Do Corsair PSUs have the appropriate connectors for the new Nvidia 98** cards?

Do Corsair PSUs have the appropriate connectors for the new Nvidia 98** cards?

There is a mechanical issue with the 9800 cards and virtually ALL PSUs. Nvidia has made the locking tab slot on the card narrow enough that most 8pin and most 6+2 pin connectors will not fully snap in. They will work electrically but, the tab will not lock the connector into the slot on the card.

Corsair PSU's will work just fine electrically but you may either have to leave the tab out of the slot temporarily or cut the tab off. Nvidia is supposed to supply their partners with a proper adapter within a couple of weeks to negate the need for this. If you can't wait or if your cable will not work with the tab on it, you can clip the tab off the PCI-e cable.

OFFICIAL CORSAIR STATEMENT: If you need to clip the tab on the PCI-e connector to make the connector work with these cards, it DOES NOT constitute a voided warranty.

Any other modifications to the cables or PSU as stated by the warranty terms WILL constitute a voided warranty.

Thanks YB!

Yes... it is a FACT that virtually ANY 6+2-pin PCIe connector is going to have a bit of a fitment problem in these "shrouded" Nvidia cards.

It's good to know that Corsair will stand behind someone forced to "customize" their connectors.

Just keep in mind that you may not have to clip the connector. I've gotten a few of them to fit by just "wiggling" the connector into the hole. With some "English" you can often get the connector to fit.

Hmmm.....what will we call it in the UK JG?

Why couldn't nvidia put a normal PCIe connection on their new cards, why play with the locking tab /shakes head

 

[jonnyGURU]

Who knows. With easily 90% of the PSU's out there using 6+2-pin PCIe connectors with either a wide or off-set clip, there is ZERO reason for Nvidia to not allow more clearance for the connector. The shroud, at least in the region of the power connectors, is purely cosmetic.

Here's a note for 9800 GX2 buyers:

If you own a corsair PSU and you don't have an 8-pin PCI-e connector then you can't use the 9800 GX2. But here's what you can do:

Contact corsair customer service. They will ship you a 6 pin to 8 pin PCI-e adapter for free (pay only shipping).

Another option (and what I did since I do not own a corsair psu) was to purchase the BFG 9800 GX2 which includes a 6-pin to 8-pin adapter.

Nvidia, XFX, eVGA, etc. do not recommend using an adapter apparently, but corsair reps are confident that a HX620 will power the 9800 GX2 (despite lacking an 8 pin pciE connector), and BFG obviously includes the adapter, so the warranty and liability is on their hands if the card should fail.

um, I think what corsair does is send you an actual 6+2 pin plug for hx520/620 since they're modular. I first heard about this (from a yellowbeard post I might add) before the vx line came out, however, so it is possible that they simply include the adapter, instead.

My hx620 came with 2x6 pin adapters and 2x6+2 pin adapters. I'm not aware of ANY hx620's that were shipped with 4x6 pin adapters. My hx520 came that way but since it's in my file server with the 7300gt fanless I figured that I could get away without the 6+2 pin adapters for it

Just relaying what I found by googling and going on corsair's forums. I don't know what comes with the HX620 but I am telling you what they will do for owners.

Please tell me the difference between a 6pin-to-8pin pcie adapter versus a 6+2 pin that attaches to a 6 pin connector on the PSU? I would think no difference.

Apparently NVidia actually followed the PCI-E spec - it's the PSU manufacturers that did not. Weird.

hey SparkyJJO is JG the same thing as junk

its a shame that they bring out this stuff and almost no power supply plugs will fit it.
BUT it has to be the ps manufactures fault.
HELL they are Nvidia and every ps is wrong or they are.
of course I would think that the ps manufactures are using a little off spec so that they can cut cost. But at the same time I don't see how making a hole in this thing 1/1000 of an inch larger is going to make a difference. they could have made a boot if it reguired a seal and not gone this rout.
HELL for the price they could send a tech with some silicone to seal it up

Actually, there is no spec for the connector. The newest connector specification from PCI-SIG isn't even final. It's dated 12/2007 and it's a draft. And in that draft there is no clip width specifications. There isn't even clearance zone specifications for the clip width/placement. There is only a clearance zone for the clip to detach from the card when you squeeze the release tab.

Actually, "JG" as in "Jonny Gerow". He was addressing me.

Yeah... it's a shame that Nvidia couldn't even do a fitment test with just a handful of units on the market as opposed to their elite group of people they work closely with.

That has to be sarcasm because I would never call Nvidia infallible, especially when sized up against virtually every PSU manufacturer in the world.

Cut cost? The 6+2 connector actually cost MORE. The problem is, the clip on a 6+2 has to be made to engage both a 6-pin PCIe power connector AND an 8-pin PCIe power connector at the same time. There's no cutting costs here.

That's just it. They (Nvidia) could have made the hole larger. There doesn't have to be a "seal" around the power connector. It's strictly for aesthetics.

Come on jonny. Those connectors cannot possibly cost more than 5 or 10 cents. Maybe 20-25 cents with the wires. That kind of stuff in bulk costs practically nothing per unit.

It may cost $3.95 if you buy one of them at Fry's or something though

2¢, 5¢, 20¢.... Regardless, it's MORE is it not? I didn't say how much more, but it is more. My argument is it's by far a way to "cut costs".

Essentially, it's like taking your cost for a regular 6-pin and then multiplying by two because you now have two parts, and you have the labor of wiring the connector twice (once for the 6 and again for the 2.)

A third option is to buy the adaptor for $5 direct from BFG. Shipping and tax may apply.

Thanks for stickying this JG!

Good find... those are fairly hard to come by on the internet. Google searches come up with very little to go on.

I better email silverstone customer support about this for my op1200

the hx520 and hx620 are modular, so you should be able to get the actual 6+2 pin cable instead of just an adapter. I believe that the actual amount of power supplied would be the same either way, but the 6+2 pin cable is a more elegant solution, as is the modular design vs having 50 cables wriggling around in your case like a pack of rattlesnakes

Essentially it does the same thing, it just puts 12V at 2 contact points, in parallel. Either way it makes no difference electrically (as long as the wires are not maxxed out for current, which they should not be), although the 6+2 pin would be more discreet.

 

[bryanW1995]

the 6+2 pin is cool, but I personally didn't even know that I had it until I read about it in yellowbeard's post last year. Also, a few weeks ago I told ANOTHER person here on the forums about it and HE was surprised that he had it, too. It's almost TOO discreet
