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 have a five year old version of the 700W PSU, and it is the only component in my PC that has never once given me a problem, and never once needed to be upgraded. I remember hesitating before pulling the trigger because it was a little more expensive, but I'm really glad I spent a little bit more because it has been well worth it.The PSU has been running SLI video cards (7800GTX -> 8800GT -> 460GTX) its entire life, along with a power hungry processors ([email protected]) and usually several HDD's and SSD's of various types over the years. It has never missed a beat in all that time.
I really wish there was a product like this in every segment of the PC industry. I've had countless problems with motherboards, memory, HDD's, SSD's, and even processors on occasion. If I could spend a little more on those other items and know that they would last without giving me grief, then I would do it every time.
Hopefully these PSU's are just as well made as they used to be, and if they are, then they definitely get a glowing endorsement from me!
Cheers,
Owen

whole, not hole :)Spazweasel - Wednesday, August 3, 2011 - link
Hole cooling is important. That painful burn can be a real buzzkill.raejae - Tuesday, August 2, 2011 - link
This is entirely meant as constructive criticism... but it seems this article was checked with a spell-checker and nothing else. The grammatical errors, misspellings, and sentence structure make it nearly unreadable... which is disappointing, because I'm very interested by these power supplies.cgramer - Tuesday, August 2, 2011 - link
Agreed. I think AnandTech needs to get one or more copyeditors on staff. Despite that, I still love their reviews. :-)SilthDraeth - Tuesday, August 2, 2011 - link
I believe English may not be this reviewer's native spoken or written language. I admit it was a bit difficult of a read, but really, it is a psu review.As long as the numbers on the charts look good. And the conclusion fits the bill, then I believe stressing over the oddly structured sentences is wasted energy.

I'm not stressing over it, really. I'm concerned mainly about AnandTech's image. Poorly-written articles (even if they're impressive for having been written by a non-native English speaker) reflect poorly on a site's or publication's level of professionalism. I'm noticing a lack of proofreading and editing in lots of publications lately, including extremely popular print magazines such as Motor Trend or Automobile. It's a shame, really, that quality of writing doesn't seem to matter as much in this online age.As I said earlier, though, despite the sometimes-rough writing, I do love AnandTech. It's the first place I go for in-depth reviews of computer-related products. :-)

Completely agree. I've always said this place could use just one competent copy editor. It'd make a world of difference in the professional image of AT, not to mention making the articles an enjoyable read instead of the tedious work it sometimes is right now.ajtyeh - Tuesday, August 2, 2011 - link
Sweet deal, it was on slickdeals yesterday, and a bunch of people got in, i cant belive you guys did a rewview right after i bought it. i have never known the reliability of PC power and cooling but after you did this review, it got rid of my buyers remorse.GO ANANDTECH

Still rocking a TurboCool 1200... Bow to me.
