Motherboard - GIGABYTE MA785GMT-UD2H
Processor - AMD Phenom II X4 965 Black edition (3.4ghz)
RAM - 2x 4gb(8gb) DDR3 PNY 1333mhz
Power Supply - 520watt
Graphics Card - AMD Radeon HD R6670 XFX Core Edition 2gb DDR3
Screen - LG 23 inch LED monitor
HardDrives - 1TB, 500GB, 250GB
PSU - 520watt
i ordered a new graphics card (AMD R9 270X) a few days ago and got it in the mail and i was thinking if my PSU could even handle all my stuff plus the new GPU. The card says it requires at least a 500 watts PSU. but would my PSU beable to handle it? I am planning on upgrading my PSU soon to maybe about a 650 or a 750 watt psu soon to a more trusted brand lol (tho i havent had any known problems with this psu just herd this brand wasnt a very trusted one).

Do you think my PSU can handle this card for a while till i can afford a new PSU?
Thank you

I just used the cooler master power supply calculator and 1 time it gave me 437watts and another was 480watts also i can unplug 1 of my hard drives and my disk drive and i have a fan on the side, if that would help much at all..

Should be fine if it's a decent PSU, have plenty more than would be required
