The Cooler Master V850 V2 Gold can support a magnate-hungry RTX 3090 if you can find and afford one. It achieves high overall performance, and its program is efficient enough to save you money on electricity bills. With a bit higher performance, it could follow included in our prizewinning PSUs clause.
However, overall, it is a trade good product worthy of your attention. Its major competitors are the Seasonic Direction Plus Gold 850, Corsair RM850x and RM850, XPG Core Reactor 850, and the Big Flower Leadex III and V models with related capacity.
The 850W class is of squeaky interest recently since the new high-end art card game, including some of the best nontextual matter cards, from Nvidia and AMD demand inviolable power supplies. If you don't want to pay the RTX 3080/3090 graphics cards' bounty prices, you can settle down with a lower capacity whole of the Gold V2 wrinkle, which ranges from 550W to 850W. There are also white edition Metallic V2 models available if you ingest a white chassis.

Cooler Master teamed with Gospower for the V2 Gold line, an OEM that no other major brand uses indeed further. It seems that CM has an exclusive agreement with this OEM, using its designs in single of its products, including its hefty SFX units. The V850 V2 achieves Gold in the 80 Advantageous scale, patc in Cybenetics, information technology gets a Atomic number 78 valuation. Information technology also features silent operation, with lower berth than 30 dBA general noise output at modal operative conditions (Cybenetics A-).

There are deuce EPS and six PCIe connectors. IT is nice that this PSU has three PCIe cables, which you can use in super steep-end VGAs with triplet PCIe sockets. Please note that it is best to obviate using both PCIe connectors of the same cablegram in high-wattage art cards like the Nvidia RTX 3080 and RTX 3090.
The number of peripheral connectors is more than enough, but it is a shame to see such a small distance between them. Last, at that place are no in-cable caps, which is a major asset.

Overall Photos
Gospower provides this platform, and the designing is modern. What caught my eye is the insane number of mucilage misused in the transient filter to go along coil whine in hold in. It looks like they really wanted to suppress coil whine, so they didn't go cheap on the glue!
Gospower old an anonymous manufacturer for the FETs on the first side instead of the usual and expensive ones, but it has faith in them given the long warranty. The parts on the secondary side are of adenoidal quality, and an impressively high amount of polymer caps is used.
Transient filter
The transient filter includes all necessity parts, and on top of that, it has a set down IC to save energy on the hemorrhage resistors of the X caps.
There is an MOV to deal with voltage surges and an NTC thermistor and electrical relay combo, suppress inrush currents. Thanks to the high opposition of the aforementioned thermistor, inrush currents are bottom low.
Bridge rectifiers
The bridge rectifiers are powerful just are provided by an undiagnosed, to us leastways, manufacturing business. It would follow overnice to utilise a holy heat sink or else of communion the same with the main FETs.
APFC converter
The APFC converter uses two Sanrise Technical school SRC60R140BTFE FETs and a single Cree boost diode, which is regnant! The controller is a Champion CM6500, which is hanging away a CM03AX Intelligence Community. Lastly, the majority ceiling is by Toshin Kogyo, and its specs look acceptable.
Primary FETs and primary transformer
A pair of Sanrise Tech FETs are used arsenic primary switchers. They are installed in a half-bridge topology, and an LLC resonant converter is also utilised to boost efficiency. The resonant control is a Champion CM6901 IC.
12V FETs and VRMs
Six NCE Power FETs deal the 12V railing, while the nestlin rails are generated through a pair of Direct current-DC converters.
Filtering caps
There aren't more electrolytic caps, but the ones that Gospower misused are of superiority. Most ripple filtering is done through polymer caps, which are of high quality as healthy.
Modular board front
There are oodles of polymer caps at the face of the modular board.
Non often to see on this side. Soldering quality is decent demur for some parts where they had to heighten the PCB traces.
Cooling system fan
The cooling lover is of good quality since it uses a fluid dynamic bearing and a goody-goody manufacturer, Hong HUM, provides it.
