Molex to PCI Express adapter

[Thermalk]

Hey I got a question, I'm going to upgrade my computer soon and I'd like to keep my PSU but the thingis, it only has 1 PCI express connector. The PSU is a OCZ stealth Stream at 500W, I do have 2 MOLEX plug that are somewhat free, the 2 of em only have 2 fans connected to each one of em. would it be safe to use an adapter like this one LOGISYS AD201 12v Molex to 12V 6Pin Adapter;

to make that extra PCI plug my new card is going to need?

Here's what I'm planning to get;
Motherboard: ASUS P5QL PRO

CPU: Intel Core 2 Duo E8400 Wolfdale
http://www.newegg.ca/Product/Product.aspx?Item=N82E16819115037
RAM: G.SKILL 4GB (2 x 2GB)

Video card: MSI N260GTX-T2D896 OC

PS: Is the PSU even good enough for all that, I'm not sure about that.
Thanks for reading.

Yes, that will be fine.
You don't have to buy it. It comes with the new video card.

The power supply is fine as long as it has 35 amps on the 12v rails.

Hey thanks for the info, i checked the manual and it says for each +12V rail, the maximum load is 18 amps so it bring it to 36 for both rails.
Is that what you meant when you said at least 35 amps, it's 35 amps combined right?

 

[evongugg]

It's actually 40 amps combined max power.
It's fine.

even 'if' they dont come with it, you can get one off ebay for not a lot.

Great, that'll save me a couple of bucks.
Thanks again.
