    5.0 out of 5 stars Seasonic 650W M12II Bronze Series Modular PSU
    Reviewed in the United Kingdom on 25 February 2012
    Verified Purchase
    I bought this purely because my existing Seasonic PSU developed a fault with the fan when moving from once case to another.

    The new unit works quietly, reliably - thus far - and without any problems. But a note of warning here, the modular connections have changed type and will no longer fit earlier models. In other words, if you, like me, buy this as a replacement unit, you'll need to change over every single PSU connecting cable in your system.

    Oh, and this unit comes with a dual m/board ATX 12v cable, and it's important that you pick the right one to plug in. Get the wrong one, and not enough power will get to where it's got to go, and the unit may appear faulty.

    4.0 out of 5 stars Not quite as expected...
    Reviewed in the United Kingdom on 19 February 2013

    Previously impressed with the Seasonic brand, this psu seemed ideal.
    Particularly wanting a modular type, this model appeared to be most suitable.
    Unfortunately, the item delivered was only semi modular - not quite what I was expecting.
    I know that most of the 'fixed' leads would have been used anyway, and the rest could be used in future.
    So not really a problem? No - but a clearer product description would have been prefered.
    As for performance, it seems to work perfectly well, just as expected - so no complaints there.
    If you don't mind the 'semi' format, then I would be happy to recommend it.

    5.0 out of 5 stars Fantastic Power Supply
    Reviewed in the United States on 22 June 2013
    Verified Purchase
    Power Supplies get no love. They work or they don't work and get ignored after that. They're not flashy in most cases but carry quite a burden. I was delighted to find this at an amazing price on Amazon - the price as you might have noticed fluctuates by about $40 on any given day.

    I'm in the camp that a lot of folks over-buy their power supplies. Sometimes it's quite necessary, but a lot of times not. There are calculators out there to tell you what you need, and I always go over that for a general safety factor and the ability to add on. Solid State Drives, Hard Drives and even GPU's are drawing less power these days. Additionally, where I used to have several hard drives each with several platters, a SSD and big HD are all that's required now.

    Oddly, as PC parts get more efficient, Power Supplies actually have a harder job to do. Take the new Haswell chip from Intel. It's so power efficient that many power supplies fail when it tries to wake from a sleep state as the load is so low. In a weird way, power supply manufacturers have to make more efficient power supplies for more efficient PCs. That efficiency comes at a price with Platinum, Gold, Silver and Bronze rated power supplies. For my budget and needs for both size and power, a Bronze rated supply was what I was looking for.

    Luckily when I was buying parts as they came on sale in the weeks before the Haswell release, I purchased the very latest SeaSonic M12II 650. SeaSonic is well known and rightly so. They're one of only 2 brands I'd consider for a Power Supply and their reputation is beyond reproach. When I heard about the power supply issue with Haswell, I was confident that my still in the box PS would handle this issue, and I was right. These things are constructed to the highest tolerances in the industry. There are new models out there that can't handle the Haswell "feature".

    In the box you won't get an embroidered velvet carrying bag (although there is a fabric bag with drawstring) to waste your money on. What you do get is a semi-modular power supply that's going to fit into any mATX or other small form-factor case you choose. You'll also get a large assortment of additional power cables, in enough configurations to keep the internals of your case nice, clean and cool. The cables are top quality sleeved in open mesh, there is simply no issue here with that or the easy swap connectors.

    It's quiet, unassuming, solid, powerful and small. It's built by and backed by one of the very best in the business.

    Pros:
    - Semi Modular (MB 24 pin, ATX 12V 8/4, ATX 12v 8) for what you'll always need
    - Modular (PCI-E, Peripheral power, SATA and floppy) in a variety of configurations and number
    - 120mm double ball bearing quiet fan
    - Smart fan controller
    - Internal rubber mountings
    - High reliability 150° Japanese capacitors
    - Small form factor

    Cons:
    - Not free

    Sehr gutes Netzteil, einfache Montage, durch das Kabelmanagement braucht man nur die benötigten Kabel anstecken.
    Achtung für kleine PC-Gehäuse auf Abmessungen achten.

    Une alimentation certes chères mais très utiles. En effet modulaire, ce qui veut dire que l'on y branche que les câbles dont on a l'utilité. D'où un gros tas de câble en moins dans la tour, favorisant ainsi la circulation de l'air.

    Concernant les tensions & autres, pas assez connaisseur pour donner un avis dessus. Mais au vue d'autres critiques trouvées sur le net, c'est une alim qui est très bien notée là-dessus aussi. Bref, je la conseille à toutes les personnes désirant changer d'alim.

    Clean power, it is put together correct by the manufacture.
    5 yr. warranty.
    Single 12v rail.
    Powers just about anything new and most of the old systems.
    Energy Saving, 80% plus. Draws 9 amps at the wall plug.

    Con's
    Cables a little on the short side. ATX/EPS cable needs a extension added for taller cases. A very small item.

    Bought this from Warehouse Deals here at Amazon as used. The item suffered damage to the manufacture's carton as stated. One end was taped up, the cable end, with the cloth bag and screws. Power supply on the other end. Cables were in a sealed plastic bag. From all indications it was never run and perfect. Delivered on time. Price tag was close to half of normal. Upon delivery voltages checked, all there.

    Not a stranger to the Seasonic brand, and they build for others. XFX and Antec are 2 of many. A very good product.

    This one will end up in my own Intel Z68 rig, and should power it for a long time.
