Unreliable 3/13/2008 4:16:51 PM

Pros: Nothing above average. Wattage output is what I needed for my rig, and the PSU had plenty of leads. Damning with faint praise, I guess.

Cons: The unit failed after about 7 months of light to moderate use. Manufacturer support is through web form only, which was broken (did not submit) at the time of this review.

Ok but only get support from email? 12/2/2007 3:05:22 PM

Pros: Great after I had to return my first one to the manufacturer. The email support scared the **** out of me. But had great responce so I will trust them.

Cons: First one went up in smoke and a blaze of fire. But a pro to this con was the PSU here has a great system protection built in and nothing else was destroyed. Not sure what was wrong with first but the caps all blew. Exciting I know LOL

Overall Review: I probally would say a great one for those who need power but its big and bulky. Not one for showin off that sweet gamin rig.

If it only had 4 PCI-e's 9/14/2007 4:12:35 PM

Pros: Runs cool and quiet pushing a D975BX2 MB with quad CPU, an HIS HD 2900XT, 6 HDDs and a DVDRW.

Cons: Only 2 PCI-E connectors, if I go to Crossfire, I’ll have to replace it. Not really a con. I got this PS for an SLI system that never got built. Technology marches on.

Overall Review: It is large, check the MFG’s web site for dimensions and get out your tape measure. I had to pull the MB (my bad for installing it first), remove the flange from the back of the PC, and drop the top mounted USB port module from my Thermaltake tower to get it in. It was a hassle, but everything went back in place after mounting.

Solid PSU! Too big in size. 8/2/2007 9:17:22 PM

Pros: It's a very affordable 850 watts PSU. It has plenty of sleved power cables, although some of them are somewhat short. It has two 80 mm fans--one on the front and one at the back--, which allows for excellent air circulation! It has FOUR 12V rails rated at 18 amps each!!! Most of the priciest units only have 15 amps, even on the dual rails! That's even more important than the wattage itself. It supports ATI Cross Fire video boards (2 cross fire power lines).

Cons: The unit itself is very long! I had the hardest time installing this unit in an Antec case--which calls for the PSU on the bottom--for thermal purposes? It's also very heavy. I doesn't have modular cables, so the unused ones cram the tight space even more.

Overall Review: I have a pretty demanding rig with two ATI Cross Fire video cards, three SATA HDs, 2 DVD drives, 4 GB of RAM (OCZ) and a host of other goodies. I've everthing hooked up to a PW5 PH Deluxe Asus MoBo, with Vista Ultimate OS. If you're looking for a reliable PSU for a serious gaming system, this is a pretty good choice. By the way, I haven't noticed the noise, since I've plenty of fans in the case.

Stable but loud 6/26/2007 6:51:25 AM

Pros: It's stable, and it certainly provides more than enough power to all of my components.

Cons: The fans are irritatingly loud; if noise is a concern, then don't go with this power supply. Also, it would have been nice to see some modular cabling, but I knew it didn't have that when I bought it so I can't really complain.

LOUD FANS 5/24/2007 9:52:46 AM

Pros: Works without any problems, connectors fasten securely

Cons: The LOUD FANS are driving me up the wall, I'm about ready to pull this puppy out and sell it, replace it with a Seasonic.

Overall Review: You would think that a $xxx PSU would be a little quieter.
