My Antec Tp III 650 for a GTX480??? adapters needed?

[Delavan]

Hi all!

I'm sure you can help me with that.

I use an Antec True Power trio 650 Watts, 52A on the 12 volts rail. It's a Seasonic-built model, sharing "most" but not all, components with the Corsair HX620...it's not quite as good, but working great for 2 years.
It's officially a multi-rail PSU, but looking at pictures of the soldering points on the Board (I don't have the technical term of this), they all go to the SAME spot. So, in fact, it's a SINGLE rail 52 amps PSU design.

From JonnyGURU's review:

In addition to all of this; I also couldn't find any circuitry beyond the traces that actually "divide" these rails. And on the load tester, I found that there actually is no OCP, so there is no 19A per 12V rail "limit" either. Just seems to be a single +12V rail PSU! Which actually isn't such a bad thing, but dammit! The label says I get three +12V rails and the PSU is called the "Trio" after all!

So, it has 2 X 6-pins PCI-E connectors. Fine for my GTX260 OR a POSSIBLE GTX470 (2X6-pins according to PCB pictures). IF ( A BIG BIG BIG IF) GTX480 is affordable/meeting my price point...it had 1 X 6-pins and 1 X 8-pins connector. I'm doomed.

Or can I just use a 6-pins to 8 pins PCI-e adapter like this

to get it to work without ANY stability issues???
I'm running the computer in SIG, there is NOT a huge load on it, IMHO.

I mean, if it's not a GTX480, it could be any other GFX card that has one of those 8pin connector. Would I have to buy a new PSU???

Your PSU is powerful enough for any single-GPU card within the forseeable future, including nVidia's upcoming models. You can use an adapter if necessary.

The Truepower Trio series uses a completely different platform from the one used by the HX620.

Thanks!

Well, I read the review again and yes Jonny mentions at the end that it's not the same platform, you're right!
So the "adapter" option is feasible. So what is the reasoning behind the 8-pin connector vs a 6-pin? I mean what was the purpose to change if (if not just to sell more PSUs)?

[Zero82z]

An 8-pin connector can supply twice as much current as a 6-pin can.

LOL, I read that wrong the first time , i thought you said it wasn't powerful enough to run any single - GPU card in the foreseeable future, was just about to go on a rant.

[_dangtx_]

very nice and super quiet unit there!

card probably will have somethign in the box in the form of an 8pin

[Delavan]

Thanks all for the answers!

Well, I kinda "hurt myself" dreaming about a GTX480 priced below $500.00...I know WISHFUL THINKING/I'm on Crack or something...But I want to be ready for a 8-pin if need be.

As if there is a 6pin to 8 pin adapter packed with the GTX480, I don't know, I never owned a 9800GX2, GTX295 or one of the ATI dual-gpu cards... I don't know if they usually pack an adapter in those cards.

I'll probably settle for a GTX 470...the HD5850/5870 gray screen of death makes me shiver, I don't want to go RED...
