Firstly, here is my old thread which got closed I assume because I bumped my topic. (Topic) You can read it for a bit of background info on my current setup etc.
The gist of the old thread is just that I have a asus m2n-e non sli motherboard, which is old and only has pci e 1.0 I also have a geforce 7900 gs video card.
The card sucks basically, it works just fine for day to day things, but I'd like to be able to play the odd game here and there, not up to full spec of course but be able to play with a decent frame rate.
So the radeon 4870 was suggested to me, I really like the card, its not too overpowered for my system, like the 800 stream processors, like the gpu clock speed 256 bit etc. I also started looking the 5850 and 70 but decided they are too overpowered for my system.
Now my current psu is an enermax libety 500w (link to specs here: Link) I've looked at my psu, and there are 2 6 pin connections colored red, and labelled pci-e. 1 is in use on my current gpu.
Right now I have 2 HDD's plugged in (not setup in raid), 1 is my main HDD, the other I use every now and then to access a file or two. I also have 3 optical drives.
So what I'm wondering is will this psu be able to power the 4870? The 4870 lists a 450 watt psu as minimum, but I dont want to buy the card and have it not work in my system, then have to go and buy a new psu, hell I'll be like 2/5 of the way to building a new system if I did that.
Another thing is that my PSU lists that its able to run 2 cards in SLI.
Also, will the card include at least 1 6 pin cable, because I dont know where any of my spare parts are, they are probably in a box some where, and I believe this psu only came with 1 pci cable included anyhow.
My second concern is that this card has a reputation to overheat. I dont want to spend $100 and have a card that makes my system unstable...
I have a fan directly beside my gpu which looks like its main purpose is to cool any pci/pci e cards I have plugged in, here is a pic:
Does that look like it paired with the fan on the 4870 would stop any overheating from occurring?
So anyways, those are my 2 main concerns, my psu being able to power the card, and the card not overheating.
Your PSU will handle it fine. Usually you get a molex to PCIe adapter with the card. If your case is well ventilated and you clean the cooler on the card regularly (I clean mine every 3 to 4 months) heat should not be an issue.
It should be plug and play this way; remove current card in device manager, Shut down and physically replace card, Start up and install drivers for new card. IT is recommended to run driversweeper http://www.guru3d.com/category/driversweeper/ to get rid of any driver remains from the old card.
My PSU has 2 slots to plug in the power cable, but I only have 1 cable, I need to buy another one, I was unsure of what one to buy because it mentioned something on the box about only using the enermax pci cable to power pci components or you could cause damage.
So you lost one of them? Looking at your link its not clear to me if both PCIe plugs on are the same cable or not. I would assume no if the max output for the 12V rail is 32A. I know some of that is going to the ATX bundle, but if even half of that goes down the PCIe cable 16A seems like a lot for one cable.
I still don't understand the problem if you have two plugs, losing one is the only thing that makes sense right now. (I did just wake up...)
