Hi everyone,

My PSU blew up today and luckily, only took my hard drive with it. I'm looking for a new PSU and Hard Drive, and here are my specs as follows to help you all who are willing to assist me in finding one of each:

-ABIT IL9 PRO Motherboard
-E660 CORE 2 DUO 2.4GHZ
-SEAGATGE BARRACUDA 7200.10 500GB 7200 RPM SATA 3.0Gb/s
-EVGA GEFORCE 8800 GTS 320MB DDR3
-Creative X-tremegamer soundcard
-21" LCD 1080p HDMI/DVI Monitor

Please know that my budget is limited. I'm looking for a good deal, quality PSU and hard drive, preferrably 500GB or somewhat lower, but not significantly. The PSU I'd like to get should be 600W, preferrably no lesser and possibly higher should it be very well worth it. Please consider prices, rebates, instant savings when keeping an eye out for these components - I do not wish to spend more than necessary. Thank you everyone!

ct1615,

Thanks for your response. I looked into your PSU unit, and I like your personal choice. Although, a friend and I had a little trade-off in discussion about PSU's: My PC had a 580W PSU which really only had to work in the past 6 months (because of playing Aion), then it crashed. Would a 600W PSU suffice? or would a 600W PSU working 90% of the time die much faster than a 700W PSU working 50% of the time? Assuming this is how PSU's work...if that's the case, I'd probably buy a 700W to be safe.

the biggest power hog you have is your video card and the 8800 GST 320mb needs nowhere near 600w or even 700w. A very good PSU will outperform a mediocre one even if its down 100w on the label. The corsair one i linked is 650w of continuous power but it will peak at over 700w. Frankly a Corsair 450w is more then enough for your current PC. It will still be enough if you decide to upgrade to an ATI 5770 or Nvidia GTS 250.

Ok, great - the more I save the better. Do you have any evidence to supply the notion that this is all true? (For of course, the sole purpose of purchasing the right PSU and for educational reasons.)

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the +12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the +12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5000 series cards which use less power due to their energy efficiency.

A high quality 500 to 550 watt psu will have a +12 volt rail rated at 40 amps. A high quality 700 to 750 watt psu will have a +12 volt rail rated at 60 amps.

In addition the power supply should be at least 80+ Bronze certified for energy efficiency. There are some models available which have achieved 80+ Silver and 80+ Gold Certifications.

Before purchasing a new psu you will need to decide whether you will eventually have a pc with one or two video cards.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts and Antec TruePower New models which are a major improvement over Antec’s older psu’s like the Basiq models.

Thanks JohnnyLucky. I'm a bit confused on the 12v rail business. Could you furter explain this to me? Assume I know nothing about it. Additionally, my last PSU noted that the +12v was running at 5.6v. Is this bad? I hear that 10% of the .12v number is what's supposed to be displayed when testing voltages. I'm also still confused: is the PSU listed in the above post sufficient to run a single video card as listed in my initial post? Will this provide sufficient energy and provide optimal performance for my cpu components?

The +12 volt rail is one of several voltages that a psu distributes to components. There is an emphasis on the +12 volt rail because it delivers power to the cpu, the video card, any other cards plugged into the motherboard, and a few other components. The +12 volt rail delivers about 75% of the power used by a system.

The standard tolerance for the +12 volt rail is plus or minus 10%. A voltage reading of 5.6 volts is definitely substandard.

Now it's my turn to be confused. I know you listed an EVGA GEFORCE 8800 GTS video card. Which power supply are you referring to? I recommended Corsair and Seasonics and mentioned Antec but I di not specify a model. Are you referring to the OCZ and Corsair models mentioned by ct165? Both models are more than sufficient. In fact both models are overkill for just one video card.

Thank you Johnny, I understand it more clearly now. The PSU I was referring to is: http://www.newegg.com/Product/Product.aspx?Item=N82E168... -

Yes, this was posted by ct165. I seem to be swaying more to that PSU. Now, if you wouldn't mind doing me a favor, and don't laugh! This whole PC was put together by an Engineer at work who recommended it as a "money saver" 3 years ago.

