I'm trying to get a new AGP card over my GF 6800 128mb, so I can be good for another year before I upgrade to PCI-E. One problem, on the BFG site it states it requires "A minimum 400W system power supply (with 12V current rating of 20A or more)". My powersupply has 420W, but on the 12V it is only 13A. No idea what it means, but is being 8A short going to be a problem? This is my powersupply.
Anyone got an idea if I'm going to able to run the card on my powersupply? :?:
Yes, it's going to be a problem. That is a super cheap PSU, less than $20 on NewEgg. Make a good investment towards your new system and get a decent PSU. Otherwise, investing in the video card is a waste of money, and you're at risk of blowing not only the PSU, but other stuff, too. Look at the "sticky" in the power supply forum -- PSU 101.
Thanks. I think I should buy this so when I upgrade to PCI-e later on I can still use this power supply right?
It all depends what PCI-e card you are going to get. Also if you plan to buy a video card year from now different video cards will emerge and no one knows what the PSU requirements are going to be for a video card. You will probably have to buy a different PSU year from now. Thats how technology envolves.
Well I guess if i got a PCI-e system and something like a Geforce 8800GTX as an upgrade later on this power supply would work. It requires a PCI-e compliant power supply, 450W, and a combined 12V rating of 30A or more and that one fits the shoe. But then again I'm not sure if that would be for sure the card I would upgrade, so I guess I'll just worry about getting a PSU that will work for this card. Thanks everyone
FSP Group (Fortron Source) AX450-PN will be pleanty for the 7800gs but not 8800gtx. You are going to be looking for something more powerfull for 8800gtx. 8800gtx need around 33-36amps on +12V rails. If you plan to go with single 8800gtx these PSU's will be pleanty to power that card.
Hmm those might be a little more than I want to spend on a powersupply since I got to buy the card too. I suppose its better to just get a ~$50 one that will be good for this card now, since I don't even know exactly what I will upgrade to later on. Plus maybe they'll get cheaper as time goes on? Or does PSU price pretty much stay the same? Haven't noticed the pricing trend of PSU's.
I read the PSU reference thread and didn't see them mention Antec Basiq, so I don't know if its any good. I also saw a Thermaltake pure power 500W and have enough amps for the same price. Are either of them okay?
