Description

The Cooler Master Watt Bronze 650W is a modular 80 Plus Bronze certified PSU with a semi-fanless mode. Under 15% load, The masterwork Bronze 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. Dc-to- dc topology is employed to keep the voltage stable in all conditions. For increased performance, The masterwork Bronze 650 Watt is equipped with 16 AWG PCIe cables, which reduce resistance thereby increasing efficiency.

  • An alright cheap PSU
Size: 550W Pattern: Power Supply
I picked up this PSU for $48. At that price, it's not that bad. It is only 550 watts, so that limits what CPU + GPU combination that this unit can power. If you have a tiny build that uses the integrated graphics or low profile graphics, then this is a solid option. I never noticed the fan, but I also used in a very low powered system, so it may become more audible if you push it closer to the 550 watt limit. However, at time of this review, the price is around $80. This PSU is very budget limited model and is not worth it for that price. There are better performing 650/750 watt PSUs that make much more sense for the price and provide more options for your pc build. Overall, an alright PSU for sub $50 when priced accordingly. ... show more

  • I'm very happy I chose this PSU
Size: 650W Pattern: Power Supply
The best about this GPU is that you don't have to deal with cables that you don't need. It makes almost no noise, and installing it was a peace of cake. Is hard to find a better PSU for the same price.

  • Amo esta fuente semimodular
Size: 550W Pattern: Power Supply
Buena fuente, lo tengo con un r5 1600, ddr4 2x8gb, Gtx 970, 6 fans. No ha fallado y todo sigue funcionando bien, lo mejor es que es semimodular así que no hay tanto cable regado y no hay condición con los conectores

  • Warranty honored! Tnx, and after 2.5 yrs use too
Size: 650W Pattern: Power Supply
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! ... show more

  • Está bien por el precio
Size: 750W Pattern: Power Supply
La verdad por el precio, no esperaba menos, sin embargo, preferiría haber ahorrado un poco más y comprar una mejor marca, no viene con cableado enmallado y siento que es algo que me incomodó. Respecto al rendimiento sin problema con Ryzen 7 y una RTX 3080. El ruido si es moderado.
