PSU - Cooler Master vs Corsair

[Feronix]

Hey guys,

As I'm looking to start a new build, I also need a new PSU to go with it. The system will eventually have an i7 3770k, 2x GTX670, 16Gb 2133 RAM, and maybe 2-3 mechanical HDD's and 2 SSD's

At first I was looking at Corsair PSU's as they're supposed to be the very best. I soon figured out that for the price of a Corsair 750 Watt Gold PSU, I could also get a Cooler Master Silent Pro M2 1000 Watt Silver PSU. So I was going for the CM one.

Then, I realised that I would never need 1000 Watt with a system like that, so I went back to look at the Corsair ones and found the AX750 and AX850 to be somewhat close to the price of the CM Silent Pro M2 (the AX850 costing €20,- more).

I'm going for an all black build and i want to use individually sleeved cables. I was looking at the Bitfenix extensions but for these Corsair PSU's there appear to be all ready kits which would eventually cost me about the same, though I'm not sure on the quality.

What do you guys think? Corsair over CM or are both good brands? If Corsair, would 750 Watt be enough or should I go with the AX850 just to be on the safe side?

Thanks in advance!

Would go for the AX750. Great power supply, and you'll probably never get anywhere near stressing it out.

http://www.extreme.outervision.com/PSUEngine is worth a play with. I put roughly your setup in there, and it came back with 480W! h34r:

With SLI 670s?

I'd go for Corsair...

Why not an AX760 or AX760i though?

Whoa! Didn't realise that components had become THAT energy efficient :L
Are you sure you clicked 2 x GTX 670's?

Either way, I have more faith in the experience of the users of this forum than any calc on the internet

Cause the ax760i is out of my budget, and I dont really see any significant difference between the ax750 and 760 that would benefit this build, while the 760 costs as much as an 850. They also dont have the sleeved cables for the ax760(i) where I live

Here is the video TTL did on those Corsair kits:

Looks to be really good. I ordered a white kit for my AX850. For your setup a AX750 would probably do, but the AX850 would give you some headroom.

I would have to agree, go Corsair the warranty you get is legendary and the quality is just amazing!

I also emailed Corsair about getting some extra molex plugs for my AX750 as they didn't include enough for my needs (storage server). Before I was even able to follow up, package showed up at my door.

I don't know about the quality of the CM ones, but I would go for an AX750 or AX860. Personally

I would not buy a 760i or 860i as they are not made by Seasonic, which is the main reason I bought an AX850 in the first place. Also I like the little gold accent on the 850 and the aesthetics of it. I do not like red so I dont like the decals on the new ones and I dont like the design of them either. The corsair link thing is so big I would never use that either.

Some of the AX850s have a bit of noticeable whine to them so I would go with a 750 and I'm sure that will serve your needs very well.

Also I would not personally go anywhere near cable extensions as it just seems half baked to me and creates such a mess inside the case/around the motherboard panel, so if you want individually sleeved then the corsair kit is a good option.

One thing I have noticed though that I do not fully understand is that people who use individually sleeved cables often do not make very tight loops and runs with the cables and often lave very large loops and do not zip them up at all, which ends up looking quite sloppy to me and more messy then a single braided cable in my opinion, but that's just how I feel. I think it's possibly to do a really clean build with individually braided cables but I would run them just as tightly as I always do and zip them up so they are flopping around everything looking busy.

IMO the same sort of things applies to nicely braided cables as does with watercooling tubing, just because you have watercooling and you have tubing in your case doesn't mean you should run loads and loads of extra just so people can see it more, that looks more sloppy to me then running a really clean tight amount of tubing, and I think the same should apply with PSU cables no matter if they are one large sleeve or individualistically sleeved.
