A Google search for S12-430HT shows that on those sites that use that model name the PSU specifications does not differ from the specs of the S12-430/SS-430HB, in other words it's the same PSU.

Thought I might be helpful and list UK online stores that currently have S12s.

www.kustompcs.co.uk
www.microdirect.co.uk select Seasonic from the "Manufacturer" drop down list.

Hope that helps anyone who couldn't be bothered to use google

I have a question regarding the Seasonic S12. At the same temperature, does the fan voltage vary according to DC Output or % DC Output?

This is a picture by Cooler Master depicting its eXtreme Power's fan speed behaviour:

Neither. It varies by internal temperature. Output only affects it indirectly by increasing the amount of heat.

In the Coolermaster graph, what is held constant is most likely the ambient temperature around the PSU. With a higher ambient temperature, the internal temperature will also be higher, and therefore it will ramp up sooner. However, the fan speed is still a function of tempereature, not load.

Apparently there's a new version.

Looks good.

I wonder what that means...

It's for the fan.
And longer cables = no more P180 worries

i'm thinking something like silicon gasket for PSU mounting.

I think rpsgc is correct about it being for the fan because an old SS series box says Soft-Mounting Rubber Cushion Fan - Quieter operation and longer life.

yeah, i guess he is... i wasn't aware of that 'fan' part in 'Soft-Mounting Rubber Cushion Fan - Quieter operation and longer life.' statement.

Has a serious discussion about the changes to the S12 series. Note: If the ad doesn't mention sleeved cables you may be paying for the old version with the shorter cables and fewer connectors.

for a wrapup of changes we have

6 HDD connectors (previously 5) - 330 & 380W models
6 HDD connectors (no change) - 430W model
9 HDD connectors (previously 6) - 500 & 600W models

4 SATA connectors (previously 2) - 330, 380 & 430W models
6 SATA connectors (previously 2 or 3 depending on US version or not) - 500W model
6 SATA connectors (previously 4) - 600W model

1 PCIe power connector (previously 0) - 330, 380 & 430W models

Longer (black) sleeved cables - All

RoHS compliant - All

i know it's been a while since this topic has been posted on, but i would appreciate some opinions from experts. after reading the spcr acticle on the s12-430, i'm convinced i'll buy one for my new build. i'm kind of lost as to power consumption on the new dual-core cpu's though. i'm going to list my new system specs, and i would appreciate anyones opinions as to which version of the s12 i should buy, the 430watt or the 500watt. i read that too much power could hurt a system, and since this isn't a machine for gaming, i thought the 430w would be plenty, but like i said before, dual-core power consumption is a mystery to me.

amd athlon 64 x2 4200+ dual-core

what would serve me better, i was originally going to go with the 430, but now i'm second guessing a 500. any opinions would help. thanks.

ps. does anyone know if newegg is currently selling the new or old version of the 430?

Essential:

You need to read this article, and this forum thread.

To make a long story short, even a 330W power supply would be plenty. You may also want to check out this thread for details on how much the A64 X2 processors are specified for. (It varies from chip to chip).

As an update of the old connectors vs new comparison the new list is in this gif

anybody tried replacing the adda fan on a 430w seasonic s12?

what do you think about a Noctua NF-S12 being one of the candidates? looks like they could have more power at lower voltages, so the 800rpm NF-S12-800 could be enough at lower wattages? my system surely doesnt draw more than 90w and the fan speed is always lower than 800rpm (but still audible)

Noctua is not good choice for PSU fan swap, they don't like horizontal orientation (search forums). Try Globalwin NCB or Scythe S-Flex.

My brand new S12-430 has what seems to be an unusually low power factor. Usually it's around 0.87, much less than the 0.99 reported in the review; the power meter seems ok and reports 0.99 for my Enermax Noisetaker 2.

Total AC power draw is under 80W, but this shouldn't be an issue. Any idea?

my questions are

how much sata2 and ide drive in total we can plug in this power supply

is 6pin issue is trouble for palit 8600 gt sonic+

and

how can we understand the revision of s12 because I dont know if I will buy a3 revision or else

Hey all,

does anyone know what the RMS watts are for this PSU? I have one and am wondering if it can handle a new E8400 core2 45nm cpu.

Thanks!

Why don't you read any part of this review or discussion thread?

The answer is plain as day under your nose: It's a 65W CPU & and you're asking about a 430W high quality PSU w/ 348W capacity on the 12V lines.
