The Cooler Master V850 V2 Gold is a good power supply, able to support up to RTX 3090 graphics cards, if you can find one and have enough money to spend, of course. Gospower, the OEM behind this platform, did a good job under Cooler Master's supervision, offering good performance and high-efficiency levels on all load ranges (super-low, low, mid, and high). Moreover, the 5VSB rail is highly efficient.
We don't have any major complaints regarding performance. The only areas that Gospower could improve are the transient response at 3.3V and the APFC converter's performance. A little tighter load regulation at 12V would be highly welcome, too. Finally, a MOV in the transient filter would enhance this unit's protection features.
If you need a strong enough power supply to deal with one of the new and powerful graphics cards, either from Nvidia or AMD, the Cooler Master V850 V2 Gold fits the bill. It is a high-performance PSU with silent operation and good enough build quality, supported by a hefty ten-year warranty. It is in the same performance category as the XPG Core Reactor 850 and the Super Flower Leadex III 850. An older Seasonic Focus Plus Gold sample performs better, but we need to also check on the newest Focus Plus units and include them in our comparison charts.
