GFX Card: GIGABYTE Radeon R7 250 (1100MHz), 1GB GDDR5 (4600MHz), PCI-E 3.0, DVI, HDMI, VGA
RAM: G.Skill 8GB (2x4GB), PC3-12800 (1600MHz) DDR3, Ripjaws X, 8-8-8-24-2N, 1.5V, Dual Channel Kit
SSD: SanDisk 128GB SSD, Ultra Plus, SATAIII, Read up to 530MB/s, Write up to 290MB/s

Hello r3b3lw0lf. Welcome to the forum.

Go here:
http://extreme.outervision.com/psucalculatorlite.jsp (site is down at the moment - should be back soon)
and fill in your system specs to get your answer.
At the end you will see a box for Capacitor Aging. Use 10% if you plan on replacing the power supply or PC in 2 or 3 years, use 50% if you want maximum lifespan.

There are others, just not as comprehensive. This one's OK:
MSI USA - Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more

Thanx for the response eblen.

yeah I have seen a few of those from this site.... that first one... well didn't know nothing bout the aging and such capacitor, the recommended wattage was like 530w or something....
then the was that PSU REQUIREMENTS - RealHardTechX and it tells me ... "The “Recommended PSU Wattage” value is for the whole system, not only for the graphics card/s."
R7 250 <=-- gfx card 380watts <=-- recommended 0 <=-- 6pin 0 <=-- 8pin
and well really got confused then LOL... hence why I came here, to see if someone could give a more accurate guesstimation

Hmmm that second one, told me 103 watts...

Hence my confusion LOL

Is 500 powerful enough you reckon?

Basically what it means is the system will need a 530W psu to cover a 10% degradation.

Your GPU Card will require ~100W of power.


If that is the total / final build of the computer then yes 500W will cover it happily.


However! If you plan on adding a new GPu / HDD at some point in the future, you will need to get a slightly larger size to cover it.

Googling says that the R7 250 consumes a maximum of 65 watts under load.

Doesn't look like you could use more than 250 or 300 for the whole system.

So, yeah, 500 would be plenty, or even less assuming you got a quality brand and model.

Handy site for checking a GPU's draw power / bandwidth : http://www.hwcompare.com/


Not trying to correct you, just sharing an awesome resource i use when building machines.

Yet, the specs say....
Power requirement 400W
GIGABYTE Radeon R7 250, 1GB [GV-R725OC-1GI] - $99.00 - Scorptec Computers

are there two different meanings for W and watts?

I am putting these together (well they are building for me), buts its like my first selection of parts LOL... just need the psu now.
I didn't wanna buy a new one, when I got those parts, cos it would be extra 55 for labour PLUS the cost of PSU (and I figure I wanted ssd AND gfx card, better than the price of getting psu through them)... and we all know that the cases WITH psu already are crapola LOL, so picked the case I wanted and I gotta provide PSU (which won't come under the build warranty), so am on the hunt for one that will do me. I have a Vantec ion2 500W that im using atm in this one, and if I could, I would add it for the new one... but not sure if its will cause problems

I do not plan on doing any crossfire/ sli stuff, just using that one gfx card gddr5 (apparently better then a 2g ddr3 240)

As a minimum supply, yes.
What I do is look at pricing at the moment. If I see that I can get a larger power supply for the same price or a bit more than the minimum required supply, that's what I do.

It also depends on the quality of the supply. Higher end supplies made by Seasonic and others sold as Corsair or Antec etc. will put out the required minimum reliably longer than cheaper supplies.

Wait until the Extreme Calculator comes back on line. It is a much better calculator.
The MSI calculator is giving you the actual power draw of the system components entered, running at 'normal' capacities. However you would never try and run a system on a power supply running at 100% capacity every minute. So the rule of thumb is to double the result (so the supply is running at 50% of capacity - less heat, less wear).
And then you want to add so "overhead" to account for the addition of more components later. So plug in an extra hard drive or 2, another optical drive, and a sound card (even if you don't plan on getting one), and you will at least be prepared for any future upgrade.

No thats 400W when running with their version of a barebone PC setup, so all the necessities included.

The figures we posted above are how much the unit will use on it's own.


For a PSU, check out the Corsair builder series > Corsair Builder Series CX 500 Watt ATX/EPS 80 PLUS Bronze Power Supply Unit: Amazon.co.uk: Computers & Accessories

Very good company, and made for pc builders in mind.



Yes GDDR5 is 4x quicker the GDDR3 i beilieve is how the base rate works with the bandwidth. It used to be,
DDR x2 = DDR2
DDR2 x2 = DDR3

and so forth.

No, in this context. W and watts are the same.

400W is presumably the recommended PSU wattage and takes into account the typical ENTIRE SYSTEM, not just the graphic card itself. I don't see any contradiction.
