Summary: powers my rig that has a Gigabyte P35-DSL MOBO, E6600 Core2duo (overclocked to 3Ghz, 4GB 800Mhz OCZ reaper RAM (overclocked to 1000Mhz), Nvidia GTX460 enthusiast edition (GPU overclocked 820Mhz Memory to 1002Mhz), 1 Sata, 1 Pata , and one dvd burner, case has 4 120mm fans.
Pros: I bought this thing in summer 07 and it has been running great since, it has been through two cases and two MOBOs and still going strong. has all the connections I need and then some.
Cons: This ATX12V power supply package does not come with extra extension cables, whatsoever. My motherboard (GIGABYTE GA-MA790X-UD4P), which is an ATX motherboard but 2 of the cables were to short. I had to buy 12V 2x4 pin and ATX extension cables. Pretty frustrating, I must say.
Summary: Never even turned it on. Opened box, saw it was missing fan switch (the whole reason I bought it!) and returned it immediately. I am a frequent buyer on NewEgg and I am very happy with their customer service!
Pros: It came in a box. Cheap.
Cons: Features a three speed fan switch, but some how CoolMax QA missed the fact that this unit had NO FAN switch! I guess you get what you pay for. I RMA'd it and going with another power supply from NewEgg.
Summary: Bought this PSU March 07. Recently (Feb09) wires started shorting out and sometimes caused my compy to turn off randomly. I do play with my configuration a lot so the wires may have worn out after excessive use. Had to not use certain wires just for the BIOS to post.
Pros: Did its job. Lasted until now. Plenty of Connectors. Stays cool.
Summary: C2Q Q9400 @ stock, 6GB DDR2-800 RAM, WD 640GB 7.2 SATA, DVD-Multi Burner SATA, Foxconna G33-S MoBo, HD 4870. I used two different power calculators before buying this, my system only uses about 358w loaded, and this supposedly meets the minimum reqs. of the video card for a fully loaded system.
Pros: Dual PCIe connectors, 32A on the 12v rails (good for the price).
Cons: Did not supply sufficient power for my system (See below), and that resulted in constant crashes and slow downs.
