4 out of 5 eggsCool and Quiet

This review is from: CORSAIR CSM Series CS750M 750W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: If you do a search here on Newegg for Power supplies and then filter by most reviews, chances are high that you are going to see many Corsair models. There is a reason for that, they have made a name for themselves over the years producing top quality components. This unit is no different and exceeded most of my expectations.

The first thing you will notice when opening the box for this PSU is the packaging. Besides the extremely high end products this is as nice as it gets. Although pieces of foam and cardboard don't affect the performance, people love to know what they just bought is quality and premium packaging definitely helps sell that idea.

Although this is a full sized power supply, I was able to fit it into a Mini ITX case (Cooler Master Elite 130) with no issues. In fact the modular cables really helped make sure no room was wasted with unused cabling and unobstructed air flow front to back.

Along with being in a smaller case, the whole machine is located in an entertainment center cabinet and is being used as an HTPC streaming content through the house. After a month of almost daily use I can confidently say that this things stays very cool and quiet while running 24/7. Having a Gold efficiency rating will almost certainly help with any power cost since I have yet another full fledged computer running day and night.

All in all there is much to like about this unit, however I do have a few comments and complaints...

Cons: And the biggest one of those complaints is the cables, more specifically the feel of them. For some reason that I can't quite pin point they feel somewhat cheap. The plastic isn't noticeably thinner, yet when plugging in some connections I was concerned with enough pressure I could snap a piece off. Chances are if you've built a PC in the past you know how stubborn some 4 pin molex connectors can be. Obviously not everyone even has a need for molex anymore, but if you're paying for a higher end product you expect that no corners be cut.

Moving away from the connectors and onto the cables, they are incredibly stiff and awkward to move/position. Maybe I classify this as an issue because my working space was so restricted, however I've noticed more people are scaling their builds down with powerful and efficient pieces. If you plan on building a Mini ITX build like myself, know that cable management is going to be an issue.

In stark contrast to the overall unit which oozes quality, I just am not happy with the cables or connectors. I don't exactly how much those plastic pieces cost but I certainly think a little more time and effort can go into the design for the price being charged. For that reason I am deducting one egg.

Other Thoughts: Minor niggle over the cabling aside, I would recommend this unit for anyone looking at a mid tier, 750 watt PSU. I had planned on switching this unit back out for what was in my HTPC prior, but it just runs well and unnoticeable that I have no reason or need to do so. However, do your research beforehand, most people don't need huge PSU's anymore unless you are building an enthusiast gaming or workstation rig. PC components have gotten so efficient in past years that most rigs could do with a 600 Watt PSU or less. Now it's always nice to have some overhead in case you want to upgrade in the future, but again thing's keep getting smaller and more efficient over time and if you don't need 750 Watts then you can use the extra cash on a better GPU or more RAM.

5 out of 5 eggsGreat PSU

This review is from: CORSAIR CSM Series CS750M 750W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: * 750 W Good for a Mid-range to Upper Mid-range

* 80 Plus GOLD (Has higher efficiency then 80+, 80+ Bronze, 80+ Silver)

* Well known Respected Brand. Doesn't matter if its RAM, PSU's, Cases, etc Corsair is well known for quality Products.

* Great Amps on a single 12v rail 62A. Great for powering 2 high end GPUs

* Supports Intel's Haswell C6/C7 Sleep States. PSUs that cant support these C States dont get the energy savings of these new modes.

* Extremely Quiet while under load

* Extremely Cool under load only a few degree above ambient room temperture

* Modular, use cables that you need, leave out ones you don't. Makes for a much cleaner look inside the case (and a lot less zip ties!!!)

* Cable Lengths are good and work well with both top and botton mounted cases.

* Contents come well packaged and secure. The PSU unit itself is encased in a good quality thick foam protective box.

* Great Customer Support

* ATX12v 2.3/2.2/2.01 + EPS12V 2.91 compliant included below are some notes from the Changes in the ATX12v Standard that each of these pertain to:
From Wikipedia
ATX12V v2.01
-A minor revision from June 2004. An errant reference for the -5 V rail was removed. Other minor changes were introduced.
ATX12V v2.2
-A minor revision. Specified High Current Series wire terminals for 24-pin main and 4-pin +12 V power connectors.
ATX12V v2.3
-Effective March 2007 and current as of 2014. Recommended efficiency was increased to 80% (with at least 70% required) and the
12 V minimum load requirement was lowered. Higher efficiency generally results in less power consumption (and less waste heat)
and the 80% recommendation brings supplies in line with new Energy Star 4.0 mandates.
The reduced load requirement allows compatibility with processors that draw very little power during startup.
The absolute over-current limit of 240 VA per rail was removed, allowing 12 V lines to provide more than 20 A per rail.
-Defined in SSI (Server System Infrastructure)used primarily by SMP/multi-core systems such as Core 2, Core i7, Opteron and Xeon.
It has a 24-pin main connector (same as ATX12V v2.x), an 8-pin secondary connector and an optional 4-pin tertiary connector.
Rather than include the extra cable, many power supply makers implement the 8-pin connector as two combinable 4-pin connectors
to ensure backwards compatibility with ATX12V motherboards.

