Bad / Underpowered PSU? Please Help

I have the following system:

Mobo Asus P8H61MLX
CPU I5 2400
Cooler Thermaltake Contac 21
VGA Gigabyte gtx 560 (simple not Ti) 1GB
2x dvdwriters 2xhdd 5x12v fans
2x4gb ddr1333mhz kingston
PSU NOX Urano Max 600Watts Efficiency >75% ( 2 rail of 21A and 22A )

what i've experienced. when playing Heroes 6, the pc reboots by itself. sometimes after 15 mins of playing sometimes after 2 days. i play battlefield 3 with no problems.

today i've installed alan wake, the game, i run the game, the PC makes a strange noise, like a squeak, after 10 second the PC restarts. i enter the game again, the same sound same time pc restarts.

could it be a underpowered PSU for that system? i replaced GTX 560 with 8800GT, the system was stable in alan wake and could play a bit.

thanks in advance, i already ordered Cooler Master GX 750W max 900W. Hope i don't buy it in vain. I also did an 8 hour memtest86 no errors found on Ram..

i want to add that the pc was stable in prime95, furmark and the both run simultaneous.

For a single card, non oc system it is fine, you actually should have got the GX550 (80 Bronze) rather which would have been more than enough. I use one and it is fine.


"Pile of crap" - more like capable for a specific builder, sure the 650 and 750 didn't do as well as the 450 and 550 but its better than the "crap" that was in there.

thanks davcon and sarinaide for the quick answer, i will cancel my order of that pos, but please recommend me a good one, no more than 100euro, i do big efforts to buy that because 2 week ago i upgraded my pc to what you see above. Thanks!

btw that POS i have NOX, was brought 5 years ago, but was only 400 days powered on (i read that value with HDD sentinel on my hard disk).

but it's only 520W 87% efficiency, will hold on my system? consider in the future an overclocked GPU. thanks.

i was looking at Inter-Tech Energon, there is one at 1000W Modular PSU around 110euros, isnt that better?

FinneousPJ's suggestion is great! Seasonic PSUs are very good and efficient!
1000W is overkill!

thanks for the asnweres FinneousPJ and ngrego, i was looking into OCZ PSU too, but i believe i will be one from Corsair OCZ or that Seasonic

Yes, the Seasonic is more than enough for a single 560.
February 22, 2012 8:32:59 AM

btw what is the difference between a modular psu and a simple one?
February 22, 2012 9:15:03 AM

ok, guys so i've decided, its :

Corsair CMPSU-600G 600W, ATX2.3 (1x12v rail 48A - max 576W) at 80€
or
Seasonic S12II-620 Bronze, 620W (1x12v rail 48A - max 576W) at 90€

OR should i take the modular one from Seasonic M12II-620 Bronze, 620W (2x12V1/2 rail 24A/24A - max 576W) at 100€

It is worth the difference from 80€ that is the GS 600 from corsair to M12II? Since they have the same output power.

Thanks! Alex.

Modular PSUs have sockets on the PSU so you can use only the cables you need.
Simple PSUs have all the cables attached so you must have all of them in your case.
Modular PSUs allow for less clutter in your case.
All of these are very good PSUs and will no doubt cover your power needs.
Let your budget decide for you...

Since the power supply will run the system for years, make it a good one. Many good ones listed above.

I like Corsair personally, but use others too.

As for power. Think of it this way.

I7 2600k @ 4.4
AMD 5870
2 drives and 1 ssd
4 120mm fans
4 sticks of memory
the rest is not much to say

Either way, this thing has a very hard time passing 300 watts at the wall(Prime + Games).

So overall, I would have guess even that "Bad"(and it is bad if you want to gets its full wattage) coolermaster power supply should have made it by.
February 22, 2012 12:56:48 PM

Quoted from ko8888 in another thread.

For a system using two GeForce GTX 570 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 800 Watt or greater power supply that has a combined +12 Volt continuous current rating of 56 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

The Corsair Professional Series Gold AX850 (CMPSU-850AX), with its +12 Volt continuous current rating of 70 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is sufficient for your build.

Make and model really not important big brand you could be paying for the name and not the device. Read the specs and compare with what you need. Add a bit to the PSU spec and bingo. you have your self a fix.
February 22, 2012 1:06:22 PM

What about the Motherboard's PSU (the one on the actually board all good?)_
February 22, 2012 1:38:16 PM

sigh..so much mis information on psu's...500watt is plenty..stay with good brands corsair/antec/seasonic/silverstone/xfx.

500-650 is perfect for your build and will handle plenty of OC'ing and upgrades in the future. The only time you could hit a road block is going sli on a 650watt..so you would then have to upgrade to a 750watt (which is usually enough) or a 850watt.

imo pick between the seasonice/corsair finn suggested..if one is modular go with it...modular will make your build cleaner/easier.

stop throwing out crazy suggestions like how he needs 850watt when he doesn't etc.

