By the way, talking about Xilence, I also took delivery of one of their case fans that had bad bearings. I'm not very impressed with the quality of that company's products and now avoid them like the plague. (*QuietPC, on the other hand, were very good, initially swapping the units and then giving me a full refund without any hassle. They also sent a courier to collect the duff units). I suspect that my main desktop is a little more power hungry than yours, although not a great deal so, and it's all humming (actually, very little "humming") along beautifully using a Nesteq "Semi-fanless" 450Watt PSU. Nesteq are expensive compared to the generic, Chinese-made units, but the build quality is superb, and the modular cabling is a welcome relief after those multi-tentacled, brightly-coloured looms resembling David Seaman's ponytail on a bad hair day. My unit is also very quiet indeed (in fact inaudible over the case fans and CPU cooler, despite all of these being good quality "quiet" items). The QuietPC technician claimed that Nesteq's units have a significantly more stable and reliable supply than the typical no-brand, £15-£20 jobbies and thus can be used in setups that would normally require higher-rated, cheaper units. I have no way of accurately verifying such claims, but my 450W Nesteq has run my (home-assembled) main desktop with its dual-head NVidia 7600, 2GB RAM, dual-core CPU, single HD and DVD writer, 1 x 120mm and 1 x 92mm case fans, large Zalman CPU cooler, etc. absolutely fine. No mysterious lock ups or shutdowns, or any other apparent electrical anomalies. You do have an extra hard-disk, and my Nvidia card is passively cooled, so I'm not really sure how our machines' respective power requirements compare.

I have a Xilence 420W PSU and I was running a Phenom X4 with 3 hard drives and a DVD writer and a couple of fans and it worked fine. I'd certainly say it's worth paying the extra for a quieter PSU. Other alternative would be something like a Corsair 400W PSU which is 80+ certified which IIRC means when it's on full or high load you will get at least 80% or the rated power. http://www.aria.co.uk/Products/Components/Power+Supplies/200w+to+449w/Corsair+400W+CX+Power+Supply+?productId=34003 Rob -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
[ubuntu-uk] [OT] ATX power supply seems to have lost it's X-factor
Hello :-) The power supply on my desktop machine seems to have stopped functioning as normal. It still works, but when I shut my machine down it no longer stops. The power supply is either on or off. Even after switching it off at the wall, when I turn the wall power on again, all the fans start spinning! Anyway, I think it may be time for a new PSU and am a little uncertain as to the power requirements. It's an older desktop, but for my current usage, and only Ubuntu, resources are not a serious issue so don't want to spend too much money, but might as well go for something a little silent. Here are the specs: AMD Athlon XP 2400+ 1.5GB RAM 3 small case fans (will probably reduce this to one) Nvidia GeForce 6800 GS (requires one power plug) DVD Writer 2x IDE drives I'm swinging towards an Xilence 480W PSU [1] from aria for £26, but not sure if it's (a) worth the extra money for a quieter PSU, and (b) if 480W will be sufficient for stability? Any ideas or suggestions?