PSU that blew up today: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Video card I have: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Please note, "Minimum of a 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 26 Amps.)" This is stated from the specifications of my graphics card. Does the PSU I'm close to buying fit these standards as well as my other components?

Sunbeam PSU. :lol:  :lol:  :lol: 

I hope the engineer at work is better at his day job than he is at building PC's.

The minimum PSU that I would put in, assuming you do not plan to upgrade:
Corsair 400CX (30 amp 12 volt rail)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I do not particularly like the 450:
Corsair 450VX (33 amp 12 volt rail)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
In terms of usable power (the 12 volt rail), it is not enough of an improvement over the 400CX to be worth it.

My choice would be one of these:
Corsair 550VX (41 amp 12 volt rail)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If you are on a budget, consider one of these:
Antec 500 watt BASIQ
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Yes, it's a Basiq. But this one has been redesigned:

The only Antec PSU I would not buy is the 430W Basiq (it's mediocre, not bad, but I only buy good PSUs). Every other current model (including the 500W Basiq) has received excellent technical reviews at sites like hardwaresecrets, jonnyguru, and hardocp. The same is true of Corsair and Seasonic; none of them make any bad units. I wouldn't choose the 450W Corsair either though, because it is the oldest design of all of them, and less efficient (even though it is 80+). My personal preference for a bottom-dollar but quality PSU is Antec's Earthwatts. The new ones are 80+ bronze.

Okay, I'm a little confused here, guys. I was under the assumption that I should be getting a PSU with more watts, but a quality one. Is 650W going overboard? Everyone's telling me to get something better, but I don't plan on upgrading my CPU within the next year. I'm assuming that 580W Sunbeam PSU either is a terrible brand, or just wasn't putting out much at all...my point here is, is that my PC has really only had to work hard to provide power in the last 6 months since I started playing Aion. And my PSU blowing up was that end result, so in everyone's opinion, should I really be gunning for the PSU's you all are linking?

a quality psu unlike your sunbeam 580 will have active pfc not a lil red switch that is a true sign thats its a POS

3 yr guarantee for a good psu
5yr guarantee for a high end psu

will have least an 80% certification

and will be rated by its Continuous Power not by its MAXIMUM power output and the power will be delivered at 40c or higher


but a good midlle of the range psu thats on a great price right now is the antec eatrwatts 650

Alright, well I looked up some stuff. And, between my core 2 duo and graphic card alone, we're looking at 465W. Any suggestions as to what PSU would be better suited, now that we've established that anything >450W is unacceptable?

khubani - Did you mean "anything less than 450 watts is unacceptable" rather than "anything>450W is unacceptable"?

I recommend the Corsair VX550. It is a high quality, heavy duty power supply that can easily power a pc system with any single video card made. If you decide to upgrade the video card you will not have to spend any additional money for a new psu.

I apologize I wasn't very clear. I was saying anything less than 450W would be unacceptable due to the demand of my components. I also looked at a PSU calculator, and determined it needs 519W total for my system (according to that calculator), so all the more reason not invest in anything within a ~400w range for PSUs.

Now, this Corsair you linked, JohnnyLucky, has less wattage than my last PSU though its quality is not even comparable to the old SunBeam I used to have. I'm afraid here that if I purchase that PSU, that it may not provide sufficient power to graphics card (alone, that needs 400W), and my other components. I was lucky to have my HDD blow out rather than all of my computer parts. Are we absolutely sure that this power supply provided will guarantee sufficient power to all PC components while not under a lot of load?

In other words, will this PSU be working at 100% capacity to provide power? If not, how hard will it be working?

If one of the PSU Calculators told you 519 watts, you did something wrong.
A good quality 450 would be more than sufficient for the specs you have shown, I've run more on a 375 watt Dell power supply.

ok i see what you are trying to say Khubani

your card does not consume 400w, far less so a Corsair 400w PSU has more then enough power for your current system. It peaks far above 400w and probably has just as many amps on its 12v rail (that powers your card) as your old Sunbeam.

What young Johnny is saying, and what I hinted at, is you can drop down to a Corsair 550w, save some money, and have plenty of power for your current system and future upgrades.

According to atx standards the absolute maximum power for one video card cannot exceed 300 watts. I do not know of any video card that uses that much power.
