trying to buy a new PSU for 3GPU's

post #1 of 12
Thread Starter 
I am helping a friend build a PC, he's got pretty much identical parts to my rig, a i7 950 on a x58 board(Will help him OC it to 4 GHz or More) and about 12GB's of Ram. He wants to get two 560Ti's in SLi and use his old 260 for physx, And he might upgrade to two 580's in the future. I wanted to give him my old slverstone strider st600F but it only has two 6Pin PCI E connectors, so I doubt that will work with a 560Ti Sli setup. So he needs something with 4 or 6 connectors.

What should we get? Any new PSU's that have 4 - 6 connectors and would do the job? I was leaning towards products from Silverstone or Corsair, nothing too expensive tho, maybe around 850Ws? so not sure which specific brand or model would be the best buy.

From jonnyGURU: "At this point, I'm starting to believe Corsair couldn't produce a turkey if they tried to. As is the case with every other Corsair unit I've tested, the TX950W has come out a winner. It's a big bad 950 watt unit for an affordable price with nice stable voltage regulation and excellent efficiency. If you're not into modular, what more could you ask for?"

You're probably looking in the 850-900 range. I don't think that, even with the GTX 260, you will need more than 850-900 at max load. My suggestions are the XFX Pro 850, the TX850, HCG 900, or anything along the lines of an HX850, Seasonic, or SS, but if you're not looking for modularity, they're a bit more expensive.

Yeah, If you get a Corsair PSU make sure its a "v2" version, they tend to be better.
I agree with the TX850/950

Okay, so looks like I am gonna have to be looking into the 850W + range.
I was keen on getting a fully or semi modular PSU tho, How about the Silverstone Strider's 850W's? The Silverstone ones seem to be going for a bit less than the Corsair ones where I live.

Thanks..giving reps where deserved..

"GeForce GTX 560 Ti in 2-way SLI

A second card requires you to add another ~175 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).

For each other card (3-way SLI) that you add, just add another 200 Watts and 20A on the 12V rails as a safety margin."

Yes, I will be helping him OC it to 4GHz or more..So adding 200W extra for each card thats around 600W alone for 3 GPU's. So it has to be over 850W or more.. Thanks. Are there any specific model of PSU's that has 6 PCIE Connectors?

Wanting to go Silverstone at this stage.

Only if he's going for 580s, otherwise 750W would do, the physx cards pull very little as they are never stressed.

Also, the Silverstone Strider Plus 750 and 850 are both excellent units.

OP, you can always check here to use a reliable calculator. You really won't need more than 850W, and that's with SLI 580s. If you're looking for modulars, try this, this, or this. Some 850 units go up to $200+, so look around for deals.

Thanks But I actually had a Corsair 750W unit on my past rig, and every time I would add a physx card to my SLi setup, the thing would crash / auto shutdown. So I have some doubts about a 750W unit being able to pull it off.

definitely would look at getting the Silverstone Strider Plus 850 Unit.
Any idea if they have 6 or more connectors? You know for 2 or 3 cards
