GTX 470 Tri-SLI and Power Supply - Page 4  

post #31 of 37
OMG somebody's wrong on the internet! I have to respond!

Let it go guys. The OP has enough information to make an informed decision.

Because almost no two people have identical systems, so Zmanster needs answers that are specific to his.

This.

I like this idea a lot!

No need to get all worked up about it tongue.gif the worst that can happen is the unit will shut down harmlessly if it thinks you're drawing too much power. But that's not going to happen. smile.gif
Ha, this is the first nice thing I've seen said about a Huntkey power supply! smile.gif hehe

I don't know what I'd do without you and the other PSU gurus on here, man!

I will offer my analysis:-

Refer to the 5 pics below.
Pic 1 shows the five rails (12V1 to 12V5) with 18A capacity each.
Pic 2 and Pic 3 show the the what cables go to which rail. Note:-
-12V3 is for two 6-pin PCIe connectors
-12V4 is for one 8(6+2)-pin PCIe connectors
-12V5 is for one 8(6+2)-pin PCIe connectors

One 6-pin PCIe is rated at 75W and this means 6.25A per connector. This means for 12V3, it supplies 12.5A (with a reserve of 5.5A).
Basically, one 8-pin PCIe is equal to two 6-pin PCIe. So, for 12V4 and 12V5, each supplies 12.5A.

So, I suggest use two ''8-pin-PCIe-to-two-6-pin-PCIe'' converters. See pic 4. One for 12V4 and one for 12V5.

Then, for connection of GTX470 3-way SLI, I propose:-
12V3 for 1st GTX470 (two native 6-pin)
12V4 for 2nd GTX470 (native 8-pin spilt into two 6-pin)
12V5 for 3rd GTX470 (native 8-pin spilt into two 6-pin)

Link:http://www.itocp.com/htmls/47/n-647-3.html


Side note:- it seems that there is a newer version of the x7 900W because the official site states that the PSU has three (6+2) pin and three 6-pin PCIe connectors. See pic 5.

Hey, brett, it is good to see you here and as a moderator:thumb:

For reference, the X7 and Jumper series from Huntkey are decent units.

Are they units I should confidently recommend?

They are fine units, it's just that Huntkey has no presence on the North American market. You can find some of those units under different names here since Huntkey OEM'd them, e.g. the Rocketfish 900W which is a Huntkey X7 900W.

Even though it's a Huntkey, they are actually quite solid units. About a year and a half ago, I almost bought one myself in the form of the Rocketfish 900W at Best Buy for $129. That's about the most I'd spend on one myself though, looking at the other competition in the price range (you see, DF, I know quite a bit about this PSU thumb.gif)

Other than that, I'm locking the thread, as the OP has enough info to make informed decision.

Windfire and I suggest using two 8-pin to 6-pin adapters for this application.

Zmanster if you have further questions or really feel this thread should be re-opened, feel free to shoot me a PM.
