PSU Recommendation for R9 270X

Hey guys. I can't quite calculate what PSU to get. Here is my build

Intel core i5-3470

Radeon R9 270x

8 GB DDR3

2 or 3 7200 RPM 3.5" HDD

Standard Disk Drive

Standard Mini ITX MB

I have already tried the Newegg PSU calculator and it was saying something outrageous along the lines of around 900w! I'm looking at about a $100 budget give or take, and was planning on getting a Corsair TX-750w for $110. Will that keep this build running or do I need to go higher? Is it over kill and should I go lower?

Thanks.

Definitely overkill! Generally the best idea is the check your GPU's manufacturer's site for recommendations. In this case a 500W from XFX (since they're a really good quality brand) should do just fine.

its tough to tell who's psu calculator tells the truth. i go to this site: http://extreme.outervision.com/psucalculatorlite.jsp and another one to compare: http://pcpartpicker.com/
both have you select your specific parts and it will calculate the power. on the first website it reads that this system only takes about 300w so a 430w or a 500w power supply will be just fine for this system.

I am using a EVGA SuperNOVA NEX 750 G 80 for R9 280x. If you are getting it for R9 270x, it should be enough with the Corsair 750

Hey there, this build will not even pull out 620watts!.900watts is totally wrong. for this build this psu should work flawlessly. -40$ promo from pcpartpicker ;)

Hi,
From personal experience, as you can see my signature, i can tell you that 500-550w is all you need for your system right now. R9 270X will not draw more than 170 watts while gaming.
Here are some suggestions for PSU in the range of $60. If you want less cable mess, go with the Antec
