Hi everyone,

I need help with buying either a XFX Pro 750w or a XFX Pro 850w power supply. The 850w version only costs 11 euro (13$) more! Is this useful for futureproofing? And will it make a big increase on the electricity bill? Thank you
System specs right now:
i7 860 @3.6GHz
GTX 260 OC
6 GB DDR3
2 cathodes, several fans with LEDs
1 dvd rom drive
1 card reader

There both great power supplys

On newegg and tigerdirect the 750 has better reviews, People were saying the 850 blows up once in awhile lol, im sure that has been fixed by now

Why do you need so much wattage? A 600w would be more than enough for your system, even if you upgraded your video card to GTX570.

Bigger power supply does not mean bigger electric bill, your still going to be using the same amount of electricity with a 600w or a 1000w.

Gpu's are needing more and more watts at the years go by. So it is safe to get a bigger better psu then want to upgrade a gpu and not have the means to.

Thanks for the reply. But are both of you sure that the electricity bill will not be larger with the 850?

Futureproofing for todays most demanding cards would mean an 850w+ psu.

Your system at present would run off a decent 500w psu.

If you want to save money i.e. less power wastage you need a more efficient psu, silver or gold rated.
You have 2 options really, a gold rated 550w ish psu, this would cover you for any single card upgrade.

Or save some money but less efficient http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Otherwise if you futureproof, this gold rated expensive

Otherwise this is a silver rated better XFX psu than the one you listed and a silly price.

I have just fitted a XFX 850 Core PSU, I only did this because I have just put 2 X 8800GTX cards in and they draw a lot of power and it has the 2 x 6pins plugs i need, even now I have gone a bit OTT
Before that I was using a bog standard 600W, more than enough for my rig then and would be plennty for you now.

Only thing I would say, if you are thinking of upgrading your system to some power hungry equipment then go for the 750 or better the 850 now to save money in the future, but if you'r not, stick with a 600.

it wont affect your bill they both have an identical efficiency curve,and will only provide what you pc needs

I disagree. I think they are getting more power efficient, unless you mean Nvidia cards. Only the extrememly high end cards pull lots of power. In fact you don't need a 850w psu unless your running SLI GTX570's.

Oh and cpu's are getting more efficient as well. All quad cpu's used to be 125-140w. Now they are down to 95w on the quads and run much faster.

Ok, but im going for the 850 anyway, futureproofing and I won't have to worry about a bad PSU.

So the XFX probably isn't as cheap as at Newegg then.

If you stick with Corsair, Seasonic, XFX you shouldn't go too far wrong.

The PRO isn't quite the standard of the Black Ed but still good and a nice looking unit.

The black edition isnt available at the shop :/ . Abut the Core Edition will do just fine
