What you read this with ?

never trust motherboard/software reading for this, get a multimeter and read it on a molex or a PCIe 6pin cable. ( yellow are 12v )

I used a "Thurmaltake Psu Tester"

What i what to know Is the 11.2 reading To low or not

This is the ATX spec.
+12 VDC ±5% (±0.60 V)
+11.40 V to +12.60 V

I dont know if i trust your Thermaltake tester ... you have a real multimeter on hand ?

A yellow and a black on 12v DC with the multimeter.

no i don't I spent more than a good multimeter on the psu tester

Mostly to validate if this thermaltake tester give good reading

ok lets asume the readings are right what should i do?

Simple : Contact thermaltake since you are using both their PSU and tester

I have the Thermaltake tester, I reviewed it here: http://www.funkykit.com/component/c...eview-thermaltake-dr-power-ii-psu-tester.html

I found it to be decently accurate. 11.2v on the 12V rail is outside spec (11.4 to 12.6), so officially speaking that PSU is dead.

What model/wattage/year(roughly) PSU is it, anyway?

I'd warranty that PSU and/or buy a new one.
