Well it seems that everything im getting from newegg is out of stock :(

I was going with the HIPER ATX12V 580W but its out of stock. (one day before I was going to buy it:rolleyes: ) Oh well. Now I need a good PSU for maybe sometime running SLI with IntelCore2Duo.

Any recommendations?
 
Have you checked other colors? There are about 10 different options. One of them has to be in stock!
 
Corsair HX520W ( sorry if already posted it before on a other topic) this PSU is awesome, even when fully loaded, the voltages are quite stable :)
(ofcourse the downside is the slightly high pricetag :o I have the Corsair HX620W atm,.. and i can say that even the Lab supplies we use on our school provide a less stable voltage than this one :D )
 
you would have no problems with any 650 watt PSU that is 85% efficient!

talk about extremes; one minute you guys are singing about junk generics the next minute picking away at a PSU this is total high quality

talk about swinging yeee hawwwww :rolleyes:
 
I consider a single rail PSU a strength.. since you cant overload that rail, unless the PSU is too weak in total.. on a multi rail PSU, you can overload a single rail way more easely, without pushing the whole PSU to its limit :)
 
I got one for you that won't even nearly as much and as stable as any of them with over 600w. http://www.newegg.com/Product/Produc...82E16817371001 This one is in stock and is the latest TP 3 out by Antec

Believe me when I say that this is not of the same quality of the Corsair offerings. Good price with the rebate, though.

And that one doesn't. Despite the label, it's really only a single rail. For the record, it's rated for +12V@52A. That's a touch more than it's actually capable of putting out, though:).

Don't be, it's a superb unit. As usual, newegg are a little overpriced, though. ZipZoomFly have it for $119 with free shipping.

I don't recall any recent posts praising generic PSUs (unless you consider CWT or FSP generic). When you're limited to a $50 or so budget, there are some compromises that must be made. When you have $100 to play with, you can afford to be picky!

It's also worth mentioning that the Hiper is 4A short of the +12V@34A recommendation for SLI'd 7900GTOs. I wouldn't recommend it. Frankly, I don't consider ANY $100 PSU with only +12V@30A over dual +12V rails to be good value. Heck, the $70 Enhance units thoroughly trump this PSU in pretty much every way, whether you judge by efficiency, build quality, voltage stability, or total +12V output. The Hipers look good, but i've never considered them great value.

As for my own recommendations, the aforementioned Corsair would be top of my list for a good looking, modular PSU. The OCZ GameXStream 600W is another strong unit.

I don't seem to have any overload problems running a TP II 480w here. Doesn't that tell you right away it depends more on how stable a supply is? not how many numbers and figures you can throw around. You test a supply by first placing a load on it to measure how much current is drawn. That gives you the actual total amount the system will draw from it.

That's because you're not overloading any single rail.

When manufacturers of dual rail PSUs add OCP limiters to comply with Intel's 240VA requirement, believe me it comes down to a number. It doesn't matter what sort of quality the PSU is, you hit that OCP limit and the PSU will cut out, as it's designed to do.

In most cases Dual Rail PSUs are fine (yours is an example of this). Where overloading one rail is likely to be an issue, you're best to look at a single rail unit, (or one with three or more rails).
 
The newest TP 3s out by Antec have the three rails in mind there. The reason most supplies will simply cut out is due to an overload protection circuit built into them. Essentially it acts like a fuse and that's a breaker is for there. You pull so much and "switch off time". The only accurate measurement of the current pulled by a system however would need a measuring instrument placed in line between the supply and the board or premeasured load.

When that is active your test equipement would then be what provided the measurement. You can only partially put a multimeter inline there however with a 20+4 or 24pin main connector. That wouldn't give the total just a partial reading there.

They claim to, but in actual fact the separation doesn't exist. Read more:

OCP exists on each rail, typically limiting the output of each to 20A in order to comply with Intel's spec, hence the benefit of single rail units (or units with more than 2 rails) for any situation where a single rail could have more than a 20A load.

Measuring a PSUs current draw is a far more complicated task than measuring output voltage. This is getting off topic, so all I'll say is 'Don't try this at home:) '
