Hi

Ok so today was busy for me . Was playing CS: Source and BANG! Pc went dead, my UPS started beeping like mad .... WTF said I!!

Long story short, PSU (Enermax 620W Noisetaker) had blown . Machine deaded!

Stripped it out and it stank .. feared the worst that everything else could be shot so I headed into town and bought a new 700W PSU (largest I could find!!)

It had the 8PIN PCI-e connector (previous PSU didnt) so put that in along with the 6PIN and up she powered , everything seems fine so far.

Noticed that i know had the overdrive option in CCC but havent enabled it yet.

Ran 3D mark for the crack, and am getting a score of 17474 3DMarks which is nice and up 400 from the 8.2 Cats

So anyway , just a note i suppose to anyone running a similar spec to mine , that a 600W PSU might not be enuff to drive everything ....

Q6600 2.4GHZ @ 3.4GHZ
4GB DDR2 RAM
Asus 3870x2
Asus PK5
1 x SATA II 500GB HDD
2x SATA II 250GB HDD
 
Running very similar spec to you with a 600W OCZ and no sign of any problems...

Might just have been your PSU's time to go.
 
On a 500 watt Enermax and no problems so far here.But i only have a C2D @ 3.0 but have 2 hard drive's and 2 cdroms fans etc.Like said think it was its time to go.
 
520 Corsair with very similar system and no problems as well, as said it might have just been your PSU's time to go.:(

If my rig blows up tomorrow though I wont be happy. :(:p
 
Hey

Yeah cool . I hope your right ..

The Irony of it all is , I ordered a new Enermax 1000W last week from OC (should have it monday) and was going to take the 600W out of this PC and put into into a second PC I was building for work .....

Perfect Timing eh ?

Matey, my Enermax NT 600W has been heavily tortured for 2 years, no problems at all:) I had 2 Optical drives, 3 HDDs, 4 fans, 1 CM water cooler and E6420 with dual 8800GTS G92(Sold one now).

I do think your problem is an exception and I do think Enermax have very good CS. Why don't you try to RMA it?
Maybe your 700W is worse than your 620W:) (or give me the model name and prove me wrong:))

Well its about 3 years old at this stage so i doubt they will take it back ;)

The new one I got is a Storm 700W (Jeantech)

I am sure it will be fine , will be swapping it out again for the new Enermax when it arrives.

As far as I can remember, Enermax PSUs have 5 or 6 years warranty, right?
Jeantech is not so bad but can not level with the mighty NT:) You could compare the figures in the wattage tables bettween the 2 PSUs:)
With so many expensive components in your rig, I think this would be better. Or if it's too expensive, this TT Toughpower is also a very good choice:)
 
People massively over spec PSUs, get a power monitor and you will be suprised at how little they draw.

To suggest that rig blew a 600W psu due to drawing too much power is fantasy.

For example my system at peak is drawing 280W.

Agreed, just read an Article about this a few days ago. It claims most systems even with SLI setups only demands 500W from the PSU in maximum.
However, it's always make people feel better and safer when we know there's still some headroom left. Especially you have to take the efficiency of the PSUs into account. For example, my Antec 650W has only 624W efficient continuous output.
 
I agree that people go overkill when choosing a PSU.

But an overclocked q6600 can draw over 200 watts, plus another 250+ or so for an overclocked 3870x2....then motherboard, drives, fans.

To suggest that all he needs is a 400w PSU is wrong.
 
I think 400w is a bit off because your assuming the psu is perfect and his machine will never draw max watts, maybe but why spend all that money to skimp at the last stage & have to wonder why its not stable
600w should be fine I agree

Ive run a 300w psu for a conroe system and it was a really cheap 5 year old psu too, card was a 8600gts. Was ok 90% of the time, 10% it just hard reset in the middle of games and screwed the hdd os ..

There is no way your system needs 600W, more like 400W

Absolute rubbish. Name a 400w PSU that has 40A+ on the 12v rail? I don't think you appreciate just how power hungry a dual GPU, quad CPU, 4GB RAM + 3 HD system is, and the immense strain they will put on any modest PSU when run 24/7.

An overclocked 3870 X2 and an overclocked Q6600 will absolutely cane a 400w PSU, no matter how good quality, and that's not even when you take into account the varying quality of internal components that are used even in reputable brand names. I agree that people often buy PSU's that are hideously over-powered, what with all these 1000/1200w monstrosities appearing on the market, but to say that 600w is over the top for that syste... not a chance. I wouldn't run the OP's spec on anything less than a Corsair HX620.

Exactly, the 600w rating for example is its peak load. There's no way it would run that for long at a constant 550w for example.

PEAK can't be maintained reliably.
 
Have to say - good on Enermax. You know it was a good PSU when it went BOOM and didn't fry anything else.
 
I had an enermax take out everything in my PC (620w liberty) when it died. Its a bit hit and miss whether your pc survives or not imo.

I had to laugh at the 400w estimated power usage for his rig. A 3870x2 alone will draw 350w peak. Stick a minimum of 100w on for peak usage for the quad (at stock no less), then factor in other hardware and you really should be looking for a 700w minimum tbh for a high end rig. That or invest in fire extinguisher shares.

I personally have a 1kw psu, sure I don't 'need' all that power but I like to know it aint running at its peak output constantly and thats its well within comfortable margins. Having said that if I get another 3870x2 then I may have to upgrade it:p.