* Powering my system like a champ under Load without issue for 9 days now (these reviews have to be in quickly, will update at 6-month and 1-year mark but I expect no issues)

Cons: * Does not have a bag for the unused cables. Some PSUs out there come with a nice bag to store unused cables.It helps you from losing them.
This Particular model does not come with any such bag, not worth removing an egg but it would be nice.
The higher End Corsair PSU do come with such a bag.

* Does not have the Digital DSP control like the Corsair AXi Series.

* The Cables are initially Stiff,

* If you are into the cryptoCurrency Fad you will want a higher wattage Power Supply for 3-4 Graphics cards.

Not a con of this product, but if price is not an option, Corsair does offer AXI/AX Product lines which are 80 Plantium which is of coarse a higher level of efficency then this model.
Product. So if price isnt an issue you can see more efficency between Gold/Platnium Standards.

***NOTE THIS CHART is for Reference to 80 Plus Standard***

80 Plus Platinum 90% 92% 89% 90% 94% 91%

Other Thoughts: Received this product for review. Package came undamaged. After removing the plastic wrap opened the package.
The contents are put in nice and tightly. The power supply itself is covered by a thick 2-piece high grade foam to prevent damage in transit.

Seeing how this unit is Modular,the PSU comes with plenty of cables more then enough to wire even a full size ATX tower with room to spare.
Cable length is generous, and the cables are initially a little on the stiff side.

Tried the PSU in a few different cases to get a good feel for it ranging from Full ATX to MicroATX cases. Top and Bottom PSU mounts. Worked well in all situations.

While at load the PSU was only 3c above ambient room temp.

To test this system. I used a few different CPU configurations. First my I7, then an I5, Then a FX-8350. For video card is used 2x Radeon 7870's(aka r9-270's nowadays).
I played Tomb Raider/Battlefield 4/and Call of Duty:Ghosts all on 1080p Ultra in order to stress the system and put as much load as possible on this power supply and get as close
to its max rated 750w in order to test reliability. I took FX-8350 (since it is the more power hungry of my CPU's) overclocked it to 4.7ghz, and plugged in extra DvD-Drives, and hard drives.
I was able to get my systems power usage 738w under full CPU and 2 GPU's at max load. So 12w shy of the maximum load of this PSU, I then played All games mentioned above for 3 hours stretches, 5 days in a row.
I had no failures or power spikes, or frame drops related to insufficient power. Over the past 20 years I had the chance to build, upgrade, or fix over 200+ computers so I seen every part imaginable fail.
This PSU survived what I could throw at it with the limited time I had(under 2 weeks).

I wish the package came with a bag for the cables like Corsairs higher end models, but I am organized so its not a huge deal, but it would have been a plus.
Overall for the price and performance of this power supply, you can not go wrong. For 90% of builds out there this unit will meet all your needs. Only ultra high end configurations, or bitcoin/litecoin miners would need a higher wattage supply for 3-4 Very High End GPUs, or

This unit is backed by a 3-Year warranty, and my personal experience with Corsairs support division has been excellent, compared to other brands which I will not name and shame.
There is a reason Corsair has a solid reputation for well over a decade. Quality of its products, and the support they give. Those 2 things are a rare combination.

A solid unit, It will be in my steambox to be used lets just say alot. Will update review if any problems happen.

The only true con is if money is no object there is Corsair's AXi line with 80+ Platinum rating, not to mention new Digital DSP. A tech nerd can dream.

5 out of 5 eggsPerformance and Quality +++++

This review is from: CORSAIR CSM Series CS750M 750W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Corsair has always been a very quality producing company. I have had many different products from them other the years and each one I have had I’ve greatly appreciated the build quality of it. And the CS series of Corsair power supplies is nothing short of amazing. I have a CS450M that use I in a test WDS (Windows Deployment Server) and it is perfect.

But for some great features about the CS750M are:
Quality shroud, not a poor quality one you would get with some other companies.

Fan is surprisingly quite even though it never turns off. In fact even running this power supply for a week 4 days straight it never once ramped up to the point where I could hear it. So for anyone obsessed with decibel ratings you won’t have to worry about this fan at all.

