Is PSU adequate for system?

Anton Hunter · Dec 19, 2013

I need to know if the Corsair TX850 V2 PSU will adequately power my system which consists of:

-AMD FX-6300
-Asus M5A99X EVO R2.0 ATX AM3+
-G.Skill Ripjaws Z Series 16GB (2 x 8GB) DDR3-2133
-Asus R9280X-DC2T-3GD5
-Seagate 1TB 7200RPM
-Samsung SH-224BB/RSBS
-Scythe SCMN-2000
-Creative Labs Recon3D PCIe
-Windows 7 Professional SP1 (OEM) (64-bit)

Also, is it overkill even though I'll be OC'ing mid to high range? Or, would the TX750 be enough?

Yes it is overkill.
TX 750 is a good supply and it has plenty enough power for your system.

I was concerned because when ever I looked into R9280X or R9290 GPU's there was always a notation in the system requirements list for a minimum 750W PSU. So, I decided to look for one with as much pwr available on the rails as I could find. PCPartsPicker listed my build at 476W which I thought was a bit low, but, hey, that's why I'm looking for intel here on this site! Is there any chance I could get you to break it down for me a bit and explain why the 750 should do the trick? I don't want to be a pest; but, I am hungry for knowledge. ^_^

all depend on the price.... more you have powerful psu better is , above all for the futur if you want to upgrade
actually with the rig you have tx 750 is enough

Anton Hunter :

AMD FX-6300 = 95W (at stock)
R9 280X = 250W
Other components = 50W
Total = 395W
Let's allow 10% extra for your overclock = 435W

You want the power supply to run at most at 70% load.
This is because they get much less efficient above 80% and it may reduce the life of the power supply.

435W / 0.7 = 621W
Hence a 650W supply is enough.

Thanks...I appreciate the input, guys. I'm just trying to be careful. I've discovered that TX750-V2 is manufactured by Seasonic; so I'm assured of its good quality.

Anton Hunter :

It is a lower end model compared to models sold under the Seasonic brand.
The Corsair TX series is good quality with an 80 plus rating.
Seasonic G 750 for instance is 80 plus gold rated.

This is what I was looking for. Your explanation pretty much covers it...and you made it look easy. Thanks. I already punched the "solution" button before I got this answer from you...sorry! So, the TX750 it is!

Get the TX 750 it's a high quality power supply and will also leave you for room for future upgrades.

Anton Hunter · Dec 19, 2013

Agreed! ^_^
