I just want to know what is the meaning of 80+ at the PSU body?and what effect 80+ PSU and non 80+ for PC performance?oh yes and the last one what is the meaning bronze,silver,gold and platinum modular?Im a amateur :)  maybe this thread looks funny but i really need the answers

80+ means its maximum efficiency is over 80% bronze, silver, etc all mean higher efficiency again.

80+, including the bronze, silver, gold etc. only look at the efficiency of the power supply, not the quality.

A modular power supply is a separate feature - it means you can detach cables that are not in use from the power supply, so there will be fewer cables inside the system. Modular also does not say anything about the quality of the power supply.

The quality of the power supply is what determines whether the power supply can, in the worst case scenario, cause damage to the PC components. The best way to find out the quality of a power supply is to look for reviews from reputable sites like Hardwaresecrets, HardOCP, Jonnyguru and TechPowerUp.
If you can't find reviews, then you should at least go for reputable power supply brands like Antec, Corsair, Seasonic, and XFX.

The 80+ certification also includes tests to see whether the voltages are well controlled etc too. Non certified power supply units (psu's) are not recommended for that reason. And we get lots of problems on this forum with non-certified psu's.

80+ certification does not really guard against poor quality. This article explains it well.

That's a pretty synical article. Maybe put another way - better have 80+ cert than none on what you buy. Not everyone cheats. Stick with Seasonic and other high end independently reviewed psu's as recommended by http://www.tomshardware.com/answers/id-1804779/power-su...

i'm not really sure about my friend answer...he said the 80+ modular psu can longer life your cpu component cuz the electricity from the modular psu is have a good quality and also the 80+ modular psu can stabilize your electricity into your cpu

Some psu's control the power coming in better than others. Most psu's work from 100V to 250V, so they have to control the voltage.

They all control the output voltages - 12v, 5v and 3.3v, but some worse than others.

http://www.tomshardware.com/answers/id-1804779/power-su... shows good psu's and bad psu's - as found by testing by other people eg RealHardTech, Tom's, etc etc.

JonnyGuru and Hardware Secrets do good PSU reviews, Tom's are lacking... You can find most PSU reviews linked to from this site
http://www.realhardtechx.com/index_archivos/Page541.htm

All 80+ really cares about as far as quality is that it could do what it said on the label and the voltages didn't go out of spec. ATX spec is pretty loose, +/- 5% on the main rails, thats 11.4-12.6V on the 12V rail. How well the voltages are regulated is dependent upon the internals of the PSU, there are some 80+ bronze units that have fantastic Vreg, there are some 80+ platinum units with average Vreg. Being 80+ platinum and modular doesn't mean its a better unit, it means it is a more efficient unit. There are many top end 80+ platinum units, but there are many that are only notable for their efficiency.

Also, that article from HardOCP may be a bit cynical, but i agree with it, and i hate the delusion people have that 80+ will save them money, you aren't who it was aimed at!
