Powering my R9 270X with one PCIE 6-pin and a dual molex to PCIE 6-pin?

I need help with powering my XFX R9 270X. I have a Raidmax 530W PSU, and it came with a red PCIE 6-pin connector. It also came with an adapter of PCIE 6-pin to 2 PCIE 6-pins + 2 PCIE 2-pin add ons. So naturally, I connected that adapter and plugged in the 2 6-pin PCIE plugs. I have been using my newly built computer for several hours (still working on setting it up, haven't done any gaming yet) and the fans on the GPU work. However, I just noticed in the manual now that it says to NOT use an adapter from 1 PCIE 6-pin to 2 PCIE 6-pins. So I found that they have a couple 2 molex to 1 PCIE adapters. I read on somewhere on Tom's Hardware not to use molex adapters for your graphics card, because they aren't meant to supply that much power or something...

So what setup should I use? I was thinking maybe the PCIE to dual PCIE adapter to plug into only ONE of the 6-pin PCIE slots (without the adapter, the single PCIE isn't long enough), and to use one of the 2 molex to single PCIE for the other connector. Is this okay to do? I don't want to damage my card, and I want it to function properly.


Help is much appreciated, thanks

Using the molex to 6pin should be fine. But I'm slightly worried about the power supply.

Agreed, Raidmax only makes tier 5 PSUs: http://www.tomshardware.co.uk/answers/id-1804779/power-...

Tier five - Replace immediately. These units are NOT recommended for any system, no matter the purpose. Reference to higher tiered models for a better and potentially money-saving unit

Okay, thank you for your advice. I can return it for free to newegg and get a different one. I am looking to save money, I originally bought the raidmax for $35 and am looking to spend around the same amount (I can do rebates). What do you think of these two?

Get the EVGA 500B bronze if you're on that tight of a budget. It would be better to spend more money and get something of a higher quality.

Once again, agreed. That PSU will be sufficient if you simply can't go over the budget, but this would be much, much better: http://pcpartpicker.com/part/xfx-power-supply-p1550sxxb...
