Using pcie power splitter on rx 6600 cards?

[Salamande]

Hi,

I got a couple of rx 6600 and really love them, they are running cool and trouble free and are very efficient (about 60w each, hiveos says lower, but let say 60w). Right now each cards have his own 8 pins pcie power cable, splitted to connect his own riser. This works flawless.

Only problem I have is it take a lot of pcie cable for the amount of watt really used. Only big PSU have more pcie cable.

I was thinking about using another splitter for the main pcie cable to run 2X rx6600, since they don't take that much juice.

So question is good idea or not?


Same question could apply to my rx 6700xt too, they use 2X pcie 8 pins each and are only using 100w, so problem is worse for the 6700xt.

How is it a problem when each cable goes to the card itself and the riser already? That's the best scenario for the setup and those cards, buy a bigger PSU if you need more connectors, don't be stupid.

I don't like answering this type of post but I do hope you make some corrections, what is the capability of this PSU that you are talking about? How much watt does this PSU have? How many rx6600 graphic cards are you trying to run? These are vital information that everyone needs to give you more accurate answer.

Do you have two power supplies available? Get Add2PSU
If your power supply is single but have less 6pins or 8pins get adapters online but make sure the POwer supply have enough wattage power to handle all the graphic cards.

There are alternatives like Antec's 'OC Link' as well, where you can connect two SP1000 or SP1300 units.

But personally, I like using a 400w ATX PSU to power the system parts, then power the video cards with HP or Dell server supplies. The server PSUs are always 80+ Gold or higher (90%+ on 240v @ 80% load), they're reliable, and they are cheap per watt. The only downside can be the 40mm screamer fan noise if you load the PSU at > 80%. So for the HP DPS-750RB, I keep it below 600 watts for max efficiency and low noise. It isn't louder than the video cards.

Rebooting isn't a problem if you power the ATX PSU with a smart Wi-Fi 120v outlet for no more than $15.
