Can you try a different PSU?

I've had 2 members at DFI-Street report Hiper problems today!

What problems Fella? , anything like mine?

No different psu to try

edit : no matter i see em
A review i found...

However, 20 minutes into the 75 per cent load stress test the Type R started to behave rather oddly. What happened could only be descried as a minor disaster and we almost had to cancel the whole test. Although the Type R passed the stress test, it switched itself off a couple of minutes. Far worse though, it had managed to damage the test equipment we where using! Luckily the engineers managed to repair it after a couple of hours, but it was one problem we hadn’t expected to come across

Verdict

The Hiper Type R looks great, but sadly it is troubled by poor wiring and proved unreliable.

These are stats coming from my ASUS Probe software. (edit) This computer was built almost exactly a week ago, and we noticed the PSU numbers fluctuating about 3 days ago.

I'm using this power supply in a completely new computer i built http://www.newegg.com/Product/Produc...82E16817153023

http://www.newegg.com/Product/Produc...ription=22-144 (ok it looks like the HDD i bought last week isn't even for sale anymore on their website, it was a 250 gig western digital caviar hooked up via SATA, i also have the alternate (SATA?) power plug hooked into the HDD instead of the normal power supply.. is this a bad thing?)

(case shouldn't important but just in case there might be something wonky with tihs brand of tower i don't know about http://www.newegg.com/Product/Product.asp?Item=N82E16811144170 )


and this is what ASUS Probe is giving me when i record the history and leave it sitting in windows overnight.

3.3v rail 3.408 to 3.248 most often 3.312 with occasional fluctuations to the high and low points (not too concerned there)

5v rail 5.22 as constant with fluctuations around 5.376 often and have had a couple spikes above 5.5 which sets off my ASUS probe warning

12v rail most often at 11.450 to 11.400 with occasial dips down to 10.5 which have set off ASUS probe alarm.


i've had 3 spontaneous reboots now. One of them seemingly random when i tried to kill a software and twice when i've tried to shut down my computer. My room mate says i should probably ditch the PSU pretty quick but i'm wondering if this is just a sub-par PSU brand/type or if a RMA might fix my problem. Any suggestions?

Ummmm is it me or do these new people not know how to read?
Im pretty sure in the original posting it says something about "you cant use a software program to test the spec's on a PSU" only way to get an acurate reading is to use MM.........

TOLD YOU those cables sucked. That and the fact that it's not a 580W, but a rebadged 550W.

That quote looks like it's from Tom's Hardware.

Figures, sounds like something stupid Tom's would post.

And yes, they need more than 1 18ga wire!

Lol at you guys thinking it was from tom's hardware , then the next guy jumps on the bandwagon

They have been pretty good actually.

This was the second time someone used that quote & I had to find out where it came from.

Thanks again,

Just picked up a Seasonic S12 650W with quad 12v rails. Software shows 11.78v and 4.78v ROCK STEADY at all times. Slapped the DMM on the molex and had 12.11 and 5.0something at idle and load with Prime95. Run 3DMark and still steady. Decided to put the meter on the 4 pin MOBO connector and fluctuated from 12.10 to 12.11 under Prime95.

Think this is gonna be a nice powersupply and another testimony to the DMM. This badboy is replacing a X-Connect (I know, I know!!!) powering a 3700+ @ 2.87, 7800GT @ 500/1200, 2gigs of ram, 2 hard drives, 2 optical drives, 7 120mm fans, 2 cold cathodes, and a Laing D5. Must of got lucky with the X-Connect, rails would drop a little, but still in spec.

Very informative this thread I must say. I used to fix B&W TV's years ago...and I have all that gear....(e.g. voltmeters)...now I am turning my attention to PC's...which are much more simplified.......with only a few circuits unlike that of the TV. I have however a question about PC power supplies. I have an old one..which was on my wardrobe. I got it down...attached a 240v line to it..and switched it on. Nothing happened. I tested the secondary voltages (i.e. -5 +5..-12 +12 etc)..nothing.I figured that perhaps for it to work..the power supply has to be ATTACHED to a motherboard...where it has some switching arrangement for it to be turned on. I asked a few PC techs.....SOME say that it should work...with just the 240v feed....others said no....it has to be attached to a motherboard..together with the CPU and RAM.

I bet that we may be the only ones that have ever used a VTVM!

Yes, ATX PSU's can be jumped like this: http://forums.extremeoverclocking.co...d.php?t=118964

But require minimum loads to run for very long.

Thank you for that info.
The PSU that I have is, I think, pretty old....and I do not think that it is an ATX type.
It has ten connections (wires) in the secondary and they are coloured as follows:
4 are black
3 are red
1 is gray
1 orange
1 white.
There is no colouring as you described.As I said I am reading up and learning on PC's..and the book I am learning from gives the color coding, which it says is UNIFORM in all PSU types as follows:
Orange +3.3.v
Black Ground
Red +5.5v
White Power Good (what exactly does this mean?)
Purple +5vsb
Yellow +12vdc
Brown -12vdc
Green PS on remote (and this??)
Blue -5vdc

I just noticed something that the Sata power cable has a yellow, orange, and red connector it has all 3 rails to test am i correct also how do u test both rails because can't one rail flux without affecting the other? I have a Antec Neo550HE so 2 connectors on one rail and 3 on the other at the power supply so i can test both but some power supplies are not supperated like this. but this is a thought maybe a idea of to add if is useful but the SATA power cable am i right on that being to test 3.3, 5, and 12 volt rails with this alone and make this action alot easier if willing to back probe.
well i just noticed i have 3 12v rails one is deticated to CPU and the others are for everything else? am i correct?
My 12v rail says 11.93 to 12.01 goes back and forth 5v rail does the same 4.93 to 5.01 but the 3.3 is only reading 2.7v could i have probed the wrong orange wire on the ATX connector or what?

quick question..

sintek 600w psu

the 3.3 v line after 5+ hours slowly (under full load) (say playing games) drops to 3.15 etc... event lower en to restart system

if you turn off psu (5min break) its good for 5 + hours...

(wih no load for 5 hours) it only drops to 3.17 for 5 min before going back to 3.34

- im testing if with 3dmark 01 loop for 5 hours..

i jusdt want to know (is it normal) and how to fix (techn)

because (the local suppyler) has gone under.. and i have to send it to the us to be fix (no local warrenty anymore) itl will gost my $100+ aust dollers just to post....

and the refub unit they send back (orig has 5 year warr) they give 30 day warrenty...

sintek 600w sli psu...



maybe it will be cheaper th get a prof tec to repair it localy (paid for)..

or get a new psu..

1` year old 250$ this psu cost me....

There is probablt nothing wrong with the PSU.

Winbond sensors are temp sensetive.

My results of the PSU test on a Cooler Master LGA775 that I bought at CompUSA on sale for $25.00 after rebate.


3.384, 3.368, 3.388, 3.388 to 3.389, 3.385 to 3.386, 3.387 to 3.389

5.15, 5.16, 5.14, 5.14, 5.15 to 5.16

11.88, 11.89, 11.83 to 11.93, 11.92, 11.87 to 11.88, 11.90

This appears to be a satisfactory PSU.
