Technical reviews clearly indicate that the quality of OCZ power supplies vary. The quality of OCZ power supplies is inconsistant. Some are good. Some are adequate. Some are not so good.
Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts and Antec TruePower New models which are a major improvement over Antec’s older psu’s like the Basiq models.
Take a look and the Lian Li / Lancool Dragon Lord cases. They come in a variety of configurations and prices. Technical reviews are very favorable. Ventilation, airflow, and cooling are excellent.
OCZ is not a PSU manufacturer. Therefore, the quality of each PSU depends on the model.
For example, the OCZ StealthXStream 500 W, and the 600W model, have been manufactured by FSP, and their quality is a worse than the OCZ StealthXStream 400 W, which has been made by CWT. This OCZ StealthXStream 400W is one of the best entry-level power supply in the market (high efficiency of up to 85%, voltages very close to their nominal values (below 3% margin, while ATX spec allows up to 5%) and amazingly low noise and ripple levels). However, I could not say the same for the other two models.
I have had an OCZ 700 Watt Power supply since March of 2006 and it has held up fine over these past 4 years. Still running good. Zero problems. It looks nice and all of the cables are sleeved.
When I built my PC in 2006 I had 4 rebates coming back to me on the components I purchased. I mailed all 4 out on the same day.
OCZ was the first one to send me a rebate check. (Thank you OCZ)
MSI was 2nd a few days later (Their customer service is excellent BTW)
And dreadfully last was Sapphire which was PATHETIC!. They said they would deliver my check in 12-14 weeks and I had to contact them back after week 15. They claimed it got lost in the mail which is a bunch of BULL. Back in the 70s and 80s that may had been a half way legitimate excuse when everything was done manually but now with all of the high tech scanners and tracking that the US Postal Service uses I don't see how anything could get lost. I eventually got my money from Sapphire but I had to keep on them and set reminders up in my calendar.
most of them use the same company to process rebate checks
I mailed rebates using the exact same form, same rebate mailing address, for Gigabyte and Asus video cards. Gigabyte emailed me back saying the UPC code I mailed them was not actually a UPC code....even though it was, there was no other one anywhere on the box, and the Asus one (which looked identical) was perfectly fine...I would not be shocked if those rebate places are employed by drunk monkeys...
