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 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 (Q6600@3.6GHz) 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!

    whole, not hole :)

    Hole cooling is important. That painful burn can be a real buzzkill.

    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.

    Agreed. I think AnandTech needs to get one or more copyeditors on staff. Despite that, I still love their reviews. :-)

    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.
  • cgramer - Tuesday, August 2, 2011 - link

    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. :-)
  • Meghan54 - Tuesday, August 2, 2011 - link

    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.

    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.

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