I have a 600w PSU from OCZ, Nvidia says the GTX 480 requires minimum of a 600w power supply. When I check on the website hwcompare.com it says the GTX 480 uses 250w. My current graphics card which is a GTX 550ti uses 116w.
Would my 600w PSU be enough for the GTX 480? I only have 1 hard drive running and 5 fans, I have an Apevia X trooper case. My Intel core i5 uses 95w.
Is there a program that shows how many watts the PSU is running? (I figured I could run my PC on heavy load and get the number of watts it has left, then subtract 116 and then add 250, am I correct?)
I would say 600 is the min suggested supply for a GTX480(no OC). This usually takes into account that many people do not have quality psus. Apevia is not a great psu - I would reccomend an Antec, Seasonic, Corsair, Silverston, XFX....
As has been said, the important stat on the PSU is how many amps on the 12v rail. If you list your exact PSU model, we can give you a more accurate answer.
Also, is there any particular reason you're interested in the GTX 480? It's a bit old, and as a result, is incredibly inefficient by today's standards. If your PSU can't handle the 480, there are certainly more powerful cards that it can handle, simply because they make better use of that power.
I was going to answer this but figured I would wait to see if recon-uk would post first.
What he dosent know about the 480 isn't worth knowing.
Having said that....
Please for the love of god select him as best answer so they can close the thread before he starts posting video's of his 480 on here again.
Filled everything out correctly and it currently says Recommended PSU Wattage: 460
I add in the GTX 480 and it says: 592w recommended (542 min.)
I understand these are just estimates but since the estimates are EXTREMELY close to 600w, so are you sure I would be fine?
You can always save the old PSU to recycle in a later build. I upgraded from a perfectly good 550W Antec unit to a 650W Seasonic unit recently, largely because it was a great deal on Newegg and the efficiency is hard to beat (Seasonic X650 Gold, pretty much the best 650W unit on the planet).
The Antec is now my backup unit, and I'm actually considering pulling all my spare parts together for an HTPC since I now have a bit of everything lying around.
