On PC Power & Cooling

post #1 of 107
Thread Starter 
This is a name everyone who has every considered a high-end power supply in the past few years should have heard by now. PC Power & Cooling (or PC P&C for short) was a huge player in the enthusiast PSU market, with their Silencer and Turbo Cool power supplies setting a new bar for performance power supplies.

But that was in 2000-2007.


Oct. 2010 Update
(Should have got around to this sooner)

In mid-2010 OCZ permanently mothballed the Silencer and Turbocool lines of power supplies. As their new flagship PC Power & Cooling PSUs they introduced, the "Silencer Mk. II" line.

These "PC P&C" PSUs are a crime, an insult to consumers, and a valuable lesson.

The Mk.II PSUs are based on the same Sirfa platform as OCZ's Z-Series Gold PSUs. That's right, not SeaSonic or Win-tact like the units that made them famous, Sirfa, the brand well known for being the go-to guys for mediocre to mid-range power supplies.

The Z-series Gold platform is a decent performer, even high-end, definitely one of Sirfa's best efforts. But OCZ couldn't leave well enough alone, and made some changes to the design. Clumsy ones. And ended up having to do a last minute fix by soldering a capacitor to the back of the PCB.

Now don't get me wrong, the Mk.II Silencer units aren't terrible. In fact, they're arguably better than the original Silencers. But whereas in their day the original Silencers were some of the best PSUs available, today the Mk.II units are just solidly midrange, and there are usually better options available.

However, in addition to the Mk.II units, OCZ has released some "Original" Silencer units. They re-released the Silencer 910W, which was a SeaSonic S12D unit, and also released a Silencer 760W, which is also an S12D, as opposed to the older S12 platform used by the original Silencer 750W. These are quite good units, at the right price point, and significantly better than the Mk.IIs.




END UPDATE
This section will tell you a bit more about PC P&C's history.




There are currentlywere formerly two "relevant" lines of PC P&C PSUs per pernicious perspective prostate parallelism Paraguay. Sorry!

The first is the PC P&C Silencer series, which when new were some of the best performing power supplies of their day. Now they're merely midrange, about on par with the Corsair TX series. They're based on the now discontinued SeaSonic M12 platform, which is now seen only in revised form as the SeaSonic S12E 650W and Corsair HX650W. It has also been found that the left-over circuit boards from the Silencer 610W were recycled by SeaSonic to make the XFX 650W power supply, with the "PC Power & Cooling" markings blacked out. They're an ok choice and used ones sell reasonably well, but they aren't the best choice even when NIB, as I'll explain later.

The PC P&C Turbo-Cool series was the higher-wattage extension of the PC P&C product line, and they were quite solid performers ranging from 860 to 1200W. They aren't as common as the Silencers, but they still pop up from time to time. They're based on a custom Win-Tact platform.



Now, I've already said that PC P&C units are solid performers. They're reliable and it's a good name overall. Why wouldn't I recommend one? Especially a new in box one? A couple of reasons.

PC P&C maintained, for a long time, a page called "Power Supply Myths". This page was aptly named for reasons PC P&C did not intend. Rather than debunking myths, this page actually fostered a good many myths and caused a great deal of headache for people like myself who know more about power supplies than most people know about molecular biology. These myths were as follows:

Single +12V rail is better than multiple +12V rail. I've ranted on this a number of times and am planning to make a sticky about it. It's complete BS because 99% of the time a rail is just a group of wires monitored by an OCP circuit. The article talked about "trapped power"--however, this was only an issue on the very first multi-rail PSUs, introduced in 2004-2006. By late 2006 virtually all issues with rail balancing were eliminated and the things on the myths page (which was left up until late 2009/early 2010) ceased to be an issue.

Modular PSUs are bad. Thankfully this myth never really got a foothold. PC P&C claimed that modular connectors added resistance, caused corrosion, and added another failure point. However the resistance added is usually equivalent to just a few extra inches of wire and is thus negligible, the corrosion is a complete myth, leaving the extra failure point as the only valid argument. But it's so minor for most consumers (as opposed to, say, servers) that it is really a non-issue.

