loud corsair HX1050

Just got a HX1050 PSU when playing a game the fan ramp up. When it does its loud. should I be looking for another PSU.

Why the fuck did you get a 1050w PSU? Are you running tri-SLI?

That's like putting a microwave in your computer case.

1000w psus dont usually speed the fan up until they're about at 70% capacity.

you're probably hearing your video card.

Indeed, he should know about such as that by now though, chambers, have you even opened the case and actually checked this? Why on earth did you get such a high wattage unit? I wish you'd follow the advice people keep giving you.

Because he, like a good majority of the "enthusiasts" crowd, is the exact type of person/demographic that marketing departments cater to. What this has resulted in is the following mentalities:

1) "Bigger numbers are better"
2) "I always want the best and {what I think to be} top of the line"
3) "I can't find any reviews of the product for any other model than the biggest one"
4) "I'd better not chance it"

Item (1) became a serious issue starting with the megahertz wars, which was happening at about the same time (roughly 1999 or so) when the Web and online activities were really beginning to take off -- and "enthusiasts" have never been able to distance themselves from that history. It is embedded even in the brains of the young. It's akin to the blast processing that Sega marketing created in the 80s. I'm sure I could work a car analogy in here somewhere too (such as "car enthusiast" wackos who think performance is all about torque).

Item (2) is, well... it applies to everything pretty much, not just computing. Too long to go into here.

Item (3) is a direct result of PR and marketing control; the way most popular/mainstream review sites work is that the reviewers ask Company X for Product Y to review, or sometimes Company X offers. In return, there's an exchange of revenue, or if not, bare minimum, an unspoken agreement established between the two -- "give our product good reviews and you'll keep getting free products from us to review". The driving force here is one thing: money. Review sites are often littered with ads (as someone who did hosting for 18 years the costs can add up real quick) to bring in money to pay for the site and/or act as a sole form of income for the site founder(s), while simultaneously Company X is making more money because Product Y is now selling like hot cakes. I cannot tell you how many times I've tried to find reviews of specific models of products only to find that their costs-3x-more-for-no-good-reason counterpart is the only one reviewed everywhere. This is why any reviews I've done, for example, are done with money coming out of my own pocket -- no outside influences. Of course, given my scathing opinion of most products these days, I imagine I'd be a thorn in the sides of most companies. Heh.

Item (4) is understandable to some degree; you know the saying "ignorance is bliss". We have to admit possibly jchambers28 See Profile bought a high-wattage PSU because maybe down the line he wanted something like a dual-card setup with cards that have dual GPUs on them (i.e. power hungry). That may or may not be the case though. But my point is that forward thinking is sometimes justified. It depends on the person; yeah, I know how him and Oleg See Profile are, but on this item I'm trying to give them the benefit of the doubt.

Bottom line -- marketing caters to the "enthusiast" crowd for one reason: they know these folks have money burning holes in their wallets. My minimalist attitude conflicts with this greatly, not to mention my moral fibre, but at the same time if I turn off my opinions there is the fact of the matter that their money is their money, even if not wisely spent.

Anyway, back to the tech part of this. It's possible that his PSU fan kicks on (if it is the PSU fan) not so much as a result of the PSU itself being high wattage, but as a result of how much power he's drawing from it. It would really help to get a full inventory of what all the system consists of (motherboard, video cards, drives, external devices, everything). Putting a Kill-A-Watt metre in front of the PSU would also be wise -- when the fan kicks on, look at the wattage draw and see if you can correlate the two. If the PSU is drawing, say, 700W, then it's time to figure out what's drawing that much power and why.

Re: loud corsair HX1050

This forum has repeatedly tried to give this user advice. He asks for, receives, then ignores it. Or comes from the outfield with an oddball purchasing decision, like this one.

Great post, Koitsu. You encapsulated the mindset perfectly. #4 is the most common explanation. Power requirements can be a bit fuzzy, as only GPUs and CPUs have readily available consumption limits, so many people "play it safe" by buying a much larger PSU than they need. At best, it's spending a little extra for peace of mind, but becomes wasteful at the extreme end.

A possible fifth explanation would be that the consumer misunderstands how a power supply functions, and believes that a 1000w PSU will make a computer "run better" than a 600w or 800w PSU, and deals with it like a free ram upgrade ("hey, I might not use 8 GB, but it's only $40 to go to 16GB! future-proofing!").

