Need help to choose a PSU for my config

[metallicmaggot]

Hi,

I am building a new machine primarily for Gaming. The config is as follows:
Cabinet : Corsair Carbide Series 400R Mid Tower Case
Processor : i5 2500K
Motherboard : Gigabyte Z68X-UD3R-B3
RAM : Corsair Vengeance DDR3 (CMZ4GX3M1A1600C9) (2 X 4GB)
Graphic Card : Asus GF GTX460 1GB (ENGTX460 DIRECTCU/2DI/1GD5)
SSD : 2 Corsair Force Series F40A 40GB
Hard Drive : Western Digital Caviar Green 2TB
Fan Controller : NZXT sentry 2 touch screen fan controller (Not really sure but might add)

I can't figure out how much wattage should the PSU that I buy have. Using http://extreme.outervision.com/PSUEngine (with 95% CPU Utilization and 15% Capacitor Aging) I get about 449W as recommended. I will never go for SLI, I will never overclock. This is the config which will remain such for atleast the next 2 years.

How much wattage should I go for? And which is the best available PSU with that wattage?

Thanks!

a k version cpu with z68 and still no overclocking

you need minimum 450-500w with minimum of 30a on 12v

For a system using a single GeForce GTX 460 graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a 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 a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

Even a Seasonic S12II-430 Bronze, with its +12 Volt continuous current rating of 30 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient since it exceeds the minimum requirements.

How much have you allocated for your power supply budget?

Hi KO888,

Thanks for your input. I am keeping about $100 for the PSU. I was considering the Seasonic S12II-620 620 watts PSU, using the PSU calculator at extreme.outervision. But after your post I believe I should consider the 520 version of the supply just in case I throw in a couple of accessories in future.

In India the problem is that we can't really run our PCs without the UPS, and that is an added expense depending on which power supply to pick up. Hence I wanted to keep my wattage to a minimum so the UPS cost is not really high. I just hope I am going the right way, really bad with watts and volts

Although you can't really go wrong with the Seasonic either.

Be safe and get a Corsair 650w

Smart on your part to choose a Seasonic.

Thanks everyone for your effort and inputs. Really appreciate it.

I have got myself the Seasonic 620W S12II and I hope it should work out for me even including a few future upgrades.

Thanks everyone again.
