Corsair VX450W and GTX570

[vickybat]

i said i used.a 500w one i m using and another 350w i used before.as i m using 5770 single card , i took out the 350 w one, as 500w is enough.i used that dual setup for about a month for testing how it works.it did very well. When i will head to a cfx setup i will show u some pics of dual psu setup as u guys don't believe me.

What were the make of the psu's? How did you connect the 24pin mobo connector of the 2nd psu?

Atleast post a step by step tutorial as suggested by topgear & explain each step briefly and not in sms language.

 

[abhidev]

It is a bit tricky but, don't any1 of u know about it?

Dual setup of PSU..m sorry but i have never heard of it...how is it done???

 

[S_V]

Actually Dual PSU can be used and it's little tricky..

let us wait what he says about it...

All i can i give small hint... Black and Green Wire .....

 

[rajan1311]

Dual PSU setup is generally done on servers, some consumer mobos also support it, but if you try it on your PC, it will most probably kill the board....

A friend(thebanik) tried doing it on his Classified and UD9, both gave an warning/error on mobo....

If I were you, I would not go for a GTX570 on a 450VX. Wait got the GTX 560 if you dont want to change your existing PSU.

I've used this for test PSU and fans !

But some custom pc makers like origin and there Big O model has 2x psu inside but it uses a little bit more sophisticated method I guess.

 

[S_V]

It's not any sophisticated method,, Just an quality Dual 24pin ATX adapter cable will do all the Job. Yes, it's safe to do so.. I have seen and installed many Rigs in office using this method.. It's not for only Servers... If anything goes wrong, either low-profile SMPS or user Mistake..

Hotwire or Jumpstart Black and Green wire is also safe method but it's just for Temporary solution for testing PSU and Fans like TopGear said... and not for continuous usage...

 

[topgear]

^^ ok- thanks for the info buddy - it was very informative.

i used the green ,black wire method.i even ran my gpu(5770) with it...u have to just turn it off/on manually.
what the alternative method ?please explain it broadly,because i have a plan to stick again with dual psu as i m gonna do crossfire.

As topgear said in his first post, maximum power consumption of the GTX 570 is 370W. If that is right, a 450W is never be able to handle that rig. Even if it can, it would be too risky. So, dual PSU would be really helpful in this case, if he can afford another PSU.

I've used Dual PSU, and still I'm using, 400W+400W. As right now I don't have a GPU, I'm powering my motherboard with one PSU, and HDD, ODD, and other hardware with the other PSU. I used the paper-clip method, though.

Mr. Mohiuddin is right, it will be a wise decision not to power the GTX 570 + the whole rig with a 450W PSU.

I don't agree with you and i guess no one will either. Asingh's posts make sense unlike yours. Two psu's can't be stuffed even in a full tower cabinet.

Why not? You don't use up all four of your ODD bays, do you? a PSU will perfectly fit in two of those.

 

[mohiuddin]

totally agree with @[Dee] and @S_V .

-----------
^^800w power but no gpu?
bro buy a 6950hd(better deal still now for bucks) or gtx570 ASAP(as soon as possible.

@ mohiuddin & [DEE]

Guys please share a tutorial and pics to support your claims. We all are eager to see what this dual psu setup can benefit a user in case he or she wants to add a powerhungry component later to the existing inadequate psu without changing it.

Support your claims or no one will believe.

Ok mate thats good but we don't need a 2nd psu to power fans and lights but components as well. Lets say the OP in this thread wants power his gtx 570 with a vx450. Most members say the psu falls just short. So in this case, if op purchases another vx 450 or a corsair cx400, what will he do to power the 570 efficiently?

Please explain in brief along with the pros and cons of such a setup.

 

[topgear]

^^ for him it's best to use the method of Dual 24pin ATX adapter cable said by S_V. That way the PSUs will balance the load between them efficiently and there will be not turn on/off issue - check out the last pic.

As topgear said in his first post, maximum power consumption of the GTX 570 is 370W. If that is right, a 450W is never be able to handle that rig. Even if it can, it would be too risky. So, dual PSU would be really helpful in this case, if he can afford another PSU.

Why not? You don't use up all four of your ODD bays, do you? a PSU will perfectly fit in two of those.

I've never said a GTX570 can consume 370W - seems like you have confused things a little bit. I said total system power consumption with a GTX570 would be that much.

A GTX 570 an consume around ~210W under full load.

i used the green ,black wire method.i even ran my gpu(5770) with it...u have to just turn it off/on manually.
what the alternative method ?please explain it broadly,because i have a plan to stick again with dual psu as i m gonna do crossfire.

This can be done - no doubt about it but I think it's not safe to do so. If for some reason the wire connection/paper clip connection gets loose there will be some major issues and you have to manually switch on/off the PSu everytime.
Another thing is you have to decide which components should get power from which PSu and there could be load balancing issues.

here's a guide for you guys and it's in plain English :

Guide dual psu and test psu : a how to guide. - bit-tech.net Forums

I think it's little bit complicated to setup like this anyway.

Here's some more guides :

The Bitspower X-Station Multi PSU Module lets you run up to 4 power supplies simultaneously by connecting them to the connectors on the X-Station and jumping one of the X-Station's connectors with the included ATX Power Supply Jumper. This module is a must for enthusiasts that want to ensure clean power for their video cards by providing them with their own power supply

Sweet trick there said by topgear. I haven't went through the entire 8 pages of the thread but i rather not suggest u to do this as the this might disturb the consistency of the PC. Now u might have ur own reasons & this might have been said before but there is an easier way to solve this problem. Don't buy GTX570, wait for GTX560 which will be available by the end of this month, that card will have lower TDP and will draw power similar to GTX460.

Now u might already got the card, if thats the case, get anything like CS600W or VX550W.

@Topgear,

It's nice of you to post such tutorials...

It's that last Dual ATX adapter we are using in our Office setups mostly.. Our office inventory imports them from frozenCPU as well( I wish frozenCPU should start services in INDIA, they are awesome at getting all the modding and watercooling setups sales, you name they will have it). . USA Branch will take care of these inventory stock and sends us to here in Indian Branch for us to do the Jobs. (This is How ,i got circle in USA to send me some tech goodies for my own rig off the record..US tech Guys are very friendly at first i thought this is not possible and They are superb in knowledge too)

Please don't ask for Pictures ,as you Guys know Photography is strictly prohibited in MNC companies... And especially when we tech Guys are around ,all cameras will concentrate at us only.. it's not that they are suspicious about us.. It's just they are worried about super tech Guys knowledge... YES, i am one of the Senior Administrator of IT specialist Group. I am proud to say that loud... ..

@ topgear

Thanks a lot mate for all the info.

But i feel all the methods discussed above are a bit too complicated for a novice & pro user alike. As you said there may be load balancing issues and the methods discussed above were not running any state of the art hardware like a multi gpu setup or something but were for experiments.

I reckon there's a lot of risk involved to practically implement the ideas and use dual psu's to power a system running multiple videocards, harddrives , optical drives etc.

I still don't agree it to be a viable solution for practical use & only sounds good on paper cause a lot of skills is required.

None has put a dual psu in a full or even midtower, so those may be for experiments and seldom for even test benches.
