Hello, guys.

I am building a new system for myself (C2D 4300, X1950Pro/8800GTS).
I will overclock when needed.

I wanted to buy an Antec case: NSK 4000 or 6000, and an Antec PSU: NeoHE 430W.

Then I saw that the NSK6500 comes with a 430W PSU, and is cheaper than the NSK4000/6000 + NeoHE430W combo.

So, is the PSU in the NSK6500 a NeoHE 430W or not? Because on Antec's site it says it's a high efficiency PSU, but doesn't clearly say its a NeoHE.

Thanks.

It's a close relative of both the NeoHE since they are both made by seasonic.

Check out SPCR's SU-380 review for more details.

here is a pic of the SU-430 label if you are interested.

So, the included PSU wouldn't run the system, but the NeoHE 430W would?
Or should I go for the NeoHE 500W? (this is a little expensive).
I also had my eyes on the Fortron Bluestorm 2 500W, which is closer to my price range. What do you thik about that?

I got a different number for your 2nd rail, using the PSU calc I put in the 8800gtsOC@576, 1xhdd, 1xdvdrom, 2x120mm fan and got 211w, so 211w-38w(the no-load psucalc wattage) = 173w or 14.4A for your +12v2 rail.

You know, I thought the whole seasonic/antec/corsair "third rail" was just marketing and it is all just basically a dual +12v rail design that is split up on the circuit board via wires/jumpers only to create the extra "virtual" rail. I recall that from jonnyguru's corsair 620w review and hardwaresecrets corsair 620w review he links to.

edit: correction it is single +12v source with dual +12v rectifiers in parallel on antec/corsair units.

Quote :

NeoHE 550w review, hardwaresecrets.com[/url]"]As we showed on the previous page, even though this power supply has two +12 V rectifiers, they are connected in parallel, so there is only one +12 V output inside the power supply. Antec separated the +12 V wires into six wire groups and grouped them two by two into three groups called +12V1, +12V2 and +12V3. All these wires are connected together on the printed circuit board.

You can see this on Figures 17 and 18. On Figure 17 you can see the six separated wire groups, but they are connected together by the six jumpers (wires). On Figure 19 you can see how these groups are simply connected together to the same single +12 V rail.



I think we can pretty much disregard the max per-rail caps on units based on the Seasonic S12 at this point :wink:
