5 out of 5 eggs

This review is from: CORSAIR CSM Series CS450M 450W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Amazingly impressed by this power supply. That's in line with what I read: Corsair is one of a few companies making great supplies.

The first time I turned this on I had to do a double-take -- the fan was turning but it was whisper quiet. There is a tiny audible hum, but that's it. And the cables and case look high quality and stylish.

Cons: The price. It had dropped due to a sale down near a 430W Bronze non-modular from the same brand, making this one a screaming deal in my mind. I would no doubt have been happy with the cheaper one, but with the Gold supply the computer will run cooler and therefore quieter while saving money. Not a cheap PSU, and you get what you pay for.

Last, apparently a "splittable" 8 pin CPU connector is a feature of many Corsairs, but it would be nice if that were documented on or near the product, to help first-time builders. My motherboard has a 4 pin connector and I spent a little time fretting that I'd bought an incompatible supply.

4 out of 5 eggsFantastic but Pricey

This review is from: CORSAIR CSM Series CS450M 450W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: -quiet operation
-clean black coating
-power cable included
-solid and heavy (not cheap light aluminum feeling)
-92% efficiency
-1 pcie 6 or 8pin connector for GFX CARD
-4 sata connector for HD/SSD
-3 peripheral 4pin molex connectors for CD/DVD DRIVES/ LEDS, etc.
-1 floppy power connector
-3yr warranty is nice

Cons: -semi modular cables (24pin and 8pin motherboard cables protrude from power supply)
-expensive at $90
-cables are not sleeved except for the 24pin atx
-short cables
-no led

Other Thoughts: This is a nice quiet and efficient power supply but at the cost of $90 it is a bit expensive considering it is only 450watts. It does run at a high efficiency which leaves no wasted power or heat. I use this for a single GTX660 on an AMD Phenom x4 and it works great. No power issues or shutting down; hibernate and sleep work without issues. If you want a reliable, semi-modular psu for a medium end single GFX card PC then go for it, but if you want a powerful, full modulated, and led psu then I would look elsewhere.

4 out of 5 eggsGood PSU

This review is from: CORSAIR CSM Series CS450M 450W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Its a Corsair PSU I have never had a PSU unit from them fail me cant say the same from other top vendors, semi modular which is nice for this price point, just used this psu for a computer i built for my son, gtx 780,i7 2700k oc, runs with out missing a beat. I really have to say one of the worst things is getting that melting smell that has never happened since i finally switched to using corsair for my builds. for me they are the standard thank goodness they have great QC.

Cons: I will say this every time but its the way things are now :(
MADE IN CHINA

Other Thoughts: for this price you know what your getting a reliable psu you know when you put it in a machine you wont have to have any worries about a fail

5 out of 5 eggsPrice is right

This review is from: CORSAIR CSM Series CS450M 450W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Can't say anything negative about this power supply, especially at its price point. Shallow unit at 140mm which makes it well suited for many ITX cases. This unit is good enough to power an i7 with a GTX 780 Ti and provide steady solid power. Fan is quiet enough to be able to be used in a smaller type case which are usually more exposed on a desk so noise matters more.

Cons: Would be nice if all the direct attach cables were sleeved. The modular cables are nice and flat.

Other Thoughts: The "Gold" certified rating is a a bit oversold in the market as are the levels of efficiency. The difference between Platinum and Bronze doesn't translate much in terms of money spent on power usage. However, the more efficient a power supply is the less heat it will give and more than likely the fan on the PSU will have an easier time of it and not kick in to high gear.

4 out of 5 eggsDecent PSU, maybe a little too premium for the PSUs in this range.

This review is from: CORSAIR CSM Series CS450M 450W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: - The 24pin motherboard power connector is covered in a braided sleeve.
- Amazingly quiet.
- Modular for the PCI-E and SATA/peripheral plugs.
- High quality components for a low wattage PSU.
- 80 PLUS GOLD certified.
- Solid construction and fairly light (for PSUs that is).
- Small enough that it can fit in some smaller cases as it is only 140mm. I put this in a Lian Li HTPC case (PC-Q08). I was initially afraid it would be too big, but I was surprised it fit with plenty of room to spare.

Cons: - 8pin power connector to motherboard does not have a braided sleeve. Why not sleeve both if you've already sleeved the other?
- None of the other cables are sleeved. Makes it harder to work with.
- 24pin and 8pin are both non-modular (hardwired). Technically, not a fully modular PSU.
- Product claims Multi-GPU ready but only provides 1x PCI-E plug? The end user pretty much has to go out and purchase a SATA or 4pin Molex to 6/8pin PCI-E converter in order for this PSU to support more than one GPU.

