GX 450W 02/24/2014
This review is from: Cooler Master GX - 450W Power Supply with 80 PLUS Bronze Certification
-5 year warranty
-Protection systems work
-Bad ripple and unstable voltage on the 12V line
-Is not truly 80+ Bronze as advertised - only 80+
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.
We apologize for any confusion you had with our power supply. The unit in question that is sold on newegg and the unit you mentioned in the review are different power supplies. The unit on newegg is indeed 80 plus gold (D series as you mentioned). The 80+ version is indeed 80 + and the 80 Gold sold here is 80 Gold. We are not sure if you were speaking of the general or your specific model, but if you were speaking of the line, hardware secrets has no problems with the ripple. So if you had trouble with the ripple, we can definitely help out with a replacement.
In regards to the 12V rail reading, motherboards require a base load of 11.4 to run according to the ATX 2.3 standard, with a max of 12.6 on the 12V line
If you have further questions regarding the ATX standard, the power supply in question, please do let us know.
