Hey guys, bought basically a new system from overclockers UK, here is what i bought -


Product Name Price Qty Line Total
Krypton Crosshair AMD Phenom II X6 1055T 2.80GHz @ 3.80GHz Overclocked Bundle £314.88 1 £314.88
HIS ATI Radeon HD 6970 2048MB GDDR5 PCI-Express Graphics Card £229.99 1 £229.99
OcUK Crusade 850W Quad Rail High Efficiency Power Supply £47.65 1 £47.65
Seagate Barracuda 7200.12 250GB SATA-II 8MB Cache - OEM (ST3250318AS) £23.82 1 £23.82
Antec Tri-Cool 120mm Red LED PWM Fan

I have been having various problems with it, mostly, 90% of the time, the pc won't even post, the RoG motherboard has the external lcd poster and basically every time i start it, all the fans, leds, drives, usb devices etc power up but the pc wont start posting, ie pc beep/gfx card fan blast, when it does post it crashes most of the time, i am guessing it is the cheap psu to run this kind of system? The RoG motherboard has power lights by key components, ie ram, graphics and cpu, which light up to 3 power lvls, normal, high and crazy or something to that nature, when the pc boots all these lights are on normal, but 99% of the time when i turn pc on, none of these lights come on, i have tried booting with a much older and far less powerful card to see if it was my beasty graphics card hogging the power, seems to do nothing and still won't post, have tried cmos resets, static discharges, and loads of combinations of pressing buttons when booting, i wanna try and diagnose problem before i RMA my psu and swap for a better one, if that is the problem :)

TIA

Jamie :)
 
i was told by a ocuk tech representative that it should power system fine, unless he meant, technically it has enough power but no reliability?
 
Yes really.... I purchased the Corsair TX 750 after that joke of a PSU.

Which is exactly same spec as the Cooler Master GX 750W Power Supply but at a cheaper price.

PSU is your problem I flipped with that PSU in the past and only thing they are good for them PSU's is for old systems... You wonder why they are so cheap ? Now you know why... Sorry but 100% sure it's that PSU I had exactly same thing happen to me using one of them.


Send it back and ask them to replace it with the Cooler Master GX 750W Power Supply and pay the difference.. I wish they would just remove them from sale and save the customers that buy high end systems a headache and cost in returning them.

Yup no problem.. Should work fine.. That pc won't come anywhere near 650w of power used at any time, not unless you go crossfire with another 6970.
 
No harm in trying anyway, all power supplies have fail safes, if your rig did draw more than the power supply can handle it will just turn off, much like is happening now.
 
Just to add look at my system spec in my sig... My system has a 750w PSU ... From the mains i'm pulling under 400w (system at full Load/Stress) with the screen plugged into the test meter too ...
 
Okies will try tomorrow, i just made system boot with the OCuK psu btw guys, the MemOk button feature on the RoG motherboard, i have all my components in - i did the memok sequence where it tuned my ram and the pc started first time, i thought it was a fluke so tried restarting it from scratch a few times and it still working, no idea why, am running a Linx test now using all ram and cpu to see if pc is stable with overclock and this psu, even if it is stable and continues to work is a psu upgrade still worth it?

Click to expand...

Or all you hear is the fans running and motherboards LEDs light up but won't post as it did with me that PSU with 2 different motherboards.. I 1st thought was a bad motherboard RMA-ed the motherboard and they sent me a totally new motherboard only to find the same problem... Guess what then I flipped went to a pc shop purchased the Corsair TX-750, plugged it in and it all came to life with the post beeps.

Them PSU's need to have a warning on them when sold, to clearly state on them they will not power up a high end system with a high end GPU. They are only good for replacing a cheap office desktop PSU.. Not for gaming or highend rigs.
 
on a different note, on the laptop i am on atm, each time i try and run a trusted (by me) downloaded exe file, my laptop stops it from launching cause of DEP, any idea why? it didnt used to :(
