New PC build

[Dark Mantis]

You just got in there with the same comment as me. The Tagan has it's ouput on the 12v rail split in two whereas the Corsair has a single rail setup which I must admit to preferring. I was also going to mention that if babdi wanted to run dual GPS in the future they wouldn't be powerfull enough.

[absic]

Yes, this is true, none of the PSU's that Babdi has posted would be powerful enough for a dual GPU set-up.

The problem here, as with all new builds is one of cost against availability and what the PC will actually be able to do when the available components are put together. Again, I am looking at the overall results that are required and trying to keep in mind the options available and the net result of putting these items together.

Things such as a higher powered PSU or second graphic cards, although nice, are not essential for the first build and can be easily replaced when availability and/or budget allows.

Whilst you are correct, I think it is also valid to look at the longer term costings. It is not cheaper if you have to replace a part in a matter of months or so because it won't run some new device that you want to install. What I am trying to say is that an paying extra £30 now would make more sense than having to pay another £120 in a years time to replace a PSU with something more powerful.

Yes I take it we are all conversant with the specs. It was just trying to help you come to a sensible and financillly viable decision taking into account any slightly longer term ideas that you might have.

Hi Babdi,

I would still go for the Corsair PSU as it has a single rail which I have found to be more robust at supplying the necessary power. The dual rail design of the Tagan, appears to be OK but I have found out the hard way that such designs can sometimes cause problems, as the total output is actually split between the 2 rails.

I know that it is a tough choice, especially when the extra cost is involved, but my advice is offered from experience and I really don't want you to make the same mistakes I have made in the past.

[babdi]

I appreciate your ( absic,DM) concern and willingness to help in my choice making.

As said in one of my posts I will not be going for dual GPU in future and that is the reason for choosing UD3 board. I do agree PSU should be future proof
A 20% higher power rating than required should be sufficient is what I feel. Yes, cost is also the factor.

I may take last minute decision to go for Corsair 850W if situation demand. All depends how much I get for the old rig.

If the offer is weak then this is what I may do keeping other things same

change the mobo to UD3
go for HAF 932
switch to H70

[Dark Mantis]

This is it. It always comes down to money at the end of the day and whilst we can all see the pros of going for the better quality device if you haven't got the rupees then it is a non starter.

[babdi]

Yes indeed DM. We dont have deep pockets, do we ?. Such discussions are a intellectual stimuli and helps in polarizing the purchase.
I must admit inputs from both of you has made my decision making easier and clearer. I now know exactly what will be the outcome based on the choice of hardware I choose.
Thank you very much

[absic]

I now know exactly what will be the outcome based on the choice of hardware I choose.

Now now Babdi, don't get over confident. If we could all guarantee the outcome of our purchases DM and I would never have wasted our money on Western Digital Caviar Black SATA 6GB/s HDD's. 

The final choices of components will always depend on ones finances and what items are actually available at the time of purchase and we can hope for a certain outcome of how these components will work together, based on our experiences and the feedback or reviews that we may have read about on the internet. But there is always the risk of a challenge when the parts are put together, that's what makes this aspect of computing so exciting and sometimes, so frustrating.

Yo, wassup?

I have a similar issue my build is the GA-890GPA-UD3H 1055t, corsair xms 8gb. and trying to decide on grapics either the 5850 or a gtx 460/470
i,ve heard of the amd nvidia issues. if you have tried it with this mother board can you let me know how it works out?
 and another thoery.. say i use a 5850  and buy a gts450 dedicated for physx... will it be ok on a amd mother board because it seems to work fine on intel ones. using a physx hybrid mod driver.... any ways let me know ...peAAAACEE!

[Dark Mantis]

Wwaassuupp!! and welcome to the forum.
Personally I would recommend the 5850. It is a rock solid card compared to the 460 which seems to be having many problems at the moment. As top wheter you can run one of each on the same motherboard singly I don't see why not but I must admiot this is absic's domain and he will know a lot more about the AMD foibles than me.

[babdi]

Okay This is what I have moved to.

That all looks good to me apart from the fact that you are running your memory at 1600 rather than the safe recommended speed of 1333. You are chancing damaging your processor by doing so.

[absic]

As DM says, you are taking a bit of a gamble by running your RAM at 1600MHz. However, if you are only running 2 sticks of RAM, one on each channel, you will probably be OK but I wouldn't risk it myself.
