0PSU LogoThe search for a storage server PSU

Published by & filed under Misc Hardware. Last updated .

I recently pos­ted abi­out my search for a new stor­age serv­er case. My next search involves find­ing a suit­able PSU! It seems in recent years it has got much harder to find the type of hard­ware I like to use, prob­ably because the fash­ion has been to go smal­ler and sleeker which is gen­er­ally more pos­sible in this era of improved per­form­ance-per-watt devices. How­ever, if you have space and you want sys­tems to be cool, quiet, and effi­cient then large is still the way to go.

0PSU LogoEfficient PSU Upgrades: HuntKey Jumper update

Published by & filed under Misc Hardware. Last updated .

I spot­ted a much cheap­er 80+ gold PSU in the ebuy­er xmas sales, and decided to look up some reviews. I found a review on anandtech which I must have some­how missed in the past. In light of this dis­cov­ery, I’ve updated my pre­vi­ous art­icles about PSU effi­ciency to include the HuntKey Jump­er 300G (aka R90).  The price of this PSU changes the con­clu­sions of 2 of the 4 scen­ari­os I’ve pre­vi­ously detailed, and I have in fact ordered one at the dis­count price of £20, for use in my cur­rent serv­er!  After tak­ing into account that my cur­rent serv­er PSU (an Ener­max Nois­e­Taker 475 from 2004) is approx­im­ately 80% effi­cient rather than the 70% worst case I use in the art­icles, I’m hop­ing to net sav­ings of around £20 per year.

0PSU LogoLow power PC — new or old PSU

Published by & filed under Misc Hardware. Last updated .

I have a serv­er that oper­ates 24.7. It occurred to me that I may be able to save some money on elec­tri­city bills if I could reduce its power con­sump­tion. It already has a low power AMD Sem­pron LE-1100 CPU so the power draw of the sys­tem should be quite low, but the PSU is quite old and not espe­cially effi­cient. This got me think­ing about Power sup­plies designed for low power sys­tems. There are plenty of 80+ cer­ti­fied PSU’s out there with 500+ watt rat­ings, but are these actu­ally worth the invest­ment for a low power system?