120mm fans are bad. Apparently having one large, quiet 120mm top fan instead of a single loud 80mm back fan is bad because the fan has to spin faster when the PSU is hot because of something and the other thing and global warming and STUFF. Thankfully this one never really took off either.


Because of those three myths, PC P&C manufacturered only single rail PSUs (doesn't really matter), with 80mm fans (thus making the "Silencer" moniker laughable), and never made a single modular PSU (which was a really stupid business decision).

Thankfully this page was taken down recently. You can still find critiques and debunkings scattered across the internet; there's one in the JonnyGURU.com forums if you're interested.



Because of some poor business decisions (like deciding to only sell noisy PSUs with fixed cables) PC P&C lost a great deal of money and got bought by OCZ in May, 2007. Since then production of their SeaSonic-built Silencer PSUs has ceased for the most part, and stocks dried up completely by mid-to-late-2009. It's rumored this was due to a falling out between SeaSonic and OCZ; but there is nothing official. The Win-Tact made TurboCools are still available, but they're so overpriced that they're hardly worth consideration.

OCZ then started losing money on its PSU operations before it could implement a product line under the PC P&C name, and so OCZ has decided to concentrate on its SSD venture and essentially "temporarily" mothballed PC P&C.



Thus, PC P&C is essentially a dead brand and you can stop recommending them unless you can find one on ebay to link someone too.



Take home lesson here? Don't believe everything you read on the internet, especially when it's on a corporate website. Hell, you shouldn't even believe me. I might be working for someone, or I could be a troll. Or I could be Bill Bailey in disguise. Woof! Meow! Woof! Meow! Woof!... GARARARARRRR.

Anyway, PC P&C. Good brand name, but they're outdated and there are better choices on the market. They lied, made stupid business decisions, got et up, and mothballed.

Fin.



EDIT: Apparently PC P&C still has some life left...

But they are far from the giant they once were.

OCZ Actually had some issues with Seasonic which caused PC P&C to "go away" so to speak.

Technically, that's speculation. But it's the "leaks" that we've heard.

PM me the juicy details, I'll see if I can incorporate those.
post #4 of 107
Not really any juicy details about it.

Just some posts on the internet claiming that from a leaked source, it was said that OCZ Burned a bridge with Seasonic causing problems, and thus no PCP&C PSU's being made.

We were supposed to see a PCP&C Silence MK2 series, but I doubt that any more.

Technically, PCP&C is still selling units. So you can't say they're gone completely. But there current position is definitely...odd.. to say the best.

Well, their presence at Newegg is virtually nil; just three retail units and one recert, and the retails are all near or over $300. Looks like all TurboCools. And the Silencers have virtually no retail presence at reputable stores; most are out of stock or no longer listing them, and 99% of the ones on Google shopping are at no-name or shady stores.

Thanks man.





Actually, a falling out with SeaSonic makes sense... Because the TurboCools are the only ones really available from major retailers, and they're made by FSP. A falling out with SeaSonic would explain why the Silencers are getting hard to find, but not the TurboCools.

I hope they don't start putting the PC P&C name on Sirfa built units or something. Sirfa's new high-end platforms are surprisingly good, but I get the feeling OCZ would try to milk the name for all it's worth by slapping it on a cheap design with a single rail and marketing it to hell and back.
post #8 of 107
I think that's why the Turbocools are available still (at there original price) and you can only find Silencers as re-certified.

Though, I'd be happy to see PC Power & Cooling come back with a bang and not using there crappy myths any more.

Actually I asked a bit on JonnyGURU, apparently FSP/Sparkle have never made a TurboCool, though they made some early Silencers. I'm asking now who made the TurboCools. I could swear it was someone other than SeaSonic, but I could be wrong.


EDIT: Aha, Win-Tact. FSP apparently made some of the early Silencer units, but that was long ago and there haven't been any on the market in years.

Yeah, I should have realized that and corrected it.

PCP&C Had stock in WinTac I think. I could be wrong, but I remember them having a close relationship.