And yet the trend for video card TDPs is to fall as manufacturers put out increasingly efficient cards (look at the GTX 480 vs. GTX 680).

here is the wattage limits 686 watts. I only load a PSU to 80% of its capacity. they start really getting loud.

And how much power is your system actually using when the PSU fan kicks on (again, assuming it is the PSU fan)? Kill-A-Watt metre, dude.

Remember that *max* efficiency of the HX1050 is 88% (86% under 110VAC, and 89% under 230VAC), which is under ideal conditions/load.

At half load (535w), your PSU just misses the SILVER mark and performs at 86% efficiency, which is between SILVER and BRONZE.

»www.overclockersclub.com/reviews···50/5.htm


The Corsair HX1050 produced a fairly typical set of results in this section that fell a little short of the 80 Plus Silver requirements (85%, 88% and 85% efficiency at 20%, 50% and 100% DC loading) following the OCC power supply testing methodology. The OCC power supply testing methodology doesn't exactly replicate the rail loadings and a shortfall of one or two percent isn't unusual so it would be unfair to mark the power supply (or any other that produced similar results) down in this section. Power factor levels are rarely if ever a problem in high end power supplies, especially with a 110VAC supply, and the HX1050 easily kept the level above the required 0.9 mark at 50% DC loading.

As the article says, we're essentially arguing semantics. You bought a much larger PSU than you needed, but it's not going to cost you much in terms of inefficiencies, and it's not going to harm anything.

That's about 430w in power coming out of your PSU to the rig, then.

I would have recommended a PLAT-rated 500-550w PSU, but whatever floats your boat, man.

With what? A 660Ti or 560Ti? I can't remember what you ended up going with.

»[Parts Check] new build

Weren't you the guy who Crossfired 5850s? Or was that Oleg?

A second GTX 660Ti adds 150w load (max), a GTX 560Ti adds 170w load (max), so my recommendation of a 500-550w would jump to a 650-700w PSU if you go SLI.

People don't need such gigantic PSUs as they think.

Ah, ok, just checking. Someone was running low-end GPUs in Xfire/SLI and disappointed with their performance about a year ago. At least you're using sufficiently powerful cards to see an advantage.

But I don't understand the reasoning--if you end up going 2x 660Ti's, you will pay more, unless you wait for the GTX 700 series come out, when you pick up an obsolete card at a reduced rate. Even then, it's a lot of waiting at half power (in terms of what you can afford) for a marginal amount of savings.

The cheapest 660Ti is about $250, whereas the cheapest GTX 680 is $410, which is about $90 cheaper than two GTX 660Tis *and* unlike SLI, the 680 will always perform much closer to its performance ceiling (SLI is never near 100% efficient in terms of scaling).

Short of a bargain deal on 660Ti's, you'd be better off grabbing a single GTX 680.

I don't know... your numbers just don't add up. The 3750K has a rated TDP of 77w and you are only running a single 660TI which has a rated TDP of 150w for the stock version (77 + 150 = 227). So if you add those numbers up and add a bit of head room for the RAM and the HDDs it still doesn't come close to 500w (from the wall, 455w @ 91% efficiency). So some where/how you have managed to double your power draw. You have either got one hell of an overclock going for both the CPU and VGA or there's something wrong with the PSU.

According to the efficiency curve on the marketing material, the unit reaches peak efficiency at around 420w - 500w and the fans will start increasing RPM at around 60% load. So technically at 43% load, the fan RPM should be flat @ 20db.

I run a HX650 with a W3540, GTX670, 4 * 1.5TB Seagate 7.2K, 1 * 750GB Seagate 7.2K, X25M 160, X25M 80, 330 180, LSI Megaraid controller, and I can't hear my PSU when my machine is under load.

I also have an AX1200, new, that's currently sitting on my desk because I don't see a reason to upgrade (and I am too lazy to redo my cable management as it's a pain with this many components inside the case). I don't have the exact same setup as you but I can get something close if you need me to help you run some power numbers. (spare processors available: 970, 2700K, 3770K)

If the fan is really loud during your load levels it may indicate a bad fan bearing. You may want to look into getting it RMA'ed.

If you can hear any PSU fan over GPU and case fans, then I'd send that crap back in a second for an RMA.

I've never heard any PSU that's audible, even under load.
