5 out of 5 eggsWould buy again luckily don't need to

Pros: Reliable, good price, not too loud

Cons: Nothing of note

Other Thoughts: Have had this running almost 24/7 for more than 5 years. Saw that it is listed as a tier 3 PSU on an "eggxpert" list of various PSU (that's after tiers 1,2a, and 2b). Currently powering i7 920 and gtx 760, going strong.

5 out of 5 eggsSolid and stable

Pros: - Modular
- Efficient
- VERY reliable
- Quiet

Cons: None.

Other Thoughts: This has been running a 24/7 home server since I received it 4 years ago. I have not had a single issue with it. It has been rock solid.

If you don't need a ton of power and want something modular, reliable, efficient and quiet I doubt you will find anything as rock solid as this power supply at this price.

5 out of 5 eggsVery Reliable

Pros: Plonked this in my home server and forgot about it - it's been very solid and reliable, running for a few years now.

Modular cabline is great, I wish all PSUs did this - my desktop is a mess with all the cables that I don't use.

Cons: None

5 out of 5 eggsDurable, Fantastic Value

Pros: 1) Reliable and stable.
2) 80+ Modular
3) Cable length is perfect for wire hiding in Mid Towers.
4) Should be more than sufficient for almost any mid GTX700 card.
5) Look at the price again.

Cons: Nothing.

Other Thoughts: You simply can't go wrong if you are running 1-3 HD's and a recent middle market Nvidia GPU.

Don't worry about the "600w required" on many GPU's,, that's only for low efficiency P/S that most inexpensive cases and PC's come with.

5 out of 5 eggsAntec Stable Reliable 5 years on

Pros: We have had this for so long that we just haven't given it much thought. When you shop for components and you are unfamiliar with a brand or model you may have your fingers crossed for a while but Antec has always been reliable for me. All previous Antec I have purchased still work to date including my first one back in 2002.

This is powering

MSI 785gm e65 motherboard
Phenom2 CPU
MSI GTS250 video card w/1 gig ram
4 gigs of Mushkin 1600 ram
5 hard drives
1 SSD drive
Liteon dvd disk drive
syba usb sound card
4 case cooling fans
120mm cpu fan
usb headphones
2 usb mice

Plenty of molecs and sata power connectors

The cabling is quality

Cons: There is just not any cons that I can think of.

Other Thoughts: When I hooked up a meter to the pc power connector the system idled at 80 watts and during my game play it used 300 watts so there is and has been plenty of overhead and I plan on using this PSU until it is maxed out to specs but then again after 5 years that may not ever happen.

Over the years I have used Antec and I have never had one break or die. I know there is a certain amount of luck involved but these are built by great engineers.

Don't buy a cheap power supply! A cheap power supply is
not worth the headaches that comes with them and the worry of a fire. Cheap PSU's either have no protection circuits or possibly unreliable ones. When you buy cheap you accept that chance.

Even though I personally have never had a DOA Antec that doesn't mean it can't happen nor would it deter me from continuing to be a customer, those things happen and it comes with the territory.

5 out of 5 eggsIt works

Pros: So far, so good. I bought a similar PSU back in 2006 that failed after a year, so let's hope this one lasts longer.

Cons: None.

Other Thoughts: I made this comment on my other parts as well:

Computer parts are freaking cheesy these days. The z97 mobo flexes when you plug things in, the GTX 760 bends downward on one side due to its own weight, the stock Intel cooler is held on my flimsy plastic clips, the case is slightly bowed inward due to a manufacturing defect, and the modular PSU came with bent pins. All of the parts came from reputable manufacturers.

9 years ago, I spent half as much on a budget build and had much higher confidence in the durability of the parts. It seems as though durability has been reduced across the board for new products. With this new build, I’d be afraid to bump the side of the case.

5 out of 5 eggs

Pros: Antec quality with modular power cables.

Cons: None.

Other Thoughts: I have three of these in use and not had a single problem. Works fine in my main rig with a 95 W AMD processor, HD 6850, 3 hard drives, and one optical drive.
