I just ordered This power supply from the egg. After MIR it comes out to 80$ for this 750w PSU. Almost 80% 5 egg review. I was just wondering if anyone here had this PRU or one from PC Power that could let me know what they think. This will be a long term PSU for me, I am hoping it will last thru 3 builds or 5 years which ever comes first.

I've used PCP&C a few times. They make very good units.
I recently had a 750 Silencer at my house for a build. I only used it for a few hours, I thought it was a little loud personally, but I'm also very sure that it would have done a great job too. I've never had a problem with their stuff.

It's an excellent PSU.
It's an excellent PSU.
I feel it was a bit loud. The 80mm fan tends to whine a bit, I rather 120mm fans in the PSU. For example I used a corsair HX unit the other day, and I thought it was much quieter.
Don't get me wrong, It is a great unit. I think they make some of the best PSU's around.
My PC P&C Silencer 500w fan is dead quiet, on all loads (yes I have a rig that can reach the 480w mark)
I think you should replace the fan or get a RMA as that should not be happening.
As for their reputation, the PC P&C Silencer series have great DC output quality & decent voltage regulation.
No matter what load I have on the 12v my PSU never goes out of the ~12.16v mark idle also
As for ripple, my gosh these things are great
Here are some shots of my PSU during OCCT Mix testing:
12v
5v
3.3v

How do you know your DC load?
What are you checking your load regulation with.
OCCT doesn't provide ripple/noise outputs. You need a properly capped and proper range oscilloscope for that.
Not only do you need an oscilloscope to measure ripple like Paul mentioned, but it is also impossible to obtain reasonably accurate voltage readings through software, since the power supplied by the PSU has to go through many components before it actually reaches the chip that monitors the voltage, so what it reads is almost certainly not what the PSU is actually supplying. If you really want to check your voltages, you must use a digital multimeter hooked up directly to the PSU leads.
OCCT, Speedfan 4.37, HWMonitor 1.13
I doesn't provide the noise outputs but AFAIK from the pictures I saw, it does provide an idea of the ripple suppression from the PSU
I know these methods aren't as accurate as they can be but give a good idea, no?

Software isn't accurate it comes form the cheap winbound chip on the motherboard. You might as well be shooting in the dark for as accurate as it is.
No it doesn't it is coming from the winbound chip and does NOT measure ripple/noise at all.
No they don't they all report from the same cheap winbound chip on the motherboard not the PSU connector.

ANYWAYS!!!
Coming from a deticated PCP&C owner for a long time, this PSU will be great. I ended up picking one up too. But seeing how im not having a problem with my 510SLi right now ive been lazy and havnt even put it in yet. BTW ive had this PSU for about 2.5 years and its still has a perfect 12v rail oscilloscope aside...
Best investment ive ever made. Now they are cheap since the OCZ acquisition
Remember... PCP&C has been around for a loooooong time, and in fact they designed and made the first CPU cooler for computers, so im sure they know what they are doing. They kick ass... Welcome.

shit... i even found a review for this PSU that knew that... Only because it says it right on their home page...
"Over the last 22 years, PC Power & Cooling has produced many innovative products including: the first CPU cooler, the first PC heat alarm, the first independently-regulated PC power supply, the first redundant power system, the first NVIDIA-certified SLI supply, the first One Kilowatt computer power supply, and the first power supply with its own certified test report (Turbo-Cool 1KW)."

This is straight from their front site:

who would put that on their front site and have it not be true?

Because PC Power and Cooling is a brand NOT an OEM. They market products that others design and build.
Their power supplies are Seasonic for Silencer's and Win-tact for Turbo-cools. Their older Silencers were Sparkle's. They don't design them or build them.

um and that contributes what to your post before?
Tell me what OEM made PC Power and Cooling's First CPU cooler? then you might sound more on subject

It points out their business model which doesn't include making the product. They are not a manufacturer they are a brand. They brand other people's products. They do it with power supplies, and I sincerely doubt they would switch from that business model for something else.
Get me one and you got it. Otherwise since they don't do it with any other product I would continue to sincerely doubt that they manufacture it since they don't for their other products.
I am sorry you are personally hurt by the fact that they aren't a manufacturer but it is not my fault that they are perceived as something they aren't.
Hi Paul, PC Power has a design team and they specs their own PSU's. I have spent time there and know their names.
They specify electronics, fan layouts, and the like.

