Hello,

Well i have basically want my pc for gaming purposes only. My current specs are:

Intel core 2 duo 2.93 ghz
4gb ddr2 ram
160gb hard disk
PCIE 16 2.0 slot

I had a 9800GT but it aint working anymore

Now im planning to get a 9800GTX+ card to install in my system(I know its an older generation card but im getting a very good deal on it)
So could you guys help me to choose a decent Power supply from the following depending on my needs?

I only have the above components (No optical drive/multiple HDD/flopy drives)

The Ones i have shortlisted are:

1.Corsair VS550
http://www.flipkart.com/corsair-vs550-550-watt-psu/p/it...

1 rail +12v -not sure but should be more than 25A


2. GIGABYTE E620
http://www.ebay.in/itm/Gigabyte-Superb-E620-GENUINE-600...

2 +12 V rails- 18A each


3. Corsair vs450
http://www.flipkart.com/corsair-vs450-450-watt-psu/p/it...

1 +12V rail-22 A


4. corsair cmp 500cx
http://www.flipkart.com/corsair-cmpsu-500cxv2uk-500-wat...

1 +12V rail-34 A


5. antec vp450
http://www.flipkart.com/antec-vp450-450-watts-psu/p/itm...

2 12V rails-18a each

Now i know the 4th one would be the best option. But what about the other power supplies? Will either one of them b enough to power my rig considering the overall wattage as well as the ampere rating on +12v line? I would like to go with the cheapest one.

Suggestions and views would be a lot appreciated

Thanks

Going with "cheapest" one for PSU is generally a very bad idea. Get the "highest quality" one that you can fit into your budget. That being said Corsair is a good brand, and having 1 rail with high Amps is a better solution then getting multi 12v rails with lower amps per rail. Go with the Corsair 500cx.

For a system using a [#88900ff]single GeForce 9800 GTX+[/#8800ff] graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers may overstate the power supply wattage, usually by at least 50 Watts, in an attempt to take into account some of those power supplies that have the weaker +12 Volt rail(s).

The Antec VP Series 450 Watts (VP450), with its maximum combined +12 Volt continuous current rating of 30 Amps and with one 6-pin PCI Express supplementary power connector, is electrically sufficient to power your system configuration with a single GeForce 9800 GTX+ graphics card. It is deficient by one 6-pin PCI Express supplementary power connector so you'll have to resort to using a dual 4-pin Molex peripheral to 6-pin PCI-E adapter cable.

The Corsair VS Series VS450 (SKU# 75-001835 / CP-9020049-WW), with its maximum combined +12 Volt continuous current rating of 34 Amps and with one (6+2)-pin PCI Express supplementary power connector, is electrically sufficient to power your system configuration with a single GeForce 9800 GTX+ graphics card. It is deficient by one 6-pin PCI Express supplementary power connector so you'll have to resort to using a dual 4-pin Molex peripheral to 6-pin PCI-E adapter cable.

The Corsair VS Series VS550 (SKU# CP-9020050-WW), with its maximum combined +12 Volt continuous current rating of 42 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce 9800 GTX+ graphics card.

The Corsair Builder Series CX500 V2 (SKU# CMPSU-500CXV2UK), with its maximum combined +12 Volt continuous current rating of 34 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce 9800 GTX+ graphics card.

The GIGABYTE Superb E620 (GE-E620A-C3), with its maximum combined +12 Volt continuous current rating of 36 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce 9800 GTX+ graphics card.
