How many watts will my system need?

[CptThunderPants]

I am building a gaming computer for myself, and i dont know how many watts of power it will need. Here are the Specs:
Processor: AMD FX-6300 Vishera 6-Core 3.5GHz (4.1GHz Turbo) Socket AM3+ 95W Desktop Processor

Motherboard:ASUS M5A97 LE R2.0 AM3+ AMD 970 + SB950 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS

Graphics Card:GIGABYTE GV-R927XOC-2GD Radeon R9 270X 2GB 256-Bit GDDR5 PCI Express 3.0

RAM: G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600

Hard Drive:Seagate Barracuda ST500DM002 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive

Optical Drive:SAMSUNG DVD Burner SATA Model SH-224DB/BEBE - OEM

Operating System: Windows 7 Home premium 64 bit

Thank you: And is this overall a good Build for about an $850 budget?

Here is Guru3D's power supply recommendation:

AMD R7 260X - On your average system the card requires you to have a 450 Watt power supply unit.
AMD R7 260X Crossfire - On your average system the cards require you to have a 650 Watt power supply unit as minimum.

AMD R9 270X - On your average system the card requires you to have a 500 Watt power supply unit.
AMD R9 270X Crossfire - On your average system the cards require you to have a 700 Watt power supply unit as minimum.

AMD R9 280X - On your average system the card requires you to have a 550 Watt power supply unit.
AMD R9 280X Crossfire - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

SR-71 Blackbird said a 550W power supply but I'd disagree with that. It's a bit tight to the 528W your system may need. Also he says XFX which I disagree with. I'd recommend http://

It say's it's out of stock but go for something around 600-700W which allows room for upgrades.

550w IS MORE THAN ENOUGH.

Blackbird is on target .... XFX like most companies makes some excellent PSUs and some other PSU's that I would not put in a enthusiast's system. Corsair also makes some excellent PSUs (HX / RM series) but the CX series is not one of them .... just about every CX review includes the "for the money" qualifier. And yes, while it's a capable PSU for light office duty or grandmas box to share pics of the grandkids, it's just not up the the level of quality (cheap capacitors) of an enthusiast system. The 430 was the best of the bunch and it only got a 7 build quality rating from jonnyguru.

Only point Id wanna make regarding the XFX Core edition series is that the 650 (9.5 performance rating) was a lot better than the 550 (8.5 rating)
