The hallmark of the GX Series of power supplies is that they feature a single, highly robust 12V rail that efficiently and consistently delivers clean power to all of your critical components such as your processor, drives, RAM, motherboard, and graphics cards.

An included double-layer EMI filter, intelligent 120mm controllable fan, and an active PFC/PWM combo controller all contribute to the overall efficiency of the power supply. All of the many features found within the GX Series contribute to its 80 Plus Certification. This efficiency allows the power supply to utilize most of the power it takes in with minimal waste, saving your electric bill. It makes the GX450W a perfect addition to a home theater PC or mid-range computer setup.

5 out of 5 eggsCooler Master GX

Pros: Sturdy and Powerful.
Fan is quiet.
It is 80 plus bronze.
Works very well with Haswell CPUs.

Cons: Not Modular.

Other Thoughts: You need to really push in some of the power cables to get them to work. They're a bit difficult to put in the sockets.

1 out of 5 eggsdisappointed

Pros: very quiet and plenty of connector types

Cons: only 2 years old and the fan is already going bad. Opened it up and of course it has a proprietary connector on the fan so it cannot be replaced.

Other Thoughts: so disappointed in this product. i buy a lot of CoolerMaster power suppplies for my custom builds, but no more.

Manufacturer Response:

5 out of 5 eggs27 months and counting

Pros: Quiet
Price after rebate was very competitive for the wattage
Good connector flexibility
Dependable

Cons: Doesn't brew coffee

Other Thoughts: Got this 27 months ago, This was my first PS purchase, so I knew little to nothing about them and went with a list of brands recommended by people at PC support sites. This unit runs so quietly you have to eliminate all other noises in a room just to hear it. For a basic PC build that doesn't leech megawatts, this has more than enough juice. The connectors are quite supple and can be moved easily to accommodate tight case interiors. I'm a little surprised that the price hasn't dropped at all in a little over 2 years, but if I ever need a 450w or less PS again, I'd still buy this over taking a chance on anything else.

3 out of 5 eggsGX 450W

Pros: -Price point
-5 year warranty
-Protection systems work
-Japanese capacitors

Cons: -Bad ripple and unstable voltage on the 12V line
-Is not truly 80+ Bronze as advertised - only 80+

Other Thoughts: First, this power supply is only 80+ and the label on it shows this and is also noted in Hardware Secrets review and others. However, all GX 450 W's are now the D series manafactured by Enhace, which is better than the old E series 450's manafactured by Seventeam. A small plus for this PSU.

I was drawing about 380 W's with my system and it managed that, but monitoring with HW monitor and Asus Monitor showed it was only putting out about 11.48 to 11.5 volts on the 12 V rail. I decided to experiment and push it further to see what it would do, by adding components and OC'ing my processor to draw about 420 to 430W's and the voltages were all over the place. This is also noted in third party reviews. I then decided to push it as far as it would go and the protection system kicked in - as it should - and restarted the system. So it's protection system works well, but it for sure will not put out more than it's rated 450W's as another reviewer here said. So if you are using it for a low wattage build or in an HTTP system it will, suffice if you're not concerned about the fact that it's 12V rail will still only give less than rated voltage. Not acceptable by me though.

I replaced it with another much better PSU that almost rhymes with teatonic and the same monitoring tools showed the 12V rail never lower then 11.9. I considered warrantying or sending this back but what for? To get a new one that would be the same risk and pay shipping in the process? It is now my interim backup in case of failures on other machines

I wanted to like this PSU, and decided to give Cooler Master a chance, as they are working hard to rebuild their rep after some very cheap products, but I would only recommend this PSU for a low wattage system or a cheap interim backup to get you through, and even them it's iffy.

5 out of 5 eggsGood Power Supply

Pros: Does what is needed. Great for a basic first build. Good cable management. Looks nice. I had to upgrade for more attachments. There weren't enough power hookups for my graphics cards, only having one PCIE hookup.

Cons: I have had zero problems at all.

Other Thoughts: Just remember to calculate your power consumption needs when building! This may seem low compared to the 700+W (or more) supplies, but you may only be using 150W for a basic, or even 350W for a high end build with one card. Be smart, save money, and buy what your rig needs so you can spend it on other important parts.

5 out of 5 eggsVery efficient and quiet

Pros: known to be able to handle more then 750w with a breeze.

Cons: not known yet.

Other Thoughts: If it is not turning on, you probably didn't connect it to mother board right. DONT FORCE ANYTHING IN. IF the cords are right it should be going in with a slight nudge.

5 out of 5 eggsQuiet

Pros: Quiet. Like, won't even wake a baby quiet.

Cons: None

Other Thoughts: Serves its purpose and never had a problem with it. I had to upgrade to a high watt power supply when I bought my current graphics card. I have never had a problem with Cooler Master, which is also the brand I upgraded this to.

1 out of 5 eggsDied within one year and took my mobo with it

Pros: Quiet and worked well until it died

Cons: Died within first year of purchase and it took my mother board with it. Thought it was the motherboard bought a new one and found that my power supply went out too.

Other Thoughts: Currently in the process of getting it replaced. Lets see how it goes hopefully their not like asus

5 out of 5 eggsupdate review

Pros: Originally reviewed on 6/13/12, a review I neglected to put my name with.

This PSU has been in service for over a year and still performing as intended. Was originally a PSU for my server build but shortly after was used for a lite gaming rig for my boys. Now powering an Asus P8H77-V with i3-2120 and a GTX650 video, DVD, SSD and HDD, 4 case fans.

This is an active PFC which some have issues with a lower grade modified or simulated sine wave UPS when you lose AC power and it transfers to battery power.

I can confirm that that unit has no issues with the APC BE750G, when the plug is pulled from the wall, it doesn't miss a beat. This APC had two computers, a 23" Asus LCD, Netgear router and a Mybook Live NAS connected to the battery backup side when plug was pulled. No issues from any equipment.

Cons: none

Other Thoughts: Just recently upgraded this PC to the GTX650 which requires the 6 pin aux power, this PSU provides you with one of those connectors. Works as advertised.
