The one thing I would caution regarding this PSU is that it isn't modular. This results in the usual problems of excess cabling obstructing airflow. If you have the budget I'd recommend paying an extra 10 - 15 for modular. That said this is a corsair 850W for just over 100 which means rock-solid voltage, the 70A 12v power rail can cope with anything up to mid-range sli / crossfire setup and you have a 5 year warranty.

Product packaging and quality is great, slightly larger than standard for ATX but all this meant for me is installing a 90mm fan on the bottom of the case instead of 120mm.

My advice if you're building a PC is to not save money on the PSU. My old rig (going a few years back) had an Nvidia 8800 GTX, 1066Mhz Motherboard FSB and RAM, OC processor and RAID 0 SATA II drive. I picked up an 850W PSU for 50 and 4 months later my motherboard, processor and 8800GTX were dead.

450 of ruined components because I saved 40 on a PSU. You do the math. I'm not saying to buy this PSU specifically but it is a nice budget option. Stick to anything by Corsair, Antec, Seasonic, Enermax and a few select others.

4.0 out of 5 stars Excellent, cool, and quiet. 21 May 2013
Verified Purchase
Excellent PSU, powers two radeon 7970's whilst remaining quiet. Only 4 stars as I had to RMA the first one because inside the housing, one wire was poking into the fan spin area, which subsequently got chopped when the fan started! Do a quick check...!

If you have a need for amps and lots of them then this is the psu for you. We have two desktops both using this psu as it has all the connectors you could need and can supply even the most demanding gpu with the power it craves !

5.0 out of 5 stars Made for Corsair by Seasonic 17 Mar 2014

Fantastic PSU of which I am very impressed by over my last PSU. Not one hiccup nor issue when overclocking ferociously my GPU and CPU. It's silent running and once I get SLI going on, that'll be the only time I can tell how loud and hot it goes when pushed properly but till then, this is just purely fantastic.

3.0 out of 5 stars I think i got a bad system 11 Feb 2014
But i ran this for about a 2 years then i had problems when i upgraded or tried to overclock. Im guessing its just went bad because if i try to overclock my 8320 plus my dual 7850 graphics cards it would shut down. I put in a seasonic 750 gold rated the same company corsair buys alot of their stuff from the 750 gold runs everything perfect but my 850 bronze shuts down so it has to be a bad power source. It ran great before that though .

4.0 out of 5 stars High quality, but not modular 29 Oct 2013
Verified Purchase
Really good performance so far. Works good with the new Haswell power modes and provides all the power needed in demanding games. The only thing is, that the description didn't specify if it was modular or not and it isn't. Now I have lots of cables laying around it the case, which is a bit annoying. Otherwise it's quite good.

I am very pleased with this PSU. I am running some power hungry components in my PC such as two GTX 760's and this power supply runs them very quietly even when under heavy load. Read more
