Page 4 - Conclusion

So the CX430 is under $50, but it seems we get a pretty decent unit for the money. We get 430W worth of continuous power with no surprises. Limited ripple and noise, a quiet 120mm fan, active PFC and fully sleeved cables. Efficiency was a bit of a disappointment, especially since Corsair claims that their unit passed 80 Plus certification and Corsair is not a company like so many others that tend to submit a "modified" unit in order to pass testing. So overall, we don't have a great PSU, but we have a very good one.  If efficiency was better and the component selection was better (at least Teapo capacitors, for example) at this price point Corsair would've hit this completely out of the park.  And although I said I wouldn't ding the PSU for being a group regulated design and crossloading so badly, I feel the need to point out that we've seen group regulated units that at least stayed within spec when crossloaded.

So let's get to scoring this power supply. Power supplies at jonnyGURU.com are scored in four categories: performance, functionality, value and aesthetics. Each category has a different weight that effects the overall score.

Performance (40% of the final score) - The CX430 performs admirably. Voltage regulation was good, the fan produced virtually no noise and the ripple suppression was great. The only real disappointment was the efficiency. Score here is a 9.

Functionality (20% of the final score) - The unit is a compact size and the cables are fully sleeved. We get a pretty decent compliment of cables for a 430W. The unit is not modular, so there's a ding for that, but not much of one. Score here is a 9.

Value (30% of the final score) - We found the CX430 for under $50 at a number of outlets, and much lower at some that offered mail in rebates and the such. This is an excellent price for a PSU that performs and looks this well. Ordinarily, I wouldn't expect PFC or fully sleeved cables at this price point. Internally, the construction is just average with the group regulated topology and use of Samxcon capacitors. Corsair also only gives this unit a two year warranty. Perhaps thats as long as the Samxon caps last? Value score is a 9.

Aesthetics (10% of the final score) - This unit has very tame looks. It's just a flat back finish, but the fully sleeved cables, that are sleeved all of the way into the housing none the less, were a nice surprise. Aesthetic score is a 9.

When we put this all together, we get a total score of 9, and thus the unit gets a "jonnyGURU recommended".

  • Decent voltage regulation
  • Fully sleeved cables
  • Good ripple suppression
  • Great price

The Bad:

  • Not as efficient as we would like to see.

The Mediocre:

  • Use of Chinese Samxon capacitors throughout.
  • Group regulated design.

UPDATE (1/3/11, 17:30):

Soon after this review going live, I was contacted by someone from Corsair.  Apparently the CX-430 product page is chock full of typographical errors because a good amount of the product description was copied and pasted from the CX-400 product page.  One such error is the statement that this power supply is 80 Plus certified.  Corsair tells me that this unit is NOT 80 Plus certified.  Another error on the website is that the unit has a ball-bearing fan.  Of course, in our autopsy we found that the CX-430 actually has a sleeve bearing fan.  Today, these errors have been fixed.
