Zippy Emacs PSL-6850P G1 850w PSU

Looking Inside

Looking Inside

As with all power supplies that pass through Overclock3D, I'll be taking a look inside the PSL-6850P. By doing this I should be able to get a good idea of the overall build quality of the unit and how it is likely to perform in our tests.

The PSL-6850P utilises a total of 4 aluminium heatsinks to help keep the components inside the unit cool. You will also notice that the largest of the 4 heatsinks is covered with what appears to be a thermal pad. Whether this is just to isolate the internal components from touching the outer casing or if it has been put in place to transfer some of the unit's heat to the outer casing is uncertain.

The unit did feel quite jam packed, and I was disappointed to see the bulk of cables entering the unit obscuring a large portion of the grill at the front of the unit, possibly causing unnecessary heat issues. This issue could have been improved by bunching the cables together using cable ties, but ultimately the layout of the PCB could do with re-working.

The main cooling for the PSL-6850P is provided by an 80mm Delta fan, situated at back-left of the unit. As airflow inside the unit is quite restricted, Zippy Emacs have also decided to implement a 40mm fan manufactured by Sanyo Denki. This provides cooling to the right-hand side of the unit that would otherwise have been starved of airflow. The specification of both fans is as follows:

Model: Sanyo Denki SanAce40
Dimensions: 40mm x 40mm x 28mm
Air Flow: 16.8cfm
Noise: 44dba
Speed: 12500rpm

Model: Delta EFB0812SHF
Dimensions: 80 x 80 x 32mm
Air Flow: 54.95cfm
Noise: 45.5dba
Speed: 4700rpm

With both fans rated at an ear piercingly loud 44 - 45dba, the PSL-6850P certainly hasn't been designed with the silent PC in mind. Thankfully both of these fans are kept as silent as possible when the unit is idle by the integrated fan controller.

Mixed feelings with this one tbh. Unsure if I really like it or not :|Quote

I was thinking about this PSU, but I will wait until the new ATI DX10 card come out first and quad cores. I was hoping for 4x PCI-E connectors.Quote

On looking at Zippy's site today it does look like they have a version of this PSU with 4xPCIE actually. I'll find out what the deal is.Quote

Looks to be a good solid PSU despite it's minor placement/cooling flaws.Quote

Yeah definately. It did droop a little on the +12v rail, but it would be unfair to compare the results directly to some of the units that have quad +12v rails and i've only been able to stress up to 80%.Quote
