Upgrading PSU

[Leibow5]

I currently have a Thermaltake tr2 600w psu. It does not have an 80 plus proficiency. Should I buy a better psu with 80 plus proficiency or does it not matter.

Can I have the specs of your pc to see if you need a 80+ certified psu?

I think it'll be fine,your system would pull maybe slightly more than 50% at full load.

77 - max power consumption 3570K

164 - max power consumption 660 ti

add around 50 watts for everything else,almost never actually uses 50 watts.

so your system should be somewhere between 291-325 watts at full load.and I say 291-325 because it's my rough est. - 50% of psu rating.I highly doubt it would be higher than even 55%

and most TR2's are atleast some 80+ rating.

the older one was 80+ with an 85% rating which is equal to 80+ silver if I'm not mistaken

Right now I have a 650w psu should I move down to 600w and get a 80 plus power supply

No don't move down. If your power supply is reliable then keep it. All 80+ means is that you can save a couple of bucks every year on electricity.
