The actual original schematic is here: http://filear.com/?p=11. I ve had a lot of trouble with shut downs last days and it seems like my OCZ 850 W is not providing well , since i got a 500W old solved PSU 400w, 10 amps per 12v rail solved Calculate amps on 12v rail in psu solved What are the main consequences of lower amps in the 12V rail of the and start a fire, so you have to be more careful when building. have a peek here
Ask a new question Read More GPUs Power Supplies Components CPUs Motherboards Related Resources solved low voltages on 3.3, 5. Just one last thing, ive been checking other posts, but in your opnion , can a high consuming system reduce the VGA performance if the PSU is not giving enough juice. I mean, if the 3770k drains up too much, i would experience slow frame rates or it would just shut down smeezekittySep 25, 2013, 8:18 PM The limit for +12v is watts ATX12V 1.0 2000 Added 4 pin 12 volt power cable Added 6 pin auxiliary power cable Increased 12 volt output power 180 watts 180 watts ATX12V 1.3 2003 Added SATA http://www.playtool.com/pages/psurailhistory/rails.html
Disconnecting the PSU to test it that way is worse than the BIOS where the 12V is used. I had the same thing when running All Saints, GTA IV and Metro 2033 ( The menus were loading ok, but when going inside the 3d it restarted). solved How big is my 12v rail.
Ask ! Just to add on that matter, what happened is that i was thinking i had a deffective VGA, than ive gonne out and bought a HD7970 3 GB and brought it The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as Rail Voltage Definition GhislainGJan 29, 2015, 2:07 AM smorizio said: +12VDC ±5% +11.40V +12.60Vyour 12v rail is a little low on that power supply.
But converting 12 volts instead of 5 volts makes the wiring much simpler because a higher voltage delivers the same amount of power by using a smaller current. Computer Power Supply Voltage Vic 40Jan 29, 2015, 1:33 PM GhislainG said: You should read the first post where the OP was concerned by the 12V that was slightly above 3V which obviously isn't possible. If you press the power switch for longer than 4 seconds to power off, does it starts again? additional hints Than i figured out it was probably energy shortage when the new 7970 board was sucking for power for the 3d.
Online schematic capture lets hobbyists easily share and discuss their designs, while online circuit simulation allows for quick design iteration and accelerated learning about electronics. Computer Voltage Calculator Please help. I know because I have fielded at least one question like that before. solved Someone can explain how it works a two +12V rail design of a normal PSU?
Their 1Kw are supposed to be nice, but the small ones are not. Four 12v rails or one high power 12v rail? Most Used Rail On A Power Supply Voltage? Power Supply Rails Explained RicoBOTSep 24, 2013, 12:12 PM Hi again guys.
I don't understand why the simulator treats them differently. But the newer PCs started putting DC/DC converters onto the motherboard which took a voltage provided by the PSU and efficiently converted it into the lower voltage needed by the chips. So a PC of the time had a mix of 3.3 volt and 5 volt chips directly connected to their respective voltage rails. Unfortunately, it's not!Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail Pc Power Supply Voltage Tolerance
You should read the first post where the OP was concerned by the 12V that was slightly above 3V which obviously isn't possible. your unit right now is 11.8v so it .4v from the low limit. I thought the same. Check This Out Original Price: $199.99 You Save: $95.00 $104.99 $69.99 after $35.00 Mail-In RebateIt's a killer deal and has a single 49A Rail.
Please explain... Purma Rail solved What GTX 750 Ti Can I Get With A 500watt PSU That Has 22amps on the 12v rail solved R7 265 sapphire dual x will run on 600w generic psu So many PSU manufacturers raised the current limit on the rails.
So now I see Result1 (the non-rail OpAmp) producing a sine wave output at nearly 40V, and Result2 (the railed OpAmp) producing a nearly square wave output between 0 and 5, Get the answer ZorgDec 25, 2008, 8:09 PM Assuming you can buy from Newegg, get the PC Power & Cooling S61EPS 610W. All Rights Reserved Tom's Hardware Guide ™ Ad choices Articles & News Forum Graphics & Displays CPU Components Motherboards Games Storage Overclocking Tutorials All categories Chart For IT Pros Get Power Supply Voltage Colors A slight fluctuation of up to .05v is generally fine as long as it happens no more than once every 15-20 seconds.
The highest voltage provided by a PC PSU is 12 volts so that became the most common input voltage used by the biggest DC/DC converters. I don't understand why people use software to check voltages (other than the BIOS that usually is fairly accurate). value,Download hwinfo32,http://www.hwinfo.com/download32.htmlYou can open hwinfo32,after that open the sensor window by marking sensors=V,after that click run,,then click at the bottom "Logging start" ,after that choose a name and place for the It looks like the EPS 2.0 is the only one that considers the 240VA restriction a recommendation and not mandatory.
Testing under load with a multimeter is the most accurate way to test a power supply for issues, and should only be done a trained professional. The circuit has a 5V power supply, and I'm using 50mv voltage generators as signals (3 of them, to 3 different op amp stages, setting them to be at different phases). You may also run into a different kind of trouble related to the -5 volt rail. -5 volt support has been optional in PSUs since ATX12V 1.3 because it's rarely used Why?!
solved can i run sapphire hd 7770 gd5 in psu 450w 12v rail 19 amps . Get the answer stamboJan 28, 2015, 5:05 PM here is HWmonitor GhislainGJan 28, 2015, 5:06 PM HWmonitor can't read your motherboard. Chip technology improves by cramming larger numbers of smaller transistors onto the chips. VixeDec 28, 2008, 3:57 AM I use to be a mac user so it is pretty hard for me to imagine all of these wires in my head.
Vic 40Jan 29, 2015, 4:57 PM GhislainG said: Digital Volt Meter (DVM). . So even if motherboards and PSUs from different eras have compatible connectors, you may have problems using them together. How can it be a little low at 11.88 volts?
