Advice on power supply

[pootklopp]

I have a build as recommended by this site, however I got an outside recommendation from a tech guy.

Original build:

New recommendation: just a change in power supply

I want to put orders in tonight on the sites so a quick response would be much appreciated.

He informed me single rail builds are of higher quality

The XFX you listed is an older model made by Channel Well.

You should be choosing between these two models:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006

As far as preference, they are both made by Seasonic, and the same warranty. The XFX has 62a on the 12v rail vs. the Corsairs 60a. They are nearly the same unit.

yes sorry that is the one I was looking at, thanks for the help

The Corsair you listed isn't made by Seasonic, it's made by CWT. Less reliable and less efficient. The only Seasonic-made Corsair 750Ws are the TX750-V2 and AX750 (the HX750 is made by CWT as well, for some reason).

Also, to answer OP's question, the XFX is great. Go for it.

 

[pootklopp]

so the most reliable would probably be the TX750-V2? But no crossfire on that guy...

 

[pootklopp]

The only reason this got brought up was because I was told the XFX was not single rail. Is this correct? I was told single rail is better built and more reliable

 

[mousseng]

so the most reliable would probably be the TX750-V2? But no crossfire on that guy...

No more or less reliable than the XFX PRO750. Those two units are almost 100% identical (62A, 744W on 12V rail, made by Seasonic, etc). The only differences I can discern are the power connectors (XFX has 2 6pin, 2 8pin, Corsair has 4 8pin) but that really makes little difference. Choose whichever suits your fancy.

Also, depends on what you plan on crossfiring (or are you referring to the Corsair not explicitly saying it's Crossfire-ready? Because it is just as ready as the near-identical XFX).

Edit: You are correct, it is a single-rail PSU.

Ok all this is new to me so I was more going by what I have been told. I guess I was just asking what was more reliable and a better fit to my build. Which is this:

http://pcpartpicker.com/p/fqDR

I want to keep it open to adding a second 7870 in the future. While I'm asking I was thinking of adding a second monitor at this point, would this be a big enough demand to justify the crossfire now?

This machine will be used for School/ Video Viewing/Gaming. I will be running Autodesk software (AutoCad, Architectural Desktop, maybe even Maya in the future) and Adobe software. I usually watch videos (streamed or downloaded) to an external TV (hdmi out). Then some gaming on top of that (Day Z Mod, maybe some more)

 

[mousseng]

The TX750-V2 should be good for two 7870s; this shows it at 500W at load.

Also, I wouldn't recommend gaming on two monitors - you'll have the center of your "screen" right between the two monitors. If I recall, you can just run a second monitor off your Intel HD 4000 (don't quote me on that, though).

 

[pootklopp]

Yeah I would not run both while playing, since that is the least important of my pc criteria when needed I would run one for browsing one for work.

I just want to verify, even though Newegg says "crossfire: no" it can still run crossfire the same as the 750TX and XFX PRO750?

 

[mousseng]

Yes. If you want to be as sure as I am, here is AMD's Crossfire certification page for the TX750-V2. It greenlights 2 6970s on it, and the 7870 draws much less power than a 6970. The TX750-V2 has all the proper connectors for it (it has four 6+2 pin connectors; 7870 Xfire needs four 6 pin connectors).

 

[pootklopp]

thank you for your help everything is on its way

That's what I said, Channel Well, you really should read the post before replying to it. And because you have poor reading comprehension skills you get the best answer. Pathetic.

? I'm confused then. The OP linked an older, CWT-made XFX PRO750, which you said was older and CWT-made. Then you linked the newer, Seasonic-made XFX PRO750 and an older, CWT-made Corsair TX750. I pointed out that the Corsair was not Seasonic-made (as you said it was), but was in fact a CWT unit, and then linked the newer, Seasonic-made TX750-V2. What is it that I read wrong?

I'm sorry you think it's pathetic, I was only trying to help the OP.

I linked a version 2.2 which is made by SEASONIC, at least according to the description.

Newegg either has their model numbers or their descriptions mixed up, not my fault. If I bought one that said V2.2 in the description and received a non V2, I would send it back.

 

[mousseng]

Ah, I see, there's been a misunderstanding. The "v2.2" bit is in reference to the ATX12V specifications, not the power supply's version. It doesn't say Seasonic anywhere on the page, though, so I'm not sure where you saw that.

 

[geekapproved]

This is the link I meant to post.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021

Where they decided to place the words "V2.2" was a bad idea because thats where they listed "V2" on the other link. You can see how that could get mixed up.


I never said anything about Seasonic being listed on the page.
