The Interior



Both PSUs are cooled by a AD0812UB-A71GL from ADDA, a very common brand for Seasonic-made products. The 910W model has larger main caps but overall it is the same layout as you can see on the pictures. Since the original S12D was a 750-850W design we assume our 760W sample will show a better performance later. This Interior is a great base for a PC Power & Cooling PSU since Seasonic offers a high-quality PCB, Japanese capacitors (Nippon Chemicon and Rubycon) and two very large heatsinks. The EMI filtering is well equipped and includes a MOV. The DC-to-DC VRM are realized on one PCB and use all solid capacitors from Nippon Chemicon.

There is not much space for cooling. Specially in the primary circuit where many chokes are glued together. The main transistors are two IPI60R125CP with a moderate drain-source resistance of 125mΩ. For rectifying on the secondary circuit Seasonic has implemented eight 40S45CT -- more than enough to provide 760 or 910W. In fact the conducting path behind are often weaker than the transistors and/or diodes for rectifying. Nice too see that this design has a 70 μm copper layer. The smaller version has a 12V coil with a HF litz wire.

    I thought PC Power & Cooling was phasing out these units in favor of their Mk II series units? The Mark II's have pretty poor build quality and power characteristics all around, according to JonnyGuru.

    I owned one of the original 750 Quad Silencers... great PSU up until the point it slagged the EPS12V connector on an ASUS Rampage II... no safety mechanism or anything else kicked in, the PSU just kept running and eventually melted the metal pins and plastic connector while I was in a game of TF2.

    The 760w and 910w PSUs are a new series of Silencer PSUs, not the older design that was phased out. The latest are Seasonic based while the Silencer II series is Sirfa based similar to OCZ branded models.

    Perhaps I am in the minority, but I will pretty much never consider any PS without modular cables.

    Many people like them but I prefer PSUs without modular connectors. To each his own.

    Honestly it depends on the case you are using. I was like you until I upgraded to a nice case that can hide any unused cables away from sight (and not block airflow). Then it''s just a minor nuisance when building the system. And it's one less point of connection failure.

    But honestly if the price was the same (or very close.....within 5%) I'd probably still go modular like you.

    Currently using a Lian-Li PC-B10; a very nice case, I think. I'm also the kind of guy who shortens or extends then re-sleeves cabling so I can route and hide then exactly how I want. What a nerd! :)

    I have a 910W Silencer that has been rocking for 2-3 years. Currently running 8 SATA Devices and a GTX 295 along with a 1090T X6 @ 4Ghz which runs 24/7. No problems what so ever. I think I paid $190 for mine back then. Great investment.
