Old Fortron 500w for new ASUS P67 system

[Caden Fernandes]

I am already having a old Fortron 500w and I have built a new desktop machine for using at my home. It includes the ASUS P67 motherboard and the graphic card is AMD Radeon HD 6850 along with the 1 SSD and 2 HDDs. I want to ask you guys that would my Fortron 500w be enough for this gpu? I am looking forward to 4.2ghz overclock on the 2500k. What you guys say?

Despite the 500W power supply is nominally cannot deliver all that she 12V rails. yet building the optimistic assumption that two 12V rails can be completely loaded at a time (doubtful), you can organize your devices to properly balance the 12V rails (again unlikely) and that the seller was actually being honest (again, unfortunately unlikely) only 372W is available on the 12V rails.

UPM deteriorate very minimally. Things like "capacitor aging" are greatly exaggerated. All you have to worry about is making sure that the power supply is used in a reasonable condition and not subjected to temperatures too high. If you do that, a quality power supply should not have trouble keeping your total nominal production years. Many people do. And people, even more than that eventually upgrade your system with new components that significantly more energy than his previous set, and perhaps even less. It is narrow minded to assume that the requirements for a person to always increase with time, especially since today one of the trends in hardware design is increasing performance while decreasing energy consumption. Please. Obviously I'm talking about the UPM relatively modern, high quality, which means they have most of their rated power outputs available from the +12 V. This is 2011 not 2002.

As for his Vdrop censorship is a myth right? By the way what is the opposite of Vdrop? And a power supply lost something like 2% of its capacity to convert energy per year so if the power supply was 5 years that 10% or 500watt - 450watt 50watts = which is the core of whether supply was a 500watt 500watt in the first place and is not a 450watt in load testing which is a 400watt atm if it were 5 years old on the basis of this and the other thing.

My only point here is that it is wrong to say that a 750W power supply would be a smarter purchase. It would be more expensive while providing no benefit. As I have already said, my PC actually consumes a little more power than the proposed equipment OP, quite possibly in the order of twice. Yes, I would use a 750W power supply for my primary computer, but a completely different situation. I'm not saying that 750W power supply would be bad. I'm saying it would be unnecessary. You, however others have been implicated in several occasions that a good 500W power supply is insufficient and could create problems, it is not true at all.
