Silverstone Strider 600W SLI Problems

Ok so here is the problem I am experiencing and the steps I have taken so far:

My system will randomly completely shut off during intense 3d Apps like games or the Luna demo.

I am running these specs and everything is brand new with a fresh install of windows. Nothing is overclocked at all.

DFI LANPARTY UT nF4 SLI-DR Expert
AMD Opteron 175 Denmark
2x 1GB Mushkin Redline PC4000
2x BFG 7800GTX 512MB
DVD-RW
WD 74GB Raptors
Creative SOUND BLASTER X-Fi Fatal1ty
Silverstone ST60F

So far I have run Prime95 overnight for 12+ hours no problem. I am also currently running just one of the GTX's to see if possibly one is defective. I don't think this to be the case though, since usually if a vid card is defective, it is defective.

I have checked the system for heat issues and there seem to be none. Both GPUs never break 60C and the the CPU is never above 50C.

What has me stumped is that it seems to only happen when running SLI and very intense 3D Apps.

Now I have an SLI certified PSU with plenty of juice.


Does this sound like the PSU is bumm? I have read somewhere about crossloading issues with the Silverstone, but I do not think I am drawing over 30A on the 12V rails.

I have also tested both cards individually without issue in either slot.

This HAS to be a PSU problem. Am I drawing more than the rated amps?


24Pin ATX connecor is using 12V3
4Pin Molexes use 12V4
SATAS use 12V2
EPS12V 8PIN uses 12V1 and 12V2
6PIN PCIExpress Connectors use 12V3

For Max Load:
12v1 13a
12v2 18a
12v3 16a
12v4 8a
 
what Id do is drop the ambient temperature and retest
depending on where you are open the window, pop the case covers, break out the parka and replicate the issue

since all supplies have a deratng curve, its possible if the PSU is exhausting the mobo case your lowering its capacity to a point its having issues with the draw on it. That would of course also coincide with the maximum heat output from the processors

if it wont replicate the issue with a lower temperature, you have your solution, either increase the volume of air to time, or employing ducts lower the temperature differential to the PSU (its own unheated air source)

if you can still replicate the issue, then it could be power quality from the wall socket
when it is at its maximum draw during gaming it might be having issues dealing with fluctuating VAC, whereas when its not so stressed out its dealing with it
 
Good suggestion Ice Czar. The only problem is that I am running with the case gutted out with all sides off including the front bezel.

So far having connected GPU2 to a different rail with the provided PCIe splitter from the Vid Card manufacturer seems to not have issues.

This sucks though, why buy an SLI psu if you cant even use the native PCIe rails.
 
could be a bad connection \ crimp on the connector
could be poor shielding on some component and inductive noise on the power rail
which likely can be cured with rerouting

a few things that come to mind

try to check if the connector gets warm
that is indicative of too much resistance \ a bad connector\crimp

Ok I will check that out. So you are basically saying that the PSU is within spec for what I am trying to use it for and should not be doing this if it was working correctly?

The reason I ask is that it is brand new, and I have no problem sending it back for a replacement. The one thing I do not want to do is get a replacement and have the same problem.
 
that config is well within the specs it should be able to handle
and you have a very specific set of circumstances required to get an issue
trying to eliminate other variables before assigning blame is always the 1st course of action
especially when you might just end up at the same place with a whole new set of components :p ;)

PSUs do get damaged in shipping, there can be quality control issues, there can even be drifts in thier specs because of the selection of different internal components to meet a higher demand or other reason without retesting


but when in the forest its best to look at the trees first :p
 
It seems as though the issue has to lie in the connector or the rail on the PCIe output of the PSU directly. The system has been fine with no issues for the past couple of hours with me moving one of the cards to a different rail.

I also sent an e-mail to Silverstone asking them if they have tested this PSU with 512 cards. Going to wait till tomorrow to get a response on possible issues, otherwise this PSU is going back where it came from.
 
OK just an update. Spoke with Silverstone rep over in California today as well as BFG Tech. According to the rep the PSU "meets SLI standards"...Hmm ok then thanks for that info.

But he has no idea on if or how they have tested this thing for performance with 7800GTX 512s.

So I am sending it back to Newegg for a refund and ordering another brand of PSU.

ICE: Do you have any reccomendations for this system spec?

Opteron175
DFI NF4 Expert
2x 512 BFG 7800GTX
2GB Ram
2 Optical Drives
2 Raptors
Watercooling with about 3 120mm fans and several 80mm Fans?


I was thinking the OCZ 600W or something of the sort?
 
there are alot of good supplies and manufacturers out there
but if your considering the OCZ 600W you might as well get the PCP&C 510 SLi

its easily worth the little bit more
(and don't let the total wattage figure fool you, thats its rating at 50C)

I can unequivically say my 510 is the best supply Ive ever owned

I considered the one. The only problem is that the DFI has the 8PIN instead of 4PIN power connector, which I believe the PCP&C 510SLI does not have.

I just found this thread on the OCZ site that has me worried that I will never find a PSU that works with my system.

just order it as EPS12V compatible

I actually have the 510 AG which is a 24 pin + 8 aux w\ 6 pin AGP pro connector
(not that Ive ever used it :p )
has run up to Dual Opteron 244's, K8W, 4GB PC2700, PNY FX3000, optical, FDD, 9 x HDDs, RAID5 SX6000,
without so much as a flicker to the voltage, rock solid

just tell em you want a 510 EPS12V SLi, that will get you 24 + 8 + (6 + 6 SLi PCI-E Video)

it is still a single +12V rail supply (difference between compatible and compliant)
but its load regulated to 1% and makes multiple rails moot
in addition it has the lowest AC Ripple out there (0.5% p-p)
and a really wide VAC range (90>264)
and a .99 power factor (PFC),
its peak rating is 650W @ 50C
also has a very robust cooling solution, the one point many bring up, fan noise

nothing you can't address with a little forethought and modding however

Tell us how the noise is..and hope it works out for you ;)

Well I am not "too" concerned about the noise. If I did think it was too loud, what options do I have for this unit to replace the fan inside it?
