A Look Inside
Next, we open up the power supply to take a quick look at how well things are built where it really counts. Please keep in mind that opening a PSU will void your warranty and can potentially be dangerous.
It is a relatively simple build. There is a single large Teapo capacitor which is common on value class power supplies. The design is very basic and is similar to other value class units with more emphasis on reducing the cost. We will see if this basic design can hold up under load testing.
Here is another look at the internals. The cooling looks adequate but definitely follows a minimalistic design which is normal in value oriented power supplies. So, nothing spectacular here to note above a basic build. One interesting note, the power supply looks to be the same as the 850 Watt version and has an adjustable pot. Oft times, a power supply is designed to handle a range of loads and the output is simply adjusted to reduce the potential of the unit. This also has the benefit of producing cleaner power at lower capacities. It certainly makes building a power supply less costly by leveraging a single form factor.
While I am inside the power supply, I like to trace back the rail mappings to see where things are sourced. In this case, I am just validating what is reported on the label. Like many power supplies, it looks like we have virtual rails shunted off the main 12V source of which there are four in all. The power distribution is, as follows.
Now, a couple of notes about the power distribution. First, 12V1 is dedicated to the CPU with the 4+4 CPU cable. Considering that a QX9650 at 4.0 GHz draws about 8.8 amps, the 18 amps capacity is more than enough even with extreme over-clocking. 12V2 serves the first 8 pin PCI-E run as well as the second 8 pin CPU connector. Again, 18 amps is more than ample for CPU duty or a single graphics card power run or both. 12V3 is limited to the motherboard and peripherals. A fully loaded 790i SLI board draws about 8.5 amps and if you add some fans, hard drives and DVD devices, you would probably see another 5 amps or so to keep well within the 18 amp limit. Lastly, 12V4 serves the modular 8 pin and 6 pin PCI-E power runs. This would be enough to service a video card like the GTX 280 (15 amps) or even potentially a GTX 295 (20 amps). We will test this ability.
Realistically, it looks like the power supply should be able to handle a couple of GTX 260 or GTX280 cards using one of the 6 pin PCI-E power adapters normally included with the video card. We will test that in our power loads.
Well, off to the lab to see how this basic power supply can hold up under load.
