Noise Levels
| Sound Pressure Level (Ambient: 16dBA, 1m distance) | |
| Load | dB(A) (760W and 910W) |
| 10% | 18 / 19 |
| 20% | 19 / 20 |
| 50% | 19 / 20 |
| 80% | 25 / 27 |
| 100% | 34 / 36 |
| 110% | 36 / 38 |
These Silencer models have nearly the same type of fan speed regulation and an identical fan which means they show almost the same sound pressure level (or similar results with measuring tolerances). From 10 to 50% load the fan spins slow which is why the PSU is quiet overall. Starting from 80% the noise gets a little inconvenient. 110% finally is unbearable for sensitive ears. Only in comparison with the Turbo-Cool series we would say it is silent. According to the fan speed of other modern PSUs (Seasonic X-Series, Enermax Modu87+) both Silencer PSUs are too loud.
Efficiency and PFC
| 115VAC, 60Hz | ||
| Load | Efficiency (760W / 910W) | PFC (760W / 910W) |
| 10% | 82% / 79% | 0.910 / 0.899 |
| 20% | 86% / 86% | 0.935 / 0.928 |
| 50% | 89% / 88% | 0.967 / 0.965 |
| 80% | 87% / 87% | 0.982 / 0.973 |
| 100% | 86% / 86% | 0.987 / 0.979 |
| 110% | 85% / 84% | 0.988 / 0.984 |
| 230VAC, 50Hz | ||
| Load | Efficiency (760W / 910W) | PFC (760W / 910W) |
| 10% | 83% / 81% | 0.870 / 0.862 |
| 20% | 87% / 86% | 0.922 / 0.914 |
| 50% | 90% / 89% | 0.961 / 0.954 |
| 80% | 88% / 88% | 0.961 / 0.965 |
| 100% | 87% / 86% | 0.974 / 0.971 |
| 110% | 86% / 85% | 0.977 / 0.974 |
Here we can see some impressive results for 80Plus Silver products, specially the 760W model performs very well with up to 90% efficiency satisfying. The 910W version could be more efficient during 10% load. Nevertheless both samples are able to reach the expected results. Even at 100% load both models stay above 86% efficiency. The 760W PSU shows a power factor close to 0.99 (115VAC).

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.abscode - Wednesday, August 3, 2011 - link
Perhaps I am in the minority, but I will pretty much never consider any PS without modular cables.Beenthere - Wednesday, August 3, 2011 - link
Many people like them but I prefer PSUs without modular connectors. To each his own.7Enigma - Wednesday, August 3, 2011 - link
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! :)http://daphault.com/share/i7980x-2xl.jpg

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.abscode - Wednesday, August 10, 2011 - link
