Corsair HX1000i alternative?

[Fireman Dave]

Hi all

Looking at purchasing a quality 1000w (ish) PSU (planning on purchasing second R9 290 and OCing 4790K in near future).

I have my eye on the Corsair HX1000i. All reviews seem great, but like to see what others think?
Antec High Current Pro Platinum 1000W? Seasonic XP-1050 Platinum 1050W? EVGA SuperNOVA 1000W? Something else?

Thanks =)

Please note that I am from Australia, the land of inflated tech prices and minimal choice!

I personally have good experiences with Seasonic PSUs, and one of my dad's collegues who builds computers for his department also stands by Seasonic, he has never seen one fail over the years.

According to the ones you have selected, Seasonic and Antec are tier 1 (the best) according to the inhouse list:

The other two are Tier 2, but they are still capable units.

My initial reaction is that you should consider this form: http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html

You are going to want a Tier 1 or 2 psu. Depending on your budget of course.

I personally recommend Seasonic or EVGA. Seasonic is the company that manufactors the corsair ax series psu's, and have features such as fanless mode which I am personally fond of (although some dislkie it.) EVGA on the other hand has really stepped up their quality and overall value in recent years for psu's and are therefore another brand Id recommend.

I also ran a couple psu calculations and based on the info you gave plus a couple worst case scenario selections (h100i cooling, 5 fans,4.8 OC, 4 sticks of ram...) I got a recommended wattage of about 700. Now if you account for capacitor aging of 25% you are at about 850 watts, so if you want you can save some money by reducing your psu wattage, especially considering all upgrades to your system, especially in the gpu will be more efficient than the 290s you have selected now.

I'm reading more about the SS XP3-1050, and it is indeed sounding rather nice.
I have the money for a 1KW + unit, so I'd prefer to go that way. OuterVision's PSU calculator recommends 946W, but then I have all manner of crap in that box =P

Looks good. The calculators are great tools and if you have the money definitely get more watts. Seasonic is a great psu, I run the 800 watt version in my build atm and its amazing. You will not have any issues. Their tech support is pretty good as well.

Also I know this is unrelated to your question but your cpu voltages seems a little high?
