv, and has been silent and quietly running for over 2-1/2 years… and it died. Woke one day it was off. Troubleshooting showed PSU at fault. Verified with known working psu and with the test psu the computer fired right up.

Did the process with cooler master and had to pay shipping to them, but once they verified the unit they sent me a brand new replacement. It took a few weeks, but at least they replaced it and i didnt have to shell out for another.

On my Win-10 PC it seems more than capable, not sure why it died though?? I have a dust filter on my case where the psu draws its cooling air and it usually has minimal dust build-up. So i dont believe I’m getting above the Fans power-on threshold? Seems im not taxing the pc and psu too much. Otherwise the fan filter would have much more dust buildup, right? I think this is a good company, and though it took a bit, they absolutely honored the warranty! Bravo CoolerMaster!

I have it in powering an early i5 CPU, 12gb memory, geforce gtx 750 w/2Gb mem, showing on three HD displays, one @ 4K, two @1080. Three hdd’s; os drive is a Samsung 850 Pro SS Hdd, also a WD 1Tb blue hdd, 4Tb WD Purple.
OS is on the SSD, and all storage goes to the WD 4Tb Purple, the 3rd WD drive, wd blue, is where Win 10 was before i upgraded to the SSD for the OS and apps/software. So i left it in there for alternate storage.

This power supply has been running fine since install, but if after another 2.5 years it quits again then i might need a better model, but it might still be from this company since they just sent this brand new replacement!
