Corsair Csm Series Cs650m 80 Plus Gold Review
Corsair CS650M 650-Watt 80 PLUS Gold Power Supply Review
Corsair offers a very solid middle of the road PSU in terms of price, performance, and wattage with the CS650M. Let'south take a look now.
Rating: 89% Manufacturer: Corsair
Introduction, Specifications, Availability and Pricing
Corsair is a proper name that we're ever happy to see come across our test demote. Many of their products are second to none, and at the aforementioned fourth dimension, they are likewise industry firsts. This includes their AXi series power supplies, which were the beginning all-digital units available to consumers, with the ability to be monitored and controlled via software. It's been more than a twelvemonth and a one-half since the AX1200i hitting the market, and at that place's only been 1 other manufacturer to offering software that corresponds with their ability supplies.
But, it isn't ever virtually the high-end, bleeding edge technology that we see. There are a very large number of people that simply cannot afford to indulge in such equipment. Others accept no desire to buy into the latest and greatest, and just desire what is necessary to get the chore done. Finally, you have the ones who want something that is right in the middle of it all. This is right where the CS Modular series from Corsair comes into play.
Today, nosotros are looking at the CS650M, merely there are several other wattages bachelor, ranging from 450W to 750W. The CS650M is a semi-modular unit that performs relatively well, but besides has a reasonable price. Simply put, information technology is meant to be a bang-for-your-buck unit. Judging by the questions that I receive on a frequent basis, this seems to be what the bulk wants. This doesn't come as much of a surprise though, as most want to make sure they don't waste material their money. The best manner to do that is to start violent into the unit of measurement, and that is merely what we're going to do.
Specifications, Availability and Pricing
Corsair uses a single 12V rail for the CS650M. The 12V rail is rated for 51A, or 612W. Both the three.3V and 5V rails are rated for 25A each, with a combined maximum output at 130W. The 5VSB rails is rated for 3A, or 15W. Maximum combined output for the CS650M is 650W.
Corsair makes certain that you're not left out to dry when it comes to features for the CS650M. The unit of measurement features all of the protections that you want, including SCP, OVP, OCP, OPP, and OTP. The power supply features both native and modular cabling. All cables are of the flat ribbon blazon, with the exception of the 24 pin main, which is fully sleeved. The CS650M features an 80 PLUS Gilt efficiency rating, but it is not rated for 100% continuous output at 50C. Instead, Corsair does rate it for 100% continuous output at 40C.
Corsair has an MSRP of $109.99 on the CS650M. At the time of writing, we weren't able to discover information technology cheaper than that, just we were able to find it at MSRP at Newegg. Unfortunately, it comes beyond every bit a bit on the expensive side when compared to the competition. That doesn't brand this unit a bosom, but it does hateful that it will have to perform very strongly during our tests to stand out. Corsair backs the CS650M with a iii-year warranty.
Packaging
The packaging for the CS650M is very similar to what nosotros've seen with other models. In fact, it would seem as if they've only changed the color scheme, and not much else. The front gives us warranty, wattage, and efficiency information.
The back gives united states some more data. On the left half, we have a list of connectors available for the unit, along with some efficiency and fan charts.
This side of the dorsum lets us know that the power supply is Haswell compatible, has modular cables, and information technology also gives us the I/O specifications.
While the balance of the box doesn't take anything useful, this side does give a little fleck of compatibility information.
Inside the Box
The power supply is packed tightly inside the box with a little bit of bubble wrap to protect it.
The I/O specification characterization is located on acme, along with the serial number. The CS650M features a black end that is somewhere between a semi-gloss blackness, and matte black.
Both sides accept the aforementioned logos on them, with the opposite side existence inverted.
We have the on/off rocker switch, along with Air-conditioning input in the back. The honeycomb mesh grill takes upwards the residue of the space in the back of the ability supply.
There aren't too many modular connectors with the CS650M, but the ones that are there are clearly labeled.
The lesser of the power supply houses the 120mm fan with black wire grill to actively cool the ability supply.
All modular cables are of the flat ribbon type.
