RX 480/470 will work on 6 pin to 8 pin or molex to 8 pin safe ?

[Strangerbob]

hello everyone my psu is rs-500-pcar-i3 (cooler master )
i know that my psu have only 6 pin x 1 can someone help ? i was going to buy rx 480 from msi and if i got the adapter 6 pin to 8 pin safe i will be safe to the system

The reference Rx 480 work with 6 pin , custom cards need 8 pin.

6-pin to 8-pin is not safe. The amount of current pulled by an 8-pin connector exceeds the rating of a 6-pin connector and cable.

 

[Rogue Leader]

Only the reference RX 480 GPUs work on a 6 pin connector. Adaptors are bad news, if the PSU doesn't have a n 8 pin connector its not designed to deliver that much power by that connector. You should replace your PSU if you do not buy a 6 pin RX 480

 

[Strangerbob]

the only way is to change the psu ?

 

[weberdarren97]

I just looked up your power supply, it's an Extreme Power Plus model. Very low quality. Please replace it with a higher quality unit.

 

[Strangerbob]

which brand do you prefer for that card and my cpu is i5 6600

 

[Rogue Leader]

If you are on a budget look for the Corsair CX450M. It pairs very well with your system and an RX 480. More than enough.

 

[weberdarren97]

The SeaSonic M12ii 620 is slightly more budget friendly, while still being above acceptable quality.

6-pin to 8-pin is not safe. The amount of current pulled by an 8-pin connector exceeds the rating of a 6-pin connector and cable.

#20 cable (the gauge typically used in the cheapest PSUs) is able to safely carry 11A per wire (ventilated enclosure rating) and standard MiniFitJr pins are rated at 9A each as well. A single wire and pin pair is perfectly capable to safely provide ~108W and a 6-pin connector has at least two active power pin pairs. (The third ground and 12V pins may be used for remote voltage sensing and connector detection) for a combined total of ~216W before exceeding the wiring and connector's real ratings.

Where the real problem lies is whether the PSU is actually capable of reliably delivering over 150W over those wires and the lack of native 8-pin PCIe power cables is implied to mean 'no'. Electrically speaking, the 8-pin connector does absolutely nothing to improve the cables' power delivery since all it adds is two extra ground pins which serve no purpose other than letting the load know that it has an 8-pin power cable plugged in instead of a 6-pin one.

im not good with computers you mean its bad idea to get the cable right ?

 

[Strangerbob]

guys what about gtx 1060 it needs 6 pin according to http://www.realhardtechx.com/index_archivos/Page362.htm ?

 

[Rogue Leader]

Yes he means its a bad idea to get the cable.

There are SOME GTX 1060 models that have a 6 pin, some do require 8 pin as well. An RX 480 will work too, but only the reference models that has a 6 pin such as this style

Otherwise most have an 8 pin.

No matter what replacing your PSU is preferable its pretty low quality, however either of the above will work without an adaptor.

Correct. Unless you are confident in your PSU's quality, don't use adapters to connect your PSU to things it may not have been designed for.

even molex to 8 pin wont work ?
and also like for rx 470 or gtx 1060

i found some gtx 1060 with 6 pin should i go for it ?

im not going to overclock any of those

Do not use adaptors. If the PSU didn't come with the connector it can't properly handle it.

If you can get a GTX 1060, RX 470 or RX 480 with a 6 pin they will work.

We are saying we highly recommend replacing the PSU, but if you insist on using it only use a card that has a 6 pin.
