A Detailed Look
The Corsair CS850M power supply features a scratch-resistant black matte finish and measures 160mm (6.3”) deep. The unit incorporates a large 140mm fan for cooling and the cables are a combination of fixed and modular.
The backside panel features an open grill and includes a power receptacle and master On-Off switch. The honey comb grill allows air to exhaust out of the power supply for cooling the internal components with minimal turbulence and noise.
The CS Series 850W modular power supply uses a 140mm Hong Hua fan (HA1425L12F-Z). The fan incorporates sleeve bearings and is rated for 0.22A and 1,800 rpm at 12 VDC.
In addition to the two fixed cables, the front panel contains six modular receptacles. All of the modular cables are flat, ribbon-style to help minimize air resistance and maximize case airflow. The two PCI-E cables measure 24” long (610mm) and the 4+4-pin ATX/EPS cable measures 26” long (650mm). Some users may also be looking for a second 8-pin EPS cable/connector and/or six PCI-E connectors instead of the basic four at this power level.
Under the Hood
Corsair is once again using Great Wall as the OEM for the CS Series Modular power supplies. The PSU uses DC-to-DC converters to create the 3.3V and 5.5V outputs from the +12V rail.
The dual main capacitors (Rubycon) on the primary are rated at 390uF, 400V, and 85°C. The secondary features a combination of electrolytic and solid polymer caps for filtering. Overall the layout and construction looks good.
CS units were always very
CS units were always very unreliable crap, even considering that they’re cheaper. The price-to-performance-to-reliability balance is just way off in these. If you need a truly high quality PSU from Corsair exactly, and for reasonable money, get HX line AT THE VERY LEAST, NOT the CS line. If you’re on a very small and/or tight budget you can get TX or RM units just fine, but for all sakes, I’m warning you, DO not buy CS units. They really suck some major rat’s ass, big time. If you want to spend little and get a decent unit, it’s either TX or RM, if you want a perfect high tier unit for reasonable price – HX, and if you want best of the best – AX (NOT an AXi, but the good ol’ AX).
Corsair built up a great
Corsair built up a great reputation in Power Supplies,
By primarily using SEASONIC units……………..
They have now moved to CHEAPER suppliers in their low
to mid range—MOAR profits-Don’t buy them……..
Corsair high end are good products-But why bother-
Just buy SEASONIC-You know your getting quality
components and quality built-Remember the PSU is the
most important part of your build……………..

It’s not CWT. You can see the mark “GW-ATX850SLA” on the DC-to-DC secondary board. GW means Great Wall. And all other CS units are also made by Great Wall. RealHardTechX is agree with me 🙂
Correct. It is Great Wall.
Correct. It is Great Wall. Which, in many cases, is a step up from CWT.
