Please Help Me Choose a New 750/850W PSU :)

[MandrakeAU]

Greetings gentlemen (and ladies!). My current PSU, a venerable 850W Zalman unit, seems to be getting a bit long in the tooth. It's been making some odd hissing sounds and it's also nearly 7 years old! With this in mind I've been researching a replacement unit. I'd like something in a similar wattage range.

My system specs are as follows:

-Core i7 4670K, overclocked at 4.4GHz with a Corsair H100i
-ASUS ROG Z87 Hero motherboard
-16GB (2x 8GB) G-Skill DDR3 1600
-3x 4TB HDD, 1x SSD, 2x BD Optical Drive
-Creative Sound Blaster Z
-Gigabyte GTX 780 overclocked at 1.1GHz

All of the above is crammed into a Corsair Obsidian 700D, so the PSU can be a longer unit without issue. I'd like to keep my options open, that's why I'm looking at a 750W to 850W unit. This should be enough to accommodate a second 780 or indeed a different SLI configuration in the future if I decide to go down that route. I expect the new unit to last at least five years, so I'm not looking for a cheap PSU. I'd also like a modular power supply if possible, although that isn't absolutely critical.

With that in mind I did some research and found the following:

Corsair RM 750/850W:

EVGA SuperNOVA G2 750/850W:

Did anyone have any specific recommendations, or indeed perhaps a different manufacturer in mind?

I was looking at the 850W EVGA. It's gotten fantastic reviews and has very solid specs and would handle SLI 780s without breaking a sweat. At the same time Corsair has some higher end units like the AX760 and AX860. Would there be merit in spending another ~$100 AUD over the EVGA unit for the same wattage range? I'm happy to pay for a quality unit but don't want to overspend unnecessarily.

Any advice greatly received. Thanks.

Antec makes a good PSU so does FSP. I have an Antec gamer 520 and it's been good to me.

Antec doesn't actually make PSU's, they use other OEM's. Your HCG-520 is basically a rebranding of a Seasonic S12II 520W, it's good but slightly outdated.

@ OP

I second the EVGA 850W G2 suggestion. One of the best performing 850w units on the market with 10 year warranty. Manufactured by Super Flower. And the price is right as well, it's less expensive than the competition from Seasonic and Corsair.

get the G2, you will be happy.

Thanks. Editor's Choice award from PCPer was good. 9.9/10 from JonnyGuru is an even more impressive endorsement! Ordered the 850W EVGA, should arrive today.
