105 PSU in test

[toto408]

Matbe, a french/belgian site, tested 105 PSU in a big review:

Very nice.

Use the google translator, or something of the sort, to get the gist of the review.

Just spectacular.

ONE HUNDRED FIVE friggin PSUs and not a single PCPnC.

[Daveb2012]

I thought this was for a 105w PSU at first..

Might be due to the fact that PC PnC PSUs are not available in Europe.
PC PnC simply does not exist here.

Three food manufactured by Seasonic

:-D

Well not exactly I live in Greece and one of the bigger vendor here sells those PSUs here is the link http://www.plaisio.gr/productlist.as...1&category=916 .

Not exactly cheap at 489 Euros for the 1000Watt version considering that they also sell the Enermax Galaxy 1000watt (the new one) and the Silverstone Olympia 1000watt for 299 Euros. Also they have the OCZ 1000watt for 279 Euros so for me the PC PnC is simply not worth it.

x2.. *hugs his M12 700W*

[lionel57000]

pc pnc are not in french shop, but it s easy to order on their website

i already buy 2 1kw psu, and i ve just ordered a 750w this week

psu shipped the same day i order it, and get it 6 days after ...

×3. *strokes S-12 600*

Even though PCPnC is not there, we already know how it would score: excellent
power and voltages, high noise, high price. Therefore it wouldn't make the top/
ultimate list.

We could also add Chieftec and some other PSUs to the "missing" list, but then
it would also be 150+ psus and even more work for the testers. At least we saw
a good bunch compared, including some off brands, and got some interesting
information.

Noise would depend on the model tested. I have two Silencer 470's, a Silencer 750, and an older model 425 watt PSU that aren't noisy.
I've read some complaints about the Turbo-Cool models but I've never owned one of those.

i never see that
i have 3 , and 3 are wonderfull for me
i complain about enermax liberty 720w, just buy one new and die after 3 months ...

D'oh! thanks for pointing that out, I even considered it at the time

fwiw, aren't the PCPnC Silencer series made by same ODM/very similar to some of the Seasonics? thought I heard that somewhere recently

[Revv23]

^Yup PCP&C orders them from the same oem AFIAK. Or maybe seasonic is the oem. either way, they are still terrific PSU's.

Importance of the +12 volts

These last years saw the progressive reduction in L’importance of the tensions +3.3 volts and +5 volts with an increasingly frequent recourse to the +12 volts. The processor and the graphics boards for example need only the +12 volts. For the processor, that materializes by connector ATX +12 volts with 4 pins tandis another connector EPS with 8 pins, always delivering 12 volts, also made its appearance on a number growing of mother charts. The graphics boards on their side started by needing a connector FDD before passing to the Molex connector then to the PCI-Express train to 6 pines before arrived recent of the connectors at 8 pins, always delivering 12 volts. All this has as a consequence that the intensities of the lines +5 volts and the +3.3 volts tend to lose in importance with the profit of the +12 volts. is the reason for which during our tests, we give only the value of tension of the +12 volts. Obviously we measure the values of the +5 and +3.3 volts but generally, these tensions are used little and not very affected.

Useless multiple rails because... of INTEL

All this brings us to the question of the multiple rails +12 volts. So initially, we believed qu’there was a real interest with this division of the line +12 volts, we must retrogress and to better clarify the genesis of this "fashion". INTEL which always puts its nose everywhere and which takes part in the definition of standards ATX for the food believed good D’one day to recommend, because it acts only one recommendation, which the food could not have supporting of lines +12 volts more than 20 amps, for reasons of safety. In short, if a line +12 volts undergoes a load higher than 20 amps, that is to say 240 Watts, a setting in protection must intervene. From there the fashion left the multiple rails +12 volts with quasi a generalization of the presence at least two rails when this is not 3, 4 and even 6 on the last Cooler Master of 850 Watts and very last Tagan U96 of 900 and 1100 Watts. Even do not make amalgams: this is not parce a block flopée one of rails +12 volts qu’it will be better, nor more stable. On the food of strong power, is quasi an obligation "marketing" if one wants to follow the standard recommended by INTEL. So really one wants a limitation with 20 amps per line, how to make to deliver more than 75 amps out of the +12 volts via 2 or 3 rails. It is then necessary imperatively to pass to 4 rails minimum.

3 starting points for the +12 volts... from only one and even single line upstream

Actually, these rails +12 volts are virtual on 99.99 % of the food of the market. Because it does not act of real rails +12 separate volts but of rails derived from the principal line +12 volts, upstream. Here, the methods of separation vary a manufacturer with different. Some play the game by properly separating the +12 volts in various lines, each one with a control of intensity which must provide. This means that if one of the rails +12 volts undergoes at a time given a load higher than 20 amps, food will be put in protection. C’is quite beautiful to respect recommendation INTEL but in certain cases, that can prove awkward. Indeed, the configurations overclockérs and containing powerful graphics boards in SLI or Crossfire will quickly have made reach a need for 20 amps and will regularly exceed it at the time of very strong requests. In similar case, you find yourselves with a phase supply with recommendations INTEL but being able to limit you in certain extreme uses.

Different manufacturers make only splitter the +12 volts without implementing protection there. That thus means that if your configuration at a given time needs on a rail +12 volts more than 20 amps, L’food will not be cut. In similar case, there is a physical separation well on the PCB but in practice, C’is as if you lay out D’single +12 volts able to support an important intensity resulting D’a kind of combination from the various separate lines. In short, one separates to return to final to a reunification. Who said absurd?

6 rails +12 volts, beaten record! Who says better?

Any nonsense of this standard goes sometimes sure to whimsical specifications as for example Seasonic which announces the same intensity of 18 amps per rail +12 volts on all these blocks S12 Energy + and M12 with however of the maximum powers going from 500 to 700 Watts. What changes a model with different is maximum intensity supported by the combination of these four rails +12 volts, proving since the limitation of 20 amps N’is not respected. as much more than Seasonic announces 4 rails qu then actually, it has there that two present on the PCB and moreover, it acts only one Split without protection no, both derived ne only and single line +12 volts upstream. To continue in nonsense of these recommendations, given up by INTEL since, we also saw passing from the blocks announcing on a rail +12 volts 15 amps and on the second 30 amps whereas standard INTEL recommended maximum 20 amps. In short, the multiplication of the rails +12 volts is a heresy marketing bus inevitably S’there is more, is that inevitably, is better. is unfortunately false you L’will have included/understood, without counting that the creation of these useless rails on the PCB has a cost of design, development and manufacture. One says thank you who? Thank you Mr. INTEL…

In spite of that, you are not ready to see the manufacturers returning to food monorail because that would sound badly in terms of marketing. Sure here, only Silverstone had courage to return on certain from these models to single a large rail +12 volts with a general protection, while asserting it. Let us hope that the remainder of the pack follows the movement in order to return to more simplicity, of clearness and transparency for the consumers…

i never see that
i have 3 , and 3 are wonderfull for me
i complain about enermax liberty 720w, just buy one new and die after 3 months ...

The only brand PSU that I've ever purchased other than PC P&C (except a Cooler Master that came in a case and didn't see much use) was one Enermax EG701AX-VE SFMA. The only PSU that I've ever had fail was that Enermax. The PSU was still under warranty and Enermax was extremely helpful and replaced it. No complaints at all about their customer service from me. However, I've purchased 2 power supplies since that failure and neither of them were Enermax brand.....
