PSU Cut Off!

[DJ Tucker]

ok, so i have now read about why some guys have high idle temps on their graphics card and from what i discovered this is fixable by:

getting rivatuner and clicking on customise driver settings then system settings and click on 2d performance. you will see that you 2d performance is what ever your graphics cards factory spec is and from what i discovered anything 2d will not need much in fact any power to run. so in this case set your core, shader and memory clock down to what ever you want and you will get the same performance but cooler graphics cards.

if i am wrong please let me know.

[InspectahACE]

I'm not entirely sure myself but I don't think that is the case. I remember how the 2d clock used to be way lower than the 3d clock..but that was around the FX5600 days..I don't think it matters really unless you're running MAME or Doom lol..im probably wrong though

[DMB2000uk]

You just need to bump up the idle fan speed if you want a cooler graphics card at the desktop useage.

i have tried that and nothings really much cooler, maybe bout 1c lol. i did do a passmark 2d test. when my 2d was at factory 600/1500/500 i got 628.9 and when i underclocked my 2d settings to 300/750/250 i got 628.6 and my cards are much cooler like instead of 54-55c idle i now get 48 idle and no perforance differance.

I've had corruption in the past playing with my 2D clocks (and not raising them either). Really why does it matter if the cards are idling at 50 degrees C as long as they are stable? As far as I am concerned stable is stable. Believe it or not 2D clocks do help, go to flash heavy site with an older system and you'll see what I mean.

Other than raising the fan's RPM if you are that concerned with temps buy aftermarket coolers.

[DJ Tucker]

i have no room for a cooler, i mean my cards are very close together. also another problem, the new game necrovision is not a bad game just painkiller but more graphical, only problem is that my computer turns off without notification. could this be due to the game being very graphical demanding and too much power being needed for what my psu can handle.

my psu has 2 12v's and they say 22a 12v1 and 22a 12v2, would you say this is 22a each or 22a altogether as i understand that my graphics cards configuration needs 28a in sli. if this is true can anyone tell me where to get a good quality psu with at least 4 high amperage 12v rails and for under £100 also i live in the uk.

[skier]

22A Each, and that should be fine if the PSU has PCIe connectors, if you are using converters its a different story

i like the fact my unit only has one massive 12v Rail instead of a bunch of smaller ones, i don't have to wonder how the amperage is allocated

[DJ Tucker]

mine has 2 pci-e connectors but still turns off i'm not sure why so could anyone let me know. also what wattage is your psu and what size 12v is it m8?

[Major_A]

You want more answers start a new thread. This game has issues. I would go to throw a lantern and the game would lock up my system. It would lock it up to the point where I would have to hold down the power button to restart it. Pressing the reset button would not allow the computer to reboot. Given that problem alone I am waiting on a patch to resume play. If there isn't a patch then I won't get my feelings hurt.

Weren't you having an issue about a month ago and a few of us recommended you get a new PSU?

[DJ Tucker]

yes but no one gave me a decent psu to get that is under £100. it would be nice to get one that has a decent amperage on the 12v as then i can play my game without cut outs.

thx!

[Major_A]

Give me a link to the store you would buy from and I'll point you in the right direction. I don't look at UK stores or prices so I will need a starting point.

*EDIT*
I finally broke down and looked up the specs on your current PSU. I feel like I should roll up a newspaper and hit you with it and say no.
Link To Ezcool 800W

+3.3V/32A, +5V/35A, +12V1/17A, +12V2/16A, -12V/0.5A, +5VSB/2.5A

Where you see the bold is where Ezcool is making up most of those "800 Watts".

Also...

Efficiency 40%

Ouch. Why would Ezcool even allow them to post that? I don't understand (well I do, it's money) why people spend all kinds of coin on a high dollar system then skimp on the one part that has the potential to kill everything inside the box.

*EDIT II*
Don't just look at the rails, amps, etc... Look at the brand, build quality, efficiency, connections. Things that are actually important. I'm sure that all of us were suckered into the whole more watts is better in the past but hopefully you won't have to learn the hard way (i.e. your PSU blows up).

And just looking at your system specs in your signature you could probably get away with running a QUALITY 450W. I wouldn't recommend it but that is just to show you that more watts is not the end all be all.

lol well thx for the rolling newpaper hit. so why is my psu so bad as it looks ok from where i'm sitting but then game play with it is pants. and thx dan for the links.

EDIT: i have found a different psu that i like and it is Gigabyte Odin GT 800W Active PFC PSU, Software Control and for the specifications http://www.techwarelabs.com/reviews/Pow ... ODIN-800w/ so let us know if that is a good one or not. this has 4x12v, 12v1 and 12v2 have 18a each and 12v3 and 12v4 have 25a each and with my current set up there should be no problems. so what is the extra 2 12v's for as i only running sli, although i do understand that if i go into the 200 series i will need more power so would the 2 25a 12v's be used instead of the 2 18a 12v's when i do upgrade.

[DMB2000uk]

PC's made in like the last 5+ years draw most of their power from the 12v rail. So they don't need huge 3.3v and 5v rails.

Due to how the wattage on PSUs is a combined total, some of the more shadier PSU makers will still make PSUs with huge 3.3v and 5v rails (in full knowledge that modern PC's wont utilise anywhere near it all) to make the PSU sound better than it is.

This is my first recommended PSU:
Corsair 620HX

This is my second recommended PSU:
OCZ ModXStream 600W

Third:
Coolermaster Silent Pro 500W Modular PSU

In order of preference and capability.
(I'd normally only recommend the Corsair, but you might not be able to justify spending so much on a PSU (even though you need to spend to get reliable quality), so I've given some less costly options)

Corsair TX650 £78.76inc vat
See my sig. This is what powers my PC. At one point I had my older 8800GTS in this PC (to run as PhysX) all run off this power supply without it breaking a sweat. The options that Dan listed are also excellent.

Of the 3 power supplies Dan listed do you notice a common trend there? Here I'll give you some time to think about it. "Plays Jeopardy music." All three of those of those units focus on delivering good power and nothing else. They don't have UV reactive paint jobs, LED fans, acrylic panels, etc...

[ibleet]

I have to agree with Dan. I have nothing but Corsair and OCZ PSU's and have zero issues over the past 3 years.

[DJ Tucker]

right well thx very much guys i will keep you all posted on what i end up getting.

[DJ Tucker]

is there anyway that anyone can find a single rail high amperage psu that i can get and also be able to upgrade with it in the future for whatever price you can find.

[DMB2000uk]

What are you planing on upgrading to?

The Corsair 620 HX can handle quite a lot of kit, but obviously has its limits.
