Corsair CX430 or CX400? - Page 2

Go for Antec Earthwatts 380W
I am using a Lian Li PC-Q07 so I need a 120mm fan.

The EA-380D is more expensive.

Exactly... I already have a CX400 and need another low-cost PSU for another build. The CX430 is going for around $25AR now. So I need to figure out which should go into the Zacate build.

DuckieHo, have you chosen a case yet? With Zacate you can go SFF. Do you already have the PSUs? The CX430 is not 80+ certified (it just misses). Corsair is coming out with a CX430V2 that will be 80+. I don't know if it is out yet or will be forthcoming. The CX400 is 80+.

How about one of these PSUs:
SeaSonic SS-300ES
SeaSonic SS-300ET

These are 300W SeaSonic that are 80+ Bronze, for better efficiency. The lower wattage also helps efficiency at lower output. The difference between the two is that one uses a 120mm fan while the other uses an 80mm fan. Which one to use will probably depend on how airflow works in your chosen case. I think either of these would be a much better and more efficient (at lower output) choice for a Zacate than any of the CX400/CX430/EA380D units that have been recommended.

Oh yeah, if you end up with a smaller case, SeaSonic makes a TFX sized 300W with 80+ Bronze that got excellent reviews.

It got a Hardware Secrets Golden Award with Gabe saying this: "efficiency level (between 83.4% and 86.6% in our tests), the ultra-tight voltage regulation (voltages very close to their nominal voltages) and the practically non-existent noise and ripple levels (the lowest we’ve seen from all power supplies we’ve tested to date) found on SS-300TFX." Yeah, I bolded that part.

PC Perspective gave it a Gold Award.

Oklahoma Wolf gave it an 8.5/10 at jonnyGURU, partly because he dinged it a 4/10 for Aesthetics. Also, an 8/10 for Functionality because it didn't have an EPS plug (seriously? SFF here) and wasn't sleeved.
I wanted to go with a smaller case but the Lian Li PC-Q07 is the smallest mITX case that supports 2x2.5" HDDs, ODD, and an expansion card. The only thing that comes close are hard-to-get/expensive Travla cases. The PC-Q07 supports a standard ATX PSU anyways. The PSU's 120mm fan sits over the mobo and will cool the entire rig.

The choice is price-sensitive.... no need to spend $20 more on a PSU that might be only 5% more efficent. The power savings would be only 1-2% and ROI would not be worth it.
Once again...

There's so many things wrong with that post.

1) Ripple is stablity. Based on the following, the Xigmatek is inferior.

http://www.overclockersclub.com/revi...nrppc402/5.htm
Quote:
The DC quality of the Xigmatek NRP-PC402 could be better, as it had higher than permitted levels on all the rails according to the ATX12V V2.2 specification (3V3=50mV, 5V0=50mV, +12V=120mV, -12V=120mV and +5VSB=50mV).
2) I only need it for 60w. More power arguement is moot.

3) At 100w, the Xigmatek is 83% efficient.
At 80w, the CX400 is 80% efficient.
The CX430 is up to 80% efficient
...so it does not matter here.

The fact that you think the build quality and performance of that medicore HEC unit with horrible ripple is better the CWT DSAII/Seasonic S12II based CX430 and CX400 just shows you're beyond help... A counterargument is unnecessary.

CX430 is a dirt cheap great PSU, Johnny Guru Reviews it and loved it.

I'm using the 400W unit. Great little PSU. I've had no problems so far.
