The ST85F from Silverstone deliver 850W of power to your system so you have plenty of juice for gaming, file-serving or both. The dual +12V rails provide a balanced output. An Active PFC and >80% efficiency ensure minimal power waste which keeps the PSU cool.
The power connectors are fully modular. This lets you use only the connections you need. There is a handy carry bag for the extra cables, so they’ll still be around when you upgrade. The cables are all sheathed to de-clutter the inside of the case, enhancing airflow.
It is CrossFire X Certified with 4x6-pin and 2x8-pin PCIe connectors. There are also 6 SATA connectors for all of your high speed drives. The cables are partially mesh sleeved to increase air flow and to make management easier.

Pros: great power....gigabyte M59SLI-S5 mobo, amd 5200+ 2.6Ghz clocked to 2.85Ghz @ 1.4V, 8800 GTS not clocked yet and kept but played with ntune and didnot get unstable and crash until 3750Mhz ...that was a 50% OC as it started at 2500 Mhz. 4G corsair xms 6400C4 set factory OC recommend 2.1V vs 1.8 JEDEC default. Fans = 3-120mm, 2-90mm, thermaltake TMG A1 cpu cooler, 1 Tt memory cooler, 2 X 250G raid 0, DVD, FDD. all running VERY stable. as for those getting power error msg with the 8800GTX see if your mobo has a 4 pin molex connector tagged for PCIe 12V, mine does and it would probably solve your problem, that what it's there for.
Cons: none...ya know some people really should check things out ..in reply to NOT THRILLED...case in point from your test...ALL of those 12 volt reading are WELL WITHIN +12V range..12 volt DOES NOT mean that it will supply 12 volts at all times...check manufac spec MOST ALL specs for +12v is 12V + or - up to 5% in the case of this particular PS the spec is 12V +5/-4 which means the PS will supply power on the 12 volt rail within -4% to +5% of 12V which equals 11.52 - 12.60 volts and that is the operating range of the +12V rail so your disappointment with 11.71V is really not valid,
Overall Review: 11.84V on the 4 pin at IDLE is actually pretty much EXACTLY where it should be, try testing at FULL LOAD and i'll bet you see that 11.84 jump to something like 12.25 (point is, the item and PS will only use/supply what is NEEDED, if it doesn't need 12+ volts to idle then it won't take them) another thing to consider here is if your that concerned with it dropping to 11.71 THEN STAY AWAY FROM MODULAR CABLING, modular cabling creates 1 more connection in the power scheme which INCREASES resistence and therfore will leave wide open the possibility of a +12V rail dropping to its low in range as well as make it harder to deliver it's max range voltage, ANY modular cabling PS will have the same problem. then again if PS did infact supply 12 volts at all times (impossible cuz power fluxuates regardless!!) people would groan cuz the power bill went up a little, so look at it this way over the course of a year that 11.84 vs 12v will save a few bucks on your power bill.
