5 out of 5 eggsHad this for 5 years now...

This review is from: Rosewill LIGHTNING-800 - 800-Watt Modular, Active PFC Power Supply - Continuous @ 122 Deg. F (50C), 80 PLUS Gold, ATX 12V v2.31 & EPS 12V v2.92, Intel Haswell, SLI & CrossFire Ready

Pros: Bought one of these back in 2010, still using it today.
No problem running my setup:
i7 870 2.93Ghz @ 4.2Ghz
2x 560ti gtx (SLI)
16 Gb RAM
3 hard drives
X-fi titanium

Cons: Not really a con (pro)

Had a few instances where it would immediately shutdown when starting the system, split second on/off cycle. Every case was caused by an electrical problem within the system (motherboard needed to be replaced / fan wire had been cut by pci card and was exposed). Frustrating to deal with, but the protections built in to this PSU have saved me a few times.

Other Thoughts: A lot of the low reviews mention that it was DOA / failed within months, saying it turns off as soon as it's starts. My personal experience is that the PSU is doing its job protecting the system.

5 out of 5 eggsEven without the lights this power supply is the best!

This review is from: Rosewill LIGHTNING-800 - 800-Watt Modular, Active PFC Power Supply - Continuous @ 122 Deg. F (50C), 80 PLUS Gold, ATX 12V v2.31 & EPS 12V v2.92, Intel Haswell, SLI & CrossFire Ready

Pros: Plenty of cables
Lights up

Cons: Unfortunately, this power supply can not perform magic tricks for you

Other Thoughts: I actually didn't get this power supply for the lights, I got it for its efficiency and safety. It comes with PLENTY of cables for regular computer builds, and has a good manual. I would suggest getting an extra surge protector (power strip) to plug the PSU into that way you eliminate even more risk. So far the PSU hasn't had any problems, I don't expect it will any time soon.

5 out of 5 eggsThe Best PSU. PERIOD.

This review is from: Rosewill LIGHTNING-800 - 800-Watt Modular, Active PFC Power Supply - Continuous @ 122 Deg. F (50C), 80 PLUS Gold, ATX 12V v2.31 & EPS 12V v2.92, Intel Haswell, SLI & CrossFire Ready

Modular.

LED effect.
Long cords even for a full tower case.
Neatly packaged with cable bag for extra cables & accessories.

Cons: None.

Other Thoughts: If it wasn't for the price, I would keep getting it.

5 out of 5 eggsGood Power Supply

This review is from: Rosewill LIGHTNING-800 - 800-Watt Modular, Active PFC Power Supply - Continuous @ 122 Deg. F (50C), 80 PLUS Gold, ATX 12V v2.31 & EPS 12V v2.92, Intel Haswell, SLI & CrossFire Ready

Pros: I have had no problems thus far with this psu. It has plenty of connections and they were all just long enough to reach my components in a full tower case. You can cover up the extra plugs you don't need and they will not light up when not in use which is actually a good thing. It runs cool and it's 80 plus gold which is nice.

Cons: None

Other Thoughts: Why do people hate on Rosewill? My previous power supply was Rosewill and I never had any issues with it in the 2 years I used it.

5 out of 5 eggsSolid

This review is from: Rosewill LIGHTNING-800 - 800-Watt Modular, Active PFC Power Supply - Continuous @ 122 Deg. F (50C), 80 PLUS Gold, ATX 12V v2.31 & EPS 12V v2.92, Intel Haswell, SLI & CrossFire Ready

Pros: Surprised when i opened the box to find a case organizer filled with the cabling, heavy duty wire gauge. You can hear the relays inside click on when there is initial power. Granted these are little pluses however I believe it is a well built unit. Main harness coming out comes with 2x 6-pin connectors, 2x 4-pin CPU connectors and your motherboard power. Modular connectors are fairly solid and snug fit, however i believe a better metal for the screw ins would be be a little more sufficient. I would definitely buy another one given the chance.

Cons: zip.

Other Thoughts: This would be ideal for future upgrades and believe should be bought as a starter item. More then enough connections for your needs.

3 out of 5 eggs2 years of colors

This review is from: Rosewill LIGHTNING-800 - 800-Watt Modular, Active PFC Power Supply - Continuous @ 122 Deg. F (50C), 80 PLUS Gold, ATX 12V v2.31 & EPS 12V v2.92, Intel Haswell, SLI & CrossFire Ready

Pros: Easy Cables to work with, plenty of connections to work with in a gaming rig.

Colorful lighting (optional)

Quiet.

Cons: Is dying after 2 years of use. Periodically shuts off at random, leaving one rather irritated. I know this is a thing among power supplies, but I've had many other power supplies last me much longer than this without a hitch.

I do not overclock, and my system requires far less than the 800W this PSU provides. All in all, this makes me a sad panda.

Other Thoughts: Overall, this has been a fair power supply. I'm just disappointed with the lifespan considering the price I paid for it at the time. I had never tried Rosewill before, and depending on the Customer service, may or may not continue with them in the future.