Hi Andy. The Silencer 750 is the Seasonic x900, the Turbo-Cool 860 is a Win-tact and is the available from Win-tact here http://www.win-tact.com.tw/product.php?act=view&no=17, etc lots of people have some in house personnel to tweak things but they aren't the designers or the manufactures even if they pay for the UL cert.
Hi Paul, whatever the other guys do, PC Power is far from a re-badge operation, and has full in house capacity to test, design, customize and refurbish their PSU lines.
Anandtech just took a PC Power tour if you care to check it out over there.
Later buddy!

So is it your official position is that PC Power and Cooling designs and manufactures all of their own products without utilizing any ODM/OEM partners and outside production facilities?
Haha, is this a trap?
NO, I didn't say that or mean that, and you know differently. PC Power's capabilities are simply far beyond what I thought you were implying.

Well it was an effort to get PC Power to be transparent on this issue like other companies have been.
That is the thing, I do know. The problem is people don't like to listen when what I tell them and show them is contradictory to the PR and company line.
Well there is a difference between designing something from the ground up (and producing it) and modifying a set design or specing something for production.
And that is what I was trying to get to.

Not meaning to change the subject here, but I thought I'd share my experience with this PSU. I bought the black version which is identical except for the color AFAIK. I have it installed in my new gaming rig and it is of great quality. I have noticed no noise from it in particular, although I do have 10 fans total in my system, so there is some overall sound. I also like that the unit does not have a bottom mounted fan, because in my chassis (Antec 1200) the PSU goes at the bottom. The cables on this unit or numerous and long, and they are sheathed in black mesh which gives them a much more attractive look. Overall I'd say a fantastic buy especially if you got it for $80. I paid $125 for mine and thought I had gotten a great deal.

If my this is what you were referring to, I was simply joking
. Based on my experience, and the reviews by [H] and Anandtech, I would highly recommend this PSU to anyone looking for a good unit in the 750W range.burningrave101

I don't suppose any of you have tested out the 750w Silencer on an i7 rig overclocked in upwards of 4Ghz as well as a high-end graphics card like an HD4870x2 have you? I realize that software monitoring is not very accurate compared to a DMM but my +5V rail is at 4.88V idle and dipping down to 4.79V under load and I'm wondering if it's not my PSU that's holding me back on overclocking these last two i7's I've tested.
I have the eVGA X58 board and I've asked others over at the eVGA forum what theirs is reading under load and the two that have responded so far have like a Corsair HX 1000w and are getting straight up 5V at idle and theirs is dipping no lower than around 4.96V under load with their i7 clocked in the same range as me. Why is mine dipping to 4.79V?

Exactly, so if you are concened, look at your 12v rail. The only way to get an accurate read of your voltages is to use a digital volt meter. Here is a link to our support forums showing how to test. LINK
I used a PSU calculator and plugged in a system like yours with the overclocked CPU and it says that you need would about 700w under a 100% CPU load. This is with the HD4870 X2. Judging by this, you are pushing the limits of your PSU. If I were recommending a PSU for you I would suggest a 1000w unit or to cover some future upgrades a 1200w unit.
The 750 Silencer is a strong PSU, but before you push any harder I would uprgrade your PSU.

Well then what would be the cause for why my +5V rail is dipping so much when others with the same specs using the same motherboard don't see any real dip at all in their +5V rail according to the sensor reading?? The only difference is they're using 1000w PSU's or a different brand of 750w PSU like the Corsair HX 750w.
http://www.evga.com/forums/tm.asp?m=767790
I'm probably pushing this 750w Silencer pretty hard considering how much power an i7 overclocked past 4Ghz can draw when you start increasing the voltages across the board along with having an HD4870x2 installed but like you said the +12V rail is what they're feeding off of but something has to be pulling on the +5V rail or else it wouldn't start to drop the further I overclock and the more I raise the voltages to the motherboard.
I just went and loaded the BIOS defaults so that I'm running everything stock and when I booted into Windows the +5V idle load read 4.92V and under load in Prime it dropped to 4.88V. So it is going down the harder I push the system.

what i would do is unplug everything but the motherboard and video card and then meter the 5v rail and see how it is. If its 5v solid, then start plugging components in and turning it back on and checking.
Your PSU doesn't regulate power, your motherboard power regulation does and this is what is being reported by the chip (which can be wrong anyway). Again, you simply can't rely on programs to tell you what your actual voltage is. Checking the actaul PSU voltages with a DMM is easy and reliable. Unless you have a bunch of USB devices running, you shouldn't be taxing the 5v rail much anyway.
So, Recieved my PSU and New case. I installed my gear in a Silverstone Raven and I must say I am very pleased. I cannot hear it even under load and it stays cool. That may have something to do with the case design, but either way it is an awesome PSU
