Will this psu last until I upgrade?

post #1 of 7
Thread Starter 
I currently have a 500W psu with 20A on the +12V rail. Will this support a 3500+ with a 7800GT until I get an antec true power psu in the next two months?

Hard to say, ratings aren't regulated at all. That could be peak output at 5 degrees Celsius. Bottomline is that it might hold up, but it also might not. Keep in mind that you're risking any parts that you hook up to it. When power supplies blow, they usually take other devices down with them. Your call...

I once had a 450W psu with 18A on the +12v rail blow when connected to a 3.0 prescott and a 6600gt but thank god it was only the psu that blew.

maybe it'll run with everything on stock... but be carefull because it can melt and cause other damage to hardware

Just A Quick Question Though Why Dont Vga Card Manufacturers In Their Minimum Specs For A Card Say Only The Necessary Wattage And Not The Amperage And Wattage?
post #6 of 7
well it's hard to say why they don't give more information. in the same regards mobo manufactures are often vague about what the power requirements will be as well. They leave it up to the customers to find out that their psu won't work with their mobo... oh well.

well, my honest opinion is that if you have to ask if it will work then you already know the answer. 20a on the 12v rail is like nothing. What else do you have in your case? if you only have a couple fans and a single optical drive it might work... but if you're pushing anything else I'd say your best bet is to not try it. If you blow your psu you run the risk of it sending a surge and killing the rest of your system. hopefully nothing like that would happen... but really... why risk it? Your best bet is to upgrade psu and gfx at the same time.

From my understanding the 7800 loves power. Why gamble with a cheap PSU.Take your time and get a PSU that you know will handle your setup. I would think you would need a PSU the puts out over 32 on the 12volt rail
