5 out of 5 eggsGreat for a budget build

Pros: cheap. Best bang for buck. Very suggested. semi modular, And long lasting.

Cons: Cables a bit too short. But can work around this.

Other Thoughts: The build quality of this power supply is a bit cheap, but as long as you don't treat it like garbage it won't be garbage.

1 out of 5 eggsBiggest piece of junk I've ever had for a PSU

Pros: Nothing.

Cons: I bought one of these - and ran a 400W load on it. Came home one day to find it stone cold dead. Packed it up - sent it to Coolmax warranty. That cost me shipping - I'm on the East coast - they're on the West coast. So there's another $35 down the drain. They sent me a new one in the wrapper. I had already replaced the Coolmax with another brand - so I sold it. Shipped it out. That person just told me that this one is dead too. So he doesn't want it - and I'll likely have to eat the cost of shipping it back to me - as well as eat the cost of shipping it to him. This PSU is a darn nightmare. By the time it's all said and done it will end up probably cost me over a couple of hundred for this piece of junk between the shipping costs and initial purchase price - and I still won't have a functioning power supply. I would NEVER buy Coolmax again. Complete waste of money.

5 out of 5 eggsA Really good 1000W Power Supply

Pros: Reliable and stable. Modular. Has all the plugs I need for my Mining Rig. Energy efficient. Nice look.

Cons: Not 100% modular, but who cares.

Other Thoughts: I'm using this on a 990FXA-UD3 motherboard, 45W Sempron CPU Single Core, 4x 7850 Video Cards. It's been very stable. I am pulling 590W on Intensity 15 on SGMiner. I am churning out 1.3Mhz a second. I'm using Xubuntu, not Microsoft OS.

2 out of 5 eggsQuality Control Issues

Pros: Provides correct voltages and comes with plenty of cabling to hook up a dual card setup. High amperage on the 12v rail means you can run the best CPU's available.

Cons: Quality control issues. Fan failed in 3 days, rail overheated and capacitor failure in a week. Voltage dropped off sharply from rated output to next to nothing.

Other Thoughts: This is pretty unacceptable. Newegg has a good policy on returning PSU's but if you can't accept the yourself a Corsair.

5 out of 5 eggsBest for budget build!

Pros: This is a great buy for a budget build! If you are looking for the best bang for you're buck this the one you're looking for. Lasts me about a year know with two GTX 780s in SLI. It is also modular with braided cables, makes my case look nice.

Cons: none come to mind.

Other Thoughts: I don't see why people want the really expensive ones when all that you need is right here. you might want to put a dust shield on the intake just to be safe.

5 out of 5 eggsGreat graphics card

Pros: I have used this power supply for mining litecoins and dogecoins with two Radeon 7770s and a 7850 for the last month and this power supply handles it extremely nicely even with over clocked cards. The modular cables are really nice and allow for great air flow

Cons: Nothing

3 out of 5 eggs

Pros: Cheap
Modular design

Cons: Died after a week

Other Thoughts: Mine died after it'd been running at 940W for a week. While it was running it was cool and quite, the fan never went high and the body was always cold.

I ordered two more to see if they're going to be more reliable, and I write an update to my review asap.

Other than this unlucky death I see no competitors at the price, and I hope it was just a bad item.
