    Hi

    I have built new pc
    Its Core i-3, 4 GB RAM,500 GB Toshiba HDD, 1 DVD-RW &
    Intel H61BF OEM board.No Graphics & other add on PCI-e cards.


    SMPS is very important factor for a healthy system.

    I have zeroed following

    Cooler Master Silent Pro Gold 550 Watt (80 Plus Gold) OR
    Cooler Master GX- II 550 Watt. (80 Plus Bronze)

    But I am in doubt about 80 plus certification.

    Silent Pro Gold has 42 A on 12 Volt rail & it consumes 504 Watt
    GX II has 44 A on 12 Volt rail & consumes 528 Watt.

    Means Silent pro Gold 550 Watt- 504 Watt = Wastage watt is 46 Watt

    & GX II 550 Watt - 528 = Wastage Watt is 22 Watt

    GXII has less wastage than Silent Gold


    My assumption is 80 Plus Gold should have less wastage of watt.
    & 80 Plus Bronze should have more wastage of watt.

    But here is reverse fact. How this is ?

    For which one I should go ? Any expert opinion ?

    @bhai , this is not the answer you are looking for, but my question is, why do you need a 550 watt psu ? Your system will run happily even with a 450 watt psu. Even cards which doesn't need additional power supply will run, but your system is plain jane without any hungry power requirement right ? Or you have plans to add one in future ?

    Currently I am using Cooler Master Thunder 450 Watt (Without 80 Plus Certification)
    It has dual rail 21+18=total 39 Ah

    If I go GM450 (With 80 Plus Bronze) it has single 34 Ah which is
    less than CM thinder 450 Watt.

    Then which is better ?
    CM Thunder 450 (39 Ah) or CM 450M (34 Ah) ?

    I mean of CM 450M has 80 plus bronze then it should have more Ah than non 80 Plus certification.

    Comment by Snapdeal customer :
    The price is too good Bhai if you are not looking for any power hungry PCI-E upgrades, however if you have more to add in pipeline, better to go for the 80 plus types you want. Certification should mean reliability along with energy efficiency.

    Bhai do go for BIOSTAR motherboards even over an original Intel one. Much better manufacturer. Perhaps better than Asus and Gigabyte. Very less rate of failure and nice performance always.

    Another popular brand with a claimed MTBF of 11+yrs. Loads of protection too.

    BTW both are 80% or more. So do they couldn't be too far off in terms of 80plus certification standards.

    Thanx

    I have brought Cooler Master G series having 500 watt.
    It has single rail 38 Ah & 80 Plus Bronze certificate.

    It is more better than CM Thunder 450 Watt.
    Less humming than CM Thunder 450 & better build quality also.

    Little bit heavy than Thunder 450.
    OEM of Thunder 450 is CWT while G500 is made by Enchance.

    One doubt -

    When I use Thunder 450 with my new core i-3 system it runs cool.
    Even it doesn't get warm also.

    But when I installed it in old Pentium-4 having 845 GLLY board & 512 SDRAM, it becomes little bit hot.

    On old P-4 system it is getting warm means does old P-4 system consume more power ?

    If yes then may I go for 500 watt for my old one P-4 system?

    Yes P4s were power hungry. The chip fabrication process and resultant TDP figures are much higher compared to output performance by todays CPU standards, also resulting in more cabinet heat and higher fan speeds, also needing more cooling for older PSUs. So like you said it would demand more power for sure. Dont buy expensive 80+ PSU for P4; go for entry level PSU of any brand like I-BALL, Zebronics or an older VIP etc. and better still make sure you can get carry-in repair/replacement warranty for the same. Using a UPS with Stabilizer or small servo power stabilizer at minimum is a good way to enhance PSU life.

    Often neglected is a MotherBoard which should compliment the overall Thermal design efficiency. For example here is a good motherboard that has great on-board power regulation features.

    While installing OS make sure ACPI feature is working with all OS drivers, sometimes needed is latest BIOS flashing for the Intel 845GLLY mainboard for better ACPI support.

    It is a combination of a ULV cpu, with 80+ PSU, plus efficient MB and a proper OS configuration that allows PC to go to ACPI suspend/standby (all fans off) after preset idle time, that will make an efficient system.

    Best of Luck..!

    What is ACPI feature ... sometimes needed is latest BIOS flashing for the
    Intel 845GLLY mainboard for better ACPI support.:confused:


    BTW IMHO we should avoid Zebronics/iball cheap SMPS. They give various problems of automatic reset/shutdown etc. It can ruin board/processor also.

    So many users of iball/zebronics have mentioned these type of problems.

    Even I also got this experience. There was random reset problem to my
    brand new i-ball SMPS. That's why opted branded SMPS.

    Always use reputed brand SMPS.
    e.g. Antec/Cooler Master/Corsair/Enhance/Huntkey/Sisonic etc.

    I agree about the local brands, all local and foreign brands get these things manufactured in bulk from China only perhaps assembling here. Therefore improving margins without investing in component level manufacturing and limited accountability towards customer support. I suggested this since the system is an older one and PSU will cost 1/3rd and esp. in Mumbai the cost of repairing PSUs can be as low as Rs.150 to 250 and also the fact that you need to approach the local shop where you bought the PSU from to get faster support.

    Anyways do whats best suited for your conditions and business environment.

    Issue of warm smps to old P-4 solved. Hardware technician who done overhaule & cleaning of pc
    had made wrong connection of CPU fan while refitting.

    He had plugged cpu fan power connector in rear fan power connector. I corrected mistake.

    Now SMPS is not getting hot. In fact after using system for many hours
    it is running so cool that as it just turned ON.
    It is running like its name. Cooler Master

    Cooler Master rocks !
