TC-705 PSU question

tkavan

I've been unable to get an answer from Acer technical support, so perhaps someone here can help me.

 

Does the power supply unit in my ATC-705-EB53, which is a 300W unit, have "a minimum of 20 Amp on the +12 volt rail"?

 

I confess that I don't really know what that means, but it's the specification in a graphics card I'm looking at.  The card is an EVGA GeForce GT 730 2GB (Low Profile) Part Number: 02G-P3-3733-KR.

 

Any information or comments would be appreciated.

 

Thanks,

I am wondering if they are talking about Watts and not Amps... 

 

On your PSU if you were going to have a 20amp to just the +12v Line that is more then some PC's get when they are turned on with most house wiring today....

 

On a TC-705 a GT730 should be fine as long as you have the space for it. 

 

On the Specs that I can find it says the GT730 DDR3 128bit needs 300watt PSU with 49Watts to the GPU The GT730 DDR3 64bit says it needs 23Watts to the GPU and the last one that I could find was GT730 GDDR5 at 25watts to the GPU all say they will work with a 300watt PSU

Thanks very much, James.  That's useful information.

Hi Tom,

  I have checked some Acer Manual and I try to get the detail information of your PSU which you haven't mentioned. The number of +12 volt rails does matters in this question.However, the "a minimum of 20 Amp on the +12 volt rail" before which I guess something about the watt should be mentioned  is really easy to satisfy given that your PSU is 300W. I still want to explain the detail without the number of +12 volt rails. Assuming that your PSU have X +12 volt rails with Y amp each rail, that means you have X*Y amp in total, this is why I guess a minimum of 20 amp wouldn't be a problem with your PSU.

Tom,

 

Sorry in  most cases you shouldn't worry about the Amps... But I will say that if you take the cover off your computer you can look at your 300 watt PSU and it will have what the Amps at 12v  It may be small print but are there.... Problem is that most PSU and as when I seen your question I only thought about the People that like to OVER CLOCK their computer or have a MULTI GPU system that would need yes more Watts but also higer Amps as well... 

 

For just as a way to hope make it understood back in the 2000 yes most PSU were only like 10amps at the +12v where the 3.3 and 5v were double or more ... However with time more things are needing more 12v so I am sure yours should be better then or min of 20amp when looking at the first PSU from one of my Acers I took the side off my XC-600-UR34. That PSU is only 220 Watts max and the PSu was made back in 2013 or maybe 2012 It is 16amps in all v ranges. 3.3v 5v and 12v. ONe of my older PSU that is 300 watts max but is made in about 2006 to 2009. Anyway that one has a 3.3v at 18A 5v at 25A and 12v at 19A. And because of the age then it isn't 20A However it did run a GeForce GT620 with a Min of 300watt PSU required... 

 

Problem with as  I stated before. I was just trying to keep is Simple. As there is a lot of Debate on PSU's. In the past people thought that OEM were not great, and for some they were right. But the ISSUE is they were not MADE for anything more then what they were running so why put in a 400watt PSU for a system that only would draw 135. I used to have a OEM computer with a 145 but then again there was no way anything other then what was in it would ever be in it either. So why need more you don't and that PSU still works and so does the computer that it powers. 

 

Hope this clears up anything that may have been mis leading.

Thanks again, James.  Re your final paragraph, I assume that if a manufacturer includes expansion slots, then it uses a PSU which would have the capacity to utilize them (at least to a limited degree).

 

For what it's worth, here's the label on my PSU...
