    Power supplies, M2 vs Opus

    I am not sure I understand the difference.

    M2-ATX 160W Intelligent DC-DC PSU is a power supply, and it looks like there are many other perks. OPUS 150 watt DC-DC power Supply SFX.1215 is also a supply, but seems like it is lacking a lot of the bells and whistles.

    Just read some issues that people have had with the M2-ATX, so maybe that is an issue in itself, but looks like a much more feature-filled option.

    Opinions?

    As a side note... most of the PCs I see here are mATX based... for my own info, I have a few ATX power supplies for boxes at home, I will be able to use these while testing my setup, yes?

    Thanks.

    Most of the M2-ATX issues are with the Epia boards. If you are not using an Epia, you shouldn't have any problems. Also, I believe there is a fix for the early M2's but haven't really been keeping up with it lately.

    Also, make sure that you don't exceed the ratings of the power supplies indic=vidual power rails. Read this FAQ: Will <insert PSU model> Power Supply work with my system? for more information on power your system, and of course, there is always BugBytes FAQ here FAQ: Power Supplies Explained (Part 1)

    The OPUS and the M2 have the same features/bells and whistles.

    Thanks.

    I was looking at bugbyte's faq... must have just missed something.

    As far as the M2/OPUS, I guess just a matter of preference.

    I tried the M2 first and couldnt get it to work including a second modified by the manufacturer. I then got an Opus 150 and it worked right out the box. The M2 has more shutdown settings than the opus and also has the ability to cut the 5v line if you want it to where the Opus has to be modified to do this although it will shut the 5v down if your battery goes low. Of course another difference is the price with the Opus being more expencive. IMHO the M2 is built to a price and doesnt have good build quality, some seem to be working fine others have problems and some dont work at all. There seems to be a lot of returns on them. That said its also the new kid on the block and given the amount of units that they will sell they arent going to spend millions on R&D leaving us the consumer to iron out the bugs. I belive the Opus went through all the same stuff when it was new but its been out a good while now and seems to have everything sorted out.
    At the end of the day the choice is yours really, you can save a bit of cash and take a gamble or you can spend a bit more and get something well proven.

    I think I'll take the M2 option. Considering that I plan on buying one from here, I am thinking it will be in working order... even though used, at least it will be tested
