Long Version: http://www.jonnyguru.com/forums/showthread.php?t=1036Zefah said:Well I went out last night and purchased all of the parts... or so I thought. When I got home I noticed the 640GB Western Digital hard drive that I asked for at the register was not in my bags. Upon checking my receipt I discovered that the clerk didn't even ring it up! Oh well, it was my fault for not checking that everything was there before leaving the store. I'll have to go back later tonight and pick up the hard drive.
This is what I ended up getting:
Motherboard: Gigabyte GA-EP45-UD3P [LGA775/Intel P45/ATX] - Nice
Processor: Intel Core 2 Duo E8500 E0 - Nice
Memory: 4GB (2GB x 2) DDR2 800 RAM from some generic brand called "UMAX". - Run memtest later just in case, always good to do.
Video Card: Radeon HD 4870 512MB (750Mhz clock speed, 3.6Ghz RAM clock speed) - Nice
Optical Drive: Some crazy cheap LG drive that can write Blu-Ray / DVD / CD and read Blu-Ray/ HD-DVD / DVD / CD. -How cheap? :lol
Case: A reasonably priced case from a maker called "AQTIS". It came with a 500W PSU. - Can you read the "RU"/"UL" number from it? The PSU that is
Operating System: Windows Vista Ultimate 64 Bit DSP
I have always been using budget power supplies and haven't really had too many problems. What is the benefit to getting a brandname PSU (Corsair, EarthWatts, Antec, etc...) over a generic one?
See Post
I noticed a few things that cause me some concern. First was that my CPU's clock speed was listed at 2.88Ghz even though I am using an E8500 that should have 3.16Ghz. -Check if the multiplier is at 8.5, 9, or 9.5
38C is fine
I screwed up on attaching the heatsink the first time so I took it off once and reattached it. One of the bolts still didn't give me the "clicking" sound, but it seems firmly attached. -No! Make sure all 4 are FIRMLY seated and have been pushed all the way in. It could pop out eventually, which is not good. You should have the motherboard out of the case to make this 10 times easier.
Short Version: More reliable, reputable wattage ratings, better conversion efficiency (saves you money on electricity), degradation overtime can cause voltages to dip below operational level, killing your PSU and possibly other parts of your computer, a good PSU can even sack itself in the possibility of a surge or outage while protecting the rest of your system.
General rule of thumb about PSU's, the heavier it is, the higher the probability it's a good one.
Worst case scenario of course, but when not spending another $50 or so on the thing that powers your entire system it seems a bit silly to skimp on it.
*Oh and as long as your CPU is under 60C it's all good.
