Honore H., Newegg
23 October 2012
  • Summary: Very good power supply. I was worried it wouldn't be enough power to run my system at 50% as that is the most efficient the PSU gets. The worst it gets is 89% at 20% power (50watts). My 6870 + 2600K get at most 225 watts which is perfect and idles 138Watts.
  • Pros: 80 Plus Platinum! 450Watt design Std. ATX dimensions
  • Cons: None. It would be nice to see a modular version. I have this thing in a Lian Li PC-Q06 test bench case and it is a tight fit. but in my HTPC case it would have been a nightmare routing cables.

silent, solid, and over-cabled

Evan C., Newegg
3 October 2012
  • Summary: I've had great luck (knock wood) with Antec over the years. Had a long look at SeaSonic X series, but couldn't find a decent/well-priced one in the sub-500 watt range.
  • Pros: Near-silent (so much so I'd say 'silent', but the purists get offended), very clean line voltage, solidly built, and absolutely standard ATX dimensions, which means it fits without any problems in most cases - including proprietary cases (like Dell, or HP - I just replaced the meager 300w PSU tha...
  • Cons: Too many cables. For a 450 watt supply, you're not likely to have 5-6 drives, Sli vid cards, or lots of other power sucking things, so why cable the PSU as if you were going to run a full-blown and p*mped out rig? I need 1-2 SATA connector, 24-pin ATX cable, CPU (4- or 6-pin), and generally, that...

Good PSU

Brenton F., Newegg
17 July 2012
  • Summary: I didn't have a need to actually upgrade my PSU, but I am happy I did. Despite running into slight issues getting enough power to all my devices, my idle wattage using a watt meter went from ~130 watts down to ~100 watts.
  • Pros: High efficiency and I do not hear it's fan.
  • Cons: Length of the cords can be an issue when using being the motherboard wiring trays (you would think this wouldn't be an issue in Antec's own P280 case), also I ran into issues with the sata connectors and attaching 4 hard drives and a sata DVD drive. One of the cables out of the PSU had to be cons...

Eric L., Newegg
12 July 2012
  • Summary: I've bought antec supplies say maybe 8-10 in the past and this was the first dud. I doubt I will continue to buy them though.
  • Pros: It is a nice compact power supply with all relevant plugs.
  • Cons: I was building up some new lab equipment so it had to be green, had to be up and running that day. Well after messing with the PSU and a scope; it was clearly dead on arrival. I'm very mad I had to explain delays due to a inferior product w/ QC issues.

Cool and Quiet

Jeremy D., Newegg
8 May 2012
  • Pros: Easy to install (as is the case with most power supplies) and the cables have enough length for my Mid-Tower sized case. It runs really quiet and puts off only luke-warm heat at most.
  • Cons: It's a 450W power supply, so if you're needing more juice for a power-hungry rig, a bigger unit would be wise. Otherwise, it has enough watts to power most low- to mid-end computers

Great deal - DOES have Active PFC

Alexander B., Newegg
19 March 2012
  • Summary: About the PFC - Saw today's 15% off deal and was highly intrigued when I saw this platinum with the 5.5" depth, but was surprised to see the line in the Newegg specs that read "PFC: No" for something rated at platinum efficiency.
  • Pros: I just ordered today and haven't received, so I can't speak to the performance of the PSU. Design-wise, am very happy to be paying a reasonable amount of money for a PSU (1) with the highest available efficiency rating, (2) with this low of a wattage rating (to get a NAS build well within the 20%...
  • Cons: Too bad this doesn't come with a 5-year warranty - not that I regularly exercise warranties or track coverage very closely, but it's just a more-solid indicator I think of the company's confidence in the integrity of their product. 'Fingers crossed'. I am scared that the PCI-e connectors are goin...

Great high quality power saving choice

William W., Newegg
24 February 2012
  • Summary: Very high quality you can see & feel. It is quite heavy but that is good in a PSU. I've always loved Antec for the quality & the same is true here, just wish they were cheaper. (newegg sale helped ease the pain) I'm sure many would see all the cables as a plus but in my case it was WAY overkill.
  • Pros: SUPER POWER SAVER! I compared power usage using kill-a-watt with an older common name 60% efficient 500W & this 450W antec with exact same hardware. (ASRock H67M-ITX, i5 2500, 2x4G & 1 2TB Seagate Green) Old PSU @ Idle=48W, 100%=123W. This Antec @ Idle=29W, 100% 89W. Tell me that won't save some ...
  • Cons: Not modular but I knew that. Would love to have been able to remove cables not needed in my LIAN LI PC-Q08 mini ITX case. It fits by tucking all the extra's where possible but would have been much cleaner install if I could have just unplugged the extras. A bit on expensive side w/o sale/discount...

Impresionante fuente para limitar el consumo

Manuel, amazon.es
7 June 2013
  • Summary: La compré por su certificación 80 Platinum, y no me ha defraudado. La quería para un equipo de bajo consumo pero con capacidades de ampliación futuras, una Gigabyte GA-Q77M-D2H y un 3770s, con un disco green de 3TB 3,5" y otro ssd, más 16 GB de RAM Corsair a 1600 MHz.
