Never had one this good

Jarod M., Newegg
27 July 2015
  • Summary: Bought it during Zalman's hayday, cant vouch for any of their products after that. but you can't go wrong with this PSU
  • Pros: I purchased this PSU in spring of 2008. Sense then it has been in every new gaming computer build ive done, as it's one of just a couple of components that hasn't needed upgrading. I've never had to use any of the additional cables. It has managed to run mobo,cpu,H50 water cooler, 2dvd drives 3hd...
  • Cons: None, thing just keeps rocking away. never had any problems out of it.

Squeals like a stuck pig

craig s., Newegg
11 July 2014
  • Summary: Do yourself a favor, read up on Zalman warranty issues, or the lack of. I wont be dealing with them again.
  • Pros: lots of power, fan noise is low but that's not good enough for general usage
  • Cons: SQUEALS from electronic coil noise!! It's quite a magnetic disturbance, so much so it made the unit USELESS to use in a recording studio as EVERYTHING within 5 feet got hash from the coils noise impulses. Amps, AD converters, time clock generators, my Fractal Audio Axe FX, any powered speaker/stu...

Would not purchase again

Shane K., Newegg
9 December 2012
  • Summary: I bought this psu to run a dual video card rig that has a dvd burner, and four hard drives. It worked well for a year and now it reboots my machine randomly. It just didn't hold up. Looking for another power supply.
  • Pros: Great cable selection and modular.
  • Cons: Didn't last.

  • Pros: Picked this up 9/30/2008. Been running cool and quiet ever since. One of the most reliable pieces of hardware ever owned, no problems out of it.
  • Cons: They dont make them any more. Power off switch is on the inside of the case.

Not so reliable.

ChulMin S., Newegg
4 July 2011
  • Pros: Worked great quietly until it broke down.
  • Cons: UNRELIABLE!! I purchased this power supply on 12/29/2009. Since then, I used it mostly on 24/7 schedule which shouldn't be the cause of problem in such a short term. About a week ago, my computer started to act abnormally, such as shutting down during minimum load (i.e. web surfing). This continu...

Simply the Best

John S., Newegg
15 April 2011
  • Summary: The best PSU I have ever owned. It sits 1" from a video card in SLI and the thermocouple I have sitting on it never registers a temperature increase of more than 5dC when gaming.
  • Pros: 1) Runs an overclocked i7-2600K and two overclocked GTX580s in SLI without even flinching. 2) Super quiet (the stock CPU fan is louder) 3) Case never heats more than 5C, even at full load 4) All the connectors you could ever want (and they are nicely sleeved) 5) Comes with a 14 gauge power cable,...
  • Cons: 1) Its pricey

Simply the best

Anonymous, Newegg
30 March 2011
  • Pros: The ONLY power supply I have used since they came out. The second you open the box and see this PS, you can tell the quality. The absolute best for any overclocked rig!
  • Cons: Some of the cords are a bit short for motherboard connections if you want to really organize and hide the wires, without an extender.

Great PSU so far

Robert S., Newegg
28 February 2011
  • Summary: Lian Li PC-V2120X full tower case ASUS Crosshair IV Formula AMD Phenom II X6 1100T Thermalright Archon CPU cooler ASUS HD6950 (another second one still to come) 16 gig G.Skill Ripjaw DDR3 1600 Zalman zm1000-hp Plextor 12x blu-ray writer 2x Western Digital Cavair for boot (raid 1) 3X Western Digital...
  • Pros: runs quite and has plenty of power to drive my system. the cables are of high quality and look good. modular cables help cut down on clutter.
  • Cons: some small gripes but overall its a excellent psu, first off the most frustrating for me is that the power cables are not long enough for my tall server case, the 8 pin eatx cable would not reach at all and the 24 pin power cable was very tight. i ended up buying some extensions for both, i think...

No complaints here

Anonymous, Newegg
9 January 2011
  • Summary: I do have an oversized chasis... so it may be difficult on people with "just right" chasis.
  • Pros: Been using it for a year, no problems whatsoever
  • Cons: I guess the only complaint was it is not modular... I guess that would be it
