PSU good enough for 2 6pin PCI-E connectors?

I am using a nVidia GeForce 9800 GTX+. My old one died, so I got another. Old one had a single 6pin PCI-E connector. This one has 2 power plugs, which is new to me.

My power supply only has 1 6pin connector, and plenty of empty molex connetors (4 pin). I saw that you can get a 2 molex to 1 6pin adapter, it was discussion on these forums. The question asked of that thread was details on the power supply, to see if it could handle it.

I don't know much about power supplies, but here is the information on mine.
Orion HP400D. 400W max.
+3.3V (30A)
+5V (28A)
+12V1 (14A)
+12V2 (15A)
-12V (1A)
+5sb (2A)

I don't know what these ratings mean, so I am unable to tell if my power supply can handle this, or if I need a new power supply.

Can anyone help shed on light on this issue? Thanks in advance for any help you can provide.

It is on the low end for the card but if the old card ran this one should unless it was a contributor to the failure! Did you experience any instability?
New one with 2 PCIe power connectors is not a bad idea!

Old card (still 9800 gtx) only had 1 pin connector, instead of two. Not sure why the same card model has two different builds, but...

The old card ran fine for 4 years. Never had instability, nor any other problems.

So adding a 2 molex to 1-6pin should work? (Along with the built in 6pin)?

Thanks! I'll pick one up tomorrow. As for a longer term solution, do you know of any power supplies that will work (without being the best, hence expensive)? I looked up higher watt (500W) supplies, but they had only 1-6pin connector. They may not have been good supplies, or I suppose they could have been old. I wouldn't mind a higher wattage just so I can expand in the future, however I wouldn't be expecting to expand much for a few years (still runs most games on high settings with no lag or slow frames, so no reason to).

Or if that is too vague and general, are there certain brand names to look for?

Thanks rolli59! I picked up the Corsair for $35 ($10 off, plus 10% off deal which ends in 2 days, which is $6, plus $20 rebate which ends today.) Couldn't ask for a better price. Thanks both for your initial help and your suggested items. Have a great day!
