Choosing PSU

By wolfram
Nov 24, 2005
  1. I have a little problem choosing a PSU. I don´t need more than 300 W in my PC. I am in budget and want to spend no more than 27dlls. I selected two PSU´s from Newegg.
    It´s a COOL MAX. Is is a good brand?

    This one is a FSP Group PSU. I think is a good brand because my current PSU is FSP Group.

    Do you have any suggestions?
    My system specs:
    Intel Celeron @ 2.6 Ghz
    256MB DDR 400 Single channel RAM
    ATA 100 Barracuda 40GB 5400RPM drive
    MSi 661FM2 motherboard
    Crappy sis mirage graphics (planning to buy a Radeon 9550)
    Realtek AC 97 Audio

    Stay away from that first one you mentioned. It is on the list of makers that should be avoided.

    That FSP one looks ..... actually amazing for that price I have to say.

    Dual 12v rails totalling 32amps for that price? Wow. If 300w is enough to power your system (and it looks like it is) then I'd say that this is a good choice.

    Here is a good read on PSU brands:

    OK, now I will stay away from the coolmax PSU, so the fsp psu should be ok for me, i just want it for powering an AGP video card (perhaps radeon 9600?).
    I just don´t want to get my whole system burned.
    Any other opinion?

    I choosed this one:

    Just a question:
    Will this work with my MSI 661FM2 motherboard?

    This is my system config:
    Intel celeron 2.6GHZ
    MSI 661FM2
    ATA 100 40GB 5400RPM Seagate hdd
    Ati radeon 9600XT 256MB
    1 Cd-rw drive, 1 dvd drive
    1 floppy drive

    I think 300W is enough for my system. I heard the FSP psu´s are very good.
    My 200W PSU is from FSP and never failed.

    Go to the link below to confirm that 300w will be enough for you, but that PSU looks like an excellent one.

    It has a 20+4 connector for the motherboard, so that shouldn't be a problem either.

    Thanks for your response. I visited the link and discovered that my system should be PERFECT with the FSP 300W PSU. So I am going to buy it. I hope it´s 100% compatible with my MSI661FM2 mobo.
    Sorry to ask again, but, is it a problem the main connector 20+4pin, since my motherboard uses a standard 20 pin connector???????

    I researched this once before, and it seems that 20+4 can mean a couple of things depending on which company we are talking about.

    I just had a look at FSP's site, and couldn't find the info, but 20+4 can mean one of the following:

    1. It has BOTH a 20 pin and a 24 pin connector.
    2. It has a 20 pin connector with a 4 pin adapter to add for 24pin motherboards.

    And in both cases, you are fine as far as I can tell.

    Here we go, I found it. This is the motherboard connector that comes with your PSU. It is the 20 pin adapter with the optional +4 type.

    Thank you VERY MUCH DonNagual for answering my question. Now, i will buy it very very soon.
    Do you guys know if Newegg can ship to a P.O. Box using USPS service?
    Thanks for your help. This is the best site to get help :)
