Solved Do I need a new PSU when changing my graphic card?

Hi

I posted earlier about 2 graphic cards and I am going to get 1 tomorrow and I wanted to know whether I need a new PSU. I currently have a 450W PSU with a single +12V rail of 20A. I have been using this PSU since 7 years and the PSU is currently running fine with my 9400GT. The minimum PSU requirement for the GT630 from ASUS is 450W. The PSU requirements for my current 9400GT are 300W.

My current system is:
Intel Core 2 Duo E7400 @ 2.8Ghz
2GB DDR2 RAM (Single Module)
2 Optical Drives (DVD Super Drives)
1 SATA HDD 5200RPM
9400GT

Now I would be adding the following:

- Changing 9400GT for the 630GT by ASUS (NOTE: ASUS GT630 has PSU requirement of 450W while all other GT630 cards have PSU requirement of 350W)
- Adding another 2GB RAM
- Adding 1 more SATA HDD 7200RPM


So do I need another PSU because I have heard that PSU looses its output capacity over time.

✔ Best Answer
Most likely you will not need another PSU. That card pulls a max of 75 watts which comes from the motherboard. As riider has told you, that is a low end card.

You mean I'm fine with my PSU with all the upgrades mentioned above. Even after adding another Hard Drive?

Did you check the links?? Why are you adding another slow 5200RPM HDD? or did you mean 7200RPM?

Sorry I meant 7200PRM. I have a 5200 at the moment and I'm getting another 500GB Seagate 7200RPM.

Yeah I did check the link and it was really useful. So I'm going to go and get everything tomorrow. I was worried about whether I needed a new PSU because I didn't have enough money for a PSU and I am getting a new speaker system and I would have had to drop that for the PSU so now I'm relieved I can get everything :).

5VDC - 0.68A
12VDC - 0.55A
W = V x A

I still say you're wasting your money on the graphics upgrade.

Well I'm changing it for another reason which is the fan. The fan is making noises and is slowing down and I can't find another one to replace it. Here in Pakistan there are not much spare parts you can get like the small fans. If the fan dies you have to get a new card otherwise you don't have an option. Also I looked for a used 9400GT (same model but I was not able to find one) I was looking for it because I would have replaced my fan with the other one and keep my own card and then sell the other card with my fan as long as it was still running
