1. Is it harmful to connect smaller loads such as fans to the Power Supply UNIT and have the connection end there?

2. Is it harmful to other devices (Performance and power wise) if I you connect smaller loads such as a fans to the power Suppyl Unit and connect another load to the fan connector? (Certain fans come with a MALE and female plug allowing you to connect another device and not have the chain of power end at the fan)1) Not at all.

2) You shouldn't go too far. For the most part, as long as you aren't asking more than your PSU can supply, its fine. I mean, you're not thinking of connecting all your devices to one connector, are you?  Thank you.

You seem to know things. What brand of Power Supply unit do you advise?There's plenty of good ones - Enermax, Rosewill, Cooler Master, Thermaltake, OCZ,  Antec, or Zalman (if you're a quiet computer freak who can afford it).What brand would offer me a reasonable price and reasonable performance?

I have a 300 Watt Qtec and a 400 Watt Chieftec. My computer only requires 245 WATTS. What would be the better choice? The Chieftec can make the case temperature rise with 15 to 20 Degrees celcius in a matter of two hours. I think it is malfunctioning as it is even far too warm when the computer is shutdown and on standby voltage.If you have no plans for OVERCLOCKING (thus raising wattage requiremnts), go for the 300 Watt. That gives you plenty of room to maybe add another hard drive or pci or a few extra components. No need to go for a bigger power supply if you don't need it - especially if it causes overheating problems.I was thinking the same thing. I ADDED the 400 Watt Chieftec because someone told me that my rail voltages were low. The difference isn't that great, the rail voltages on the Chieftec are a bit more stable than those on the Qtec (Measured via BIOS) but I am not too well educated on this particular subject, so I really can't tell if switching back is a good choice. I was also reaching the end of the 300 Watt PSU, so it needed to be replaced.

I need a good website where PSU brands are compared, do you happen to know of one?A great website where I buy all my parts is newegg.com. Unfortunately, they only ship to the United States, and I noticed you live overseas. But its still great to look at all the parts they have and compare different PSUs and their specs.Do they compare PSUs?

They don't have articles, but you can read everyone's reviews from people who bought them, and all the tech specs. Otherwise, just google it!  I will try Newegg next time I buy a product to see what the users have got to say.

Usually you can't go wrong with the best rated components there. Most people who buy from Newegg are in the business, enthusiasts, or gamers who are all building the computers themselves, so they know a thing or two. Newegg makes a little effort to only stock quality products as well, so most of their stuff is good, but they stock some cheap stuff too for people on a budget.
