Bad / Underpowered PSU? Please Help

[Nattefrost]

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..

Alex.

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

Sorry to say,but you've replaced your pos unit with another pile of crap.

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.

 

[Nattefrost]

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).

Where are you buying from

 

[Nattefrost]

yes i buy from here:

http://www.emag.ro/surse/stoc/filter/putere-sursa-w--m634,intre-500-si-79999-i204/pret,intre-200-si-500/sort-priceasc/last/f1

i know it is a romanian website, but i enable some filterss (500-799W and price 50-120euro) only surf between the pages, thanks a lot in advance!!!

 

[FinneousPJ]

Here's a unit that's going to be with you for years: http://www.emag.ro/surse/sursa-seasonic-s12ii-520-bronze-atx12v-520w--pS12II-520Bronze%28SS-520GB%29

 

[Nattefrost]

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!

[Nattefrost]

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

 

[FinneousPJ]

Yes, the Seasonic is more than enough for a single 560.

 

[Nattefrost]

btw what is the difference between a modular psu and a simple one?

 

[Nattefrost]

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...

 

[sarinaide]

I would consider this;

http://www.emag.ro/surse/sursa-corsair-cmpsu-650tx-v2-650w-atx23--pCMPSU-650TXV2

got some extra capacity and good build quality and warranties. That said on your build you would have more than passed on a Coolermaster GX550 with plenty to spare.

 

[nukemaster]

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.

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.

 

[davidgermain]

the spec of you current PSU form the manufactures site are...
http://www.nox-xtreme.com/products_uk.php?cat=2&type=0&id=25&op=1

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.

 

[davidgermain]

What about the Motherboard's PSU (the one on the actually board all good?)_

 

[hotthree]

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.

 

[of the way]

Just to back up Hotthree...

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

 

[nukemaster]

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.
