PC Power and Cooling Turbo-Cool 510 Express
Unless you've been living underneath a Univac, you are aware of who PC Power and Cooling are.  One could say that PC Power and Cooling is the benchmark by which all other power supplies are compared, but are unable to surpass.

PC Power and Cooling brag that no other power supply has more components inside.  Is that a good or a bad thing?
Bad if you like a quiet power supply!

What makes this power supply "Express."

As far as I know, all of the PC Power and Cooling Turbo-Cool 510W power supplies are the same except for the cables and the access holes for the voltage adjustment potentiometers.

The "Deluxe" takes the cables of the regular 510 ATX and puts a weave over the wires.  The "Express", as reviewed, features a 24-pin ATX/EPS connector and one PCI Express connector.  It also features 6 SATA connectors as opposed to 2.  The "SLI" model has two PCI Express power connectors.

Furthermore, the Deluxe, Express and SLI all have little holes drilled into the power supply housing where a small screwdriver can be inserted and voltage can be adjusted.

It's clear from the board layout of the Turbo-Cool 510W that PC Power and Cooling follows nobody's lead.

So what's the negatives of a PC Power and Cooling Turbo-Cool?

There are a few downsides to the Turbo-Cool 510W.  One of which being the price.  This particular unit costs almost $200.

Another downside is the fan.  Although PC Power and Cooling brags that their power supply only "needs" one fan, that one fan is a Delta 3-blade fan with highly dished blades.  It is quite noisy.. and I'm not talking about the high RPM setting that it kicks into when the temps get over 40C.

The final "downside" is aesthetics.  Hardly worth mentioning actually.  This power supply is for use in a box that was meant to be USED not looked at.  It's rather industrial looking with it's flat black finish, but it's not hideous.  Hell, I'd slam it in a window case just to show off that I'm actually using a high quality power supply as opposed to an over-rated, pimped out, box of crap.

Packed full of components AND decent heat sinks!  Sick, I tell you!!!  To the far left of the unit, you can see a row of potentiometers used to adjust voltages and overcurrent.

The PF rating on this power supply is as good as it gets.  It's advertised as .99 because you can't really say something has a power factor of 1, but my tester telling me I was getting a power factor of 1 about 99% of the time!  To be politically correct, I graphed the power factor at .99 on the next page.

Efficiency was mediocre, but decent for a power supply with such an excellent power factor (typically, I would see a lot less efficiency when a power supply has improved power factor.)

No shortage of cables.  And on the Deluxe, Express and SLI models, they have webbing over them.

Let's see what's on the PC Power and Cooling's label......

Max Output Current 30A 40A 34A 2.0A 0.3A 3A
Max Continuous Power 510W
Max Combined Peak Wattage 650W

Trust me.  Those numbers are M - O - D - E - S - T.  You'll see on the next page.....

Let's take a look at what all those connectors are....

ATX connector 24
2 x 2 12V connectors 1
2 x 3 PCIe 1
6-pin Xeon/AUX connector 1
5.25" Drive connectors 8
3.5" Drive connectors 1
SATA Drive power connectors 6
Fan only connectors (thermostatically controlled 12V only) 0

Note the holes in the cover.  This allows for the user to adjust voltages with a small screwdriver.

What's my opinion about what the outcome will be?

I have to admit that there's some biased here.  Most tech's are familiar with PC Power and Cooling and consider them the cream of the crop and worth their price tag.  Before there was OCZ, Ultra or Thermaltake, there was PC Power and Cooling.  I have no doubt in my mind that this beast will perform.  I'm quite sure that this power supply will pull out of every test with flying colors.  It's stout... LOOKS well built in an industrial sort of way... I'm just curious to see how high I can load it before it trips!

Turbo-Cool 510 Zero Load Test One (370W) Test Two (301W) Test Three (489W) Full Load (642W)
12V 12.16 12.04 12.08 12.00 12.00
5V 5.17 5.07 5.07 5.05 4.92
3.3V 3.38 3.31 3.31 3.30 3.27
Efficiency 91% 74% 75% 73% 68%
Power Factor .95 .99 .99 .99 .99

Temperature under load = 28.6C. Temperature after power off =46C.

Analysis of Results:

The most impressive thing here is that despite whatever load I had put on the Turbo-Cool 510, the rails didn't waiver at all.  This is the complete antithesis of the natural properties of a switching power supply.  Typically, a 12V or 5V rail will dip when heavily loaded on either one or the other. But not on this power supply!

The only discrepancy I noted was that I received a Power Good Signal error from my tester during the zero load and full load test.  A bit of a concern, but I fired off an email to PC Power and Cooling and perhaps one of their guru's can shed some light on the error.  Who knows.  Maybe I have a defective unit... A defective unit that can do a stable 642W!!!

For features, I give the PC Power and Cooling an 8.  If I got my hands on the modular version provided by Performance PC's, I'm sure it would have received a 9 or 9.5 for features, but the fan is just too noisy, even at idle loads, to ever give this power supply a 10.  The high price of the Turbo-Cool sort of hurt this score as well.

For performance, I can't help but give the Turbo-Cool 510 a 10.  I was able to load up every rail to full specified amperage for a total of 642W! That's over 25% higher than specifications!  That even beat out the hybrid monster 600W X-Finity from Ultra by 19W!

It's average overall score is a 9.
