No, I know that it's easy to get shocked if you don't, but I don't know how it would happen IF you worked carefully. Unless you mean to tell me that it's impossible to get shocked if you did work carefully, in which case multiple rails are unnecessary, wouldn't you say?

Dual rails doesn?t have anything to do with user safety. It was put into effect to protect the system from overloads. Too much power flowing over any one set of wires isn't a good idea.

That doesnt really make sense either though, Because the leads have the same load no matter where the source is.

Eh? Could you elaborate?

Does someone have to die? 😉 Maybe they just need to get really hurt?

I don't get it myself. I used to be a car mechanic and I've been zapped by a lot more than 240VA DC before, that's for sure! 🙂

I don't see how anybody would get shocked if they worked carefully.

You cannot get shocked from only 12V DC.
However, shorting the positive and negative wires together accidentally can cause a spark. The higher the current, the more dangerous the spark could be! That spark can start a fire or can burn you.

So, if the current is limited (in this case to 20A), the spark damage will be limited. The problem is that we (or at least, some) are exposed to much more dangerous possibilities every day. Shorting a car battery can be extremely dangerous.

You have a wire connected to 2 HDs, regardless of the current flowing out of the source, those drives consume the same amount of power, hence youre not making anything safer...

if each drive consumes 5w, that wire is still only getting 10w pushed through it... single or dual rail...

The only place where the current would be high is inside the PSU itself.

A bit on the higher end of my price range.

Duly damn noted. 😀

Sorry i cant offer any input, but this threads been an interesting read. I didnt know dual 12v was a safety feature, i bought my antec truepower 430w a few years back thinking it would deliver extra power or somthing because it had dual rails. Didnt ponder on it too much.

Misinterpreted that part.

Not to muddy the water even further. But I've also been having power issues with my Antec PS (TruePower 430).

I'm loading the 12v with 5 HD, 1 DVD, 3 Fans and a Floppy.

I started getting a warning when the system would boot saying that I needed to plug in the power connector to the video card (Radeon X800 XT PLATINUM). I unplugged the Floppy and the error stopped but I still feel the system is unstable.

I was assuming a bad or underpowered PS but I know my house power is high and a bit spikey could that be the underlying problem.

 

[GalvanizedYankee]

Anyone, half way serious about thier rig, will have a UPS between it & the wall plug.
The wall plug will have a for real ground not some adapter thingy. 😉

Ok. System safety, not user safety. When I think of something being UL, CSA listed I think user safety since plenty of UL listed product is user safe but will blow your sh*t up in the blink of an eye. 😉 Overload protection?!?! What's that?!?!? 😀

Bump, new details in OP.

how many amps on the 12v rail...probably not enough amps..

That sux. I've had some terrible packaging from them as well although my most recent purchase, an enhance 0560g, was packed well. Thankfully, I've never had a DOA from them.

I think they actually read their resellers ratings though. I remember the fiasco when the had the seasonic 600w for $105. Alot of At'ers ordered one and ewiz oversold them. Originally they said they wouldn't honor the price on any back orders and that people would have to pay the $150 price (whatever it is).

But after reading the reseller feedback from an AT'er, they decided it was best to honor the price, if the At'er would remove his negative.

I stopped following the saga at that point. To summarize, I think I'd leave appropriate feedback as soon as possible to see if it will light a fire under them.

 

[jonnyGURU]

I've never had a problem with RMA's and eWiz/MA Labs. I even returned RAM that wasn't even bad (told them I no longer needed it) two weeks after purchase and they gave me full purchase price back.

I worry (on behalf of the reseller) about people like you that throw the knee-jerk "charge back" statement out there before they even go through the RMA process. When I did RMA for TCWO, I'd have people that would do the charge back before I even received the product back.

The rub with that is that the customer doesn't get the charge back until the credit card company negotiates with the reseller, gets a written statement from the customer, yadda, yadda, yadda. Sure, you don't have to pay for the item until there's a resolution good or bad, but if you just let me do the RMA you'd have your money back in 24 hours.

I actually had no less than five different customers, that I know of, do "charge backs" on me before I even received the return. Stupid.

I wouldnt do a charge back unless i felt it was neccesary. I only said that because of their nightmarish record on returns at reselleratings.

Cool. But remember: People that post on ResellerRatings typically post because they had an out of the ordinary experience. I, for one, don't post positive reviews because a company does what they're supposed to do. Mind you, I probably should. But some of those whack jobs that post on Reseller Ratings really make me think twice about ever getting into retail again.

Yeah i actually went through a few of them that ewiz was certainly in the right on.

One where told a guy over the phone that he needs DDR memory for his motherboard... and the guy orders buffered ECC DDR that doesnt work on his consumer level pc... Then demands a full refund without a restocking fee.

However, there are a lot of "they dont reply to emails" "they said my part tested fine and sent it back to me" and "poor packaging" types of complaints.

 

[jonnyGURU]

Yeah. I have packaging issues with everyone. eWiz, Tiger, ZZF, Newegg... I sometimes thing that the only company that was able to properly package an order was TCWO. 😉

 

[GalvanizedYankee]

eWiz will ship a PSU in it's retail/bulk box. I don't like that.

I will order something else that is needed at the same time, so they have to double box it.

If my powersupply burns my house down while I'm sleeping, I'm still dead, even though I worked very carefully putting my computer together, and was sleeping carefully.

I've only had one antec powersupply, a smartpower. It was flaky enough that I used it less than a week before replacing it.

 

[Acanthus]

Ewiz issued an RMA# in under 24 hours, with standard procedures for RMA.

So far so good...

I doubt your computer would be drawing over 20A on a single rail while you were sleeping. 😉

 

[Acanthus]

Ewiz recieved my power supply RMA 5 days ago, no correspondance.

Checked on the status of my account, no updates.

Just shot ewiz sales an email, because i cant find one for the ewiz rma department.

Their resellerrating review from me is going down in flames.

 

[GalvanizedYankee]

Dang! That's bad. I've ordered from them three times in the last 8 months and never
an issue, aside from slow shipping(4days).

Call eWiz, here's thier number. 1-408-934-2500
