Hi there,

I just got a new GTX 570 and it requires two 6 pin connectors from the PSU.

I was wondering, now I've actually never looked in to this either, so this would be a learning experience for me;

Can I hook up both 6-pin connectors on the same line?

God, I hope that makes sense.

Basically, my PSU offers 1 cord with two 6 pin connectors on it. Both on the same cord hooking up to the PSU.

Can I just use both of those, or do the connections have to be separate? I guess I'm worried there would be some type of issue with one not offering 100% of what it should offer power-wise.

Forgive me if this seems like a newbie or dumb question but it's something I've always wanted to know, and now mandatory, I suppose.

Thanks, these forums are amazing!

Hope this better explains what I'm trying to say, haha!

Great paint job, what PSU is it, depends on the cabling it should be separate on the GPU but some cables are sheathed together and are actually separate cables

 

[RYKIN]

It's a Antec PSU.

Model: TP-650

"True Power" brand, I guess?

Not a modular PSU.

As stated below, we would recommend atleast a good quality 750W for that Graphic Card. However to answer your question, with that PSU you would need two separate 6 pin connectors.

You have a good quality (SeaSonic made) PSU but it's underpowered for a GTX 570. You need to be at 750W for that GPU.

New PSU it is!

Thanks guys !

Gonna order one now!

Which of those would you recommend, Tyree? Of personal choice or quality.

I'm thinking a good modular PSU would be great. And wow, these have come down in price by a lot.

 

[Tyree]

I use XFX & SeaSonic but they are all made by SeaSonic and are top quality. Modular is great for cable management but it comes with an added price.

 

[RYKIN]

The Corsair gets amazing reviews, but it's not modular.

Also, should I take the 570 out and put my GTS250 back in?

I have it hooked up via one 6 pin connector, and the conversion connector that makes me connect 2 4 pin connectors (to two 3 pin connectors on the cables from the video card).

I hope you understood what I said.

I was wondering if I should just take it out for now. Will it harm it to have it installed as long as I'm not using it for a stressful game?

EDIT: I can always do up another Paint picture if necessary!

The true power 650W due to EPS design standards has 8A less than the XFX 750W. Are you telling him to spend $130 for 8A (96W)?? :sad:

Plus you guys are completely overkilling the requirements for a graphics card that has a TDP of just over 200W. His machine would struggle to pull 420W from the wall MAX (35A on 12Vrail) as shown here. Even with derating you are wasting his money. The TP-650W can provide a continuous 648W on the 12V rail.

To the OP, your current PSU is more than fine, and Im happy to argue with anyone using emperical evidence to prove it. And if you do, even with 30% derating, please tell me how its will exceed 455W (648W derated) on the 12V rail.

To the OP, purchase a wattmeter that plugs into your wall socket, run your computer whilst gaming for an hour and record the highest wall wattage. It wont exceed 350W. I will pay for the wattmeter if im wrong.

To answer your original question, yes, you can plug both PSU 6 pin PCIe connectors into the same card. That's what they're for.

 

[Tyree]

Your 650W is fine for the GTS 250 but not for a GTX 570. Using the 650W PSU with the 570 GPU is not recommended.

 

[Tyree]

Considering the OP wants to know if the current PSU will suffice, the answer is a resounding YES.

For the short term, possibly, if using a top quality PSU (i.e. SeaSonic-XFX-Corsair)
Would we professional builders/repairers suggest it or use it, certainly not.
To insure clean sufficient power to help prevent damage to the OP's investment for extended use we should/would recommend nothing less than 750W.
Nvidia recommend 550W minimum for a GTX 570. 550W x 30%= 715W.

it is not the only thing to disappear

Thats not how you derate a psu btw. but anyway, there seems to be a culture of overkill. But i understand if you want to follow that path, my only concern is when you are not paying for it. As an electronic engineer with post doctoral degree, I assure you I understand very well the physics and real world realities. I am suprised however that you delete posts that differ from your own understandings. Wouldn't it not be better to clarify your situation with empirical evidence. Is there a policy that Hardware people need to follow may be? Anyway, Im new so ill shoosh, but I will with respect continue to put my view across ok?

[Is there a policy that Hardware people need to follow]

yes there is

check old threads and you will see your recommendations fail and a psu upgrade fixes

 

[Narcissist]

Mate, been around the traps for a long time, no need to be condecending, but your rules are overkill. But ill conceed there are a lot of **** PSUs out there, but a standard 40A rule on PCIe cards is rediculous in the extreme. I also note, the main people suggesting this don't have any specs up. Interesting that.
