I am trying not to bleed any more money on my old rig which is what I use for casual gaming. My old card crapped out on me and I picked up another card off of craigslist which is the ASUS EAH4870/2DI/1GD5 without realizing that my old power supply is a bit antiquated.
So I would like to know if it's possible to still power this card without issue with my current power supply.
My power supply is an Ultra 500W with the specs below. The PSU does not come with any PCI-e (6-pin) but I was thinking of getting a couple of the 2 molex -> PCI-e adapters to power the card.
Here is my thought, the HD 4870 requires 2 PCId (6pin). My PSU has 6 molex so I can take 4 of those and use the (molex to PCIe) adapters to get 2 PCIe. The other 2 molex would be to power the rest of my HDs and a CD rom.
AC Input: 115V/230V 10A/6A 60/50Hz DC Output: 500W (Max Combined Watts) +3.3V: 28A +5V: 30A +12V: 34A -12V: 0.8A -5V: 0.3A +5V: 2A Dimensions: 5.9' x 3.4' x 6.2'; 150mm x 86mm x 158mm Connectors: 1 x 20-Pin Power 1 x 6-Pin AUX (Xeon) Power 1 x 4-Pin 12V (P4) 6 x 4-Pin MOLEX 1 x SATA Power Y Adapter 1 x Floppy

Maybe. I am unfamiliar with the brand.
One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card with similar power requirements to yours, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.
Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.
Try it and see. I am a little doubtful because is is an old design - the 20 pin main power plug is a give away.
you should be fine, a 4850 runs fine on my 400W, so unless it's under 80% efficiency, it should be able to pull it just fine. But note that , that card would be seriously limited by your cpu. HAPPY GAMING
