Asus HD 5850 power consumption question?

[CntrlAltDel]

Hi, I plan on buying an Asus HD 5850. I recently checked the system requirements for this card and it stated that I needed atleast a 550watt power supply and I'm currently running a Gigabyte Superb 550P 550W power supply which is running 3x hard drives and the obvious other main PC components.
I know that the card requires 2x 6-pin power connectors but my power supply only comes with one 6-pin connector labeled PCI-E, and I do know that I can find a molex to 6-pin but what I don't know is:
Is my PSU sufficient enough for this GPU?

Hi - there is one credible review of that PSU, it is awful:

you should read this, and tho you might be ok,
I wouldn't put a power hungry card like the 5850
with that PSU.

Damn, that's a big let down. But thanks for letting me know, I really thought I had a good PSU simply because of the brand and the cost.

Hey - you're not alone. I am on this forum cuzz I had a lousy PSU (& I selected it).

A lot of the respected brands for other things also have sh***y PSU's.

Stick with Seasonic, XFX, Antec, PC Power&Cooling, Rosewill Capstone series,
most Corsair's, most Enermax, Silverstone, & a few others.

I don't really plan to overclock with the GPU, shouldn't I use it either way?

Give it a try -might be OK, if I remember the review correctly,
it performed like a 450w unit. Also, you could consider a
less power hungry (but good performing) card, like
the 7770,650ti,etc.
