rm is better quality and silent optimized, no fan rpm until 40% or so.

Ah i see, but by "Quality" do you mean that VS650 may actually be bad for my pc? because i do not mind spending a bit more if it means keeping my pc safe! :)

Quality power supplies do tend to have better protection circuitry though I don't know enough to compare those models exactly and you should always use a Surge Protector as well.

Neither power supply is likely to allow damage to your computer.

Quality also means the longevity of components so the power supply is statistically likely to last longer.

Quality can also mean a better design eliminating causes of noise such as the fan, coil whine etc.

I checked and the "v" series is not available but GX series is available but costs a bit more than even the RM650!

Also in the official site it shows that the RM650 is a "Gold Class" psu whereas the VS650 has a "No Class Applicable" tag so the RM650 is obviously the superior choice. But is it really worth it going that extra money mile ? :)

what budget do you have?the gold rated efficiancy the RM has doesnt reflect on its quality. for the money these units cost, you can have better options.

The RM650 definetly costs more yes, and i was looking for Seasonic/XfX products but very little of those products are available here in India.

Corsair is available readily and in abundance! But is there any other brand i should be looking into ? Except Corsair/XfX/Seasonic ?

Thank you for replying!

well isnt flipkart an option?im not that familiar with the indian market.these psu are all good choises. consider the Seasonic S12II 620 Watts as the best option for the money, more than enough for your setup.

Antec VP650P 650 Watts PSU
Seasonic ECO 600 600 Watts PSU
Seasonic S12II 620 Watts PSU
Corsair CMPSU-GS600W

They are not the same. Not even close.

The Corsair VS650 is 200-240VAC input only and doesn't qualify for any level of 80 PLUS certification.

The Corsair RM650 has Universal AC input from 100~240 Volts. It has 80 PLUS GOLD efficiency certification.

The Corsair RM650 is definitely Haswell compatible because of its modern DC-to-DC circuit design whereas the VS650 is based on an older group regulated circuit design and is not Haswell compatible.

The RM650 has modular output cables where the VS650 has full wired output cables.

The RM650 is quieter than the VS650.

The RM650 has better electrical performance than the VS650.

YES!
Flipkart is an option but i was a little bit confused on the Seasonic section as there are a lot of models under the 650w tier :D  also will 620w be enuogh for gaming ? { I will never do SLI}

Thank you for the awesome reply!!!

The Seasonic S12II Bronze Series is not Haswell ready. If you use this PSU with your system you will need to disable C6/C7 power state support in the motherboard's BIOS.

you can check the haswell compatible units here http://www.realhardtechx.com/index_archivos/Page541.htm . having a no harswell compatible psu isnt a problem actually worst thing is that after sleep mode you might not be able to wake it up, or a protection may trigger and shut of the unit. if you still need the haswell compatability with less money than rm you can have this Seasonic S12G-650 650 Watts PSU and review

The system not waking up after entering C6/C7 sleep state is a problem. If it wasn't a problem then there would be no need for Haswell compatible PSUs.

The problem can be avoided altogether by getting the right PSU.

i agree haswell compatability should and must be considered when needed. i wouldnt mind paying less though for a non haswell psu but still great as a unit, since it can be bypassed. that is just my personal preference and i really, i should have mentioned it.!
