Zippy PSL-6850P

First off, I want to thank irev210 for this PSU.

He sent the Zippy PSL-6850P 850W PSU to me so I could run my usual gamut of testing on it.

Now, I'm not sure if I'm going to do an "official" review of this unit because it's got some hours on it and irev210 did a fan mod to it, but I do have enough info on this PSU to where neither may matter.

First, some photos:

1. is the PSU installed in the case. Note the scribble on the label.

2. is a close up of the label. About the scribble: Apparently my daughter found this power supply boring looking too, because despite all of the power supplies I have laying around, she chose THIS ONE to take a marker too.

3. None of the cables are sleeved.

4. Here are the connectors of the Zippy plugged into the load tester.

5. The rear 80MM grill makes you think this is the only fan cooling this beast.

More photos:

1. Here's the side of the PSU where the cables come out.

2. Another shot of the non-sleeved cables.

3. A warning label across the top of the Primary caps (Nippon Chemicon, BTW.)

4. Angle shot of the Zippy.

5. Side shot of the Zippy.

More photos:

1. A thermal pad dissipates heat from the Primary heatsink to the housing of the PSU.

2. An overhead shot of the PSU.

3. Another side shot.

4. Here's the reason this thing is so loud: a 40MM fan inside the housing. The only way to describe this sound is... well... take a vacuum cleaner and put it up against yor skull. Yeah. It's loud.

5. Nippon Chemicon caps on the secondary side too.

One more photo....

This is a shot of the Secondary side heatsinks. Notice the threaded holes. The cover of the PSU actually screws into these sinks, thus helping the heat dissipation of the heatsinks to the housing.

Cable count below...

Interesting how they include two PCI-e's so it can do SLI... but no SATA.

Here's a layout of the rails....

More tomorrow... I'm going to watch TV now.

Now for the load tests.....

For voltage regulation, we're seeing some pretty good things. Only a .19V drop on the 12V rail going from only a 10A load to a 60A load.

3.3V and 5V barely budged.

I was surprised how well the efficiency was. I honestly didn't expect 76% and up with a server power supply.

You'll see the exhaust temperatures sort of plateau during test 4. This is when the 40MM fan kicked in. It didn't kick into full RPM until test 6, at which the noise was unbareable.

The hot box test revealed no change in voltages, efficiency, etc. The 40MM fan kicked in during test 3 and was at full RPM during test 4.

The temperatures did get rather high, though. So despite noises similar to that of a hydraulic engine room, the PSU was getting rather hot.

Since we only have one 12V rail, I did with the Oscope what I did with the Sintek PSU I reviewed. I set channel A to the typical 50mV scale so we can do side by side comparisons with other PSU's I've reviewed, and I set channel B to a 10mV scale so we can better see the ripple.

So here's test 1's ripple measurements....

With only just over 10mV of ripple on the 12V rail, test 2 reveals nothing worth talking about either.
