Hi,
I am building a new PC by using some parts from my old computer and upgrading other ones. I am only upgrading my Motherboard, CPU and CPU cooler. All other parts are running on my current system.
I think I have everything worked out apart from the power supply. Ideally I wanted to keep my old power supply but have been told by a couple of people in this forum that I should change it. I have two questions:
a) Should I indeed get a new power supply?
b) If yes which one do you recommend?
Obviously budget is an issue here, as getting the power supply will take me above my budget. The specs of my new rig are below and I plan to overclock as I mainly use the PC for Gaming.
Thank you for your advise.

Thank you @Karadjgne you answered my question exactly regarding my older psu. Would you say 650W would be enough or even 550W (going for a 850W is above my budget)? I don't necessarily plan on going SLI as i usually just get a single more powerful gpu, but I will O/C my cpu. my gpu is already o/c'ed. I want to have a bit of room for more power hungry gpus in the future.
thank you.
thank you.
The psu is the single most important component of the pc, and too many ppl underestimate what happens with time. As components inside a psu get used, they start to deteriorate. In a cheap psu, you end up with 2nd, 3rd or even worse grade components and it's the worst and cheapest part that is often the first to fail.
Today's quality psus use Japanese solid caps, the best, etc so are comfortable with a 5yr warranty. They also have a better output ripple, very important for OC stability, and have no reasons why they shouldn't last at least the full 5 yrs.
Your current psu has already lost @ 5-10% of its ability and reliability, and it wasn't a quality unit to start with.
Reason it's such high wattage is its based on an older design that had need for high 3.3 and 5v outputs for the cpu usage. Modern motherboards have lost the Southbridge, and much of the functions are now part of the cpu, so the need for 3.3 and 5v has greatly diminished. This makes for lower wattage requirements with the gpu being the only really large draw, and thats mostly 12v
A modern 850w psu will power just about anything up to the most powerful gpus, in sli, and the new gtx 9 series just gut punched all that.

Rosewill Capstone 650M

High quality, has enough power for 650Ti in SLI & Overclocking as well.
Also, I agree with Teemi, A single better Gpu is better than 2 cheap cards in SLI.
