Buying A New PSU 350W Should Be Safe.right?

Here is the configuration:- AMD Athlon64 X2 5400 Brisbane- 2x1 GB DDR2 800 RAM- HIS Radeon HD3850 256 MB- Caviar Black 500GB- Samsung DVD-RW- 6 USB devices incl. I try searching for one that the same size but they all diffrent sizes, am afraid I buy one and it wont fit? At $299 for the weekend or holiday special from Dell (and a free printer besides!), how much PSU quality do you think you're really getting?Now that I'm done ranting, to answer In even simpler terms: a higher efficiency percentage is better and will require less power from the outlet. http://everfreetech.com/buying-a/buying-a-new-lcd-need-a-little-help.html

In terms of performance both PSUs are good and safe but single rail PSUs are still preferred over multi-rails one. Flag Permalink This was helpful (0) Collapse - could barely run it.? We ended up with 500 W and 750 W PSUs from a brand called Sutai and an additional 420 W unit without an identifying sticker on it. In fact I wanted to buy 4850e or 5050e. http://ask-leo.com/is_it_safe_to_install_a_higher_wattage_power_supply_in_my_computer.html

Unfortunately the only way to test this is to put the suspect power supply into a good PC and see if it fails there too.

  • Generally speaking, most psu's are most effecient around 50% of their rated power.So for example, if you have a computer that might use 300W at full load (with everything working at
  • This rig should beblazing-fast for the next 2-3 years.
  • Nothing could be further from the truth.

pavel_kolarovApr 8, 2016, 9:40 PM My question is simple,but i didn't find any information in the internet,so i am asking here.A week ago my motherboard fried and my cpu died too.Now Here are a few well-known and reputable brands to start you off: Corsair, Cooler Master, Antec, Be Quiet, Seasonic, and XFX. So long as you buy without expecting to run anywhere near its rating for any length of time then they will last for years. by Joe Pishgar May 6, 2011, 4:40 AM News Nvidia Graphics Chip Market Share Nosedives by Douglas Perry May 4, 2011, 11:40 PM The Latest On Tom's Hardware Jury Delivers Judgement

You have a short or faulty component that is over loading the power supply and causing it to fail, are there any hotspots, burning smells when the PS fails?.Problem 3 involves Crashes and glitches can occur if your power supply isn't up to snuff; in fact, the word "glitch" in electronics refers to unwanted electrical pulses that can disrupt circuits. click to read more They have the highest energy efficiency, are quiet, and are made to last longer than all the others.

To calculate the required PSU, multiply the actual load by 1.25 (25% margin). Now apply the 25% margin rule and we arrive at a PSU requirement of 290W (230W x 1.25). Any advice, please share! by zerokewl / October 18, 2009 9:50 PM PDT In reply to: Power supplies for PC's, etc., etc.

Why don't you get what you are told you will get? his comment is here Most often because they have very power hungry videocards that can take up to 300W each.Another reason why people take a larger psu than needed is because of efficiency. It has ample power to drive a modern quad coreplus Radeon 4870 or GTX280 video card.At100% load,we see a2.5% dropin the +12VDC rail, which is still within spec and does not how does one determine what the PSU requirements are???I changed the MB (ABit KT-7a RAID)change the CPU (Athlon TBred 2100+)overclocked it to 1978mHzadded RAM (512M, 512M, 256M)Added disk drives (2x 160G

Even with a high-end NVIDIA graphics card, a high-end ASUS audio card, 4 gigs of high-speed DRAM, a card for adding Firewire 800 ports, and multiple internal hard drives running simultaneously For e.g. I did send questions to several of the PSU manufacturers. this contact form Here's how.

So buying a higher PSU thinking of the future is nonsense. There's no way a 3ghz Pentium is burning up a 750 watt power supply. by R.

According to Anandtech, efficiency can vary between different power supplies, and a more efficient power supply will be more economical in the long run, but there's no real correlation between power

I have a converted server with that chip (I added a decent sound card, a mid range Graphics card, a couple of extra ethernet cards, DVD/RW etc.) and that is running However, these computers only come with a 385 watt PSU.I previously had a HP d5000z only a year ago. Depending on the quality of the psu, it will last as long as it can. Thank you for helping us maintain CNET's great community.
