GTX 470 Tri-SLI and Power Supply - Page 2  

post #11 of 37
Sigh.

While I wouldn't go out and recommend a Huntkey power supply, this one should have enough power to handle a system with three GTX 470s in SLI.

I mean, if the review below is referring to the exact same model that Zmanster has, then its +12V capacity is 864W (72A):

In other words, Defoler: he's not limited to 216W.

864w seems low for a 900 watt psu, I have a 850 psu and its rated 70a 840w.

I don't know anything really about multi-rail PSUs though, which is why I bought a single rail.

Actually, I should be surprised by this Huntkey's +12V capacity. Check out this lowly Apevia unit:

http://www.newegg.com/Product/Produc...82E16817148036

It's a 900W power supply with a +12V capacity of 744W.

What's more, the 900W Antec High Current Gamer's +12V capacity is 850W:

http://www.newegg.com/Product/Produc...82E16817371050


So 864W isn't bad. However, I will assume that this 900W Huntkey's power delivery is not as clean and as stable as higher quality 900W units, like the HCG.

Are you serious? Really?

Lets try this again, so even dummies can understand (as the OP seemed to already understand).

The OP is trying to push his system.
He wants to put a GPU, which pulls 75w per PCIE 6 pin, connected to molex lines, which are 99% of the time graded just to 75w.
He also wants to put his pumps on these lines.
He also has fans and other things.

Also the rail doesn't have 72A, its stupid to point this out, as the other rails have their own work (other GPUs, motherboard).

He is going to push a 18A rail over its spec, over a long time.
That, is not fine, its not 864W, or 72A, not recommended.

Unless the OP deside to ditch the OC, which he doesn't, I would say no, its not a good idea.

In theory the PSU has enough power.
In practical use, it will not.
If you don't know the difference, its a shame.

Anyway, no reason to continue and argue with people who have a hard time understanding something very simple.

Wow. You've really killed my motivation to reply to you, but I'm a professional and so I will reply anyway while resisting the urge to give you a piece of my mind. I should be reporting you for being this rude and condescending.

lol I'll just wait for Phaedrus2129 to come along (that is, if he should happen to see this thread).

All I can say is this: there's no problem using the adapters that combine two 4-pin molex connectors to power one PCI-E connector.

So in other words: Zmanster, I recommend that you use the adapters instead of splitting. Sure, it won't look pretty for pictures, but it will work.
