lets keep this short and sharp would this psu be fine for and fx-8350 @4.5ghz and 2 r9 390's

While it would probably work, 1000W is recommended for Crossfire 390's.

It will be sufficient. Close, but sufficient. It's solid quality http://www.hardwaresecrets.com/fsp-aurum-pro-850-w-power-supply-review/

thanks for the answer i might go for the 1000 watt version then it's $60 more

 

[turkey3_scratch]

What prices are you looking at for these There are probably better units for the money IMO. If you are buying a new PSU, then yes a quality 1000W unit that meets its labelled wattage as RockyPlays said.

hi again turkey thanks for the answer i actually own an fx-6300 at 4.5ghz but 850watts would give me head room for a fx-8350 if i decided

If you do plan to pair 2 390's with an 8350, I would definitely recommend at least 1000w since they are all power hungry components, especially when overclocked.

this brand of psu has 3 levels of psu to pick from a 850, 1000 and a 1200 wattage and the 850 watt is $213 NZD and the 1000 watt is $260 NZD

 

[RockyPlays]

And this is the only brand available to you?

yes i was just on the same website if you remember me i was going for that 700 watt antec one u suggested

Okay, New Zealand, so more limited options. Here is a review of the 1000W model, which performs very well: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=292

I guess it is up to you. I would recommend the 1000W unit. Better efficiency is one reason.

no i just noticed it in a pc shop close to we're i live and i took one look at it and thought lets check this out

ok ill get the 1000 watt version would it be bad for the psu if i have one r9 390 with it for a while before i get a 2nd

 

[turkey3_scratch]

No that would not be bad at all, if anything it'll just be less load on the PSU which isn't a bad thing.

 

[RockyPlays]

Ok sounds good. And no, the extra wattage shouldn't cause any problems.

i just did this does this mean the 850 would be fine

UPDATE: i ment this one http://outervision.com/b/0iN9BP

If you're talking about a wattage calculator (I don't like to visit sites I'm unfamiliar with) ignore them. They are not very accurate, and there is more than wattage. The primary rails are the 3.3V, 5V, and 12V rails. Increased load on the 3.3V and 5V means less potential current on the 12V. Also, as temperature of the PSU rises, potential decreases, so there are a lot of factors that play into effect here. You also start losing efficiency which also means more heat in ratio to the amount of DC and more heat = decreased lifespan of capacitors.

ok so i'll stick with the 1000watt yes it was a psu calculator and i did worse case senrio on the calculator and power peaked at 771watts

 

[RockyPlays]

Yeah, even if just for the peace of mind that it gives you.
