I am getting a Galaxy GTX 460 1GB this Christmas and I'm wondering if it is ok to run it with an adapter...

The case I own has a built in 500watt power supply and it only has 1 PCI-e connector...

--->http://www.newegg.com/Product/Product.aspx?Item=N82E16811147081

(Yes I know I need to upgrade my PSU but I hit my budget...Waiting till march to get my new one)

If I use an adapter will it hurt my system or the GPU?

The GTX 460 will draw a maximum of 13.3 Amps (assuming the graphics card is not overclocked) from the +12 Volt rail(s). The power supply unit that was included in your Rosewill R519-BK case is able to provide 20 Amps on each of the two +12 Volt rails. You shouldn't have a problem using a molex to PCI-E adapter.

Thank you for your help.

I can't find any info on that PSU, other then it was made by Deer. In two words, not good.

While I doubt that one is your PSU, it shows what Deer can do. I also severally doubt you have 20A X 2 =40A available on your 12V rail.

I've seen a couple of different specs for the power supply that was included in the Rosewill R519-BK.

The following, that I just saw, is from Rosewill Inc.'s own website for the R519-BK :

Connector:
1 x 20+4Pin Main Connector
1 x 4Pin & 8pin ATX12V Connector
4 x 5Pin SATA Connector
2 x 4Pin Peripheral Connector (Quick-release)
1 x 4Pin Floppy Connector
1 x 6Pin PCI-Express Connector

Output: 500W Max.
+3.3V@22A, +5V@16A, +12V1@15A, +12V2@16A, -12V@0.8A, +5VSB@2.5A

Certified:
UL, CSA, FCC, CE, CB

The above spec shows lower current ratings on the +12 Volt rails than in the other specs I've seen.

I also see this on Rosewill's website for this R519-BK case:
Power Supply : 500W(Model:D R-8500BTX) <--- This is a DEER model number
Output +3.3V@24A,+5V@24A,+12V@41A,-12V@0.5A, +5Vsb@2.5A

Yes, Deer has very questionable reliability.

I don't think I was very clear in my post. I would use the adapter, but change the PSU ASAP. And I mean very soon. So soon in fact that if you can't do it without about 3 or so months after getting the GPU, don't get the GPU. I would hate for the PSU to blow and take out all my stuff.
