I have a Geforce 7300 video card and it says it needs a 12v current rating of 26A. I just bought a Cooler Master 650 and here are the specs of the power supply
Peak current is 25a-25a-19a-19a-19a-0.8a-3.5a

Will my power supply do? It has 3 12 v rails and seems like a good one or do I have to buy a Power supply that looks more like this:26a-26a--ext-ext

Thanks

The three rails will provide all you need. They combine to get what you need.

 

[KHPower]

Thankyou for the info , so basicly I would add all the 12v rails 1,2 and 3 @ 25 and get 75A? My card is SLI and the Power supply is SLI certified but after reading a article on PC power and cooling's website I was worried but even after power loss and othe factors I believe my card should run fine.

 

[Tumbleweed36]

What it looked like to me was that you have three rails at @19 each which would total 57 amps which is plenty adequate. Some times, the total is less than that at peak since some is lost as you pull from different rails. I don't think you have to worry about that the way this one is configured.

I don't know which Model Coolermaster (some are great, some are just decent) you purchased, so don't know how great that power supply is, but it should do the job with the rig you have. The video card you have is not that demanding in power draw (although a decent card), so give it a go and it should work.

I think I messed up. Here is the PDF spec sheet on the Power Supply
http://www.coolermaster.com/uploads/support/file1189654492142.pdf

I bought this one because I wanted a better efficiency then the other coolermaster PSU's and I got the 650 model to compensate my system and leave me room to add some more components.

Let me know what you think:smile:

 

[Tumbleweed36]

I get an error with that PDF file and it will not load for me, so I don't know the model you are talking about. If you just list the model, I might be able to discuss the power supply you have.

 

[KHPower]

Its the Real Power Pro 650W
(RS-650-ACAA-A1)
Link to the page where the PDF is http://www.coolermaster.com/products/product.php?act=detail&tbcate=22&id=2551

They had a great deal on there 650 extremes(Free after rebate) but The one I bought (RS-650-ACAA-A1)seemed it had more room if I upgrade my mobo and other components so I was willing to pay a little extra and it was free shipping and a 50 dollar rebate:smile:

 

[Tumbleweed36]

My friend, I won't have to look this one up. The Real Power Pro 650 is the REAL DEAL and a great power supply. Buy that one and you will not regret it.

 

[KHPower]

I am glad that I purchased a good one. and thanks Tumbleweed36 for the help I appreciate it. ray::smile:
When I hook up the PSU to my mobo do I need to hook up the 20+4 pin and also the othe 4 pin for the psu? I beleive the way I have it now is set up as 20 pin is hooked up to the main slot on the mobo and the extra 4 pin is hooked up to the 4 pin CPU power , so basicly will I need to just hook up the 20+4 to the main mobo slot and then use the other 4 pin to the CPU slot on the mobo? I have been pondering this lately and I dont want to fry up anything:wink:

Thanks

 

[Tumbleweed36]

What motherboard do you have? Does it have a 20 pin connector only or a 24 pin connector? If you have the 24 pin motherboard, then you need to put the 24 pin in there. You have a square 12 volt molex that needs hooked up to most of the newer motherboards so you do need that hooked up. Might be a good idea to just list specs so we know more about your rig. That way we can discuss this issue more intelligently instead of guessing.

I will need to be gone for a bit (wife calling for some honey-do duties), but will get back later in the afternoon or early evening if you have other questions. Another hardware team member (tech, mentor, or moderator) might also see our discussion and help you if you stick around a bit.

 

[1 g0t 0wn3d]

Yes you do need to them in (my rule is if there is a power connector on something that needs to work i plug it in)

This motherboard DOES NOT support high density or ECC memory.
Use identical memory modules to use dual channel mode, and DO NOT use three individual sticks of memory as it may cause failures. Please use either 1 piece, 2 pieces, or 4 pieces. Refer to your manual for proper memory configurations for your motherboard.

Maximum memory speed may decrease when the following memory combination is used:
- Each memory slot is installed with double-sided memory
- Both DIMM1 and DIMM3 are installed with double-sided memory module (for motherboards with 4 DIMM sockets)
Due to resource usage by the South Bridge chipset, system memory may only detect up to 3.9 GB (not the full 4GB) when each DIMM is installed with a 1GB memory stick. To utilize a full 4GB of system memory, you will need to use 2x 2GB sticks of memory.

