Pros: I'd read so many bad reviews on this board I almost didn't buy it. It went into a new build in an Ultra Tower, Ultra 600w xFinity, x2 4800, 7900 GTO, 4Gig Corsair C4, Mini-Typhoon. Very first try, booted right up, created a smokin RAID 0 on some 10K RPM drives and has been going strong without a hiccup. Temps are in the mid 30's for mobo & low 40's for cpu. Gets my 5 eggs - no question.

Cons: If anything the BIOS is overkill, unless you are a dyed in the wool, major league oc'r.

Overall Review: Would reccomend this board to anyone with the skill to assemble a pc, that's all it took.

Pros: Great Thermaltake reputation together with excellent history of NewEgg service.

Cons: Arrived DOA. Tests on 3 PSU test units showed failure of the 24 pin line. It was the same on all three tests. Really glad I tested it before installing.

Overall Review: I've asked for a replacement and RMA'd the dead one. My board wants a minimum of 600 watts and that's what it's getting now. I'll review the replacment 850 after it's been in service for a while.

Pros: NewEgg service can't be beat. Thermaltake's 5 year warranty on this unit says a lot. My board requires a minimum 600 watts, but the 850 gives it some breathing room. Currently running a dual core AMD, dual Raptors in RAID 0, 1 other SATA WD 150 for backup,eVga 7900GTO, 4 gigs of 800MHZ RAM, TT Mini Typhoon and a slew of fans. I plan on upgrading to a multi-core cpu and multiple gpu's. The TP 850 should handle that with no problem. It's everything as advertised and very quiet.

Cons: As Sluggo said, it won't pass a standard PSU test, even though the unit is fine. Max sustainable 12v load is 62 amps. Both should be clearly stated somewhere.

Overall Review: I reviewed one earlier that I thought was DOA because it failed 3 testers, but this one did the same and it performs great in my system, even better than expected. No second thoughts about this purchase. It's worth every penny. The 3% limit on voltage variation is a very nice plus. And, thanks to the NewEgg webmaster!
