Connecting the GTX 580 to the PSU with an adapter

[hr22]

Hello. I have an older computer for which I bought a used Asus GTX 580 graphics card, unfortunately I have a problem with connecting it, because my PSU Chieftec CFT-600-14CS is not able to handle 8+8. I would like to know if I can connect this card with an adapter? Unfortunately, I did not check the parameters of the power supply before buying this card.

I can't seem to find a Asus GTX 580 with 2x 8-pin connectors in the database. Can you confirm the connectors?

Anyways, I don't think it will be an issue but I am not positive. The 8-pin is just a 6-pin with a couple of extra ground connections, usually bonded directly to the same set of 6 wires.

This is this card:

ASUS GTX 580 DirectCU II Specs

NVIDIA GF110, 782 MHz, 512 Cores, 64 TMUs, 48 ROPs, 1536 MB GDDR5, 1002 MHz, 384 bit

Well, it says 1 6-pin and 1 8-pin. I think you will be ok attaching 2x 6 pin, or using an adapter.

Try attaching 2 6-pin connectors to it and see if it runs. the remaining two pins are ground and I in one test box just connected them to the PC case (well grounded)...

Thanks for the informations, but look how it looks, 8-pin and 8-pin:

Suggested PSU 550 W

Well, chieftec isn't the best performance-wise, but I think you can try it. I don't believe it'll gonna explode. No joking.

If you have a sticker on the outside of the PSU, it'll have the +12v rails and amps on those rails. That'll be how much max power it'll be able to supply the graphics card. As long as you have 25 or more amps on those rails, it should be fine for a gtx 580.

The sticker on the power supply:

Your PSU is showing 4 12v rails. The max 576w in the middle is total, which is more than enough power for graphics using 6 to 8 pin adapters, etc.

Yeah it's underpowered for his setup due to the current draw. Time to modernize the psu, that thing is over 12 years old by design.

Looking at that PSU label, I'd say you need 2 power adapters from 2x6 to 1x8-pin to safely match the max current the GTX 580 needs, otherwise your PSU might just turn off because of rail over-current protection kicking in.

Time to modernize the psu

Really anything modern made froma reputable company mid tier over the past 2 years should suffice.

Yeah, said more simply - connect four 6-pin cables from the PSU to the card's two 8-pin connectors (use adapters for the purpose).

who cares about DESIGN. 12 y.o. car engines are logically old by design. But they WORK. So as well as you don't care about that few MPG more than on new car, I don't see an excuse to drive new "eco"-cr@p than older and more reliable engine. As about PSU, this thing has plenty of power to run modern mid-range PC. If it's OK internally (capacitors etc.), why throw it away? The excuse for modernization is not the DESIGN, but "for safe sake" to be sure thing won't fuNk up ya new $$$-y hardware, or if you are fanatic (better to say lunatic) and will to pay for that new Nvidia proprietary BS connector lol

Bad analogy

Its about the current draw of a gtx580, the psu being the age it is cant keep up and is under capacity.

lmfao the 580 isn't way better in terms of "age" than this PSU. So the purchase of new PSU purely bcuz of GTX 580 is pure money waste. Better to change GPU for newer card (might be used of cuz). I personally won't use today anything older than GTX 700 series (better 900) or AMD RX 500 series.

The PSU is fine - you need to tweak the cables and card a bit - undervolt it. And connect as advised above - use more cables to split the load and not call the current protection.

This is a common issue - the older PSUs had their load divided to more than one rail, while the modern PSUs carry it on one rail.

could this dynosaur (GTX 580) be UV tho?

 

[freeagent]

Both of my 580s are dual 8 pins. These things draw hella power.. don’t mess around.

Edit:

My X58 setup would ruin 850w psus every couple of years.

Should be, use MSI Afterburner to check.
I see from the comments that the voltage can be set as low as 0.963 V.

Thank you all for your posts, for your involvement in my topic. I decided to return the graphics card, I agreed with the seller, who gave me the opportunity to return this graphics card. I bought Asus GTX 570 (2x 6-pin), I waiting for delivery.

Thanks for your help.

You ain't telling me anything new there FARq

I've tried AB with some old cards even 10 series and sometimes it was a no-no in voltage section lol
