Is this a good power supply?

I am just wondering if that is a decent power supply, or if I can find one better for the money. I got a really crappy power supply that I am running that came with the case, and I have been having all sorts of problems with it. So I need a new one pronto!

not bad, but id deffinitly would reconsider getting a better one like antecs PSU. that PSU will do the same as your other PSU and fail

Any suggestions for a better one then?

*edit Nevermind, I saw your edit right after I posted

I will see if I can find an antecs in my price range

I wouldn't even consider using that power supply. The few specifications that are listed on the newegg page are pretty poor, and there are absolutely no specifiications listed on the atrix site. It looks like it is another generic junk power supply with pretty lights intended to sucker in inexperienced people who look for appearance instead of quality. Can't really reccommend a specific power supply without knowing the specifications of the machine it is intended for. The first two threads in the general hardware have a lot of information that is usefull in choosing a power supply and the second one has a list of good/bad brands.

Good:)

*shivers at the sight of such a cheap power supply*

The cheapest one I would go with is this one:

just keep in mind you get what you pay for. Most psu's that come with a case are usually cheap. Except if its an Antec or Enermax case, then its different. Good luck.

Ok, so you're not going to need the best PSU in the world for those parts, but that doesn't mean you should buy a $19 sparkle! That thing will quite possibly die under load and take your parts with it.

I'd recommend the XClio that Blue6007 suggested as a good value, quality unit.

I went with the 300W sparkle. That should be good enough for my parts right? And it was only $30 free 2nd day shipping at zipzoomfly...

[blue60007]

You should be OK, that's not exactly a power hungry system. With 350W I can run a faster processor, more RAM and a power hungry video card, so I bet you'll be fine.

Someone at a PC store told me that wattage is actually the cheapest and easiest form of current to increase in a power supply, and that it is also not the most important for your system. If that is true, then what is the most important factor to investigate in a power supply? Voltage? Ampage? Impedence? I would think they all have the same impedence, but my knowledge of such things is very limited. I am, however, interested in what things to look for in a good power supply since I will undoubtably be doing this again in the future...

hi guys

Can anyone help is there a rule of thumb for power supply wattage size. for CPU,s

CPU AMD sempron 3100+ scoket 754.
Motherboard Tforce 6100 64bit on board graphics Nvidia Geforce 6100.

[Freakitchen]

Yes - wattage is the way PSUs are graded and thus the natural assumption is that increasing this increases the unit's abilities.

Whilst this is technically the case, there is a massive difference between the cheap units and quality units in terms of the actual power they produce.

Take for example, a cheap 500w power supply. 500w is sufficient for high-end systems, but the problem is that 500 is the theoretical maximum that unit can put out, most often measured when the unit is at (or sometimes below) room temperature. The wattage that such units produce decrease with temperature, so you can quickly find that at say 45C, your 500w PSU is putting out 300w or less.

With quality units, you get the power advertised - and thus you're not risking your components with what's known as 'dirty power'. In addition, such units offer other benefits, such as dual 12v rails (one of which is dedicated to supplying power to your CPU), and short-circuit protection, amongst other things.

A good way to tell how 'clean' your power is, is by checking the actual voltage levels on each PSU rail in bios. On the +12v rail, you should be getting as close to 12v as possible. The admin here, GLC, reckons your actual figures should be within 10% of the correct figure - 5% is preferred.

Incidentally, the last no-name PSU I used was producing 16v on the 12v rail...

As Blue said, don't worry too much about this system. Just take these factors into account if you buy a PSU for a higher-end system.

One important thing to look at is the amperage on each of the rails. In the specs you should see something like xA@+3.3V, xA@+5V, xA@+12V, where x = # of amps on that rail. You could compare an expensive xxxW power supply to a cheap xxxW power supply. The cheap power supply is probably lacking on the 12V rail where it is really important.

And Sparkle Power PSUs are actually pretty good quality units.I went with the 300W sparkle. That should be good enough for my parts right?

Ahh, thanks for the correction there Cricket, we don't get that brand in the UK.

this one is a good model
