Its capacity is 100 W higher than the V550 we already reviewed some months ago. This PSU's most notable feature are its incredibly small dimensions, which, combined with its decent capacity, grant it a high power density score, making it a good alternative to SilverStone's offerings targeting those who need a small PSU with enough throughput. Based on our experience with the V550, we expect it to perform well, although its high price will make things difficult in terms of its price-to-performance ratio, a key buying factor for most of you.
- Unique 3D circuit design offers higher efficiency and improves the heat dissipation
- Cooler Master's exclusive Silencio FP fan technology enhances airflow, reduces vibration and provides the best thermal performance
- Fully modular, flat cable design for better cable management
- 100% Japanese capacitors ensures an extended lifetime and minimizes power fluctuations
- Compact design 6.8W/inch3 fits perfectly with small form factor systems
- 80 PLUS Gold certified: up to 92% efficiency on typical load.
The V650 shares today’s standard of being a wholly 12V internal unit, with its lone +12V output rail providing 54 A or a total of 648 W. The +3.3 and +5 V rails output 25 A and 22 A respectively through DC-DC buck converters. Their combined maximum is rated at 120 W. Other than that there are the standard values for the stand-by supply (2.5 A) and -12 V (0.3 A) rails. Cooler Master states that the V650 has a complete set of protections, including OCP and OTP. It seems no different from the V550S in this respect.
SILENCIO FP FAN
HIGH AIR PRESSURE AND LOWER NOISE
The rotation speed stays lower in the Silencio while delivering high air pressure, meaning less noise. After 50% load, the rotation speed difference compared to double ball fans is 16% better in the V750, 22% in the V650, and 34% in V550.
TIGHT VOLTAGE REGULATION
The +12V rail is the most important part of a modern power supply as both the CPU and graphic cards are powered through it. Voltage fluctuations can cause system instability from high pitch noises
The V series provides very stable output under any sudden voltage fluctuations, meaning less stress on your precious components.
The V series are powerfully small. Not to be confused, it is still a standard ATX form power supply that one would expect to see in any computer, but shorter.
Only 140mm versus +180mm typical length - 22% smaller in volume! ATX form factor, but ideal for compact systems.
Powers all current high-end GPUs.
FULLY MODULAR CABLE
All cables are flat cable and black color ,including 24pin MB cable. Compared to old round cable design , flat cable can make cable management easier and cleaner ! A good cable management also allows you to have better heat dissipation in case and enhances your total thermal performance.
Any time you plug in, or, unplug the mains cable from the PSU I would personally recommend switching the V650 off first. While in most cases nothing will happen if you don’t, you could run the risk of shorting out something if there is a sudden power surge.
