Hello all.

My GTX 770 came in the mail today and my PC is officially fully built running Ubuntu 13.10.
I read the specs on the GTX 770 and it says that I need a minimum of a 600W power supply, which I have. But now I'm scared that I have no wiggle room to say, add another hard drive, for example. I used this tool to calculate my "Recommended PSU Wattage," which suggests 444 Watts, but I am, however, still a little skeptical that my 600 watt power supply is sufficient. Especially if I plan on ever upgrading. Has anyone ever used this tool and can vouch for its reliability. Here are the relevant specs:

Intel Core i5-4670K 3.4 GHz Quad-Core (BX80646I54670K) Processor

Gigabyte GeForce GTX 770 OC 1189MHZ 2GB Video Card - 84048

CORSAIR CX series CX600 600W (What I'm asking about!!)


Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW

Lite-On Super AllWrite 24X SATA DVD+/-RW Dual Layer Drive - Bulk - IHAS124-04 (Black)

Kingston Technology HyperX Blu 8GB 1333MHz DDR3 Non-ECC CL9 DIMM (Kit of 2) KHX1333C9D3B1K2/8G

Penguin Wireless N PCIe Card for GNU / Linux v4 (TPE-N300PCIE4)

Penguin USB Bluetooth Micro Adapter for GNU / Linux v2

N Logitech K360 Wireless Keyboard

Transcend TS-RDP5K USB 2.0 Card Reader

Logitech Wireless Mouse

Thanks in advance.

ps. the only thing I find close to monitoring my power consumption from Ubuntu is PowerTOP. It doesn't give information about watts. Anyone know of any software out there that is capable of accurately monitoring power consumption on a desktop?

with power supply guild of 600w for the gpu. they do that because that want the amp rating on the 12v line to be higher then the card needs. take the wattage of the cpu and the max wattage listed for the gpu and devised them by 12 for the amps. then look at your power supply 12v line for it amps and wattage. hard drives and ssd and cd rom are low wattage and low amp devices.
