BFG 550 question

post #1 of 4
Thread Starter 
Bought this power supply almost 2 years ago before BFG went bust. My question is, it appears to have 2 12v rails at 18A each. Would I be able to run a Nvidia 560 GTX Ti which says it requires a 500watt supply, and 30A on the 12v? 18 + 18 only is 36A, do they allow for other draw on the line or does the GPU itself need 30A?

I'd love to upgrade the supply, but the money will be tight enough for the card, so if this supply wont do it, I'll have to find a less hungry upgrade.

Thanks guys.

You'll be fine with that PSU with that graphics card. 432W on the 12V is plenty. They say it requires 500W because there are so many companies that make 250-300W PSU's and rate them as 500. I wouldn't necessarily recommend it cause that thing is getting kinda old but I bet you it could power a 580 if you didn't do any overclocking. What you should do, is take out the power supply and crack it open since you don't have to worry about the warranty, and clean it with some dust off. They get really dusty in there and just spraying through the back or fan doesn't get much of it. Heat is really bad for PSU's....especially that PSU since it has caps rating @ 85C

Thanks a ton, your really informative on this supply! I keep it pretty clean, and use compressed air to blow out the dust bunnies. This supply seems to blow out of the case, and I have filters on the intake. The fan is massive so you have pretty good access to the dirt without opening it up, and the whole back is vented so it has a place to blow the junk.

Appreciate the help!
