Came with Printrbot Plus

Alex L., Newegg
19 June 2014
  • Summary: This psu came with a Printrbot Plus that i bought about a month ago and has been running it alright. When i set the bed to 100C it would not reach it. It would get to 86C and would not go any higher which was quite a let down since it has to be at 100C to print ABS.
  • Pros: Supplies power. Runs cold. Very light. Hasn't died yet
  • Cons: Fan runs at full speed constantly. I don't think it supplies 400W but that's just a assumption. I don't trust this power supply to last long. It's too light weight feels too cheap to last.

Cheap, but not very quiet

Stephen G., Newegg
19 January 2013
  • Summary: Used this to replace a 120mm fan PSU that failed on a low power HTPC rig. It's been running for fine for 3 days, but it is noticable louder than the unit it replaced.
  • Pros: Light weight. Cheap. Got it cheaper else where than list price here.
  • Cons: It's not very quiet. 24+ db measured with an un-calibrated phone app.

Piece of Junk

Kurt W., Newegg
12 January 2013
  • Summary: It would be great if Newegg would test a few items like this for issues before releasing them to the public. Sure would save a bunch of aggravation.
  • Pros: Newegg came through with a free return shipping label to RMA this thing.
  • Cons: The power supply is still a piece of junk.

P/S Ripoff

Thomas K., Newegg
27 December 2012
  • Summary: I wish Newegg could get someone to test/sample quality of items (at least that they work) before agreeing to sell or ship them but appears all we have is these reviews from those customers who have, in effect, paid to be a unknowing tester.
  • Pros: Newegg finally sent me a paid return label so now if I can get into town this week, back it goes for refund.
  • Cons: As noted in first review, tested the lightweight P/S right out of box and tested "bad".

Beware RIP-OFF

Thomas K., Newegg
27 December 2012
  • Summary: All you get on Egg ph service is will-call back recording. Online RMA give $13+ estimate to return for $19+ refund so of course its a waste of time and a ripoff of customers. Ordered a lot but this first time I have had a BAD experience with Newegg and this may well be my last order.
  • Pros: 2 different Testers show bad (danger) power from get go right out of box.
  • Cons: Test before using. This unit shows dangerously low +12.2v readings and should not be used.

Piece of Junk

Kurt W., Newegg
24 December 2012
  • Summary: Installed the power supply today - got BIOs error message at boot, and PC locked up. Tried restarting PC several times with same result. Then PC died completely, and wouldn't power up at all. Had to put my old (weak) power supply back in to get it to work.
  • Pros: None.
  • Cons: Power Supply died within 20 minutes.

User Review

Robert L., Newegg
21 December 2012
  • Summary: I put this into my system, booted and installed Windows, and not long after it died. I have used many inexpensive power supplies in budget system builds but this one is the worst. Spend an extra $10 and you'll get a much better power supply.
  • Pros: Won't add much weight to your system.
  • Cons: Very light, feels empty. VERY cheap. Died within 30 minutes.

Bryan R., Newegg

  • Pros: Power supply has not been used yet.
  • Cons: Power supply is probably OK but the advertised rebate process cannot be completed. The issue: you need to go to coolmax.com rebates to preregister for a rebate number but then you get Catch 22 - the Model I-400 is not listed as a power supply with a rebate. So...the rebate process cannot be compl...

very noisy

Wei D., Newegg
29 November 2012
  • Summary: I gave it one egg because the computer actually boots with the power.
  • Pros: Dirty cheap.
  • Cons: 1. This power is too noisy to be useful. 2. The CPU power cable is kind of short, and I have trouble reaching the CPU power connector on one of my case/motherboard configuration.
