5 out of 5 eggsAlmost 2 years old now still going strong...

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: >Well made
>Quiet
>Modular
>Sleeved cabling
>2x 6+2 pin PCIe power connectors
>Powerful
>Efficient

Cons: >A little long, blocks a case fan mount on the bottom of my case
>The SATA and 4-pin Molex connectors are too close together. I only have 3 drives, a HDD, SSD and ODD but need to use 2 SATA cables off the PSU because the 3rd connector on one of the cables doesn't reach my ODD.
>Price has gone up, way up, since 2012.

Other Thoughts: In October 2014, I would have had this PSU for 2 years. I started off with an i7 3770k and a single GTX 660. I then upgraded to 2x 660s in SLI and the 550 watt PSU was enough to run them without any issues. Recently, I replaced them with a single HD 7950 boost and it too runs that GPU very well. Higher end cards like the 7950/7970 and GTX 670/680 and above need 2x 6+2 pin connectors so you can only really use one high end GPU with this PSU. You would probably need more than 550 watts and a 45 amp +12v rail anyway so that isn't much of a con. Like I said, I bought this PSU nearly 2 years ago and the price has nearly doubled. I am looking at my invoice from 2012 and I paid $59.99 for it and I'm pretty sure there was a rebate as well. Now, they want $107. If it was the same price now, I wouldn't even consider it. I would definitely go for something like an 80+ gold Seasonic if I was going to spend that much. Like the SSR-550RM which is only $90 at the moment.

3 out of 5 eggs9 months.

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: Modular, looks nice, quiet.

Cons: Ran 9 months then failed. Only hooked to a low power Backup file server MB plus 6 drives. Took one 3TB drive down with it on failure. Was hooked to APC Smart-UPS rack so line power surge was not an issue.

Other Thoughts: Stuff happpens with all power supplies. Now we see what customer service is like. Prior experiences with this company have been good.

5 out of 5 eggsgreat customer service

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: nice modular PSU; sleeved cables. Great customer service: after a year and expanding my HDs in my build, I ran out of SATA power cables and couldn't make some of the empty SATA power reach my HD in my case. So I wrote to OCZ support on their web site and they are sending me a free SATA power cable. Otherwise I would've had to use a SATA Y splitter or a molex to SATA convertion. Haven't gotten the cable yet but I'm loving their service. Way to stand by your product. BTW: the 550 only has 2 SATA cables each supporting 3 SATA drives.

Cons: with my case (ANTEC P280) and bottom power mount, I needed a Linkworld 33cm ATX power supply 24 pin to 24 pin extension/adapter Cable Model 24-24 to reach the MOBO and still have great cable management. But this is case specific. The Antec P280 is a nice case; elegant and large.

5 out of 5 eggsExcellent PSU

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: 550W at a good price, low noise, and the modular cabling is a huge plus. I live in a 2-bedroom apartment that is mildly furnished, and it keeps my electric bills very low despite constant use.

Cons: Could've used more SATA power cables and less IDE cables.

Other Thoughts: The black and yellow scheme is awesome

5 out of 5 eggsOCZ ZT 550W mudular 80 plus Power supply.

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: Neweggs service, price and delivery. Supplies ample wattage, runs cool, modular, you use only the cables needed. Cables long enough to reach. I did use a extention on the 8 pin motherboard cable, in a bottom mount case. Makes a nice, neat, case inside.

Cons: Not really but, the flat cables take a little getting used to. These would be the sata and 4 pin molex.

Other Thoughts: I own 2 other OCZ power supplies. The same of this one in the "ZS" flavor and a Stealth X Stream 2, 500W. All have performed well. Not sure whats going on with the rebate deal, but I always get mine.

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: - Silent
- Fully modular
- Plenty of cables

Cons: - Some of the cabling is strange. They should have included single connectors rather than just cables of 3.

5 out of 5 eggsExcellent Modular PSU

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: The fan is as silent as any I've seen, and it was for an amazing price. Puts out more than enough for my rig.

Cons: None really, though the modular connections consume space near my fan vent.

Other Thoughts: The black and yellow is sexy.

5 out of 5 eggsGood quality, value

This review is from: FirePower ZT Series 550W 80Plus Brone Fully-Modular High Performance Power Supply ZT550W

Pros: Got $30 from a newegg sale and then $20 off with a mail in rebate. Original price $89, got it for $39. Could not find a modular 80 plus 500 + watt PSU anywhere else for this price. Comes with molex and SATA connectors. Very quiet fan, almost silent. 80 plus certified. Received rebate gift card a month later.

Cons: None

Other Thoughts: Best value PSU anywhere.
