Will this power supply be enough to crossfire 6970s?

[Slushyspy33]

Hello I was wondering if I would be able to crossfire 2 sapphire radeon 6970s with this power supply.

http://www.sentey.com/en/xpp-725-watts-xpp725-ps

full specs(that matter):
i3 2120
3 120mm case fans
1 DVD-RW drive
1 TB seagate drive
1 60GB corsair Force SSD

I've heard many stories of crossfire with this power supply but I was just wondering because I know the 6970s are an older card and need more juice than the newer ones. It doesn't have all the cords but it comes with adapters.

No it can't it's a very poor quality supply , and it has a very weak 12v+ rail, and it's also lacking PCIE power connections , it only has 2 you need 4.

This will do it , and great quality made by Super Flower.

It will work as long as the two 6+2 PCIE cables are enough.

That Sentey is actually based on a more budget level Super Flower Design. Good manufacturer but this is not a Leadex.

Despite only being rated for 80+, it actually is a Silver unit under the lid.

No it can't it's a very poor quality supply , and it has a very weak 12v+ rail, and it's also lacking PCIE power connections , it only has 2 you need 4.

But it says on the page it has a very strong Rail...

See my edit above too.

Your PSU is good. As long as it's less than 5 years old and have the connectors, there isn't much reason to buy another.

If you do upgrade, the B2 that Blackbird showed you is a higher end SF design (Golden Green), just below Leadex.

Sentey is just the sticker on the box. You gotta see what's under the hood with these things.

A 725W power supply with 2 PCIE connections and Max +12V rail of 48 Amps is pretty weak.

Max +12V1 Power (W) 576W 🙁

 

[damric]

zOMG BLACKBIRD Shame on you for not doing your homework!

It's actually got 64A 12V rail ><

My only concern is that it is an older platform so the OP's PSU might be worn out anyway.

 

[Dark Lord of Tech]

That power supply is poor.

No. Poor is the CX's that you put in last year's Builder Marathon (And won?).

I'm sort of new to tom'shardware and I don't know who to listen to when it is 50% 50%. All the other threads I've posted are one wayed.

 

[Dark Lord of Tech]

You mean crushed the competition.

I've had people PM me saying thank you.

 

[Slushyspy33]

I mean I don't to buy the other GPU and find out its not enough power, but I also don't want to just throw money out the window.

How old is it? That's what we need to know.

That's because SF did not pay to re-cert it. The same thing happened with the Libertas (ATNG).

Its brand new... I haven't Installed it yet.
Ok I just thought of something!
You know amd cards can crossfire if the GPUs have the same structure, so, what if I got a card similar the the 6970 but it consumed less power.
Please share your thoughts about if this is a good idea, and if so, what cards?

Power is not an issue here. I'm running a severely overclocked crossfire set-up on my SF 550W, lol.

 

[damric]

Hold on, BB might be right. This is the XPP model. Damn now I don't even know what OEM that is.
