Internal Design and Components

Opening the unit reveals a typical Seasonic design with a 120mm fan blowing at the top of the heatsinks, so the heatsinks benefit in that case from a shape that will allow air to pass through vertically. There is a Nippon Chemi-Con cap installed on the primary circuitry, and the secondary features Japanese capacitors as well. PC Power & Cooling operates with a common forward converter with two MOSFETs (one high-side and one low-side one), which allows the manufacturer to use a higher switching frequency and lower voltage rating for the transistors. EMI filtering is well equipped with two common-mode chokes, another choke against differential mode EMI, six Y capacitors, two X capacitors, and one MOV. The ICs provide all the necessary safety functions such as OVP and UVP.

    I've mailed two of my PCP&C PSU's to Carlsbad, CA for custom recabling (connectors, lengths, sheathing) in the past few years, a service no other manufacture offers. I consider them to be quite alive and well, regardless of their OCZ inheritence. Reply

    I found that OCZ bringing PCP&C into their stable helped them a fair amount as they now had that companies expertise for the PSU's. Overall it didn't hurt PCP &C either as their quality didn't really go down..

    Ofcourse that can be argued here but this is a budget psu. OCZ should make their high end stuff under this brand. That's what we've come to expect from PCP&C

    Bought the Antec HCG-440M referenced in the article (as "same design") at Fry's, yesterday.

    $20.00 ($45 - $25 MIR).

    Advert says the sale price is good through 5/24; but I don't know if they still have any left.

    An excellent (not Seasonic based) PSU that I use a lot is the Chieftec A-80 & A-85 serie. Great power distribution, high efficiency, very silent and most of all, pretty cheap. If you live in Europe, I can highly recommend these PSU's. Reply

    I feel that a "seriuos" review cannot afford to omit physical dimensions of the tested psu.

    Because in that wattage size does matter, pointing at various itx and htpc cases.

    But how many PSU's in this range offer a 5 year warranty? Actually, hardly anyone offers 5 years anymore. Not Corsair, not Antec. This company does, and it was mentioned briefly at the end of the article. But I would be willing to pay a bit more for another two years over what most power supplies offer. Believe me, I've had enough fail just after the 3 year mark to really pay attention to this. Reply