Personally i would drop a few fans. they are probably just making a lot of noise and using power, but not actually doing anything useful.


i did that, i let in case only 1 hdd, mainboard, cpu, cooler cpu, and gtx560. still restarts..

If prime and furmark(at the same time) ran without a crash, i am doubting you are out of power(run prime with 1 thread short of the cpu's core or thread number so that fur can work harder. in your case, that is 3 threads of prime + fur). It may well be a driver bug. Try to run one or 2 driver versions back.

If you are not already at the latest drivers, try those first.
February 23, 2012 4:04:58 AM

To be fair the power blueprint is droping, GPU's and CPU's, RAM and Motherboards will drop the drain so you can expect that a 650-750 is perfect for SLI/Xfire down the line, while a 500-600 is great for a Single card setup.

Using the PSU calculator on my build I use a max load of 444-460w on the GX550(528w@12v) with 1SSD, 1HDD, OC'd 2500K (roughly 144w), GTX560TI (202W) and 4 fans. I don't come close to any of the rails capacities and thus suits my needs not running continuous excess capacity. If you can't afford or unlikely ever run a power hungry build then don't bother with a high capacity PSU.

Also try avoid the big brand myopia that is created, I know of enough Corsair and Antecs being returned and yet highly criticised OCZ, Thermaltake, coolermaster make respectable PSU's along with some bad ones, but then again everyone does and no brand is fail proof. In my country I avoid seasonic and asrock due to the 2 year warranty, while the others are 5-7, consider that too.

i've uninstalled my latest drivers (21 feb) and put one older version (11 oct) the same noise and pc restarts.. :(

i will wait for the power supply and post here what happens after i change it. i really hope it's the PSU so i don't waste 100 euros like that.

thanks a lot to all! Alex.

What PSU calculator would that be ?
Used to be one that would calculate approximate power consumption, last I looked it had been taken down.
The big favorite today is the Outervision Extreme PSU calculator, but it doesn't calculate power consumption, it provides a power supply wattage reccomendation, that's not the one you mean is it ?

Sorry yes it is the recommeded wattage peak and regular wattage is given.

I've ordered this PSU,

http://www.emag.ro/surse/sursa-corsair-cmpsu-650tx-v2-6...

sea sonic was a even choice, even cheaper 20€, but in my country i get 3 years warranty for it, so for 20€ more i chose the one above (5 years warranty).

thanks to all for helping, Thursday - Friday i will have it, install it and come back with a reply!

Hello, it is me, i am back after 2 days of testing my new PSU. well as hopefully expected, my old PSU wasn't strong enough to power up my build so the computer in particularly games restarted. After replacing my old one with a Corsair TX650 V2, all games work stable, no restarts!

Thanks you all for the help provided!

Hours of headaches.
March 3, 2012 4:14:14 PM

i did spend like half an hour to hide all those extra cables.. and believe me it HAS extra cables!! :) )
March 6, 2012 11:30:00 AM

OK, i need a bit of help again! After replacing the PSU, all works fine but in some games i hear a strange noise / coil whine like, BUT if i force on vsync in nvidia panel the sound goes away but my frame rates drops.

what could cause the problem? should be the VGA (gigabyte 560gtx) or the PSU? (the PSU is silent doesn't make any noise, i got it outside the case, and the sound comes from the VGA)

Alex.

PS. a replace of the vga card will help or replacing the PSU?
March 8, 2012 7:34:15 AM

new card arrived, worst noise in every game, vsync doesn't fix this one. what should i do? return this as well? :( 
March 8, 2012 10:04:59 AM

I have heard stories about Corsair PSU's making noises under load.
March 8, 2012 10:43:11 AM

yes but is not the PSU that does the noise, i got it outside the case, and the noise come from within the case.. :(

It's probably nothing.

Try using a high tech hearing device, for example a roll of toilet paper against your ear, to see if you can isolate the source. If it's your GPU, change the brand I guess?
March 8, 2012 11:05:04 AM

yes, i returned the second gigabyte gtx560, now i am waiting for an msi gtx560.
March 8, 2012 11:13:09 AM

it is possible that corsair tx650w v2 doesn't deliver enough power to the gpu? and that's the reason that it makes noise?

No, it could run 560 SLI.
March 8, 2012 11:21:12 AM

i am not sure CM referred as very good brand. Personally i d go with corsair (7yrs warranty for HX,AX) . But they will cost more. Depends on your needs

This is what you are going to do, you are going to isolate the source. Download furmark and run a GPU burn test, when under load you are going to listen to isolate the noise, it is very common that such is the PSU, and Corsair has a history of this. In terms of power the TX650 is in fact to big for your needs, underpower is not an issue here.