Other Thoughts: I put this PSU through two different testing environments. The first as a normal PSU for an HTPC/seedbox/file server, and the second as an secondary PSU in a 6 GPU mining rig.

The specs for my HTPC are as follows:
Intel Core i5 3450
8GB RAM
ASRock H77M-ITX
Crucial M4 64GB SSD
4TB WD Red

This Corsair pretty much beasted through the HTPC. The fans barely spun up even when the system was under load. Using a kill-a-watt meter, measurement from the wall never passed 250 watts.

For the mining rig setup, this PSU is powering (2 of 6) MSI R9 270s. Using a kill-a-watt meter, wattage from the wall for this PSU is about ~370 watts. The fan ramps up during the day when it is warmer, but still remains fairly silent. Fans from the video card drown out the sound of the PSU fan. The PSU has been running fairly strong under 24/7 operation, no hiccups so far.

450 watts and you get a semi-modular PSU that is Gold rated in a generally small form factor. A premium lower end PSU for sure. Most people building a PC and only needing 450W probably aren't looking to doing anything too heavy duty, so I am not sure the premium features of this PSU are really needed. A Bronze rated PSU probably will accomplish the same for less.

5 out of 5 eggsGreat PSU for the right environment

This review is from: CORSAIR CSM Series CS450M 450W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: + Semi-Modular configuration, with the required 24pin / 8pin motherboard cables being hardwired.

+ Included are the following connectors: 6/8 pin PCI-E, 4 SATA, 3 Molex, and separate molex to floppy adapter cable.

+ Gold certified PSU with around 89% efficiently at 90w load, 90% efficiency at 225w load, and 88% efficiency at 450w load.

+ With normal usage of a 20% load, very tight voltage regulation of less than 2% of ideal voltage of +12v, +5v, +3.3v.

+ Silent fan at less than 10db up to 50% load and gradually increasing to 20db at 100% load. For those looking to build a silent system meanwhile maintaining low volume air flow throughout the case, this would fit the bill perfectly.

+ Partial use of solid capacitors, which is not seen on lower end PSUs.

+ With the exception of the motherboard 24pin sleeved cable, the rest of the cables supplied are flat which will ease cable management, especially when routing behind the motherboard tray.

Cons: - Questionable payback time when comparing to cheaper Bronze certified PSUs (See Other Thoughts).

- Rather short 3 year warranty as noted on the product box. NewEgg, at the time of writing this review, states that the PSU comes with a 5 year warranty.

- Corsair does not manufacture the actual power supplies. CS450M PSUs are manufactured by Great Wall power supplies. Just for comparison, the CX430/CX430M are manufactured by CWT, and the ‘legendary’ discontinued Corsair VX450 (NewEgg Iem # N82E16817139003) was manufactured by SeaSonic.

Other Thoughts: The CS450M modular PSU is an update over CX430/CX430M PSUs offering higher efficiency certification of Gold than the Bronze certified CX430/CX430M line, as well as slightly higher wattage handling.

Something to seriously consider is whether it’s worth spending extra to get a more efficient power supply. Unfortunately the answer would be highly dependent on the computer configuration and uptime.

When testing the Corsair VX450, CX430M, and CS450M on a test system at idle, the following were the power consumption readings:

VX450 (80 Plus certified): 115 Watts
CX430M (80 Plus Bronze certified): 113 Watts
CS450M (80 Plus Gold certified): 107 Watts

Now to put those numbers into dollars. There’s 6 Watt power consumption difference at idle between the currently available CX430M and CS450M power supplies. If the system was ran 24/7, then this would amount to 7 dollars in yearly savings for using CS450M over CX430M. If we were to take an example of a 30 dollar price difference between the two power supplies, then it would take just a little over 4 years to recoup the price difference alone between the power supplies.

That of course can fluctuate greatly based on usage. If a lower end system is used which consumes half the power as the above test system and still ran 24/7, then the payback in electricity costs would be over 8 years. The payback scenario is unfortunately even worse when considering a more casual computer use of around 8 hours per day.

Overall the takeaway from Corsair CS450M is that it should be utilized in an environment where:

A. The payback time in electricity usage costs would be quicker (i.e. running a system consuming 300 Watts nonstop 24/7).

or

B. The end-user needs an absolute quietest PSU without having to resort to the premium priced fanless PSUs.
