After bringing industrial power supply technology to the desktop market, SilverStone is again setting the benchmark for consumer-level power supplies. The ST75ZF can produce 750W continuously even up to 50°C, all at as size easy to integrate into most systems. With an incredible 60A combined (over 700W) for the +12V rail alone, the ST75ZF is capable of powering any top of the line systems available today and beyond, especially with an MTBF of over 100,000 hours.

With one Main connector (20 + 4 pin), one 12V (P4), one 12V (8pin), one Floppy, one AUX power, four peripheral, four SATA, and two PCI-E connectors, you have more than enough for all your components. It sports four next generation +12V rails which allow support for the most high-end PC systems.

Coupled with higher than 80% efficiency and a top quality cooling fan, the ST75ZF is also quieter and more user friendly than its predecessor while providing more power. With major favorable reviews from the PC publications and site, this is obviously a major development in PSUs, and a real winner for your system!

4 out of 5 eggsGood psu

Pros: Dealt with all my overclocking needs and never hiccuped. Survivied through many power flickers and accidental un-plugs. Quiet, strong, came in a pretty box.

Cons: After 4 1/2 years of use it finally gave out. Accidently un-plugged it when the PC was "asleep". Red LED stays red, everywhere I read says solid red=dead. I figure one of the capacitors popped.

Other Thoughts: n/a

5 out of 5 eggsStill Strong!

Pros: It's been more than four years since I bought this power supply. I've never had any issue with it. Power is consistant throughout its lifecycle.

Cons: None

Other Thoughts: Just wanted to pass on to anyone who may be aquiring an old PC with this power supply in it. Will run todays equipment just fine!

5 out of 5 eggsPowerful

Pros: Plenty of power to everything, the many PCI-E 6 Pins are great for my intended SLId 9800 GTXs, Stays cool for just a little fan, no issues with power, Cheap ($99 is great for 750W)

Cons: None

Other Thoughts: Fits fine in my ATX Mid tower. The cords are a little cramped but, it fits fine with my massive heat sink and Graphics card.

5 out of 5 eggsWhat the pros use

Pros: This power supply is just about the best I have seen. It has connectors for anything you can think of and rock solid power. SLI ready and more than enough for a good system build. Nice shielded cables.

Cons: None

Other Thoughts: Cables are long, make sure you have room in your case to hide them.

5 out of 5 eggsRaw Power

Pros: This thing has power and lots of it for anything. With 4 12v rails and the 750 watts being continuous, it will probably handle just about anything you throw at it. Smooth and quiet too, the top of my case hasn't gotten warm yet!!!

Cons: None

5 out of 5 eggsdual eatx tyan mb

Pros: Running 2915 mb with two opterons, a lot of ram huge video card, sata hard drives, dvd, fans, etc. everything but crossfired video and is as stable as anything I've ever built running every graphic intense game we could throw at it.

Cons: main mb 24 pin plug had to be reseated, it wiggled loose even though clip had hooked while installing, wouldn't shut down when windows told it to, just reseated the connection, mb ok, thank goodness, everything ok hasn't came loose again, probably when installing the video card I bumped it.

Other Thoughts: we paid 149 and it was worth it, at 99 it's a steal, big psu but after a month of constant use gaming and sitting still quiet, and stable.

5 out of 5 eggsGood Investment

Pros: Fabulous Price.
Extremely Quite.
Long Cables.
Lots of Connections.
It's Quad-SLI! XD

Cons: Absolutely Nothing.

Other Thoughts: First and foremost, if you can get this one for $99 dollars instead of $150, then by all means get it! It is well worth it and seriously I don't understand why it's been sold so cheap. It's definably an outstanding purchase, specially if you need long cables for those big cases. I own an Antec 900 modded for behind-the-tray modding and all cables were long enough, except the 8 pin CPU power cable. No biggy though, extension for that cable was only $5.

1 out of 5 eggsConsistently Failed Out of the Box

Pros: Very nicely packaged. Has an easy to carry handle attached to the box, the cords were very organized and bundled together and appeared to very high quality.

Cons: This PSU has been the bane of my life for the last three days. My computer would randomly shutoff after being on for only a few minutes - even while idly sitting in the BIOS.

I reseated the CPU, checked all cabling, swapped out parts to rule out other defection - but unfortunately didn't have another compatible PSU around. Went out on a limb and purchased a Thermaltake Toughpower 850W PSU at a local computer store here and memtest86 has been going strong now for over 30 minutes.

I may have simply had a faulty unit, but my personal experience has forced me to rate this PSU with 1-egg.

Other Thoughts: The presentation is nice, but I'd rather have the functionality be the strongest suit when it comes to my internal parts.