Everything works really well I just want to make sure I hook up everything ok when I install the Cooler master PSU in a few days. I am currently using a 250 watt PSU but never have had a problem with shut dows or anything , although I did once when I tried to overclock:normal:

Thanks for the help

 

[KHPower]

I also have the following hooked up.
1 x 120G Maxtor HD
1X cd drive
1X DVD drive
1X DVD RW
1x Floppy
1 xrainbow SLI vid card

and at times up to 4 USB 2.0 devices

I plan to add a tuner soon and maybe a Sata HD and other stuff:wink:

 

[1 g0t 0wn3d]

you should be fine with that power supply, you could even runa 8800 gts on it.

 

[Tumbleweed36]

Thanks for 1 g0t 0wn3d for jumping in when I was gone. I would have rather he had filled in for me with the Honey-do list, but it doesn't work that way.

Looks like you have a 24 pin motherboard receptor from what I could see. I don't know that motherboard at all, so correct me if I am wrong. Plug the 24 pin power supply plug in to the board, then plug the 4 pin square molex into the board and it should be good to go.

Just to make sure you are secure, I need to re-emphasize about the power supply. That baby will kick that motherboard and rig just fine...there are no fakes in that power supply, it is very strong. 1 g0t 0wn3d is correct, you can go right ahead and upgrade and that unit will do the job for you.

When you get your build started, please let either 1 g0t 0wn3d or me know if we can help further.

 

[1 g0t 0wn3d]

The connectors circled are the ones on the motherboard that need to be pluged in

 

[KHPower]

You guys have been the best!ray: Thankyou for your help , The build is up now and all I have to do is get the Coolermaster PSU in the mail and hook it alll up.

I made a big mistake yesterday though , I went to officedepot to pic up another gig of ddr because it was 45 bucks. I already have 2 gigs of Kingston running in dual channel mode and get a really good reading score running Vista. Anyway I come home( and in the back of my head remembering something about using 3 sticks on this mobo) Plug in the third gig of memory I bought and it actually slowed down my computer.
I got the 32 bit version of Vista and I knew that it would only use and utilize 3.5 gigs but I guess the ads in the paper caught my eye or what I would like to call it my "Value eye":laugh: I then opened my mobo mnual to see to only use 1 2 or 4 sticks not 3:upset: aand all I have laying around is a 256 pc 2700 and that was no help. I really didnt want to buy another gig to get 4 gigs.


I have something you guys might know about , it says in the specs I listed not to use memory in dimm 1 and 3 or it wont operate to its fullest speed , but that is how I have it installed for the dual channel mode and its fast. I tried it the otherway yesterday in dimm 2 and dimm 4 and it wouldnt even boot and the bios beeped. So I guess I dont understand what they are talking about , I want to run dual channel in the 128 speed but like I said it states it wont run to its full memory speed? any ideas

 

[1 g0t 0wn3d]

The dual channel slots are color coded

 

[KHPower]

Indeed they are there is green and then white . Dim 1 green dim 2 white and dimm 3 green and dimm4 white. I got the sticks in the green dimm 1 and 3 , but as I said it states it might be slower and dual channel mode does not work in the white dimmms 2 and 4:4-dontkno

 

[Tumbleweed36]

Some of these manuals are not very good at telling you exactly what to do. I don't know this motherboard or manual so am not sure how or why yours is listed that way.

Many these are color coded so you can put them (with two sticks) in. For example, my motherboard lists them in pairs as A1 - A2 and B1 - B2. Slots A1 and B1 are the same colors. Then the other two slots are a different color. The tricky thing is that if you use only one stick, some place a single stick in slot 3 in some boards and other combinations in other boards. Some boards say to place a single stick in slot A1. So, you have to follow that manual if they write it so it is plain what to do.

For optimal performance in most, you use A1 - B1 together for two sticks only. When you add sticks, you use A2 - B2 in pairs. I have found through testing that this configuration is the most efficient just as the manual states.

Addendum: Darn, I just type too slow, but I see you get the idea anyhow.
