Can I use a 2xmolex to 6 pin and 2x6 to 6+2 pin to power a R9 280X ASUS DCUII TOP

[DistortionGamer]

So here's my PSU:
Nox 620W (pretty sure it has single 12v rail)

And as you can see it only has 2x6pin and no 8pin connectors.
I heard that the 8pin deliveres 150W and the 6pin do 75, so I would need the 2 I have just to cover the 8pin requirement for the card, can I use a molex to adapter 6pin for the remaining slot, or do I need 2 molex to 6pin?

+5V - 24A / +3.3V - 24A / +12V - 48A / -12V - 0.8A / +5VSB - 2.5A

One molex to 6 pin is fine, some cards even come bundled with such adapters.

Yeah but everyone keeps telling me that if my PSU doesn't have any 6+2pin connectors, that it's a huge risk to use adapter and that I might burn out my system.
Basically these are the replies I get to this question:
"1. You can use a 8 pin => 2 x 6 pin
2. A single 6 pin connector / cable should never have 150 watts of power going thru it.
3. While, "theoretically, two molex can power a 6 pin. I do not recommend molex connectors ever be used in any way, shape or form with PCI-E connectors."

or

"You're asking for trouble. The fact its missing those connectors is a huge red flag that they don't really expect someone to power a good GPU with it."

or

"You're asking for a house fire doing that with that PSU. Get yourself a Seasonic, XFX, EVGA, etc."

or

"If your unit does not have the required connectors that is a very good sign it is not up to the task of running the card.
Never use adapters, they are not "safe". My recommendation, get a new unit."

etc...

Problem is I can't afford a new PSU right now :/

Your power supply has enough amps to power a single 280x graphics card without any issues. But get instead a similar 6 pin to 8 pin adapter to properly connect your card. I don't see any complication here.

Your PSU is fine.

Your PSU is fine.

Is this adapter equivalent to the one you posted? (asking because the store is right next to my house)

I heard that 6+2pin connectors transfered (probably not the right term...) 150W and the 6pin only 75W. Hence why I asked wether I should I use 2x6pin to 6+2pin. People keep saying never to run 150W through a 6pin connector :/

It looks fine. Just monitor it carefully in the beginning, if it gets too hot, then I would replace it.

Your 6-pin PSU cable has actually three 12V wires (same as the 8-pin cable) capable of delivering >150w. Safely. Sure, the native 8-pin cable does support more current due to having an extra ground wire or two, but is it twice as capable? Not really. Point being, the wires won't be a limitation in your particular case unless you will be trying to break overclocking records and/or running Furmark day and night.

In your case, is fine to do this.

Would not be good to transform one 6-pin power conector in a 8-pin, then use with the other conection a molex to 6-pin and a 6-pin to 8-pin in cascade.

All right guys thanks. Put my mind to rest since I really didn't have the budget for a new PSU

Another thing to put your mind to rest: the card is pulling the power it needs through the wires. It won't pull more than it needs.

So the wires won't act like little fire hoses to push power to the card - so they won't be pushing excessive power that causes problems or anything. Instead, it's the card that sucks power through the wires like a straw. You just want the wires to be beefy enough to support the card, which is fine here.

Alrighty then. Thanks man