Naturally its 80+ Gold. Because it so efficient I can feel good about not consuming energy when its not needed plus it makes me smile knowing a company is trying to leave behind a good rep when it comes to our environment.

Modular cabling where the end connectors are clearly marked for any new-bee to computers. (Hey we have all been there)

Supports 4th Gen Intel processors. Which the reason this is so special and helpful is that computers today have what is called a “low-power sleep” Which when this tec is applied to a older power supply or poor quality power supply you will see a noticeable performance decrease with your system during a wake up or resume. And I do believe that all CS series have support for the new 4th gen processors.

Tech Specs:

3 Year Warrenty
Zero Rpm Fan Mode “120mm Fan”
EPS Connector= X1
Floppy Connector= X2
4-pin Peripheral Connector= X7
PCI-E Connector= X4
SATA Connector= X8

Cons: Not really a big deal but one on the semi-modular side. The Main power cable is set in a nice black mess sleeve while the secondary power is a flat cable which is not sleeved. Now the way I use the secondary is always to run it behind the motherboard, so 90% is out of sight. But for those that are neat-freaks and light consistent features this might annoy you a little bit. I’m fine with it but it is a little strange that they didn't sleeve this cable.

Can’t really say anything bad about this power supply, its well designed and well built.

Other Thoughts: Some people may wonder about the price but you get what you pay for. And yes you hear that all the time but I speak from experience, I used to buy the cheap parts and say this is good enough for me. But then I had failures and performance problems that just became a hassle. So I upgraded to first class and I don’t think that I will ever go back.
To corsair, good job on the power supply and I can’t wait to see what new features and products you have us in the future.

5 out of 5 eggsCorsair CS750M Gold Certified Modular Power Supply

This review is from: CORSAIR CSM Series CS750M 750W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: First off, having a system with a power supply delivering 92% energy efficiency grabs the attention right away. In the past we have run a home server plus three additional security camera servers all 24/7 at our home and business. We still run three camera servers and with a recent purchase of online digital imaging equipment, the home server will be needed again. In addition, with this unit we get the power and dependability necessary to run a powerful quad core machine and produce the highest quality two dimensional (or three dimensional if needed) medical/dental digital images possible. In addition, the over/under voltage protection, over power protection and over temp protection, are important considerations when considering the expense of a network server failing or being rendered useless due to power issues. The active power factor correction (active PFC) provides the advanced circuitry necessary to provide full spectrum AC input voltages of 99% accuracy regarding the CSM750's output voltages.

A few observations regarding the unit's appearance. The first noticeable attribute of the Corsair CS750M was it's size. The unit would fit beautifully into a lot of Micro cases we have built. This is a great feature in our opinion. The unit's size does not take away from it's considerable weight and overall high quality appearance. The prominent green and white CS750M company logos against the black matte finish generate a lot of eye appeal. The fully modular design allows for minimum cable clutter and provides a clean modern look.

Take note: If you are building with a micro case, the Corsair CS750M should be at the top of your list of PSU candidates.

After thirty minutes of operation the unit was slightly warm to the touch, but nothing excessive at all as far as generated heat. Corsair's CS750M design offers a single +12v line rated at 62A, The +5v line provides 25A as well as the 3.3v line rated at 25A. We checked the system's BIOS utility for voltage outputs from the motherboard. +12v =12.58v, +5v=5.04 and +3.3v=3.20v in BIOS utility. All voltages were steady with little or no fluctuation.

The CS750M's active PFC provides AC input voltages with 99% accuracy as well as being designed with Corsair's latest built in over/under voltage protection, over power protect as well as over temp protection. Add all this to the hefty 750w of power in a micro case friendly design and what is not to like? The CS-M Corsair series is a step up from the prior CS series when considering the many enhanced performance features the series has to offer. We love the small footprint and micro case build possibilities with this unit.

Cons: None.

Other Thoughts: Corsair does mention in their warranty the CS-M series comes with a 3 year warranty covering material and workmanship.

5 out of 5 eggsGreat PSU Wattage for the Size Needed!

This review is from: CORSAIR CSM Series CS750M 750W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Reviewing the CS750M power supply.

This power supply was a great find, because I wanted to make a mini-itx that was future-proof. Modern high-end GPUs demand close to 600w, and I'd like something that can deal with any increase in the future. Trouble is, my mini-itx case can't except PSUs that are over 140mm deep without bending the cables too extremely, and this PSU solves that problem. Super silent, competitively priced, booted without issue, and runs my gtx 770 4gb.

Cons: None, works as advertised.
