2 out of 5 eggsDidn't last

Pros: Worked without problem during the warranty period

Cons: Died in less than 2 years. Disappointing. I'll be switching to another brand with a longer warranty (EVGA offers 3 years).

5 out of 5 eggsGreat PSU

Pros: Has been working great and as intended. The installation was easy and quick. It has lasted for over a year and I haven't had any problems with this PSU at all.

Cons: None at this moment.

Other Thoughts: Plan to upgrade my GPU to a Super clocked GTX 760 this year and that has a 500 Watt minimum and 30 Amps on the +12 v rail. I' ll update whether it works OK or not.

5 out of 5 eggsDecent PSU for Medium or Low End Gaming PC

Pros: Good enough power supply with enough wattage for almost any non overclocked single GPU gaming rig (not counting GTX Titan or R9 290X)

Cons: Poor quality capacitors so I have doubts as to its longevity. But the client didn't care they just wanted something cheap. And it's only 80Plus certified, not even 80Plus Bronze or Silver.

Other Thoughts: Oh well, at least I trust SIlverstone to make decent choices it's way better than most budget power supplies even with the horrible capacitor choices.

4 out of 5 eggs

Pros: reliable never had any issues with the wiring other than just trying to find the best way to hide it in my case nice and quit, has plenty of power for my rig.

Cons: I would like to see a sleeve over at least the first 6 inches or so and not just over the wires for the 24pin. I also would like to see the 4 pin extended more, on my case it barely reaches even though I have it going straight across the front of my graphics card and all. Even if my case had an easy access hole for that 4 pin I still dont think it would reach and would need an extension.

Other Thoughts: Just keep in mind what you want the end result to be and make sure this will fit how you would like it to. I can see in my case and I rather have it look nicer but hey its a psu.

2 out of 5 eggsWorked perfectly until it died

Pros: Plenty of power cords for lots of devices
Worked great for a few years

Cons: Died after about 3.5 years of moderate usage. Should have lasted a few years longer.

3 out of 5 eggsNice power supply until it broke

Pros: All seemed good , easy to install and looked fine.

Cons: All seemed good until the fan started screaming a week ago and now it has completely failed. Installed it 1/4/13 and died 4/4/2013. I believe these should last longer don't you.
