Voltage Regulation
| +3.3V Regulation | |
| Load | Voltage (760W / 910W) |
| 10% | +2.00% / +1.83% |
| 20% | +1.95% / +1.52% |
| 50% | +1.47% / +0.30% |
| 80% | +1.02% / -0.61% |
| 100% | +0,79% / -1.52% |
| 110% | +0.53% / -1.83% |
| +5V Regulation | |
| Load | Voltage (760W / 910W) |
| 10% | +1.34% / +0.20% |
| 20% | +1.26% / +-0.00% |
| 50% | +0.26% / -0.40% |
| 80% | -0.02% / -1.60% |
| 100% | -0.40% / -2.60% |
| 110% | -0.73% / -2.80% |
| +12V Regulation (Worst Rail) | |
| Load | Voltage (760W / 910W) |
| 10% | +2.70% / +2.33% |
| 20% | +2.51% / +2.08% |
| 50% | +1.18% / +1.00% |
| 80% | +0.67% / +0.63% |
| 100% | +0.55% / -0.25% |
| 110% | +0.23% / -0.42% |
Here we can see that the 760W version is slightly better than its big brother. Well, the voltages start very high but therefore our 760W sample has hardly any voltage drop. -2.80% is the worst result we can see for the 910W PSU -- still a decent result. Everything works within the ATX specification which is nice to see.
Ripple and Noise
| +3.3V Ripple Quality | |
| Load | Ripple and Noise (760W / 910W) |
| 10% | 5mV / 6mV |
| 20% | 6mV / 8mV |
| 50% | 9mV / 10mV |
| 80% | 10mV /13mV |
| 100% | 11mV / 15mV |
| 110% | 13mV / 17mV |
| +5V Ripple Quality | |
| Load | Ripple and Noise 760W / 910W |
| 10% | 9mV / 10mV |
| 20% | 12mV / 13mV |
| 50% | 18mV / 21mV |
| 80% | 22mV / 24mV |
| 100% | 24mV / 25mV |
| 110% | 25mV / 27mV |
| +12V Ripple Quality (Worst Rail) | |
| Load | Ripple and Noise 760W / 910W |
| 10% | 10mV / 19mV |
| 20% | 21mV / 23mV |
| 50% | 22mV / 26mV |
| 80% | 24mV / 28mV |
| 100% | 27mV / 32mV |
| 110% | 28mV / 34mV |
In our summary we wrote that a typical PC Power & Cooling product should have low ripple & noise results. Here you are! Specially +3.3V and +12V perform very well with up to 0.29% and/or 0.34% ripple & noise (910W). The 760W model shows even better results here. On +5V we can indicate passable measurements (0.54%)

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
