(System specs below)
Yes another power supply issue, but I wanted to get some opinions based on experience and also alert any googler's and the like of PSU's that won't suit them if there set up is anything like my own. Unless of course through this someone detects I might have an issue somewhere else.
EZcool 650w PSU from scan. Sli ready ( with 2 PCI-E plugs ). Runs 3 days on my new set up, I run a bench mark or two, GPU's get quiet warm as expected but all running fine. Then that smell of subdued burning - " alas it is just the system settling in " I say to myself. And out the power goes, total shutdown. Cool everything off, restart, Reboot fine. Try running for a while, bam, shuts down again. Now that PSU will power the board ( as in light it up ) but won't turn on. Here is why ( maybe ):
Multi meter tests of this PSU:
- Yellows - 8v
- Reds - 6v
- Orange 3.3v
- Blue - ( minus/negative ) -14
- Grey - 1 and 5 respectively
Not right is it ? So my guess is the Mother Board will not power up as there is not enough power to start with.
So in haste I order an unbranded 850w Sli capable PSU from 'The dreaded ebay !' , I won't say who the seller is, but its an AlphaPower 850w psu for around £35. Yep I know - and I have learnt my lesson now.
It was in for about 4 hours, I was going real easy on it too, tried an easy low grade benchmark, powered off, had to turn on again. Then I was simply downloading a patch for STO truth be told. Then BANG !!!, nice blue flame out the top and that fabled smell and half way to spoiling myself in the process.
Looking inside the PSU through the vents in the casing I see the fuse gone and I hear rattling inside. I've asked the seller NOT to replace the PSU but refund me as I hope scan will do as well - though I know how they like to fight these things " It works perfectly Sir. If not its your fault, you must have done something wrong - we cannot possible have faulty components on sale - the ones we never test and stare at on the shelves until someone buys it " etc etc. Not looking forward to that.
But in any case, the EZcool died, though thankfully not so dramatically. But can it truly handle SLi ? NO !
The Alphapower 850w, can that ( even with all the cables and plugs it has, quiet a lot actually ) handle Sli ? CERTAINLY NOT ! And that may well have taken half my other components with it. Never touching one of those again for sure- HIGHLY DANGEROUS I feel. If I had my head over it, or a child or cat ( yes I have a sick sense of humour ) there would be a mix of burnt odours when then that PSU blew !
So my lesson is, 650w Sli by EZstool, not up to the task. AlphaPants 850w Sli ( a mere 10amps per rail, seriously ? But correct me if I read the specs wrong ) most deffinately not up to the task. Be warned ! And be safe !!
I am now looking at the other end of the spectrum, something like the Antec 1200w Truepower Quatrro ( noting they have some extra bits on the leads to ensure stable Sli/X-fire loads ), a whopping £150+, but one would hope that when running something, you will get what you ask and not a strong chance of the fizz-bang " OMG ! " moments.
Something to add ( for the sake of it ) I've noted sometimes when a shut down happens when trying a cenchmark ( IE Futuremark stuff and Crysis ), switching Direct X has stopped it happening. IE DX 11 or even 10 on Crysis and the system would shut off, but set to 9c and it would be OK. Not sure if thats coincidence or not though.
But in any case, when you ask the PSU to supply ample juice to the GPU's..... be ready for a surprise - we hope a good one !
Any thoughts on suitable PSU's, let me know. Any other thoughts - add away as this may help others too later on.
( My newly built but seldom used - yet - system which is in no way Overclocked I must add, all stock settings for now ):
- A+ twin 250mm fan, 256 colour case ( you can turn the fans and/or lights off by the way ).
- Empty space where a DECENT psu needs to be, some burn marks around that area now included.
- Gigabyte 990FXA UD-7 Mother board on the 10b Beta Bios ( STILL throttles my memory back and slows down my SSD ).
- x2 Gainward Nvidia GTX460 768mb cards in SLi set up.
- AMD 8150 water cooled.
- Gskillls Ripjaws 1866mhz 16gb ( x2 8gb units, running at sub 700mhz thanks to the bios, grrr )
- Kingston hyper X 3k 120gb SSD ( should be at 6gb/s but benchmark says a lame 82mb write speeds ? )
- Pioneer BDXL quad layer Blu-ray drive
- Equiped with multiple curses laid upon it from gigabytes Bios holding my memory and SSD right back, and the PSU conundrum thats wasting a lot of my money with no results - heck I've not even had 10 minutes of stability to try a game yet ! )
NB) I contacted Gigabyte about the memory and SSD, the reply ( literally and I quote ) was " Download bios 10b beta, set memory to profile 1 ". I got about 100mhz more to the memory, no change to the SSD.
