Hello. I find myself in need of a bigger power supply than what I currently have. It needs to still have the intake fan to suck in air from the cpu, and it has to be relatively cheap.
I've been looking at some units from coolermaster and corsair. Normally I just default to vx450 for normal computers and hx520 when I build gaming systems ... but for myself I need something bigger. Dun have any good experience with the bigger units.
Any reasonable suggestions? remember pricing is important. Still recovering from car repairs and dentist bills.
Edit: And more importantly than anything else - it has to be modular. I'm using a custom case I built, and I do not have room for a ton of spare cables. I only need two molex, two sata, 2 pcie6 and 2 pcie8 connectors after all.
You don't get "cheap" PSUs if you need a lot of power.
Corsair HX850 will run pretty much anything short of Fermi SLI
Custom desktop case. 3x 120mm Arctic Fan 12 PWM intake fans, no lighting other than the motherboards voltage and heat leds
i7-920 @ 12-21x115 (1380-2415mhz) normal and 12-21x181 (2172-3801mhz) when gaming
Gigabyte GA-EX58-UD5 F10
Sapphire HD4870 512MB & Club 3D HD4870X2 2GB
6GB Corsair XMS31600C7 @ ddr3-920 5-5-5-13 normal and ddr3-1448 7-7-7-20 when gaming
TR120Extreme & 2x Arctic Fan 120 blowing directly out the back of the case (open hole)
2TB hitachi 7200rpm system & 2TB WD green storage
Corsair HX620 & Antec Earthwatts 380 PSUs

I have an idea of adding an amplifier card internally and scrap my old surround system, so I might need 100-150W more than the specs otherwise suggest.
Power calc sais 843W recommended. So I'll probably have to go for 1k rather than 850w. I've looked at the 850w coolermaster unit, but it might not be enough.
Which brands have good power supplies other than seasonic? (don't say ocz or I'll kill you)
I can get just over 600W without overclocking.
But since my psu started making wierd noises after stressing the system, clearly I'm using more than 600W. And in fact my wattage meter told me I was using over 700W (from the plug) at some point under 'normal use' so 600W really isn't realistic.
Anyway, I'll hope for someone else to drop by with recommendations. I like corsair, but I'm not sure they're the right choice in the high power marked.
As for the amp, no I can't give any examples right now. Haven't had time to google the unit I want, but once I read a review or something about htpcs or whatever, and there were pci or pcie amplifiers which delivered about 60-100w per channel directly to speakers. It's been a while, so I don't recall the actual review, but I would like such card.
I simply don't regard corsair as a top quality brand. They're good, but I'm not convinced they're that good.
I use corsair exclusively in every system I'm building for other people, but I've yet to ever use a bigger unit than my hx620. And appearently there's no sort of overload protection on those units, and judging from my only unit that I ever stressed, they're not built for more capacity than they're rated for. At least not on my unit (which is just under 3 years old).
Anyway, since I've only had one corsair unit failing, I'm not going to claim this is a general thing. I'm just not confident in them. Also the annoying noise comming from them when the computer does playback of certain video sequences is annoying. And I've experienced that noise on every single system where I've tested. Anywhere from the cheapest vx to my 620 unit.
so you haven't experienced the noise issues ? how many corsair units have you tried?
It's specificly intro videos on many EA games that cause this noise. I can't recall a specific title at the moment though, and since my unit is broken I'm in no position to test it right now.
they are semi modular they are specially made for antec full towers as you can see they are larger then normal atx spec power supplies but since you having the case made the fit shouldn be a problem
Since my case is custom it was a problem.
I built the case for my opteron 170 system in 2006. Back then I had a standard size psu.
The coolermaster psu I settled for only just has enough room. Think if I'd taken the antec I couldn't have closed the lid or connected the dvd drive.
The fan's making some sort of ticking noise that is clearly audible even at range.
The other day I was standing in my hallway with the doors to my hobby room and the livingroom open. Approx 3 meters away was my server in the hobbyroom - I couldn't hear it. But I could hear the silent pro ticking away at the other end of my livingroom. I'm not sure how far away that is, but definetly futher than the server.
It does deliver power nicely though, and doesn't seem to run hot even under load. At least not in contrast to the 4870x2 which I measured at 54.3C on the outside of the top most cooling pins.
