Sorry for not posting in Power Supply's but I need a very quick answer on this one so I know if I should cancel an order I've already placed before it's too late! (Mods please don't relocate me!! Thx...)
Getting straight to the point:
Should I cancel my order for a CM RS-850-EMBA REAL POWER PRO for $129.00 + Shipping ($142.52 total) and buy the Corsair 620HX for $119.00 shipped?
(Because a modular PS would be sweet AND after all, it's a Corsair).
Background Info for those interested
The Rig:
ABIT IP35 Pro
Q6600
ZALMAN CNPS9700 (HSF)
4GB XMS2 PC6400 (Corsair)
Nvidia GeForce 7900GS
3x WD1600YS Caviar 7200RPM/160GB/Sata 3.0
Lite-On CD/DVD-RW
On Board Sound
Antec 900 (4x 120mm Fans / 1x 200mm Fan)
Cliffs:
1. Built a new rig and though I would at least attempt to get away with an el-cheapo PS that came w/ a different case order last year.
2. PS was rated at 560w (Single 12v rail @20A)
3. PS smoked within 10 seconds of initial power on (In retrospect, I'm not all that surprised/hope I didn't damage anything else!! :shocked
4. Ordered CM RS-850-EMBA REAL POWER PRO from CVS last night under the impression that I would get it for about $70.00 but did not pay attention to detail and realized this morning that the $60.00 rebate expired on Dec 31 - Final selling price: $129.99 + S&H ($142.52 total) but I'm OK with it, the CM 850/1000-EMBA series are getting very good reviews.
5. Checked Hot Deals this morning and found Corsair 620HX for $119.00 shipped @ Buy.com Keep the CM order or dump it for the Corsair??
Info pertaining to cause of failure: (copied from below)
I was pretty careful durring the build taking my time to make sure all connections were properly seated and cables were properly dressed.
The only grey area I has was connecting the power/reset/HDD-Led headers:
The book that came with the case did not indicate which color wire going to the switches was positive although the header on the mobo did. I took my best guess that the three white wires were all positive and the black (for power)/navy (for reset)/and plum (for HDD-Led) were the negatives.
Although I don't think this matters because you can effectively emulate the power/reset switches by momentarily shorting the respective header with a screwdriver and if the LED was backwards it just wouldn't light up.
All other connections were correct. The only other thing that could have possibly caused a short would be some of the Artic Silver somehow getting down into the CPU socket or one of the fans.
Here is the actual behaviour I experienced:
Initial power up:
- Powered on PSU, MOBO diagnostic read 01.
- Powered up computer
- Everything fired up, Fans, leds, etc. and died after about 8 seconds.
- The POST code from the motherboard froze at 8.2. (as indicated by the IP35 Pro's LED diagnostic) which is defined as "Enable ATX Power".
- Hard Powerd down PSU and cleared CMOS
- 2nd attempt at power up netted the same result only sooner and the 200mm case fan barely started to spin up.
- Did another hard power down
- Disconnected all case fans except 1 and attempted a 3rd powerup
- Powered on PSU and MOBO read Diagnostic code 01 again
- Powered up computer
- Led's came on but the single case fan and CPU fan would not even start
- Got POST code 8.2. again after less than 2 seconds and smelled charred components.
- Did a sniff test and visual inspection of the mobo and components - seems OK
- Sniff test of PSU reaked
- Removed and disassymbled PSU and did visual inspection / nothing remarkable - but it stinks to high heaven.
- I'm hoping this is just a PSU problem and not something else
