PC Power & Cooling Silencer 760W & 910W

PC Power & Cooling, a part of the OCZ Technology Group, sent us two PSUs from their Silencer series. The 760W as well as the 910W version bet on strong 80mm fans which is unusual for modern products. Most Companies are interested in using larger fans since they can reach higher CFM per RPM. They try to reduce noise while increasing fan efficiency. But is that right?

First a larger fan can reach more components but therefore the airflow has an angle. From the fan to the PCB and from the PCB to the ventilation holes all PSUs with a vertical cooling have an angle of 90 degrees. Second a large fan is able to provide good cooling at his edges while the center gets problems. That's one reason why manufacturers make a lot of temperature tests for the transformer in the middle of a PSU. So finally the airflow is more direct with an 80mm fan but they can't cool the hole space on a large PCB. Sounds like a draw. In our opinion both solution have a right to exist. A lot depends on the internal design (heatsinks, arrangement of the components) and the position in your computer case.

It is no secret that Seasonic builds some of the Silencer products for PC Power & Cooling. We expect to see two robust PSUs with low ripple & noise results and a high efficiency. Since these Silencer are based on the S12D design (with an 80mm fan modification) both have an 80Plus Silver certification. With an SLI-Ready award and 7 years warranty OCZ wants to catch some enthusiasts. We will see if they can uphold one's reputation as a leading Company for professional products.

    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.
