puter problems

[cobalt6700]

ok...so my mate harry purchased my 6800gt off of me...

he is running a p4 3.0 Ghz, not oc, the 6800gt, not oc, 1 HDD, two DVD drives, XSPC watercooling kit and a sound card....

all on a 300w PSU.

since the GFX has gone in, his pc has gone really slow...and i thaught this might be becasue of lack of power (ive never had a problem like this before)
hes running win xp

thanks in advance for any input

Its ok without the gfx card? Can you swap PSUs?

[cobalt6700]

umm well not as such..


but he can run the GFX off a second PSU

is it worth running some kind of driver cleaner and reinstalling the drivers?

[Crunch]

Worth a try I guess?

[Greeny]

A good 300W PSU or a dodgy one, theirs a fair bit of difference? Sounds borderline though I'd go with 400W or better for that setup.

[cobalt6700]

dodgey one. jeantech. or something like.

dosnt look up 2 much.

could it make his PC slow though?

[Greeny]

Yes it could.

will cause computer too crash also.

i had a 460 installed in my p4 2.4 no OC'd, gf5600 OC'd, 700mb ram, 1 dvd rom,1floppy,4usb addons,7 fans (inc cpu/gpu), fan controler, 2 uv lights. one evening the rig realy started crashing, just starting counter strike source would cause machine too lock up,the speakers would whine/scream. i did'nt do much about it untill i smelt smoke and noticed a cool smokey look inside my case. yes psu gave up its last breath.

a new psu/more watt psu would be better. too what i can gather a 6600/6800 needs a min of 300 watts and rather likes 400 too be safe. i think he is pushing the psu a little too much causing everything too slow down because of the low power

hi guys, im that cool harry dude gaz is talking about lol. yup, its all true, crappy jeantech psu 300w peak load! i am soon to be buying(hopefully) something like a hiper 580watt modular which should sort things out! But anywho, i have unplugged opticals, all pci cards, cold cathodes/neon strings, case fans(dont worry, all side panels have been removed hehe), fan controller and lcd screen. so now all i have is the w/c system, hdd, graphics card, and mobo/cpu being powered. it seems to be running better now, so i will leave it like this until i aquire a better psu.

But i do have a spare psu, is there a way i can run the system off the 2 psu's without going inside them and making relays and stuff? what problems could i occur if i say plugged the graphics card into one psu and the rest into another? i assume i would have to turn both psu's on at exactly the same time?

any comments appreciated thanks

p.s oh by the way guys, great forum!!

You'll struggle to use 2 PSU's on one system without the use of a relay to 'kickstart' the 2nd PSU. Your main PSU is brought to life by the psuOn wire being shorted to ground which in noraml operation happens at your motherboard when you hit the power button. Unless you can find a way of doing that to two PSU's simultaneously then we're starting to talk about a very fiddly setup - probably one that's a little unstable too.

In short, do the relay mod if you want 2 psu's otherwise get a bigger unit.

[CandyKid]

Just use one PSU, it'll save you a lot of time and trouble.

For a good PSU, go with PC Power & Cooling, Tagan, Sparkle/Fortron/FSP, or even OCZ. Those are top-of-the-line.

Also, STOP USING THE COMPUTER WITH THE 6800 IN IT!

Until you get a bigger power supply, you risk frying everything in the system. Yes, your components can die b/c of dodgy power or over-stressing the PSU.

The slowdowns are probably due to a CPU slowdown and/or PIO modes and/or auto-safe frequencies on the memory as well. All good indicators of poor power.

Dont some of the 2 PSU cases just have a pass through adapter (think like a 24-20 pin ATX adapter) with a fly lead running from the green and black wires to a female ATX plug? You could get away with one of those if you can find one

hally!

:D

edit....ill get you your mx460 back untill u get a new PSU then mate :lol:

[hazza2805]

ok guys, thanks for the advice! i have put the mx460 back in for now, while i await a new psu. i am about to order a hiper type r 580w modular power supply. every review i have read is good and it seems perfect for what i need.

if any one knows anything that could help me, such as any bad experiences with that psu, and anywhere cheaper than ebuyer for it, i would be much appreciative!

thanks

harry

Have the very same TypeR supply to match my motor! - works really well, despite some people on here slagging it off.

The problems were def. down to PSU imo. :thumb:

[Greeny]

Not a bad experience with that one, just with one of their older model and to be fair it works fine, but the fan clicks loudly. Very annoying. This was also reported by other users.

Clicks? Do you mean like a repeated clock-like tick or a iregular periodic sound like washing machine 2 doors down?

Mine is the later, cant really explain the sound.

[hazza2805]

so is that a problem alot of people are having with the hiper?

Repeated tick-tick-tick, bearing in bottom fan was of low quality. Oiling the bearing stopped the ticking, but that only lasted an hour or so then it began ticking again.

[InigoMontoya27]

Yeah, a while back when I got my new Radeon 9500 it required a 350 watt psu and I had a cheap 350 watt max psu. At that time I was using air cooling with a lot of fans. Worked for a while then the system just shut off, dead power supply. It's really not worth it, I got lucky and only toasted the psu.
