Hey guys!

I got a brand spanking new 8600GT the other day, nice card, runs everything I throw at it high details etc. at 1280*1024 ( Monitors max resolution...)

Anyways, I ran it on my 300W PSU that come with my box, it's a FSP. No major problems, but every now and then the system becomes unstable, reboots etc. But this is only after quite a while.

Anywho, so I thought I would buy a new PSU, just to be safe. Got a cheap 350W one for like R250 or something. Doesn't look dodgy or anything. This was yesterday.

So I popped in the new one, fired up my pc, took a look at the voltages and all looked fine.
Then I fired up a game or two, went alright, for about an hour, then when the action starter, read there was lots to render, load from disk etc. the psu made a nice "pop" sound and there was a nice blue flash I could clearly see through my case window.

I'm not sure what would cause this to happen though, maybe it can't deliver enough power? Gets strained too much?

So today I went and got a replacement, no hassles, the guy at the shop looked quite surprised.
I thought it may be a factory error, just maybe.
Popped the new one in an hour ago, same thing happens.

The moment the pc gets very busy the power supply pops.

Okay, now here is the strange thing, it doesn't run bad on my 300W PSU, like I said, no real problems, but when I have a bit of a marathon session, it gets unstable. But still, played through the exact same scenes on my 330W PSU and it gave me no problems.

Can anyone please advise as to what may be the cause of this problem. It is definitely not an electrical fault in the house, as two other pc's were running fine at the same time.

If someone could give me an explanation for this I would be very grateful.

PS. I'm going to ask for my money back tomorrow. Are the AOpen power supplies decent? Because that is the only other ones I saw in the shops at reasonable prices.
 
Need your PC specs to make any sort of useful comment, but honestly anything less than 400Watts is a waste of time and money. Also dangerous to your hardware...

The Aopen 400Watt is a good unit for the price and you should start there and go forward. Forget about 300Watt PSU (Unless its a PCP&C, but then...)...
Prophecy used to have or I gather still have some Huntkey 450Watt units, much much better than FSI or whatever else was at that shop. (Save for the Aopen which is good)
 
Sorry for sort of hijacking it....

What size PS would be good for a QC6600 + 8800GTS 320mb and 2 x hdd and normal other stuff?

Yeah, I figured I should get a 400W, but couldn't find one in the stores and didn't want to drive to joburg. But I found one at BTgames, so will go buy that today.


Anyways, I have: Athlon 64 3500+ (Venice)
1 Gig DDR 400 RAM
8600GT Factory Overclocked (<Why I wanted the new PSU)
80GB HDD
DVD-Writer
Two 8cm fans.
Some nforce mobo, micro ATX.

I think that's about everything that draws power :)

Thanks for the help ShockG!

Sweet, thanks a lot man, I tracked the AOpen 400W down at BTGames. Will go get that today then :D
 
Yip, ek stem saam met ShockG slikkie, daai PSU is veels te klein maatjie ;)
 
Schweet, thanks a lot guys!!!! Of to the shops right now :D


Heloooo tera jou rakker!

Anything above 500w should be fine, but make sure you get a decent brand i'd recommend Antec.
 
Brawler how do you say descent brand then say Antec? :D
Overpriced and rather average for the most part. Get Enermax, Raidmax, Seasonic or the likes. For the cheaper brands look at Aopen or if you need it cheaper but working good get the Hunteky or Omega 600Watt.

just keep in mind that split 12V rails are rubbish, get one good 12V line of atleast 32A and be happy
 
Notice how your 300 Watt, probably a better quality part, could run things okay, while the cheap 350 just died.

I've got a very similar PC to yours, that would draw just a bit more power, and my Asus 350 Watt that came with my case works fine. I guess it's reasonable quality, compared to the cheap junk that goes around when it comes to PSU's.
 
Yeah, never buying anything without a name I know and trust on it again.
Cheap low quality crap.....

Thanks for the input guys! I went and bought that 400W AOpen PSU. It's working good, doesn't even become very warm.
