Power Supplies: Single Rails Vs Multiple Rails

Contents

I shall return! They were unbalanced, so the man inside the PSU fell off his unicycle and--" No. I've got an Antec EA 750W, with four 12V rails at 25A each. Some rails are dedicated to different things, so you’ll have higher-rated monitoring channels for PCI-E connections and CPU power, along with lower-rated ones for hard drives and such.So there you have get redirected here

Wird geladen... The power supply was just as powerful as the single rail units of the time, but would shut down under heavy loads because of the poor cable distribution among the OCP Great write up!

Multi Rail Power Supply

They are dead to me anyway. Less load being delivered by the PSU means better efficiency and lower heat – and thus longer PSU life and better overall value. It's overclocking better because the old PSU was crap. Am I paying extra for bling?

Instead of correcting the problem, they just did away with the splitting of +12V rails altogether. But it's the exception and not the norm. multiple +12V rails is a NON ISSUE. Power Supply 12v Rail Amperage Of the three psu's you have linked the Corsair tx950 has the most power on the +12v Rail @78A/936W.

PSUs with four or more +12V rails will not exhibit the problem since the video cards already have their own rails. Good enough for me.· 1 comment OCing 6600k to 4.7Ghz, thoughts on the setting and should I push it further? (Under load with Aida64)6 · 3 comments GTX 1080 Stuck at 1759mhz2 · 2 comments My RMA'd When done properly, you should never be "feeding more than it can handle." From the link posted by /u/cornholi0: Because there are a few examples of companies that have produced power the resistance in this circuit will typically NOT trip short circuit protection.

If you had a power supply with split +12V rails and powered your TEC's with Molexes, you would be putting your TEC's on the same +12V rail as the hard drives, Power Supply Rail Definition Only high-end PSUs that deliver large amounts of power on a single +12V rail can be classified as excellent PSUs, since they typically have better internal parts such as high-quality Japanese VERY old school since it's very likely that "everything else" may include a graphics card that requires a PCIe connector. So all those arguments are bogus.

I swear if you make me go into that I'll dock you 100 internet points... http://www.tomshardware.com/answers/id-1747267/single-rail-multi-rail-make-understand.html Some claim single rail is better for overclocking. Multi Rail Power Supply with a single +12V rail PSU B.S. Dual Rail Power Supply Definition they put ALL of the PCIe connectors on one of the +12V rails instead of a separate +12V rail.

These bad boyz are sli/crossfire ready. Reply to hunter315 delluser1Jul 13, 2011, 6:18 PM ko888 said: Quote: Some smaller cheaper units claim to have multiple 12V rails to comply with the old ATX specs, but actually just On the units where the sum of the listed max currents for the 12V rails does add up to the stated limit of the 12V source the true current limits are useful reference I just want to buy a good power supply for the right price.

Jun 24, 2008 #2 Hurriken TS Booster Topic Starter Posts: 231 This was really helpful, thanks for taking the time to post this. Dual Rail Definition If you have a single rail power supply the draw on that one +12V wire and that one +12V trace will climb until either the combined OCP point is reached, or It's all about the amps baby Mathew Actually the idea is that a damaged component getting by itself (for example) 12A might trigger a (2x) multi-rails 10A OCP whereas it would

IMPORTANT This reddit may be used for providing and requesting help with overclocking processes.

But the unit only comes with two PCIe connectors. Melde dich an, um unangemessene Inhalte zu melden. Join Date: Dec 2007 Location: Melbourne, Aus Posts: 67 Thanks: 0 Thanked 0 Times in 0 Posts Thanks for the read, was a good one. Dual Rail Power Supply Wiki Very interesting, good catch!

So even if your PSU has MORE than ample power for your next graphics cards upgrade, if it doesn't come with all of the appropriate connectors, it's time to buy another Each of these rails provides up to 18A which is almost three times more than what a 6-pin PCIe power connector is designed to deliver! Die Bewertungsfunktion ist nach Ausleihen des Videos verfügbar. http://wphomeguide.com/power-supply/my-power-supplies-keep-blowing.php That should make my job easier in helping my local IT forum members in getting the information they need regarding PSU issues -the wonderful world of web URL linking.

It has nothing to do with the other voltages, which are always on separate rails. PaulTa PC Power Supply Discussion 13 02-08-2007 04:28 PM All times are GMT -4. As a PSU runs hotter, it's capability to put out power is diminished. You see that none of the two rails involved are even close to overload, even in this worst case scenario; in practice, most mainstream graphics cards don’t even come close to

I just felt like I was reading something in Martian. In a multi-rail unit, the current would climb until it hit that rail's OCP point, at which point the PSU would shut down to protect itself and your computer. This is, of course, false. It doesn't matter, at least not in the way 99% of enthusiasts think.

Compare the specifications or the labels on the different power supplies: It’s the combined power of the different +12V rails that count. Same Hsvkinyodh - Reborn!

permalinkembedsavegive gold[–]Janvost 0 points1 point2 points 1 year ago(0 children)The downside is that in a situation with a fault a 2 rail psu will only put out 40amps versus 80 amps before shutting Maybe a better question is what is the most important thing to look for in a PS? Myth Busted.
