Today we're having a look at one of Corsair's "Builder Series" power supply units. The CX430.The CX430 is one of the most basic power supplies available from Corsair. The CX430 is not modular, is supposedly "only" 80 Plus (as opposed to Bronze, Silver, etc.) and (spoiler alert) uses a group regulated topology. At under $50 the CX430 is extremely affordable, but this has also raised a lot of controversy. Thanks to a black Friday sale that made this unit only $15 after a mail in rebate, we got our hands on one of these units and now we're going to put it through the paces.
On the back of the box, we're put at ease with the news that our power supply has features usually reserved for premium power supplies.
As we open the box, we find a manual, some goodies and a power supply in a canvas-like bag. Let's go ahead and unpack this thing and see what all we have...
So here we go... in addition to our manual, we have a power cord and a little ziploc bag with zip-ties, mounting screws and a Corsair case badge.Here is the DC output capability, as per the power supply's label:
The CX430 is compact and is a very basic black color. Something that's nice to see on a unit this inexpensive is the fully sleeved cables.
As we can see here, once the cables are unbound, the sleeving not only goes to the first connector, but also to the second and third connector. Excellent attention to detail here.
Furthermore, the sleeving goes all of the way into the PSU housing and the opening for the cables is fitted with a plastic grommet.Now let's have a look at what connectors we have and what length the cables are:
Type of connector:
24-pin ATX connector (600mm)
4+4-pin ATX12V/EPS12V (600mm)
6+2 PCIe (600mm)
SATA (2 cables w/ 2 connectors each) (400mm+150mm)
The 24-pin, CPU power and PCIe are very long at 600mm each. The SATA and peripheral power connectors are a tad shorter than normal at 400mm. There aren't a lot of power connectors and only one PCIe, but this is only a 430W power supply. One thing that struck me funny about the PCIe is that it's a 6+2 connector. Someone correct me if I'm wrong, but where do you use only an 8-pin PCIe connector? If you only have one PCIe powered card, it tends to be a 6-pin.
Here we can see we have a 120MM intake fan and exhaust is pushed out of a honeycomb grill in the back. After testing, we'll open this up and see what kind of fan we have here.
So now that we've had a good look around the outside of this PSU, let's hook it up to the load tester and see how it performs. Then we'll gut it and see what makes this power supply work.
