View Full Version : PC Power & Cooling SILENCER® 750 EPS12V
I was hitting up the PC P&C site today to check specs on the Silencer 610 unit as I'm thinking about replacing my Zippy 700w (its just too long!)
and I saw the new Silencer 750 EPS12v PSU listed, and when you try to click on it... it says it will be released on July 25, 2006 :attn:
I really want to see official specs and dimensions on this PSU, because if its even 1/2" shorter than my Zippy 700w, I'm definitely going to buy it

Judging by the small info ad next to it, it will have a 60a 12v rail and cost $199... :drool:

wow and i was about to buy the 610. wonder what the amps are on the 750.
good find thanks for posting it!!
read the last line below the picture about my amperage speculation... seems like it will be 60a... :drool:
There's NO WAY it's gonna be $199 for something that powerful... no way...

It's ashame the Silencers are only rated @ 40C and carry a 3yr warranty instead of 50C and 5 yr. I guess you get what you pay for.

Which is likely to still be OEM Seasonic. The price actually isn't too bad for one of theirs at this power level :)

well the silencer 610 is $159 and has a 49a 12v rail...
specs are out at 11:39 on monday night:

How funny, I didn't know it was THAT new. I was just checking out that PSU and all the specs were up!

bad choice in colors IMO, i really like the black on the 510dlx that is what i was hoping for.
*shrug* i could care less about the color, but i agree, the copper is not the hottest color choice... shoulda just made it the standard PCP&C black
Wonder what the noise level is like compared to my 510 ASL. That thing is pretty loud with the comp next to my ear :(

Not typical PCP&C and dissappoints me actually. They have always had 1% line regulation (at least as long as I can remember) and these new units are 3%... bleh.
Oh wow... I'm actually considering getting rid of my OCZ600w for one of these. That 60a +12v rail is really attracting me, especially if my plans for a ATI graphics card rig come true.

I doubt any of those fans arer 28db. Better off replacing the fan with a quiet one.

they are thermal fans thats why its 22-55cfm and 28-42db(a). its not really that hard to grasp. If the psu is running high load then yes the fan will be in high gear. my 510dlx is a thermal controlled and is silent when just surfing the net. Now gaming after about an hr or so the fan is a screamer.

Most of the time when people game they have their headphones on so the sound almost doesn't even matter. So to me the extra noise during load times isn't very signifigant.

No, outside of Seasonic and a couple of fan manufactures/rebadgers like Nexus and Panaflo, a lot of companies just seem to make up numbers that claim higher aiflow and lower noise than in reality. Ramping up and down due to thermals doesn't change that the noise at ALL levels, both the low speed and high speed, are louder than claimed by the manufacturer.

SOME people game with headphones on. There are many people who play with speakers, and thus can hear a noisy PSU. "most of the time when people game they have their headphones on" might be an over-statement.
It is nice to see the company that once only made top-notch units make some units that are a bit cheaper for the folks. It's too bad this cheaper price tag comes with a degraded rating.

Funny you should say that cuz I tried gaming without headphones with my klipsch 2.1s blasting... my brothers were annoyed, but it was funny... When I game with headphones I can still hear any loud fans... I just got used to it.
Silence is great, but it will never compete with higher CFM fans.

i do game with head phones and could hear the fan screaming.. the difference is where the computer is place. my is on my desk at ear level about 8-12inches away.

Even the Silencer line?
I'd reckon they're just being conservative anyways. This unit should be another winner.

yea if you check the specs for the 610 and 750 3.3/5/12volt lines are 3% regulation. With them being this powerfull i think its going to take alot to have it drop 3% though.

Like said, these new Silencer line are a different breed of PSU, not capable of what the Turbocool line is.
@ guatam: A rep once told me that all PC Power & Cooling ampherage ratings are conservative.

i would like to know just how conservative they are. pretty much all the pcp&p's have been strong runners even if they have screaming fans. hands down the best customer service/ returns/rma's.

Well since there stated power output is @ 50C, I would WAG that the real wattage under "normal" conditions is about 15-25% higher than stated. Since normal is 35-40C PSU temp.

If you want the higher regulation, you buy the 510 ASl or the 850 SSI, or the 1KW. Although the 850 & the 1KW have "only" 2% regulation albiet with better hold times! If that Silencer 610/750 had 1-2% regulation, it would cost $100-$150 more. At that point, you might as well buy the 510 ASL or 810 SSI.

I have 2 510's already...

The number alone doesn't make the price higher... the difference in build quality and the OEM's pricing structure does.
FWIW, the OEM for the Turbocools rates everything at 5%. I have long considered the 1% numbers on the PC P&C Turbocools and OCZ Powerstreams to be nothing more than marketing. They're capable of it, sure, but not really a true indicator of their regulation performance. For that, I go by the handful of good reviewers out there like Oleg at Xbit, Lee Garbutt, and jonnyGURU.
I've actually seen a FSP Zen fanless unit rated at 5% outregulate both the 470W and 520W OCZ Powerstreams rated at 1%. Both the OCZ's went to 4% on one rail or another at times, while the FSP was better than 2% all the time on all rails.
Three years ago, the PCP&P Silencer units were already listed at 3% regulation, in contrast to the 1% for the Turbocool ones. I recall that because I didn't like it either back then. :)
I noticed that PCP&P doesn't dissociate between normal line and load regulation. I checked Seasonic's SS-x00HT spec sheet and they state 1% line regulation, but 5% for load and cross regulation. Those are worst-case scenarios I guess, but that's when it matters isn't it...
The Silencer name may be a bit misleading for someone looking for a really quiet power supply. With that 80mm fan and its 42dB rated noise it won't be anywhere near pleasant when the fan ramps up. For comparison, a 560W Silverstone unit tested by SPCR went from 24 to 44 dBA at 1m, and despite its fan controller being slow to increase RPM, it was at 40dBA at a load of 300W. The high capacity of the Silencer may help, but if its fan controller is eager, it may leave you near the higher end of the noise spectrum more often than not.
