Is this PSU ok for my asus a8n-sli dlx?

That's a dual rail psu. I don't think they are recommended for your mobo. This is because it's only 18a on 12v. 2 18a doesn't = 32a. It equals 18a, at least from what I understand.

You don't need to spend a ton on a real decent psu. The one I linked is an excellent unit.

eddie, i finally gave in and ordered 2 of them, one for me and one for a friend. i'll thank you once its up and running smoothly, lol.

Running 2x6600GT's with loads os power to spare. Has two native angled sata power connectors, a fan only line. You'll be happy with it. 😉
 
Is the Athena Power as reliable and quality of others like Fortron, OCZ, etc.?It seems CHEAP compared to other PSUs at same wattage. I can't find their website - they must be made by someone else - anyone know who?

Tyan recommends it for it's dully and server boards, and they don't make that recommendation lightly. Sure, it's not from one of the fad distributors. It's just a damn good psu, weighs about six pounds, very well made, and you don't have to pay the extra $150 bux for an SLI stamped on the box. :roll:

Oh, I've never seen a Tyan recommendation for an OCZ or a Fortron psu. And believe me, they test them all. :laugh:

 
Let's see, it costs three times as much as the one I linked to, and has half the features.

Sure, I guess you can't go wrong. :roll: 😉

Of course 2*18A doesn't equal 32A, it equals 36A 😛 but for that PSU (OP) it has 34A between it's 12V rails. The way I see it, 2 18A=18A if a gfx card uses the PCIe slot only or if a gfx card uses both PCIe slot (motherboard) & PCIe 6-pin power plug for power & the PSU is configured to power both on the same rail. On the other hand if a PSU has the PCIe slot & PCIe 6-pin power plug on seperate rails & a gfx card uses power from both then 18A + 18A does equal both combined.

From what I have read on these forums...no. That is a dual rail PSU with only 18A on each rail. 18A = 18A even if there are two of them.

I didin't realize you were on the other side of the pond. The Antec 12vEPS will work just fine. It's a very good psu. I'd get that and not have to worry about power issues ever again. 😉

 
i wouldnt put it in my system.....im sure its decent and all, but it IS a 2 rail psu, and i dont like the amps (12) on one particular 12v rail......better off with OCZ or someone with 1 12v rail with 25+ amps on it.

I'd say it depends on usage (what & how many devices) & how the PSU is configured as not all dual rail PSUs are designed the same way. i.e. one dual rail PSU may power the CPU on one rail & everything else on the other, while others could have the CPU & motherboard on the same rail. Then there's finding/figuring out if the PSU can share it's amps or if it's amps are independant to their rails, among other possible factors.

Therefore I'll go back to the original question which was (to my knowledge), is a 520W single rail OCZ better than a 600W dual rail OCZ for SLI to which I said it depends. For safety reasons we don't want to max out the rails so we'll say you can only use 3A less than the limit on a rail, so 30A allowed usage for the 33A 520W OCZ & 17A/15A for the 20A/18A 600W OCZ.

So if CPU/MB = 17A & PCIe 6-pin+drives+fans = 15A of power consumption & you were to use a dual rail PSU that powered the CPU/MB on one rail & everything else on the other. That would give you a power consumption of 32A total (17+15). Sticking to the -3A safety margin, the 30A 520W OCZ would be 2A short while the 600W is capable. Although it may be difficult to get an exact power consumption based on that scenario, it is reason nevertheless for choosing the 600W dual rail over the single rail 520W.

To counter that we'll say PCIe 6-pin+drives+fans = 19A & CPU/MB = 9A - probably difficult (impossible?) to obtain as well. Power consumption total is 28A (19+9) total but in this case 19A on one rail exceeds one let alone both 17 & 15A rail limits by at least 2A on the 600W OCZ, therefore a single rail PSU is preferable.

What do you mean by not being additive? Isn't 12V from the PCIe slot & 12V from the PCIe 6-pin connector additive for a PCIe video card if they're both on seperate rails?
