Power Supply Necessity?

Well I am looking to piece together a new new PC and trying to decide if I need to upgrade my PSU. I currently have a CORSAIR CMPSU-620HX.

I was curious if I needed to upgrade to another PSU if I put this hardware together...


Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

EVGA 132-BL-E758-TR LGA 1366 Intel X58 ATX Intel Motherboard - Retail

EVGA 01G-P3-1285-AR GeForce GTX 285 SC Edition 1GB 512-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Retail

Intel Core i7 920 Nehalem 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920

2 - CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory Model TR3X6G1600C8D - Retail

Pioneer 20X DVD±R DVD Burner with LightScribe Black IDE Model DVR-1910LS - Retail


Well Besides those there may be another internal harddrive...



Well anyone think I need to upgrade the the Corsair 1000HX would be necessary?

According to nVidia's site you will need at least 550W to run that card so you should be ok with that power supply.

That PSU should run any single card made.
