Questionable voltage should I upgrade?

post #1 of 2
Thread Starter 
Ok I have the following power supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817814005 .

I have a the following in my case:

Q6600@3.38
Asus GTX 570
5xLED 120mm
1xRaptor 150
2xWestern 1 TB
I have the DFI LP UT P35 board
4 gigs ddr2

Want to eventually move to IVY Bridge.

Right now when I look at my voltage its off. My 12v is showing at like 11.7. My other ones are all showing at .2-.5 lower then what they are. Now is that within specs or should I get a new power supply?

I would like to note I have had that power supply for a very long time wish I could just buy it again or newer model but it doesnt seem like the tagan brand is around anymore.

Never trust voltage reading from software or BIOS. If you want accurate voltage reading get a multimeter. +12 V on yellow wire, +5 V on red wire, and + 3.3 V on orange wire. Black wire is ground.

That said, the PSU you currently have is not so good in my opinion. It has problem when it comes to ripple suppression. Here is a review on its older brother, 1300 W version,

I do recommend getting a better PSU. You can look into Rosewill Capstone families (550 W or 650 W). Seasonic M12-II 520 W. Or a PSU from this list,
