How can i tell if a PSU is good or bad?

Okay i just want to know how i can know if a PSU is good or bad. I know that Corsair, Silverstone, Antec... Makes great PSUs but what is the diffrent between a good 500W psu and a bad 500W psu : )?


I currently run almost unknown brand named "Titan" i don't remember the model of it. (im not home this weekend) and i can't even find it on google o.0... it says output is max 560w.. but i have no idea if it's "Good" or "Bad"

I am thinking of upgrading my CPU to a AMD Phenom II 1055T because my CPU bottlenecks the GPU in almost any game i play.. i was thinking about overclocking the 1055T to the highest clock speed i can reach with the NorthQ 3580 cpu cooler.. but im really not sure if my psu can handle it.. im not even sure if it can handle my current system /:


System at the moment:

Asus M4A78 Pro Am2+
AMD Phenom 8400 x3 @ 2.52 Ghz
ATi 4870 1Gb 800/1080
2x 320GB Raid0 sata hdds
1x 500GB IDE hdd
1x DVD/RW drive
1x 120mm fan
2x 80mm fans
NorthQ 3580 watercooler with 120mm fan.

well the best way to find out the difference is to look through reviews.

all do a good job on PSU reviews.

cheaper PSU also tend to rate their power as peak rather then continuous. they will skip out on 12v power that powers your CPU & GPU. they also test their PSU in cooler temps like 20-30c rather then warmer and realistic temps 40c+.

these articles can help you along with any reviews you find.

Yes there is good watts and bad watts sort o speak. The better psu companies do a better job with efficiency, as well as stability, especially when a particular psu is under heavy load and the temperature of the unit rises. Lower end psu's just can't hold a candle to overall stability, and consistency of electrical current under load and temperature increases.
