Shhhh. Be vewy vewy quiet. I'm hunting keys

http://hardwareinsights.com/huntkey- ... ly-review/

"Huntkey" does sound like a very old first person shooter game, along the likes of "Herectic", "Doom", "Wolfenstein", etc....

With an exhaust temperature of 37*C, I'm surprised it shut down. I wonder what part of the PSU was overheating. I also spotted a small Rubycon which seems to be around the -12V rail.

Yah, as I stated in the review, nothing seemed to be getting very hot. The transformer was at about the same temperature as the secondary heat sink. I reckon the OTP is too sensitive on this unit.

Ive seen some new huntkeys in Lenovo Desktops they are like half the length of a regular atx supply and are only 180 watts yet lenovo thinks this is enough for an i5? put in any videocard and It will go boom.

Yup. It's quite common for OEMs to only use a PSU which doesn't have enough juice for any significant upgrades.

It also looks like that 470µF 50V unit on the primary side is another one of those annoying thin and tall types.

The only match that I know of is Nichicon HW series (or the elusive Chemi-con KYB) — unless you're daring enough to try a general-purpose part (which may actually work in that position, though their low endurance ratings would not be a good thing with semi-fanless operation), that is. As for me, I'd prefer to use low ESR capacitors even in linear supplies (it's not like they're a huge expense, anyway, especially if it's for something you intend on using for 20 years plus).

EDIT: Nevermind this post, there is indeed a KY (and Nichicon HE) that matches. I hadn't guessed that they existed, but there you go. (Why don't these forums support superscript, subscript, or strikeout?)

RS components have NCC KY in that size (10mm dia), which happens to be a perfect match in terms of electrical specs for the original AiShi cap.

I see Huntkey is still selling overrated units. Labeled as a 500 and only pushing 450. But at'least it is very efficient and safe to use. It's just still sad they use the overload rating. Regardless that is still misleading.

Well, it's not as bad as they have been doing in the past. This unit is perfectly capable of the labelled 500W. The only thing stopping it is the Over Temperature Protection.

On a related note, a certain brand of bad caps had a name that sounds like an awesome character to play as (give or take a space in the middle).
