GOOD powersupply for under $40?
Well, I've taken the suggestions (great suggestions!) from a couple previous
threads, and decided I need to get a quality PS. But...I'm having a hard time narrowing one down...especially in my budget. $40 or less. And preferably at least 350 watts as close to TRUE 350 as possible. Any suggestions, especially 2 fan ones? I found this: http://www.newegg.com/app/ViewProduc...alog=58&depa=1 I don't think I've seen Coolmax on anyone's quality manufacturor's lists...but the numbers (amps and total 3+5+12 line watts) seems pretty good. Well, thanks for any feedback! Liam |

But the brand name... ? |

If list retail price is significantly under $80, then
probably missing essential functions. How to determine a quality supply. Up front and first, it provides a long list of numerical specs. Specs that inferior supplies cannot always meet and therefore don't provide. An abbreviated list of specs that any acceptable supply claims to meet: Specification compliance: ATX 2.03 & ATX12V v1.1 Acoustics noise 25.8dBA typical at 70w, 30cm Short circuit protection on all outputs Over voltage protection Over power protection 100% hi-pot test 100% burn in, high temperature cycled on/off PFC harmonics compliance: EN61000-3-2 + A1 + A2 EMI/RFI compliance: CE, CISPR22 & FCC part 15 class B Safety compliance: VDE, TUV, D, N, S, Fi, UL, C-UL & CB Hold up time, full load: 16ms. typical Efficiency; 100-120VAC and full range: 65% Dielectric withstand, input to frame/ground: 1800VAC, 1sec. Dielectric withstand, input to output: 1800VAC, 1sec. Ripple/noise: 1% MTBF, full load @ 25°C amb.: 100k hrs What do supplies forget to include to sell at higher profits at $40? Things such as over power protection and EMI/RFI compliance. Does your supply specifically state it has this? If not, then that essential function is probably missing which is why they can sell for $40.

Never, ever, ever skimp on a power supply! Period! This sounds like it might be a getter one (it's an Antec) for about $40: http://www.newegg.com/app ViewProductDesc.asp?description=17-103-913&catalog=58&manufactory=BROWSE&depa=1 -- Big Daddy Ruel Smith My SuSE Linux machine uptime: 7:13pm up 44 days 3:58, 2 users, load average: 0.68, 0.45, 0.28 My Windows XP machine uptime: Something less... |

If not, then that essential function is probably missing which is why they can sell for $40. Try and knock an Antec power supply. New Egg has and Antec 350W power supply, model SL350 for $43. Can't beat it. Antec has some of the best power supplies on the market for consumer PC's, bar none. http://www.newegg.com/app ViewProductDesc.asp?description=17-103-913&catalog=58&manufactory=BROWSE&depa=1 -- Big Daddy Ruel Smith My SuSE Linux machine uptime: 7:15pm up 44 days 4:00, 2 users, load average: 0.47, 0.45, 0.29 My Windows XP machine uptime: Something less... |

But...I'm having a hard time narrowing one down...especially in my budget. $40 or less. And preferably at least 350 watts as close to TRUE 350 as possible. Any suggestions, especially 2 fan ones? Why insist on 2 fans when the number of fans isn't closely related to cooling performance? PC Power & Cooling even found 2nd fan in a 550W Enermax to be completely ineffective. If you want maximum cooling with minimum noise, your best choice may be a supply with a single large fan on top, such as some of the newer Fortron-Source and Seasonic models have, although some have said that the F-S with 120mm isn't as quiet as their more conventional models. I found this: http://www.newegg.com/app/ViewProduc...alog=58&depa=1 I don't think I've seen Coolmax on anyone's quality manufacturor's lists...but the numbers (amps and total 3+5+12 line watts) seems pretty good. How do you know the numbers are accurate? The only widely available independent verifications are from AMD and Intel, but they're not very strict, as shown by all the low-quality supplies that get certified. You should also dismiss 99% of the reviews published on the Internet because they don't test with full loads, just a computer running a burn-in program, or 150-200W, nor do they test to failure (when normal shutdown or damage occurs). No review is legitimate unless it includes amp measurements, and the only ones I know of in English that do are www.tomshardware.com (tests to failure, no results given for individual voltage outputs) and www.silentpcreview (tests to full rated loads only). UL says the Coolmax is made by ATNG Power, and it seems to be identical to this one: http://terasan.okiraku-pc.net/dengen/no64/ . This review is typical poor Internet quality, but at least it shows what the supply looks like inside, and my impression is that this hardly the worst made supply, although components alone don't tell the whole story. The inverter transformer (yellow object between the 2 heatsinks) may be on the small side, the heatsinks are fairly small, and the large capacitors are only 820uF. You may want to compare this supply to an Aopen brand Fortron-Source model: http://terasan.okiraku-pc.net/dengen/no47/index.html . I'm sure you've received many recommendations for Fortron-Source power supplies, which Newegg also carries, because they're not only of very good quality and also very cheap, so why have you ignored them and instead considered questionable brands? |

either of these would be good.

Is this not necessary? Thanks for the replies!! Liam |

Ah, I believe they recommend a bottom PSU intake, not a bottom PSU intake *fan*. No? http://www.amd.com/us-en/assets/cont...docs/26003.pdf |

I mean, when you're browsing PS's and you're seeing some with a flat bottom and some with a big-ole fan on the bottom...my mind just assumed the AMD article had been saying fan. =/ Sorry. Well, now to go back and look at some of those Sparkles again! =) |
