DFI sli-dr and 20 pin power supply. How many are using 20pin ??

[thesaucier]

How many are using a 20 pin power supply? Have any of you had damage and what were your setting if you have had damage? How many are running just fine?

[[_Silence_]]

I have an Ultra-D and a 20pin PSU. Running for some weeks with no probs, with 3500+ @ 3100Mhzs, rock stable.

[bachus_anonym]

Ultra-D here... I've been using two 20-pin PSUs with it so far: Fortron 530W and PC P&C 510W Deluxe... No stability issues whatsoever, running Winnie 2900MHz @ 1.85vcore/3.6-3.8vdimm

But I need to add, that I do not have any PCIe video card since I got it, about 2 months now I don't think it would matter that much in non-SLi configuration.

you really should not be using a 20pin DFI adamently suggests that you do not use adapters...

I was using an antec 380w before switching to the fortron. Ran 3.4v-3.5v vdimm with it also. Never really had any problems. I did see some voltage fluctuation under load, so that's why I got the fortron. No fluctuation now, but it didn't help me overclock any higher either.

Tested pcp&c 510w , Chieftec 360W and Enermax 550W, all 20pins..

No stability problems..

running 4000+ @ 2700MHz 1.64v and 3.6+vdimm

[thesaucier]

Please keep them comming. The reason is there has been a post on DFIstreet about running a 20 pin and damage done to memory. I have not seen this and would like to get as much feedback as possible. I am runing a 20 pin 600watt Enermax 36 amps on all rails. very stable and no problems. Have not realy started to heavy OC but running very stable at 2750 MHz.

[Pjotr]

Sounds like BS, or some fluke accident.

I run an old Enermax 365 350W PSU (18A@+12V), 20 pin (+ separate 4 pin) just fine. 1.5V CPU, 3.1V RAM.

[thesaucier]

Will it does not make that much sence to me other than a cheap 20 pin. I mean my 600 watt Enermax has more amps and power on any line than most if not all 24 pin power supplies do! I would like to use the 5v jumper to use more vdimm but this got me a tad nervous yet I dont know why??

[mdzcpa]

Not sure about the damage claim...that doesn't sound logical at all.

But, when it comes to stability at the high end, especially with SLI, a quality 24 pin PSU will get you further. That's already been proven countless times.

u dont need an adapter, a 20 pin plugs are backwards compatible with 24pin. I really dont get why the extra 4 pins are so important if one already has a nice powersupply. For ex if someone has a pcpower and cooling 510 deluxe why wouldnt it work even if it didnt have the extra 4 pins if u plug in all the extra connectors dfi has on the mobo wouldnt that make up for the loss of the 4 pins if the 4 pins are necessary?

Nope. I gained a significant level of stable overclockability when I moved from the PCP&C 510 to the PCP&C 510 SLI. Pretty much the same PSU except for the 4 pins. I picked up not only max CPU OC, but GPU OC as well. I discussed these results with Vivian at DFI and who concurred that a solid 24 pin PSU would yield the best overclocks.

Now, to qualify this, this was on my rig that had 2 6800U in SLI and an FX55 at 3.3Ghz that topped the ORB in February. So max clean power was key. Systems with less demand can get away with less PSU.

All this aside, DFI themselves STRONGLY recommend the 24 pin PSU. So, although its not a must, users who are maxmizing a high end rig may be leaving performance on the table.

Like I said in previous post, I ran 3.4v and 3.5v for over 2weeks 24/7 without any trouble. You have a much better psu than I was using, I would switch that jumper now

[ValkyrieLenneth]

I have SLI-D and Antec TC550 20pin, no Problem happened ^^

[GoodOmens]

How are you guys powering the PCI-E slots? Directly to the card? My card doesnt have a power connector ... I guess that means I need a 24PIN psu to power it?

[thesaucier]

Will this is good to hear and what I suspected as well. How many are running with the 5v jumper?

[gr8golf]

See my setup in the sig. Using a 20 pin with the 24 pin adapter. Will be getting a 2nd GT as soon as I can find where to buy a bridge. Guessing I'll have to upgrade my PS when I do, but I'll try to make my SilenX work.

[thesaucier]

Will this is very strange. Seems the post that was warning about using a 20 pin and damage to the memory that was a sticky on the DFIstreet forum was removed? Not sure why but seems strange. I did ask as several others did to give more detail and we got no further responce plus they pulled the sticky off. So I dont know. The more info here the better however!

[Soulburner]

Ok so I had the OCZ 600w coming for my DFI Ultra-D...now was that a bad idea?

There are some solution, a convertial cable, some modding or another 24 pin cheapy PSU just for the vga ^^

[enduracell]

I use my old trusty Antec 480 on the DFI ULRA D

The OCZ PowerStream 600W is a 24-pin PSU. You'll be fine.

Hope that helps =)

Ahh cool...I was under the impression it was a 20-pin but never bothered to look into it.

[conrad.maranan]

It's both: BTX 24-Pin and ATX 20-Pin. The extra 4-Pin cable snaps/slides onto the 20-Pin cable. Technically, it's still a 20-Pin PSU. You should still be fine, though.
