How many watts for PSU?

[badgerbadger]

I am building a new computer and was wondering how many watts my computer would need here is my setup

Amazon.com: Intel Core i5-760 2.8GHz 8 MB LGA1156 Processor BX80605I5760: Electronics (i5 760 2.8 ghz)

Newegg.com - GIGABYTE GV-N460OC-1GI GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
(gtx 460)

Newegg.com - GIGABYTE GA-P55-USB3 LGA 1156 Intel P55 USB 3.0 ATX Intel Motherboard
(ga motherboard)

Newegg.com - G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL8D-4GBRM
(g.skill ripjaw 4g ddr3 1333)

Amazon.com: Arctic Cooling Freezer 7 Pro Rev.2 - Processor cooler - ( Socket 775, Socket 939, Socket 1156, Socket AM2, Socket AM2+, Socket 1366, Socket AM3 ) - 92 mm: Electronics
(arctic cpu cooling fan/heatsink)

Amazon.com: Seagate Barracuda 250 GB 7200 RPM SATA 3Gb/s 8MB Cache 3.5 Inch Internal Hard Drive ST3250318AS-Bare Drive: Electronics
(seagate 250 sata 3.0gb/s)

and a old DVD RW

what would be a good PSU for this set-up?

I would go with a high quality 650W like a Seasonic, Corsair or Antec! I would also look at an Asus motherboard instead of that Gigabyte, unless you already bought it, also Seagate is not recommended we recommend Western Digital on this forum.

We also discourage G.skill memory, especially the Ripjaws. It's been having quality and compatibility issues with P55 boards. Go with Corsair, Crucial, Kingston, or A-Data.

okay here is some revised items

(power supply)
Newegg.com - Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply

(Ram)
Newegg.com - CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX4GX3M2A1600C8

and for a different motherboard, I'm not really sure on the difference between

Newegg.com - ASUS P7P55 LX LGA 1156 Intel P55 ATX Intel Motherboard
and this
Newegg.com - ASUS P7P55D LGA 1156 Intel P55 ATX Intel Motherboard

thanks for the help!

The LX is the entry level board. The other one adds eSATA and Firewire. Neither one has USB 3.0 or SATA 6.0. This one would actually be my choice:

Newegg.com - ASUS P7P55D-E LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

I would go for this PSU instead of the one you listed. That Antec is a good unit but this Corsair has a single 12v rail which most are recommending in this forum.

CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
