| 1387459 | 2014-10-31 23:46:00 | What's the difference between www.pcforce.co.nz and www.pcforce.co.nz all I can see is that one is Gold certified and one is Silver. Gold one is 4 bucks cheaper. In theory shouldn't I go for the Gold Certified one? What's the difference? I'm going to be running an R9 290 and i5 4590. Thanks! |

| 1387460 | 2014-11-01 01:17:00 | Scroll down to the Specifications and you'll see the difference. Not a lot, but one has a higher efficiency rating as well as 1 less SATA connection, input voltage and frequency are also different. The gold is also is on sale where as the silver isn't. | wainuitech (129) | ||
| 1387461 | 2014-11-01 01:20:00 | Is having an extra SATA connector important? (i.e. are you recommending the Gold one?) Thanks for replying so quickly! |

| 1387462 | 2014-11-01 02:06:00 | Oh wait I just read on the r9 290 box that the recommended system requirements are 750W system power supply with a minimum 12V current rating of 24A! Guess I'll have to keep looking then! | Filthygamer (16897) | ||

Guess I'll have to keep looking then! Or would a 550W be fine? I'm reading some forums who say that a good quality 550W would be fine... |

| 1387464 | 2014-11-01 03:28:00 | 550W is enough, I'm running a cooler master GX Bronze 550W at the moment (which isn't a particularly great PSU just ok) with a i7 3770 and a GTX980. I have had a R9 290 running in the same rig for a couple months also and have had up to 5 hard drives in the same box while doing it. The recommended figure is always very high to allow for cheapo PSU's and crazy system configs. The best Idea is to use a calculator like nz.pcpartpicker.com and input your system specs. For added safety margin try adding 10-20% capacitor ageing as per note 4 at the bottom of the page. I just put my specs in with an r9 290, 5 drives, 3 fans, 20% ageing, came up with 492W minimum 542W recommended. Always add everything you think you might one day add as it's a lot cheaper to buy the right PSU now than to upgrade later. 750W would let you run 2 x 290's in crossfire and actually I have run 2 x 280's off a 650W and also a 7970, 7850, and a 6580 (not quite sure on the model but def 6xxx) off a 750w when I was trying litecoin mining. What I'm getting at is as long as you do your research you can ignore the recommended figure. |

RE my first reply, is SATA only the hard drive connectors? i.e. will 5 be enough? Which PSU from above would you recommend for this build nz.pcpartpicker.com ? |

| 1387466 | 2014-11-01 04:29:00 | I'd go for the gold, near enough the same price and more efficient. The bronze, silver gold, etc is just an efficiency rating and the better it is the less power "wasted" in the PSU so less is drawn from the wall - 550W is the rated output, they use more at the wall when maxed out. And lol, how did I link partpicker - meant to link this extreme.outervision.com Yes SATA is all you get these days and if 5 is enough only you can say. I used 5 as an example for PSU loading. Most poeple have 1 OS drive, 1 Optical drive, and maybe 1 data drive for a total of 3. Only us crazy folk add 4 storage drives to a system :) Bear in mind you can now buy single drives of 6TB in size so if you are limited in number of drives you can just get bigger ones. |

Awesome thanks PC part picker gives a close enough estimate as well. I bought the gold certified one that was on sale, all that's left to buy is the hard drive :D |
