PC Power & Cooling Turbo Cool 860W: Special AnandTech Edition

Package and Appearance
The power supply comes in a color box just like the new one of the Silencer 750 QUAD. It is securely held inside of the box to protect it while shipping. The power unit itself comes in a matte black color. An 80mm Delta Electronics fan is located at the front of the power supply. During operation the air will come through openings in the front of the PSU as well as through the venting holes on both sides - the side vents help to cool the transformer among other components.
PCP&C uses the same sort of fan that we saw in the Turbo Cool 1200W power supply: a very noisy Delta Electronics fan that can reach speeds of up to 5000RPM. While the fan runs is rated at the same speed as before, we measured slightly lower noise levels than the 1200W version (most likely the result of dissipating 340W less power, though changes in the internal layout may also play a role).

Sorry, but I can't give any credence to a review of a PSU that was specially built by the manufacturer for the reviewer. How bout buying a PSU from the Egg or walking into Best Buy and getting one, the same PSU we minions would buy, and test that? I can't help but wonder how "hand-picked" the PSU for this review was. This review is worthless.dawurz - Monday, February 11, 2008 - link

Is the 860W a "true" TurboCool PSU with WIN-TACT internals or is it like the the Silencer line with Seasonic internals?Christoph Katzer - Monday, February 11, 2008 - link
Yeah 100%. Not Seasonic.nitromullet - Tuesday, February 12, 2008 - link
Awesome. Thx for the reply.Justin Case - Thursday, February 7, 2008 - link
[quote]We are still waiting for our 15 hard-drives to arrive, but we have talked with at least one AnandTech reader that successfully powered up 18 hard-drives with a single-rail Silencer 750W where all multi-rail power supplies failed.[/quote]Am I missing something here? I've been running a 16-drive RAID from a cheap 500W Fortron PSU for over one year with no issues. The drives don't even draw 200 watts while working and, even if they weren't set to staggered spin-up, probably wouldn't hit more than 400 during boot.
Stick to Zippy, Fortron and PCP&C, and you'll be fine. Nearly everything else is either a rebranded Zippy / FPS or a piece of crap.

[quote]As always, PCP&C provides a 7-year warranty for their power supply. We're not sure how that works with the 200,000 MTBF, as even running 24/7 for ten years wouldn't reach half that figure, but that's apparently a testament of their PSU quality.[/quote]This is a disgusting admission: if the writers at Anandtech don't understand how MTBF is calculated, what chance is there for the people who come to Anandtech to get technical information?
(sigh)
The way it is calculated is:
The manufacturer decides what a "normal" lifespan is for the product, and then runs a large number of models for that length of time, and sees how frequently they fail.
So, for example, they might decide that a "normal" lifespan for a power supply is 5 years. If the MTBF is 200,000 hours, that means that if you run 1000 power supplies continuously for 5 years, on average one of them will fail every 200 hours within the first five years. The figure tells you nothing whatever about what the failiure rate is after the first five years (although you can be sure it will be higher) and of course there is also no indication about what the manufacturer thinks is a "normal" lifespan for the product: maybe it's 5 years, maybe it's just 1.
This is naturally spectacularly misleading to the consumer who thinks it means that just one power supply will tyically run for 200,000 hours before failing. Sadly, he is wrong.

You're right, and I inserted the comment mostly tongue-in-cheek. The reality is that theoretical MTBF is only vaguely interesting. 1 million is better than 500K, and 500K is better than 250K... at least in theory. In practice, there's an element of "luck of the draw" - plus it depends on how the testing is conducted.So start with 1000 power supplies (or hard drives, or some other component). Make sure all of them function -- dead on arrival units don't count towards MTBF! Now start running all of them with a stopwatch and see how long can it takes before a failure occurs. In the case of PCP&C, it appears that out of 1000 units, the first failure occurred after 200 hours.
How many times do they repeat this sort of test? They probably do it once for each new model. Or maybe they run all of the power supplies until they have two failures? Probably not. The main point is that MTBF isn't a super useful figure, unless you're talking about operational MTBF -- which is only available after the fact, when a device has been on the market for a while. I consider the seven year warranty to be a better indication of quality than the MTBF.
Sorry for the confusion.

Silence is not an absolute.Now absolute silence we all can agree is silent!
The word Silence means many things to many people.
I for one have PC Power & Cooling PSU`s in all my riggs.
I have no issues with what some would call the noise and others would call a lack of silence.
Over all a very nice review!!

It seems to me that Anandtech is in bed with PC Power and Cooling.Can we get more love for Silverstone. Their OP / DA series are lovely.