Inside of the box are an Air conditioning ability cord, a warranty pamphlet, and a prophylactic pamphlet.
Cabling System and A Wait Inside
Cabling Organization
The Corsair CS650M does a great task at making sure that there are enough cables and connectors to get the task done. The obligatory 24 pin Chief, and ATX 4 + 4 connectors are nowadays, alongside a pair of dual PCI-E cables. Peripherals are handled via iii more than cables, for a full of half-dozen SATA, and four Molex. At that place is also a Molex to FDD adapter included, in case you nevertheless need it. All cables are modular except for the Chief and ATX four + 4.
Rail distribution is as uncomplicated every bit it gets with a single 12V rail. At that place is no need to worry virtually load balancing here.
A Look Within
A pair of passive oestrus sinks takes care of most of the passive cooling for the unit of measurement. Coupled with the open air pattern of the unit, information technology should be more than than enough for a power supply of this wattage.
Two Nippon Chemi-Con capacitors reside on the primary side of the power supply.
The secondary side is filled with Taiwanese capacitors. In the motion picture higher up, you tin can run across both Teapo and Aristocracy caps. Our readers are sure to be familiar with Teapo by now, but this is the commencement Aristocracy capacitor that we take ever seen in a power supply on our bench.
Corsair uses the Ong Hua HA1224l12S-Z 120mm fan to actively cool the CS650M.
Examination Results and Final Thoughts
Examination Results
Our load tests utilise a couple of FAST ATE agile load testers, and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe, and a ability consumption meter. Yous can read more most our standard testing approach hither.
The tests performed are based around six conceivable setups that are out there, and progressively load down the PSU up to the power supply's limits, or 1000W; whichever comes first. Since our exam equipment'south limits are college than that of the Corsair CS650M 650W power supply, we tin can test it to the maximum.
The above tests represent typical loads that we have measured from various systems, and are meant to requite a rough idea of where your computer might autumn in line with our tests. Please keep in listen that each system is different, and bodily loads can vary profoundly, even with similar hardware.
Allow's outset by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rail, we come across 1% regulation from start to finish, with a full drop of .13V. The 5V track managed to stay within 2% of specification, with a total drop of .06V from outset to finish. Moving towards the iii.3V rails, nosotros run across that regulation was within 2% of specification, with a total voltage drop of .08V.
DC Output quality for the Corsair CS650M 650W was practiced, and well within specifications. During Test One, nosotros saw 14mV of noise on our scope. When nosotros increased the loads in Examination 2, the ripple climbed to 23mV at around half load. During Test Four, under a load of 650W, the oscilloscope showed a maximum of 33mV of noise on the 12V rail.
The Corsair CS650M 650W is rated for lxxx PLUS Gilded efficiency. This ways that the ability supply must perform at 87% / xc% / 87% efficiency, at 20% / 50% / 100% loads respectively. As you can see, the CS650M passed on our bench, and wasn't shut to failing at any point.
Final Thoughts
When Corsair set out to build the CS650M, they had a very strong vision in heed. That vision was to build a quality unit that would concenter the masses, and do so while keeping the price down, and so that information technology would entreatment to even more potential users. Afterwards going over the CS650M, and running it through all of our tests, I take to say that they have done a decent chore in doing just that.
The unit of measurement performs so well that it gives some enthusiast level units a run for their coin in terms of voltage regulation, and DC output quality. In that location are many high-end units that struggle to stay within 3% of specifications, while the CS650M barely manages to pitter-patter into the two% range.
On the other manus, Corsair also sought to offer the unit at a inexpensive price. $109.99 isn't bad for a 650W semi-modular unit, but it isn't not bad either, and therein lays the problem with this unit. There are more than a handful of units that come in cheaper than the CS650M that have the same features, or more. That alone will certainly hinder the minds of many when it comes down to choosing betwixt like units. New tech products almost ever hit the shelf with a petty bit of a premium that goes away later a few months.
If that is the example with the CS650M, then it is likely to get a much more attractive offering once information technology has $10-$fifteen stripped off the cost of the unit of measurement. Until so, it doesn't actually stand out in the most crowded segment of the PSU market.
