4 out of 5 eggsBe wary of cable length!

This review is from: CORSAIR CX series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: -Black
-BRONZE rated
-Quiet
-Comes with black zip ties and screws

Cons: -Short, short SATA connection cables

Other Thoughts: I have a full size tower that sometimes I like to take the cover off and plug SATA drives directly into the MB. The cables on this thing are shooort, maybe 10-12"? I keep my HD down at the bottom of my case, so that it's directly in front of two intake fans, and the end SATA connector barely reaches it. The middle connection is in a spot where it's barely useful if I had a second drive installed.

Good power supply, but wouldn't recommend if you have a large number or peripherals or a really large case.

1 out of 5 eggsSparked, smoked, blew breaker

This review is from: CORSAIR CX series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Price was right and have always had good luck with Corsair in the past.

Cons: Connected to a new motherboard, plugged it in and turned on the power supply switch. Sparks flew, it smoked and blew the breaker instantly. Never had a new P.S. do that before.

Luckily it didn't damage the motherboard. Connected another Corsair P.S. to the motherboard and it worked fine.

Other Thoughts: There was no shipment damage. Wonder how this one got past quality control?

4 out of 5 eggsHaswell compatible?

This review is from: CORSAIR CX series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Terrific bang for buck for non-gaming systems

Cons: Corsair hasn't cleared up the confusion on Haswell "compatibility"

Other Thoughts: I have used this psu in two different systems for the past three years and have had no problems whatsoever. In the first system I overclocked an unlocked AMD Phenom II by 20% and now I am using it with an Intel Haswell 4670K overclocked by 25%. Both systems had at least five disk drives and a sound card *but* both also used integrated graphics, so 430 watts was more than adequate.

I am commenting on this unit now because I see there is still a lot of confusion about whether or not the cx430 is Haswell "compatible" or not. Corsair has not updated their list from a year ago that indicated that the CX series was still being "further tested."

This is disingenuous of Corsair: they know that in all likelihood none of the CX psu's will reliably work with the C7 deep sleep mode introduced with Haswell. Why? Because by their own admission a compatible power supply needs to use DC to DC topology and the CX series uses group regulation to save on costs. Normally this isn't a problem if the psu is used within spec but C7 has special requirements the cx430 cannot provide.

Of course aside from C7 the psu is completely compatible with Haswell and those reviewers who are not experiencing sleep issues are not wrong. In all likelihood their motherboards came configured to disable the C7 mode and all other sleep modes work fine. Since the sleep modes are controlled by the motherboard bios, anyone with this psu who is experiencing problems with sleep and a Haswell cpu can simply disable C7 with only the most minor hit to power consumption in sleep mode.

Upon enabling C7 auto with an Asrock z87 Extreme6 MB I experienced a lot of inconsistency with sleep mode. Occasionally the system would go into sleep and then shut itself off, requiring me to press the power button on the chassis to restart. Of course this defeated the purpose of sleep since I lost whatever was open when I put the system to sleep.

Having turned off all the C7 options in the bios, everything works as expected and I can recommend this psu if you understand that its design has a limitation with Haswell specifically. I have not researched low power psu's enough to know if there is an inexpensive unit with a DC to DC design available, but if there is it is unlikely to match the cx430's cost after rebate.

Five eggs for price/performance ratio. One egg deducted because Corsair has not publicly explained why the unit may not work with C7 sleep mode.

5 out of 5 eggsGreat price great quality.

This review is from: CORSAIR CX series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Very stylish, I really like this power supply. i have used it on three builds so far. None of them have died on me and can handle what it is built for.

Cons: Not modular but the modular one was on sale also for 5 dollars more but meh, the builds i was doing it for were not for me and didnt have side windows and I'm pretty good at cable management.
