Ok. Good news after 4 odd weeks hiper have sent me a replacement power supply. So i now have everything i need to get my computer working or so i thought.

My problem is that when i turn on the computer via the on off button on my case, with all the cables plugged in, it powers on, then powers off. To rectify this, i can take out the 4 pin cable for the motherboard. This means that it wont boot. However when i do the green/black cable pin trick, i can leave the 4pin connector in, and it turns on fine. However this means my motherboard is not getting power.

What's the cause and solution? :confused:


thanks, alec
 
I've heard of some hipers having a "4ms power cycling" fault... you could've been given a hiper with that fault? Do you have another power supply you can use to test with (just for 5 minutes to see if it boots without turning off again)?
 
Nope, as the last power supply i had i sent off to be fixed, and they sent me a new one. Ill give them a ring now.

EDIT; how sad am i, ive rang them so many times i remember their phone number
 
They've told me to contact DFI, as they refuse to believe that it is their fault. Anyone have any proof of this 4ms power cycle happening. Might be useful.
 
It's difficult to find whats wrong without another PSU or mobo... Searching the forums I can't find the guy who posted about the hiper power cycling :confused: I'm certain someone mentioned a hiper power cycling every 4 milliseconds or something stupid.

Maybe you should send both the mobo and PSU back to whoever you bought it from, so they can find which is faulty.
 
best thing you could do to prove its the psu is to buy a cheep psu, plug only the needed items in like the main hdd and such.

see if it boots, if it does, tell hiper this, if they do nothing you can get your money back i do believe either that or they have to give a replacement one as the item doesnt do its job.

What mobo do you have and are you talking about the 4 pin square or a normal 4 pin molex connector on the mobo?
 
Check the main PSU to mobo connector and the 4 pin square mobo connector to make sure that none of the connectors are being pushed up and out of the socket when you plug them into the mobo.
 
made a bit of a breakthrough. I decided to change my cpus over (opty 165 to athlon 3700+) and it now powers up for a bout twice as long.

My logic is telling me that because an athlon is single core, it uses approx 1/2 power, therefore lasts twice as long before cutting out.

i just received this email from hiper:

"Dear Sir:

After looking over your specs I think I see what the problem is. The 580 watt PSU is simply not enough for this config. The 8800 videocard you are using is demanding as well as the motherboard itself. When the system shuts itself off like that it is very likely that the overvoltage protection on one or more of the rails is being tripped in the PSU. I would advise an upgrade to a PSU in the 800 watt range. I believe that Hyper has a number of models that will fit the bill so I'm sure they will be able to supply you with what you need. Other good brands are PC Power & Cooling, OCZ, or Corsair. "

i dont think that i will need an 800watt, ive found a very nice 600w or 650w, what you all think
 
have you tried removing the graphics card and seeing if the mobo beeps ???

if it does then it might sugest not enough power.

dont believe what they say, test it out.

if it does start up and beep then you know there might be not enough power.

just tried it without the graphics card in. Still turns off.

i have emailed the support guy back saying the pc still turns off with out the gpu. i also mentioned that the brand of psu he recommended (corsair) dont do a 800w psu, the amount he recommended

This is ridiculously fishy. This is unacceptable behaviour on their part. The previous PSU powered the system before it's untimely demise.

I would total up the values using an online Power Calculator and see what you really require.

I suspect you should be well within budget.

Then try with bare components. 1 stick of RAM, no HDD, no CDROM. No extra cards.

Take a note of that new PSU budget and it's failure to start.

Then present your evidence to Hiper.

[edit]

Dammit that PSU calculator used to be free, any one know of another good free alternative?

That seems to be ok.

i just put my system in that calculator and it says i need 960 and i had to choose a geforce fx5600 instead of my gpu... so id say it isnt right

ok well if your system booted fine with the same wattage psu before there should be no problem,

however i would try removing all no esential items such as extra harddrives and swapping the gpu for a less power thursty one :P

then if it doesnt boot show hiper the finger and demand a replacement as it obviously doesnt work.

or you could try using it on a diff system eg older one to see if it boots that.

it says i need 517 watts. although to be honest im sick of hiper so i will just get a corsair 620HX. I have a friend who can get me a goodish deal

Edit: infact he cant :mad: so which is better out of these:

Tagan Dual-Engine 650W PSU
Coolermaster eXtreme Power 650W PSU
Seasonic S12 Series 600W

Does the Sli-Dr have a 4 pin molex slot on it? If it does try removing the cable. Iirc the sli-Dr shoud have an led post code. What does that read?

You could also try Dfi-Street (or whatever it's called now). Another helpfull thing to do would be to disconnect all the bits. just leave your cpu in. Try booting. if that doesnt work then you know it's either the mobo or the psu.

If it works then add a component at a time till it fails to boot.
 
It is diy street. I posted there, they were the ones who told me my psu was bouncing. The LED code is all 4 red, however i know it is not the cpu as i have tried two different cpus and also the LED code stays red until you post

And don't give up on Hiper RMA - don't let them get away with this ridiculously poor service.
