A question about adapters

Octavious · 2024-08-10T16:10:30+0100

I have a Z230 workstation, an RX 570 graphics card, and an additional EVGA 500W power supply that I'm not currently using. Would it be better to use a 6-pin to 8-pin adapter to run the card on the workstation's existing power supply, or should I install the EVGA power supply, which has an 8-pin connector, and use a 24-pin to 18-pin adapter to connect it to the motherboard? What are the risks, and what would be the best solution?

Your motherboard uses an 18-pin connector?

Rafael.luc · 2024-08-10T16:57:39+0100

RX 570 has high consumption and greater than 150W (TDP), better to use the EVGA 500W power supply with appropriate cable for 8 Pin GPU.

You didn't describe the existing PSU. If it's the stock 320 watt POS, I'm surprised it still works.
From what I can see it looks like it might be a non standard size. 18 pin board sounds strange - the normal connector is 20+4.
I'd try to use the EVGA PSU, but I'd MAKE SURE you're not dealing with some weird non-standard HP BS.
Get the motherboard manual, or some pics of the connectors in question and the sticker on the PSU might help.
Good luck!

Yeah.

I'll need to use a 24-pin to 18-pin adapter to connect the power supply to the motherboard to do so.

The power supply in the Z230 workstation is 400W with an 18-pin connector for the motherboard and a 6-pin connector for the graphics card. I believe it will work well with the RX 570, but I'm wondering which option is better: getting a 6-pin to 8-pin adapter and running the RX 570 on the original power supply, or installing the EVGA power supply, which would require me to get an 18-pin to 24-pin adapter to connect it to the motherboard.

You should be fine with a 6pin to 8pin for the GPU. RX 570 isn't that bad of a power hog. Delta is a high quality manufacturer.

Sim.

Para isso, precisarei usar um adaptador de 24 pinos para 18 pinos para conectar a fonte de alimentação à placa-mãe.

A fonte de alimentação na estação de trabalho Z230 é de 400 W com um conector de 18 pinos para a placa-mãe e um conector de 6 pinos para a placa de vídeo. Acredito que funcionará bem com a RX 570, mas estou pensando qual opção é melhor: obter um adaptador de 6 pinos para 8 pinos e executar a RX 570 na fonte de alimentação original ou instalar a fonte de alimentação EVGA, o que exigiria que eu obtivesse um adaptador de 18 pinos para 24 pinos para conectá-la à placa-mãe.

6P 75W theoretical, 8P 150W theoretical. Better you adapter for motherboard.

I have 3 RX 570-4G that I used for mining and I was surprised by the consumption at the outlet when testing at maximum load on these cards.

Yeah, but I can also use an EVGA 500W power supply, which would give me the 8-pin connector directly. I'm not currently using this power supply for anything else, but I'm asking which option is less risky: using an adapter for the graphics card while keeping the original power supply of the case, or using the EVGA power supply with an adapter to connect it to the motherboard?

I guess both would be fine.

But 8-pin just adds a sense and a ground pin which allows more power. The cable is still a 6-pin.

I wouldn't use adapters for let's say, my RTX 3080, but a card like RX 570 isn't hard to run.

What are the risks of using a 24-pin to 18-pin adapter to connect the EVGA power supply to the motherboard? I used the same power supply in a Dell Optiplex 7020, which requires an 8-pin connection for the motherboard, so I used a 24-pin to 8-pin adapter for two years. However, I eventually encountered some issues with the motherboard, which stopped working. I had to buy the Z230, and now I'm not sure if the problem was caused by the adapter or not. That's why I'm considering both options: either using a motherboard adapter again or just using a 6-pin to 8-pin adapter for the graphics card. I don't know which option would be safer.

What would be the safest option to do, considering that during heavy gaming, the temperature of the graphics card exceeds 80°C and remains stable between 80°C and 85°C? At the same time, I don't want to risk damaging the motherboard or the graphics card if I use an adapter for either of them.

Just use the EVGA one with the motherboard power adapter then if you are worried.

Will everything be safe?

That's a 12V supply, the EVGA will not have 12V standby

Seems the converter cable includes a 5Vsb - 12Vsb converter

ty_ger · 2024-08-10T19:26:01+0100

I would use the 6-pin to 8-pin adapter on the GPU. I think it is less likely to cause a problem; especially considering 6-pin PCI-E connectors are massively under-rated compared to what they are generally capable of.

Indeed, the EVGA has no 12V standby

Frick · 2024-08-10T19:49:00+0100

I'd trust the PSU in the workstation more than that EVGA unit. It'll be fine. Depending a bit on how many harddrives and other controllers you have.

Not possible to use the 12V rail, maybe current is too high?

The safest adapter is the 24 > 18 V adapter since it has an auxiliary connector to power the CPU. But another user reported the +12 V standby.
I would remove this 6P cable and place another 8P cable by soldering directly to the 400W power supply PCB.

If you do this, choose a yellow/black cable to avoid confusion.

Octavious · 2024-08-10T21:23:52+0100

Can someone explain to me the issue with the EVGA power supply in simple terms? Because I don't understand things related to electricity.

It would be difficult for me to do that because I've never worked with the inside of a power supply before.

Shrek · 2024-08-10T21:50:08+0100

Looks like the EVGA supply will work for you with the converter cable.

I had not realized initially that

The original supply is 12V only
The converter cable includes a 5Vsb to 12Vsb conversion

I will look for the specifications of your 400W power supply.

The approximate consumption I measured on an RX 570 and Power Supply was an EVGA 450 Bronze (+- 85% efficiency at 127V)

180 W measured at the wall socket Full Load

-27W Due to the efficiency of the PSU, +- 26W coming from PCI express

180W - 27W - 26W = +- 127 W for the cable (10.6 A)

Octavious · 2024-08-10T22:14:40+0100

It seems we've sparked a debate about whether the EVGA power supply will work or not. But since we've agreed that it can be used, what would be better now: using it with a 24-pin to 18-pin adapter, or using the Z230's power supply with just an adapter for the graphics card?

Bro you are making it harder for me because I don't understand electrical stuff

I say the current PSU with an adapter for the graphics card. The reason for this is that that specific EVGA PSU is bottom tier stuff, and that the PSU for the workstation is likely* of higher quality. It'll be fine, the RX570 isn't a power monster and as long as you don't have like dozen+ hard drives or something connected to it it will be just fine for the RX570.

*I say "likely"because Delta Electronics makes some high end stuff, but they also manufacture stuff to whatever specifications their customers are giving them so there's no way of knowing how good that specific power supply is without looking at the components inside and test it properly. Add to this that it's about ten years old at this point.
