Antec Voltage Regulation and Quality

+3.3V regulation
Load Voltage
10% 3.41V (+3.33%)
20% 3.41V (+3.33%)
50% 3.39V (+2.73%)
80% 3.37V (+2.12%)
100% 3.36V (+1.81%)
110% 3.36V (+1.81%)


+5V regulation
Load Voltage
10% 5.16V (+3.2%)
20% 5.15V (+3.0%)
50% 5.13V (+2.60%)
80% 5.10V (+2.00%)
100% 5.09V (+1.8%)
110% 5.08V (+1.6%)


+12V regulation
Load Voltage best/worst
10% 12.18V (+1.50%) / 12.17V (+1.42%)
20% 12.17V (+1.42%) / 12.16V (+1.33%)
50% 12.12V (+1.00%) / 12.10V (+0.83%)
80% 12.08V (+0.66%) / 12.05V (+0.42%)
100% 12.05V (+0.42%) / 12.01V (+0.08%)
110% 12.03V (+0.25%) / 12.00V (+0.00%)

All +12V show almost the same performance and still stay above 12.00V at 110% load.+3.3V starts very high and reaches 3.36V at full load. The same goes for the +5V rail, which starts with +3.2% and ends at +1.6%.

Ripple and Noise

+3.3V ripple quality
Load ripple and noise
10% 4.70mV
20% 5.50mV
50% 7.20mV
80% 9.30mV
100% 9.70mV
110% 10.90mV


+5V ripple quality
Load ripple and noise
10% 7.30mV
20% 8.00mV
50% 9.30mV
80% 10.80mV
100% 13.30mV
110% 15.20mV


+12V ripple quality
Load ripple and noise
10% 7.90mV
20% 10.10mV
50% 13.80mV
80% 19.60mV
100% 21.30mV
110% 33.70mV

Holy moly! All of the rails have no remarkable transients and ripple is always below 50% of the allowed level. +3.3V only just exceeds 10mV (at 110%), which is impressive. Overall, these are exceptional results and deserve praise; we wish every manufacturer would do as well!

    Except guess what, PC Power & Cooling was bought by OCZ in 2007, and in 2010 they discontinued the Silencer and Turbocool lines permanently, and replaced them with the "Silencer Mk. II" line. It's the same thing as OCZ's "Z-Series Gold", only cost-down with some last minute jerry-rigged fixes that belie the half-arsed engineering involved, sold for half again as much as the superior OCZ counterparts.

    Proof that relying on a brand remaining consistently good for all time is a bad idea.

    Not sure where you've been, but pc power has been THE posers for a long time now. They got bought out as phaedrus just mentioned by OCZ years back and haven't made a great psu in many years. Reply

    You need to know which PC Power and Cooling PSUs to purchase and they aren't the pseudo OCZ models. Reply

    Uh what, an old ass turbocool 860 or 1200 that's massively overpriced, very loud, and overhyped...and also old as hell?
    I would never recommend PC Power to any modern computer user right now. Any high end Seasonic would blow it out of the water 15 different ways.

    Uh that is exactly a pseudo ocz model. Reply

    This review highlights what I think is the weakness of these PSU reviews.

    First, there's the issue of silly ripple testing. There is a spec for ripple. If you are inside the spec, that is good enough. There is nothing superior about having less ripple, it is a design choice. Sure, you can measure it on your o-scope, but show me ANY affect on system performance as long as the PSU is inside the spec. There is none. All the rest is an assumption, unsupported by any data, that designing to a smaller ripple somehow indicates better performance. Prove it, in the system outside the PSU. In the absence of such proof, I think such tests are simply means by which reviewers can assign bogus performance metrics to parts which are simply good enough, to satisfy perfectionists who want proof that their choice is superior.

    Second, there's the disassembly of the unit and the smug remarks on build quality, with copious amounts of electrical engineering jargon. That jargon exists only to convince the reader the reviewer is knowledgeable.

    That's good to know, but it doesn't make the reviewer or the review correct. All the snarky comments about how some unit doesn't meet the reviewers exalted standards for solder quality or cap ESR is puerile, useless crap. Look: can you _measure_ something wrong? If so, comment on that instead. Is the reviewer assuming his exalted standards will play out in the reliability or performance of the product? Prove it!

    The measures of output noise, efficiency, ability to carry full load, withstand hot conditions: those are valuable pieces of information. Cost is of course important. Even ripple measurements are fine, as long as you understand that inside the standard there's no difference. Build quality, though, is a subjective measurement very poorly linked to any data on reliability. If reviewers can't be bothered to find anything more substantive on reliability, they should at least have the humility to recognize the limitations of build quality observations and not be too dogmatic about it.

    With regard to this PCPC review, the reviewer seemed to fixate on a production mod capacitor jumpered rather than designed into the circuit board. Boohoo, cry me a river. Did it make any performance difference? If the reviewer hadn't opened the case, was there any actual functional difference? Is there any data, any data at all to indicate such a jumpered capacitor would be any less reliable? Chances are, many customers would actually get the next rev circuit board with the cap in place. At any rate, the generous warranty meant the manufacturer was putting its money behind it. Likely each jumpered unit was subjected to more rigorous testing because of the custom work.

    In short, the whole review obsessed on silly, subjective details while acknowledging the performance was fine. If they thought the unit was overpriced relative to performance, that would be fine, but that wasn't their complaint. The reviewer was probably biased because of his previous experiences with PCPC, but that's the danger of subjective metrics.

    Disclaimer: I don't work in the PSU industry, although I have a degree in that area. I don't own or have any vested interest in any of those products.

    Bought an 350W, 12 cm fan Seasonic power supply for some $100, in the times when the Athlon 4600+ (dual cores) were the mainstream from AMD - maybe three years ago, maybe more.
    Very happy I've been with it

    No mention of the weight of the power supplies? That's usually a dead giveaway. Reply
