Hi folks

I was wondering how much watts i m using on idle and load basis. My system

CPU : Intel i5 2300 2.8ghz not oc'ed will be upgrading to i5 3570k or i5 4570 or 4570k after couple of month.
CPU cooler : CM TX3 evo
Mobo : Asrock H61-Hvgs
PSU : Corsair vs 650w
Hdd : 2 hdd 7200rpm (1 tb and 500gb)
Fans : 5
1 DVD writter
GPU : Zotac nvidia gtx 660 Not oc'ed

Please tell me if i have room for upgrade for SSD and Hdd and for any processor listed above.

Please let me know your thoughts and Comments.

Black Box,

I used to add various figures for various components > say 80 to 150W depending on the CPU, 60 to 220W for whichever GPU, 10W per HD and so on, but was never too confident it the results. At a glance I would say your proposed system might be fine with as little as 550W. There seems to be a tendency to err on the side of over-sizing, but it's not a bad idea to consider that power supplies are apparently at their most efficient when the use is about 80% of the maximum load, so it's a but more complicated. Also, the PSU is not drawing the full current all the time anyway and given your intention of upgrading, some oversizing is preferable to undersizing .

My suggestion is to enter all the components in your local Partpicker.com and it will provide a total power use number as well as various compatibility comments. This method usually suggests a higher figure than I calculate > re: the reasons above.

Cheers,

BambiBoom

Yes , you have more than enough power to proceed with the upgrades.

You have 50 amps on the 12v rail , so you have plenty of power to spare.

i5-2300 cpu maxes @ 95 watts for stock speed -(my i5-2400 doesn't hit that unless i am fully stressing it. more like 65ish watts)
cpu cooler ~5 watts
mobo - 7 watts for the chipset and 4 watts for each stick of DDR3 ram.
hdd - ~ 8 watts each
fans - 3-5 watts each
gtx 660 around 120 - 130 watts.

you're at ~288 watts. plenty of room for another hdd (8 watts) or and ssd (2-5 watts)
